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

Solve for C:<br> Spam: deiodhwidweiudjegydjwe

Maksim231197 [3]

Answer:

$C=\frac{5F-160}{9}$

Step-by-step explanation:

Let's solve for C.

$F=\frac{9C}{5}$

Step 1: Flip the equation.

$\frac{9}{5} C+32=F$

Step 2: Add $-32$ to both sides.

$\frac{9}{5} C+32+-32=F+-32$

$\frac{9}{5}C=F-32$

Step 3: Divide both sides by $\frac{9}{5}$ .

$\frac{\frac{9}{5}C}{\frac {9} {5}}=\frac{F-32}{\frac{9}{5} }$

$C=\frac{5F-160}{9}$

Answer:

$C=\frac{F-160}{9}$
