Gemiola [76]

Answer:

For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:

Null hypothesis: \mu =1.7

Alternative hypothesis \mu \neq 1.7[/tx]And the best system of hypothesis are:3. This two-sided test:
H0: μ = 1.7 mm
H1: μ ≠ 1.7 mmStep-by-step explanation:For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7.

An equation that involves a multiplication addition, contains a variable, and has a solution of 8.
yulyashka [42]
A variable is an unknown like x so 

first we start with 
x=8
then we subtract (because you must add to reverse subtraction)
x-2=8-2
x-2=6
then we divide ( because you must multiply to reverse division)
(x-2)/3=6/3
(x-2)/3=2

find x

You just bought a new laptop and paid an initial payment of $150.00. You will make 12 payments of $69.50. How much will the comp
Flauer [41]

Using proportions, it is found that the computer will cost $1,043.04.

<h3>What is a proportion?</h3>

A proportion is a fraction of total amount.

In this problem, the total amount is composed by:

  • An initial payment of $150.
  • 12 payments of $69.50.
  • 6% sales tax, which means that the price is increased by 6%, that is, the previous amount is multiplied by 1.06.

Hence, the cost is given by:

C = 1.06 x (150 + 12 x 69.50) = 1043.04.

The computer will cost $1,043.04.
