Rewrite using a single positive exponent

Korolek [52]

Answer:

9³

Step-by-step explanation:

We need to find the value of $\dfrac{9^5}{9^2}$ .

We know that,

$\dfrac{x^a}{x^b}=x^{a-b}$

Here, a = 5 and b = 2.

So,

$\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3$

So, the answer to the given expression is 9³.

A random sample of the amounts for 22 purchases was taken. The mean was $42.97, the standard deviation was $22.82, and the m

Illusion [34]

Answer: a) 84 and b ) 2084

Step-by-step explanation:

Given : Sample standard deviation : s= $22.82

(Population standard deviation is unknown ) , so we use t-test.

Critical value or the 95% confidence intervals : $t_{n-1}*=2.0$

Formula to find the sample size :

$n=(\dfrac{t^*\cdot s}{E})^2$

a) E = 5

$n=(\dfrac{(2)\cdot 22.82}{5})^2$

$n=(9.128)^2=83.320384\approx84$

i.e. Required sample size : n= 84

b) E = 1

$n=(\dfrac{(2)\cdot 22.82}{1})^2$

$n=(45.64)^2=2083.0096\approx2084$

i.e. Required sample size : n= 2084
