The dot plot shows how many attempts it took for each student to complete a puzzle:
Is the median or the mean a better measure of center for these data and why?
Mean, because the data are skewed and there are outliers
Mean, because the data are symmetric and there are no outliers
Median, because the data are skewed and there are outliers
Median, because the data are symmetric and there are no outliers
Answers
Answer: Mean, because the data are symmetric and there are no outliers.
Step-by-step explanation:
The given dot plot shows how many attempts it took for each student to complete a puzzle.
From the given dot plot, we observe that it has no outlier and the data is symmetric.
Therefore , the mean is a better measure of center for these data because mean the data are symmetric and there are no outliers .
"If a data is skewed or has outliers, then we choose median to measure the center of data over mean."
A commuter has $245 in his commuter savings Account. This account changes by -$15 each week he buys a ticket.
A- if the account changes by -$240, for how many weeks of tickets did the commuter buy?
B- if the commuter wants to buy 20 weeks of tickets, how much must he add to his accoumt?
Answers
if the account changes by -240......240/15 = 16....so he bought 16 weeks of tickets
if he wants to buy 20 weeks....and the tickets cost 15 bucks...he would have to add (20 * 15) = 300 bucks.....thats if he doesn't have any in his account
Using synthetic division, how do you know if a given value is a root of a polynomial function?
Answers
Final answer:
A given value is a root of a polynomial function if, after using synthetic division, the remainder is zero. The remainder is found in the last position of the bottom row after performing synthetic division with the given value.
Explanation:
To determine if a given value is a root of a polynomial using synthetic division, follow these steps:
Write down the coefficient of the polynomial.
Place the value you want to test for being a root (let's call it 'c') to the left of the coefficients.
Bring down the leading coefficient to the bottom row.
Multiply 'c' by the value you just brought down and write the result underneath the second coefficient.
Add the second coefficient to the product you just wrote down and write the sum in the bottom row.
Repeat the multiplication and addition process until you reach the end of the row.
If the last number in the bottom row, which represents the remainder, is zero, then 'c' is a root of the polynomial. If the remainder is not zero, 'c' is not a root.
Understanding how to perform such operations is essential, especially when dealing with complex equilibrium problems where square roots, cube roots, or higher roots come into play. If unsure about carrying out these operations, particularly on a calculator, it is advisable to seek assistance from your instructor.

Answers
Turn 25% into a decimal and you would get .25
Then multiply that by 15 and you would get $3.75
$15.00 minus $3.75 you would get $11.25
The basketball would cost $11.25.

Calculate the average of 7081 and 8890
Answers
The average of 7081 and 8890, is 7985.5.
Calculating the Average
To calculate the average of two numbers, you add the numbers together and then divide the sum by 2.
Here are the steps:
Add the numbers: 7081 + 8890Sum: 15971Divide the sum by 2: 15971 / 2Result: 7985.5Therefore, the average of 7081 and 8890 is 7985.5.

The x-coordinate of the solution to the system of equations is __________.
Answers
The x-coordinate of the solution to the system of equations is 1 unit.
What is a system of equations?"A 'system' of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables."
"A solution for a single equation is any point that lies on the line for that equation. A solution for a system of equations is any point that lies on each line in the system."
Since, the given equation are
[tex]y = -x - 2[/tex] ----------------------- eq 1
and [tex]y = 2x - 5[/tex] -------------------eq 2
now solving them,
subtracting eq 2 from eq 1
we get,
3x = 3
x = 1 and y = -3
Hence, the x-coordinate of the solution to the system of equations is 1 and y coordinate is -3.

A kite’s diagonals WY and ZX intersect at point V. Which of the following are true? Select all that apply.
1.)∠WVX = 90°
2.)∠ZVY = 90°
3.)WY is parallel to ZX
4.)WY is perpendicular to ZX
5.)WY = ZX
Answers
Answer: The correct options are
(1)∠WVX = 90°,
(2) ∠ZVY = 90°
and
(4) WY is perpendicular to ZX .
Step-by-step explanation: Given that WY and ZX are the diagonals of a kite that intersect at the point V.
We are to select the correct statements from the given options.
KITE: A quadrilateral having adjacent sides congruent and the diagonals bisect each other perpendicularly.
As shown in the attached figure, WY and ZX are the diagonals of the kite WZYX.
Since WY and ZX intersect at the point V, so they will bisect each other perpendicularly.
That is, WY is perpendicular to ZX. And, also
∠WVZ = ∠WVX = ∠ZVY = ∠XVY = 90°.
Since WZ is perpendicular to ZX, so they cannot be parallel.
Also, since the diagonals of a kite may not be equal, so WY ≠ ZX.
So, options (3) and (5) are incorrect.
Thus, the correct options are
(1)∠WVX = 90°,
(2) ∠ZVY = 90°
and
(4) WY is perpendicular to ZX .

the nutritional chart on the side of a box of cereal states that there are 93 calories in a 3/4 cup serving how many calories are in 5 cups of cereal
Answers
5 / 3/4 = 5/1 * 4/3 = 20/3 = 6 2/3
6 2/3 * 93 = 20/3 * 93/1 = 1860/3 = 620 calories
Cross multiply
.75x = 5*93
.75x = 465
Divide both sides by .75
x = 620 calories
Highlighter pens cost $3.86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets of these pens? n = 3.86P P equals 3.86 over n n equals 3.86 over P P = 3.86n
Answers
Meaning N as the number of sets and P as the total price of the # of sets times the unit price.
P=Price
N=Number of pens you buy
The price depends on the number of pens that you buy. Each pen costs $3.86, so you will have to multiply the price of each pen by the number of pens that you buy and it will give you your price to pay.

x(rounded to the nearest tenth) = 0.70
Answer:
The percentage of discount is 31.0 % ( approx )
Step-by-step explanation:
Given,
The original price = $ 24,365
Selling price = $ 16,820
Thus,
[tex]\text{The percentage of discount}=\frac{\text{Original-Selling price}}{\text{Original price}}\times 100[/tex]
[tex]=\frac{24365-16820}{24365}\times 100[/tex]
