larisa [96]

Answer:

Step-by-step explanation:

No of citizens participated in the survey =n =500

No of people who believe the government's highest priority should be foreign relations.=70

Sample proportion = p = $\frac{70}{500} =0.14$

q = 1-p = 1-0.14 = 0.86

Std error of proportion= $\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.14*0.86}{500} } \\=0.01552$

Concept used:Sample proportion p follows a normal distribution with mean =p and std error = sq rt pq/n

y = ($30/hr)(x)

For a 40 hour week, Denise earns:

y = ($30/hr)(40 hr/week)

An art class is planning to paint a rectangular mural with an area of 60 square feet. It has to be at least 4 feet high but no m

Strike441 [17]

Hello!

There are three possible lengths.

We need to keep in mind that the total area cant exceed $60 ft^{2}$ , so, knowing that, we just need to find numbers that can be multiplied giving as result 60.

First combination:

$4ft(height)X15ft(width)=60 ft^{2}$

Second combination:

$5ft(height)X12ft(width)=60 ft^{2}$

Third combination:

$6ft(height)X10ft(width)=60 ft^{2}$

Have a nice day!
