A. 7/11= 7 ÷ 11
B. 5/2= 5 ÷ 2
C. 9/10= 9 ÷ 10
D. 7/15= 7 ÷ 15

A fraction is just a division problem. 7/11 would be considered 7 ÷ 11 (or just 7/11) just do the same for the rest of the fractions.

A television sports commentator wants to estimate the proportion of citizens who "follow professional football." Complete parts
masha68 [24]

Answer:

626 and 654

Step-by-step explanation:

Given that a  television sports commentator wants to estimate the proportion of citizens who "follow professional football."

Part I:

p = 0.48

q=1-p = 0.52\\se = \sqrt{\frac{pq}{n} } \\\frac{0.4996}{\sqrt{n} } =

Margin of error =2.045*\frac{0.4996}{\sqrt{n} }626

Sample size should be >626

Part II:

If unknown we take p = 0.5 because maximum std error for this

Here everything would be the same except insted of 0.48 we use 0.5

Margin of error = 2.045*\sqrt{\frac{0.5}{\sqrt{n} } } 654

-------------------------

a and b are too close because 0.46 proportion is close to part b proporti0n 0.5

Find the product: (30 gallons 3 quarts 1 pint) × 5
SpyIntel [72]
30 gallons * 5 = 150 gallons

3 quarts * 5 = 15 quarts 

1 pint * 5 = 5 pints

Four quarts in a gallon: 15/4 = 3 gallons, 2 quarts

2 pints in a quart: 5/2 = 2 quarts, 1 pint

2 quarts + 2 quarts = 1 gallon

150 + 3 + 1 gallons + 1 pint = 153 gallons, 1 pint.
