Simplify 9 to the 2nd over 9 to the 7th.

1 answer:

7 0

Use the exponent rules
x^a/x^b =1/x^b-a

9^2/9^7 = 1 / 9^7-2 = 1/9^5
1 over 9 to the 5th = 59049
so it would be 1/59049
1 0ver 59049

Suppose a batch of metal shafts produced in a manufacturing company have a variance of 6.256.25 and a mean diameter of 206206 in

bearhunter [10]

Answer:

Step-by-step explanation:

mean diameter = 206

variance = 6.25

standard deviation = √ variance

σ = √ 6.25 = 2.5

sample size n = 90

z = deviation from mean / (σ / √n)

= 0.3 / (2.5/ √90)

= .3 / .2635

= 1.1385

P value from the table = (.87 - .5 ) x 2

= .37 x 2 .

or 74 % .

What is the solution to : 3(1/2 m - 3) =45

VladimirAG [237]

Answer:

$m=36$

Step-by-step explanation:

We can solve for this equation by isolating $m$ on one side. To do this, we can "reverse" the equation.

$3(\frac{1}{2}m - 3) = 45$

Let's divide both sides by 3.

$3(\frac{1}{2}m-3)\div3 = 45\div3\\\\\frac{1}{2}m - 3 = 15$

Add 3 to both sides:

$\frac{1}{2}m - 3 + 3 = 15 + 3\\\\\frac{1}{2}m = 18$

Multiply both sides by two (since $\frac{1}{2}\cdot2=1$ )

$\frac{1}{2}m \cdot 2 = 18 \cdot 2\\\\m = 36$

Hope this helped!
