Answer:
3,800 = 38 * 100
Step-by-step explanation:
3.8 * 100
= 380
38 * 100
= 3,800
There is no missing exponent or factor, it's just 3.8 needs to be multiplied by 10.
20 + (0.4 × 15) + 12 + (0.4 × 10) = 20 + 6 + 12 + 4 = 42
20 + 15 + 12 + 10 = 57
57 - 42 = 15
15 ÷ 57 × 100 = 1500 ÷ 57 = 26.3
Ans = $42.00, 26% off ...
Answer:
Step-by-step explanation:
We are given the claim.
Claim: The mean weight of male aerobics instructors in a certain city is more than 182 lbs.
Population mean = 182 lbs
The null hypothesis will state that the sample mean is less than or equal to the population mean 182 lbs.
The alternate hypothesis will state that mean weight of male aerobics instructors in a certain city is more than 182 lbs.

The absolute value equation written by Edwin according to his intention in the task content is; |x -3.9| = 0.3 and The values that are 0.3unuts from 3.9 are; 4.2 and 3.6.
<h3>What absolute value equation can be written by Edwin to find the numbers which are 0.3 units away from 3.9 on the number line?</h3>
Since the numbers in discuss are required to be 0.3 units from 3.9, it follows that one number is greater while the other is less than 3.9 and hence the required absolute value equation is;
|x -3.9| = 0.3. which can be solved as;
x-3.9 = 0.3; x =4.2.
Or
x -3.9 = -0.3; x = 3.6.
