-17+ 1/4 x + 1/4 x + 31 = 24
Answers
______________________________
1.) Combine like terms:[tex]\frac{1}{4}x+\frac{1}{4}x=\frac{1}{2}x[/tex]
- We do this because we need 1 Number/Variable left over.
Equation at the end of Step 1:
[tex]-17+\frac{1}{2}x+31=24[/tex]2.) Add −17 and 31:[tex]-17+31=14[/tex]
- We do this because we can only have 1 number on each side of the equals. (This doesn't count towards the number connected to the variable.)
Equation at the end of Step 2:
[tex]14+\frac{1}{2}x=24[/tex]3.) Subtract 14 from both sides:[tex]14-14=[/tex] Cancels Out[tex]24-14=10[/tex]
- We do this because now we just need the 1 variable and the 1 number on opposite sides of the equal.
Equation at the end of Step 3:
[tex]\frac{1}{2}x=10[/tex]4.) Multiply both sides by 2:[tex]\frac{1}{2}x[/tex] × [tex]2=x[/tex][tex]10[/tex] × [tex]2=20[/tex]- We multiply by 2 since we have a fraction. In this case the reciprocal is 2 meaning we multiply by 2.

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.

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

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 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
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.
