Answer:
254
Step-by-step explanation:
The median of a set of data is basically the middle number of the data when placed in least to greater order.
example:
1,2,3,4,5,
in this case (the example) the median is 3 becasue it is the middle number of the 5 numbers (thier are two numbers to the left of 3 and 2 numbers to the right of 3)
Going back to the question being asked if you put that data in order you would get a sequence of
154, 205, 244, 244, 253, 254, 263, 274, 276, 389, 431
now try eliminating a number from each end side one by one (alternating) until you have one number left.
For instance remove 154 and 431, then remove 205 and 389 etc
IF DONE CORRECTLY you would have 254 as the remaining number.
Answer:
254
Step-by-step explanation:
First, put the numbers in order.
431, 154, 254, 244, 244, 276, 263, 389, 253, 274, 205
154, 205, 244, 244, 253, 254, 263, 274, 276, 389, 431
The median of a data set is the middle number.

Quita bought a jacket priced at $88. The sales tax rate on the jacket was 7.5%. How much was the sales tax in dollars and cents on this jacket?
Need help !!!
Answer:
i think the answer is 3.3
Step-by-step explanation:
Final answer:
Quita paid $6.60 in sales tax for an $88 jacket.
Explanation:
To calculate the sales tax Quita had to pay for her jacket, we need to follow a simple two-step process.
First, we will calculate the amount of tax by converting the percentage to a decimal and then multiplying it by the price of the jacket.
Since the tax rate is 7.5%, we convert this to a decimal which gives us 0.075.
Then, we multiply this decimal by the price of the jacket:
Amount of sales tax = price × rate of sales tax
$88.00 × 0.075 = $6.60
So, the sales tax on the jacket priced at $88 is $6.60.

There are 43 students in a classroom with 5
tables. If 8 students can sit at a table, how
many students cannot sit down at tables?
5
Answer:
3
Step-by-step explanation:
8 x 5 = 40
43 - 40 = 3
The number of students who cannot sit at tables based on the given conditions in a classroom setting are 3.
The number of students who cannot sit at tables can be calculated as follows:
Number of students per table = 8
Total number of students = 43
Total number of students that can be accommodated by tables = 5 tables x 8 students = 40 students
Number of students who cannot sit at tables = Total number of students - Total number accommodated by tables = 43 - 40 = 3 students

D. 128
Answer:
A
Step-by-step explanation:
To calculate this, we shall be selecting 2 each from a total of 64
This is a combination question and our required answer is 64C2
Mathematically, if we are to select r from n items , the combination can be computed as follows;
nCr = n!/(n-r)!r!
Thus, we have 64C2 as ; 64!(64-2)!2! = 64!/62!2!

What is the value of
Answer:
61°
Step-by-step explanation:
∠SPQ is a straight line, so it equals to 180°.
∠SPR is 119° and since we're looking for ∠QPR, we subtract 119° from 180°.
180° - 119° = 61°, so ∠QPR = 61°
Answer:
61 degrees
Step-by-step explanation:
Because SPQ is said to be a straight line, we know that a straight line in this kind of equation is equal to 180 degress.
Since we already know the measure to one angle (119), we would need to find the difference between 180 and 119, meaning we'd have to subtract.
(180-119)
Then we would just get the sum, which in this case, is 61 degrees.
A state park has a normally distributed daytime temperatures in the month of June. The mean temperature is 75 Fahrenheit and then standard deviation of 7. What is the probability the temperature is above 82F?
Answer:
0.16
Step-by-step explanation:
This probability is the area under the standard normal curve to the right of 82. Note that 82 is ONE standard deviation above the mean: 75 + 7 = 82.
According to the Empirical Rule, 68% of data lies within one standard deviation of the mean. In other words, 34% lies between the mean and one standard deviation above the mean. The remaining area under the standard normal curve is thus (100% - 68%), or 32%. Half of that is 16%.
The probability that the temperature is above 82, or above 1 standard deviation above the mean, is 16%, which we can also express as 0.16.
Alternatively, use a calculator with built-in statistical functions. In this case the desired result is found by executing the following command:
normcdf(82, 10000, 75, 7). The desired result is 0.1587, or approximately 0.16.

A trapezoid has base lengths of 4 and 19 feet, with an area of 115 square feet.What is the height of the trapezoid? *
Your answer
Answer:
10 ft
Step-by-step explanation:
area of trapezoid = (B + b)h/2
where B and b are the lengths of the bases, and h is the height.
A = (B + b)h/2
115 = (19 + 4)h/2
230 = 23h
23h = 230
h = 10
Answer: 10 ft
The height of the trapezoid with base lengths of 4 and 19 feet and an area of 115 square feet is 10 feet.
What is a Trapezoid?A trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.
The area of a trapezoid is given as half of the product of the height(altitude) of the trapezoid and the sum of the length of the parallel sides.
[tex]\rm{ Area\ of\ trapezoid = \dfrac{1}{2} \times Height \times(Sum\ of\ parallel\ sides)[/tex]
The area of a trapezoid is given as half the product of the sum of the parallel sides and the height of the trapezoid.
The length of the parallel sides of the trapezoid is 4 and 19 feet, while the area of the trapezoid is 115 square feet. Therefore, the height of the trapezoid is,
115 ft² = 0.5 × (4 ft + 19 ft ) × height
115 ft² = 0.5 × 23 ft × height
height = (115 ft²)/ (0.5 × 23 ft)
height = 10 feet
Hence, the height of the trapezoid is 10 feet.

Find 3 consecutive integers whose sum is 105.
Answer:
34 + 35 + 36 = 105
Step-by-step explanation:
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 105
3X + 3 = 105
3X + 3 - 3 = 105 - 3
3X = 102
3X/3 = 102/3
X = 34
Which means that the first number is 34, the second number is 34 + 1 and the third number is 34 + 2. Therefore, three consecutive integers that add up to 105 are 34, 35, and 36.
34 + 35 + 36 = 105
We know our answer is correct because 34 + 35 + 36 equals 105 as displayed above.

Fidelity Investments is selling a real estate income mutual fund for $10.94 per share. The fund charges a load of 2.5%. What is the offer price?
Answer:
Step-by-step explanation:
The fidelity investment mutual funds is $10.92 per share.
The fund charges 2.5%.
So, if 2.5% is charged,
Then, 2.5% of the share is
2.5% of $10.92 = 2.5 / 100 × $10.92
2.5% of $10.92 = $0.273
Then, total offer price is 0.273 + 10.92
Therefore, total offer is $11.193
Final answer:
The offer price of the real estate income mutual fund from Fidelity Investments is $11.2135 per share.
Explanation:
The offer price of the real estate income mutual fund from Fidelity Investments can be calculated by adding the load to the selling price per share. In this case, the load is 2.5% of $10.94 per share. To find the load amount, multiply 2.5% by $10.94, which is equal to $0.2735.

Find the area of the shaded segment of the circle.
Answer:
Around 55.9
Step-by-step explanation:
The first step is to find the area of segment of the circle. Since the segment is a 90 degree angle and a total circle is 360, it is a quarter of the area of a circle. Therefore, you can find its area with the formula [tex]\frac{1}{4}\pi r^2=49\pi[/tex]. Now, you can find the area of the triangle inside.

A theatre sells two types of tickets to their plays; children’s tickets and adult tickets. For today’s performance they have sold a total of 1180tickets. Also, the have sold 80 more adult tickets than children’s tickets. How many adult tickets have they sold?
Answer:
630
Step-by-step explanation:
Let the number of adult tickets be a.
Let the number of children tickets be c.
For that day's performance, they have sold a total of 1180 tickets. That means that:
a + c = 1180 _____________ (1)
Also, they have sold 80 more adult tickets than children’s tickets.
This means that:
a = c + 80 ______________(2)
Putting (2) in (1):
c + 80 + c = 1180
2c + 80 = 1180
Collecting like terms:
2c = 1180 - 80
2c = 1100
c = 1100 / 2 = 550
From (2):
a = 550 + 80
a = 630
They sold 630 adult tickets.
Final answer:
The theatre has sold 630 adult tickets after solving a system of equations based on the given conditions of total tickets sold and the difference between adult and children's tickets.
Explanation:
The student is presented with a problem where a theatre sells two types of tickets: children's and adult's tickets. For a particular performance, a total of 1180 tickets were sold, and there are 80 more adult tickets sold than children's tickets. We can let 'x' represent the number of children's tickets sold, and thus 'x + 80' will represent the number of adult tickets sold. According to the information given:
x + (x + 80) = 1180
Solving for 'x' we get:
2x + 80 = 1180
2x = 1100
x = 550
Now, to find the number of adult tickets sold, we add 80 to the number of children's tickets.
x + 80 = 550 + 80
x + 80 = 630
Therefore, the theatre has sold 630 adult tickets.
Let R1 and R2 are the remainders when the polynomials x^3 + 2x^2 − 5ax − 7 and x^3 + ax^2 − 12x + 6 are divided by x + 1 and x − 2 respectively. If R1+R2 = 6, find the value of a.
Answer:
2.44
Step-by-step explanation:
Given: x³ + 2x² - 5ax - 7 and x³ + ax² - 12x + 6
Also, R1 + R2 = 6
in order to find the value of a:
Let p(x) = x³ + 2x² - 5ax - 7 and q(x) = x³ + ax² - 12x + 6
Using remainder theorem i.e if a polynomial p(x) is divisible by polynomial of form x - a then remainder is given by p(a).
Then,
R1 = p( -1 ) = (-1)³ + 2(-1)² - 5a(-1) - 7 = -1 + 2 + 5a - 7 = 5a - 6
R2 = q( 2 ) = 2³ + a(2)² - 12(2) + 6 = 8 + 4a - 24 + 6 = 4a - 10
Now,
R1 + R2 = 6
5a - 6 + 4a - 10 = 6
9a = 22
a=2.44
Therefore, Value of a is 2.44

6 people sharing 40 lbs of gold evenly. How many do they get? Then subtract 1 2/3 from the result of the problem above & simplify completely. Please help cause it's not accepting what I have
Answer: 6
Step-by-step explanation:
Given Data:
Number of people = 6
Amount of Gold to be shared = 40lbs
Subtract 2/3 from your answer.
Therefore
If six people are to share 40lbs of gold evenly
= 40lbs / 6
Divide through by 2
= 20lbs / 3
= 20lbs / 3 - 2/3

1. Each individual gets [tex]6\frac{2}{3}lb[/tex] of gold
2. After subtracting by [tex]1\frac{2}{3}[/tex] , the result is 5
Step-by-step explanation:
Given
Size of Gold = 40 lbs
Number of people = 6
Required
1. Proportion of each individual
2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion
1. Proportion of each individual
To calculate how many each individuals get (in other words, the proportion of each individual), we simply divide the total size of gold by the number of people
Mathematically,
[tex]Proportion = \frac{Total}{People}[/tex]
[tex]Proportion = \frac{40}{6}[/tex]
Reduce fraction to lowest term by dividing numerator and denominator by 2
[tex]Proportion = \frac{20}{3}[/tex]
Convert to mixed fraction
[tex]Proportion = 6\frac{2}{3}[/tex]
Hence each individual gets [tex]6\frac{2}{3}lb[/tex] of gold
2. Subtract [tex]1\frac{2}{3}[/tex] from each proportion
This is represented by
[tex]6\frac{2}{3} - 1\frac{2}{3}[/tex]
Convert both fractions to improper fractions
= [tex]\frac{20}{3} - \frac{5}{3}[/tex]
Find LCM of both fractions
= [tex]\frac{20 - 5}{3}[/tex]
Subtract

Y units: 100 feet
X/20 = 4/5
X = 20 × 4/5
X = 16
Y/100 = 4/5
Y = 100 × 4/5
Y = 80
The cut wedge represents one-eighth of the cheese. A. Find the surface area of the cheese before it is cut in terms of π ,rounded to the nearest whole number, and as a decimal, round to the nearest tenth. The surface area of the cheese before it is cut is π , or about in.2 2 . B. Find the surface area of the remaining cheese after the wedge is removed. Round the estimated portion of the answer to the nearest whole number. The surface area of the remaining cheese after the wedge is removed is about square inches. Question 2 Did the surface area increase, decrease, or remain the same? Response - correct The surface area decreased.
Answer:
A. The surface area of the cheese is 24·π in.² or 75.40 in.²
B. The surface area of the remaining cheese after the wedge is removed is about 72 in.²
2. The surface area decreased
Step-by-step explanation:
From the figure attached to a similar question, we have;
Radius, r of cheese = 3 in.
Height, h of the cheese = 1 in.
A. The surface area of the cheese is equal to the area of two circles, one on top and the other underneath added to the surface area of the sides which is equivalent to the surface area of a cylinder given by the relation
Surface area of the cheese = 2×π×r² + 2×π×r×h
∴ Surface area of the cheese = 2×π×3² + 2×π×3×1 = 24·π in.²
Surface area of the cheese = 24·π = 75.398 ≈ 75.40 in.² to the nearest 10th
B. The surface area of the remaining cheese after the wedge is removed is found by first subtracting the cut wedge from the total surface area as follow
Outer surface area of cut wedge = 24·π÷8 = 3·π
New outer surface area = Total surface area - Removed outer surface area
∴ New outer surface area = 24·π - 3·π = 21·π
New total surface area = New outer surface area + Area of newly exposed segment
Area of newly exposed segment = 3 × 1 × 2 = 6 in.²
∴ New total surface area = (21·π + 6) in.² = 71.9734 in.² ≈ 72 in.²
The surface area of the remaining cheese after the wedge is removed is about 72 in.²
2. The surface area decreased.
Answer:
A. The surface area of the cheese is 24·π in.² or 75.4 in.² B. The surface area of the remaining cheese after the wedge is removed is about 72 in.² 2. The surface area decreased
Step-by-step explanation:
It's 75.4 instead of 75.40, thank me please.
