inysia [295]

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

5) Find the distance between -9 and 12 on a number line.​
kati45 [8]

Answer: Hope this helps!!!

Step-by-step explanation:Absolute Value: You need to find how far away both numbers are from zero, then add these values together to see how far apart these numbers. The absolute value of nine, |-9| is 9, and |12| is 12. This means that the nine is nine spots away from zero, and twelve is twelve spots from zero. This means that the numbers are 20 units from each other.

Distance -9 is from 12 You need to find how much of an increase from nine you need to reach the twelve. So -9 + ? = 12. What number can you add to equal twelve? You can add 20 to make the equation true. (? = 20) The distance from -9 to 12 is a positive 20.

Distance from 12 to -9 This is similar to the previous example. What number can you insert to make the 12 equal the negative nine? 12 - ? = -9. The number would be -20, which means that 12 is 20 spots away from the negative nine, as it took at negative twenty to get us to the negative nine.
