Answer:
31
Step-by-step explanation:
Since the two sides are equal, the two angles are equal
8x-1 = 5x+11
Subtract 5x from each side
8x-5x -1 = 5x-5x+11
3x-1 =11
Add 1 to each side
3x-1+1 =11+1
3x =12
Divide by 3
3x/3 =12/3
x =4
Now we can find WZY
5x+11
5(4)+11
20+11

Answer: 222 cents
Step-by-step explanation: 84/14 = 6 This is the unit rate.
6 x 37 = 222
To solve for proportion we make use of the z statistic.
The procedure is to solve for the value of the z score and then locate for the
proportion using the standard distribution tables. The formula for z score is:
z = (X – μ) / σ
where X is the sample value, μ is the mean value and σ is
the standard deviation
when X = 70
z1 = (70 – 100) / 15 = -2
Using the standard distribution tables, proportion is P1
= 0.0228
when X = 130
z2 = (130 – 100) /15 = 2
Using the standard distribution tables, proportion is P2
= 0.9772
Therefore the proportion between X of 70 and 130 is:
P (70<X<130) = P2 – P1
P (70<X<130) = 0.9772 - 0.0228
P (70<X<130) = 0.9544
Therefore 0.9544 or 95.44% of the test takers scored
between 70 and 130.
