4. A statistician working for the National Basketball Association supplies the television announcers with interesting statistics
Sonbull [250]

Answer: 0.038

Step-by-step explanation:

Given: Total games : n= 375

Number of games won by  the team that was winning the game at the end of the third quarter. = 300

The proportion (p) of the team that was winning the game at the end of the third quarter: p=\dfrac{300}{375}=0.8

Critical z-value for 90% confidence: z* = 1.645

Margin of error =z^*\sqrt{\dfrac{(1-p)p}{n}}

The margin of error in a 90% confidence interval estimate of p =1.645\sqrt{\dfrac{0.2\times0.8}{300}}\\= 1.645\times\sqrt{0.00053333}\\\\=1.645\times0.0231\\\\=0.0379995\approx$$0.038

Hence, the required margin of error = 0.038

Identify the variation as direct, inverse, joint or combined. A = πr^2
Reika [66]

Answer:

1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.

2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased. 

3. F = 4/R. This is inverse variation for the same reason as number 2.

4. m/n = 4. Direct variation. For the same reason as number 1.

5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.

6. R = cl/r². Joint variation.

7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r. 

8. V= pir²h. Joint variation.
