Ostrovityanka [42]

Answer:

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6.5%/100 = 0.065 per year,

then, solving our equation

I = 95000 × 0.065 × 20 = 123500

I = $ 123,500.00

The simple interest accumulated

on a principal of $ 95,000.00

at a rate of 6.5% per year

for 20 years is $ 123,500.00.

This means that the null hypothesis is $H_{0} = 4.3$ .

The organization thinks that, currently, the mean is higher.

That is, higher than 4.3. So

The alternate hypothesis is $H_{a} > 4.3$

Bumek [7]

Answer: 9x - 18

Step-by-step explanation:

Inverse is when you swap the x's and y's and solve for y

$\text{Given: }\quad y=\dfrac{1}{9}x+2\\\\\text{Swapped: }x=\dfrac{1}{9}y+2\\\\.\qquad \quad x-2=\dfrac{1}{9}y\\\\.\qquad 9(x-2)=y\\\\.\quad \large\boxed{9x-18=y}$
