The sum of angles on a straight line is 180degrees. The measure of the value of x from the figure is 98degrees
Sum of angle on a straight lineThe measure of angles 82 degrees and the unknown are on a straight line, Since the sum of angles on a straight line is 180degrees, hence;
x + 82 = 180
Subtract 82 from both sides
x + 82 - 82 = 180 - 82
x = 180 - 82
x = 98 degres
Hence the measure of the value of x from the figure is 98degrees

There are about 4200 college presidents in the United States, and they have annual incomes with a distribution that is skewed instead of being normal. Many different samples of 40 college presidents are randomly selected, and the mean annual income is computed for each sample. What is the approximate shape of the sample means?
Answers
Final answer:
The distribution of sample means for college presidents' incomes, based on many different samples of size 40, will approximate a normal distribution due to the Central Limit Theorem.
Explanation:
The question regarding the distribution of sample means for college presidents' incomes pertains to a concept in statistics known as the Central Limit Theorem. When dealing with a population whose distribution is skewed, the distribution of sample means tends to become approximately normal if the sample size is large enough, which is usually considered to be over 30. As multiple samples of size 40 are taken in this case, the distribution of the sample means for the college presidents' annual incomes should approximate a normal distribution.

Answers
Harvey earned a simple interest of $660 over 2 years on his $6000 investment.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since, We know that;
Simple interest is calculated using the formula:
I = P r t
Where: I = Interest earned P = Principal amount (amount invested) r = Annual interest rate t = Time period (in years)
Now, In this case,
Harvey invested $6000 for 2 years at an annual interest rate of 5.5%.
So, using the formula:
I = 6000 x 0.055 x 2

A dealer dealt the following cards from a shuffled deck: 3 , 2 , 2 , A , K , Q , K , 5 , 2 , 6 4 , 5 , K , 2 , 7 , 6 , A , J , J , A What was the experimental probability of dealing a black card?
Answers
Answer:
Total number of cards in shuffled deck=3 , 2 , 2 , A , K , Q , K , 5 , 2 , 6, 4 , 5 , K , 2 , 7 , 6 , A , J , J , A .
Total number of cards in a deck of card = 52 cards, out of which 26 are black cards and 26 are red card.
As, it is not given that out of the 20 cards dealt by dealer is either red card or black card.
A=3=2B +1 R or 1 B + 2 R
2=4=2 R +2 B
3=1=1 R or 1 B
4=1=1R or 1 B
5=2=2 R or 2 B
6=2=2 R or 2 B
7=1=1 R or 1 B
8=0
9=0
10=0
J=2= 2 R or 2 B
K=3= 2 R + 1 B or 1 R +2 B
Q=1=1 R or 1 B
If you count total number of black cards among the number of cards dealt by dealer, the possibilities of black card drawn is either 15 or 16 from 20 cards drawn.
As, Experimental probability is the probability obtained through experiment which is different from theoretical Probability.
Total number of cards =52
So, Probability of dealing with black cards by dealer which is either 15 or 16 in number is given by
[tex]=\frac{\text{total favorable outcome}}{\text{total possible outcome}}\\\\\frac{15}{52} {\text{or}} \frac{16}{52}=\frac{4}{13}.[/tex]
40%
Step-by-step explanation:There are 20 cards in total.
8 are black: 3,2,K,5,6,4,A,J
12 are red: 2,A,K,Q,2,5,K,2,7,6,J,A
so that means 8 of the 20 are black or 8/20
and 8/20 is 40% which is your answer.

Answers
Suppose we go from (0,3) to (7,-28.5).
-28.5-3 -31.5
Then the slope, m, is m = ------------- = ---------- = - 9/2, or - 4.5.
7-0 7
Let's check this result!
Suppose that y = mx + b governs the relationship between x and y.
Then y = -4.5x + b
suppose we find b by substituting the coordinates from the point (0,3):
3 = -4.5(0) + b
Then b = 3, and y = -4.5x + 3. Does the point (-2,12) satisfy this equation?
Does 12 = -4.5(-2) + 3? Does 12 = 9 + 3? YES.
So y = -4.5x + 3 is the equation from which these points came, and the rate of change of y with respect to x is the slope m = -4.5, or m = -9/2.

What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Let's say 0.6 is 10 times as much as x
Then,
0.6 = 10x

A student must take one physics, one chemistry, and one mathematics course during their junior year of high school. There are three courses to choose from for physics (P1, P2, P3), two courses to choose from for chemistry (C1, C2), and two courses to choose from for mathematics (M1, M2). How many possible combinations are there for the three physics, chemistry, and mathematics courses a student could select?
Answers
P1 C1 M1
P1 C1 M2
P1 C2 M1
P1 C2 M2
So there are 4 possible choices with P1. Since there are 3 choices of P, there are 3*4 total combinations, or 12. In general, you can multiply the number of possibilities together to see how many total combinations can occur, I just wanted to illustrate why that works.

Answers
Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age = h-2.
The sum of their ages is 92, therefore
h + (h-2) = 92
2h - 2 = 92
2h = 94
h = 47 years
Answer:
The equation to find Hannah's age is 2h - 2 = 92.
This yields Hannah's age as 47 years.

Find the point p where the line x = 1 + t, y = 2t, z = -3t intersects the plane x + y - z = 3.
Answers
x = 1 + t
y = 2t
z = -3t
The plane is x + y - z = 3
If the lines intersect the plane at a point p, then the lines should satisfy the equation of the plane.
That is,
(1 + t) + (2t) - (-3t) = 3
1 + t + 2t + 3t = 3
1 + 6t = 3
6t = 2
t = 1/3
Therefore the coordinates of the point p are
x = 1 + 1/3 = 4/3
y = 2(1/3) = 2/3
z = -3(1/3) = -1
That is p (4/3, 2/3, -1)
Answer: The point p has coordinates (4/3, 2/3, -1)

Answer:
Which function has an inverse that is also a function? a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} b {(–1, 2), (0, 4), (1, 5), (5, 4), (7, 2)} c {(–1, –2), (0, 4), (1, 3), (5, 14), (7, 4)} d {(–1, 4), (0, 4), (1, 2), (5, 3), (7, 1)}
Step-by-step explanation:
It is called the inverse or reciprocal function of f to another function f − 1 that fulfills that:
If f (a) = b, then f − 1 (b) = a.
The inverse of a function when it exists is unique, so that neither "X" nor "Y" can be repeated.
If we analyze the possibilities, in the case of b, c, and d, the value 4 of the "Y" is repeated twice; in the case of a, that does not happen, therefore the answer is: a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2) }
It takes 40 min for a bus to travel the 36 miles from Framingham to Worcester. A car traveling from Worcester to Framingham moves 1.5 times as fast as the bus. If the car and the bus start moving towards each other simultaneously, after how many minutes will they meet?
Answers
The velocity of the bus is:
velocity (bus) = 36 miles / 40 min
velocity (bus) = 0.9 miles / min
Since the car is 1.5 times faster, so the velocity of the car is:
velocity (car) = 1.5 * 0.9 miles / min
velocity (car) = 1.35 miles / min
At the meeting point, the sum of the distance is equal to 36 miles. Therefore:
1.35 t + 0.9 t = 36
2.25 t = 36
t = 16 min
So they will meet after 16 minutes.
a rectangular flower garden has area of 32 square feet. if the width of the garden is 4 feet less than the length, what is the perimeter, in feet, of the garden?
Answers
length= x
width=x-4
area = 32
length * width=32
x(x-4)=32
x^2 - 4 x -32=0
(x-8)(x+4)=0
x=8 feet
length=8 feet
width=4 feet
perimeter=2(len+wid)
=2(8+4)
2*12=24 feet
To find the perimeter of the rectangular flower garden, we first need to find its dimensions. Once we have the length and width, we can calculate the perimeter by using the formula: P = 2(length + width). Therefore, the perimeter of the garden is 4x - 8 feet.
Explanation:To find the perimeter of the rectangular flower garden, we first need to find its dimensions. Let's use x to represent the length of the garden.
According to the problem, the width of the garden is 4 feet less than the length, so the width would be x - 4.
The area of the garden is 32 square feet, so we can set up the equation: x * (x - 4) = 32.
We can solve this equation by factoring or by using the quadratic formula to find the length.
Once we have the length and width, we can calculate the perimeter by using the formula: P = 2(length + width).
Substituting the values, we get P = 2(x + x - 4), which simplifies to P = 4x - 8.
Therefore, the perimeter of the garden is 4x - 8 feet.
