Answer: C) 133

Step-by-step explanation:

The formula to find the sample size is given by :-

n=(\dfrac{z^*\cdot\sigma}{E})^2

, where z* = Critical z-value

\sigma = Population standard deviation for prior study.

E= Margin of error.

As per given , we have

\sigma=$35

E= 5

The critical z-value for 90% confidence level is 1.645.

Substitute al;l the value sin the above formula  , we get

n=(\dfrac{1.645\times 35}{5})^2

n=(\dfrac{57.575}{5})^2

n=(11.515)^2

n=132.595225\approx133

Hence, the minimum sample size needed is 133.

Thus , the correct answer is : C) 133

Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo
Keith_Richards [23]
Hi i'd be glad to help you with this equation. 

basically all we have to do is find (65%) of 455*. 

65% of 455* = 295.75 

Next. 

455 + 295.75 = 750.75 

So, to check my work I have 750.75 miles in total. 

I have already driven 455 miles of 750.75 miles. 

Using subtraction we subtract our distance from our total. 

750.75 - 455 = 295.75 

So, in total your answer to this problem is (295.75) 

Hope this helps. 
Have a great day!

How can you quickly determine the number of roots a polynomial will have by looking at the equation?
Goryan [66]
First, you need to get delta which is b squared minus 4ac. If delta is higher than cero, the polynomial has two solutions, if it is less, the polynomial has no real solutions and if it is the same, it has one solution.
Although that is only for second grade ecuations
