babunello [35]

Solution:

$Z score =\frac{X-\sigma}{\mu}$

1. For Best Actor

$X_{1}$ = 59 years

$\sigma=7.3, \mu=42.0$

Z, Score for best actor named, $Z_{1}$

$Z_{1}=\frac{59-7.3}{42}\\\\Z_{1}= \frac{51.7}{42}\\\\Z_{1}=1.23095\\\\ Z_{1}=1.24$

Z-Score for best actor = 1.24

2. Z , Score for best supporting actor , called $Z_{2}$

$X_{2}$ =49 years

$\sigma=15, \mu=49.0$

$Z_{2}=\frac{49-15}{49}\\\\Z_{2}= \frac{34}{49}\\\\Z_{2}=0.6938\\\\ Z_{2}=0.70$

Z-Score for best supporting actor = 0.70

Z-Score is usually , the number of standard deviations from the mean a point in the data set is.

3. As, $Z_{1}=1.24$

So, we can say that,Option (B) The Best Actor was more than 1 standard deviation above is not unusual.

4.As, $Z_{2}=0.70$

So, we can say that,Option(A) The Best Supporting Actor was less than 1 standard deviation below, is not unusual.

What is the difference between a 30° angle and a -30° angle?

ipn [44]

Answer:

See below

Step-by-step explanation:

A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

5(y-4)=7(2y+1) I need the answer

8_murik_8 [283]

Answer: $y = -3$

Move all terms containing y to the left, all other terms to the right

Add -14y to each side of the equation

$-20 + 5y + -14y = 7 + 14y + -14y$

Combine like terms: 5y + -14y = -9y

$-20 + -9y = 7 + 14y + -14y$

Combine like terms: 14y + -14y = 0

$-20 + -9y = 7 + 0\\-20 + -9y = 7$

Add '20' to each side of the equation

$-20 + 20 + -9y = 7 + 20$

Combine like terms: -20 + 20 = 0

$0 + -9y = 7 + 20\\-9y = 7 + 20$

Combine like terms: 7 + 20 = 27

$-9y = 27$

Divide each side by -9

$-9y/9=27/-9\\y=-3$
