Answer:


Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is


Answer:
The answer is y= x -1.
Step-by-step explanation:
here, given that; the slope is 1 and y intercept is 1. so, the formula of equation of a st. line in slope intercept form is y= mx+ c.
so, y= 1×x-1 (putting value of slope as one and y intercept as -1).
therefore, the answer is y= x-1....answer.

Answer:
x=21.
Step-by-step explanation:
First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
Since 7 is greater than 5, the 9 gets rounded. It would be 12.0.
&4 - $2= $2 You have to round the numbers to the closest one right.
