Step-by-step explanation:
7. The two coordinates are (0, 4) and (1, -4).
To find the slope you would need to use the formula [tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]
[tex]y_{2}[/tex] = (-4), [tex]y_{1}[/tex] = 4
[tex]x_{2}[/tex] = 1, [tex]x_{1}[/tex] = 0
[tex]\frac{(-4)-4}{1-0}[/tex] = [tex]\frac{-8}{1}[/tex] = -8
8. The coordinates, (1, 4) and (0, -2)
(-2) -4 / 0 -1 = -6 / -1 = 6
Sorry for not formatting 8
9. The coordinates (-1, 3) and (4, -1)
(-1) - 3/ 4 - (-1) = -4/ 5
10. The coordinates (1, -1) and (2, -2)
(-2)- (-1) / 2 -1 = -1 / 1 = -1
Hope this helps!!!

The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W = 7+2X. What are the mean and standard deviation of W?
A. The mean is 24, and the standard deviation is 6.
B. The mean is 24, and the standard deviation is 13.
C. The mean is 31, and the standard deviation is 3.
D. The mean is 31, and the standard deviation is 6.
E. The mean is 31, and the standard deviation is 13.
Answers
Answer: D. The mean is 31, and the standard deviation is 6.
Step-by-step explanation:
Given the data :
X = mean = 12 ; Standard deviation = 3
W = 7 + 2x
Variance of W = 2x
Variance = Standard deviation²
(2x)² = 4x²
Variance
Standard deviation of X = 3
Variance (W) = 4*3² = 4 * 9 = 36
Variance (W) = 36
Standard deviation = sqrt(variance)
Standard deviation = sqrt(36) = 6
Mean ; of x = 12
Mean(W) = 7 + 2(12)
Mean = 7 + 24
Mean = 31
how do you solve 9 tenths minus 13 fiftenths
Answers
Answer:
0.04
Step-by-step explanation:
1. 9/10 = 0.9 and 13/15 = 0.86
2. Subtract 0.9 and 0.86
3. You should end up with 0.04
Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.

In basketball, Nicole makes 4 baskets for every 10 shots. If she takes 3 shots, what is the probability that exactly 2 of them will be baskets
Answers
Answer:
0.288
Step-by-step explanation:
Calculation for what is the probability that exactly 2 of them will be baskets
In order for us to find the probability that exactly 2 of them will be baskets we would have to make use of binomial distribution using Microsoft Excel
P =4 baskets/10 shots=0.4,
x = 2
n = 3 shots
P(2)=BINOMIAL DISTRIBUTION(2,3,0.4,FALSE)
P(2)=0.288
Therefore the probability that exactly 2 of them will be baskets is 0.288

In the diagram below, the three lines intersect in the same point, forming six numbered angles.
Answers
For the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.
Given that, A figure of the intersecting lines is given where 3 lines intersect at the same point.
What is the angle?The angle can be defined as one line inclined over another line.
What is a Line?A line can be defined by the shortest distance between two points is called a line.
Here,
From the figure
∠1 = ∠4
∠2 = ∠5
So,
∠6 = ∠3
Now, from the option, the property hold is m∠1 + m∠3 + m∠5 = 180°. because m∠1 + m∠6 + m∠5 = 180°, or ∠6 = ∠3.
Thus, for the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.

6051 was rounded to the nearest one. What is the lower bond ?
Answers
Answer:
6050.5
Step-by-step explanation:
The key to this is "rounded to the nearest one"
If the question was to say "round to the nearest 10" you would do 10÷2 = 5
Always divide by 2
1 ÷2 = 0.5
6051 - 0.5 = 6050.5
If it was upper bond it would be:

Your grade before taking the final exam is 493pts out of 510 possible points. The final exam is worth 100 points. How many points do you have to get on the final exam to get 93% overall for the class
Answers
Answer:
You need 75 points.
Step-by-step explanation:
Giving the following information:
Total number of points= 510 + 100= 610 (100%)
Actual number of points= 493
First, we need to determine the number of points required to reach 93%:
Points required= 610*0.93
Points required= 567.3 = 568
Now, the points needed in the final exam:
Difference of points= 568 - 493
Difference of points= 75 points
You need 75 points.

Answers
Answer:
x = 121°
Step-by-step explanation:
If you add up all the angles of a triangle, you get 180°.
So you must add up all the angles.
[tex]27+32+x=180\\\\59+x=180[/tex]
Next you subtract 59 on both sides.
[tex]x=121[/tex]
x should be 121°.
If you would like to check your answer, you can add up 27, 32, and 121. If it all equals to 180, then your answer is correct.
In the balance scale/equation analogy, what should you write in the blank on the right side of the equation in order to balance the scale for the following equation? 2(x + 1) = 2x + ______
(x + 1)
4
x
2
Answers
Answer:
Option D: 2 is the correct answer.
Step-by-step explanation:
Given equation is:
2(x + 1) = 2x + ______
For balancing the equation, the variables and constants must be same on both sides of the equation.
Simplifying 2(x+1) gives us 2x+2
As 2x is already there, we will add 2 with it in the equation.
Hence,
Option D: 2 is the correct answer.
