<u><em>Answer:</em></u>It represent the tens of the number, therefore, it's unit value is 30
<u><em>Explanation:</em></u>The place value chart is added in the attached image.
<u>Checking this chart, we would find that:</u>
first digit from the right is the units of the number
second digit from the right is the tens of the number
third digit from the right is the hundreds of the number
Comparing this with the nuber given, we would find that the 3 is in the tens position. Therefore, it unit value is 30.
<u>Another way to answer this is by breaking the number given as follows:</u>
432 = 400 + 30 + 2
We can note that the unit value of the 3 is 30

Answer:
There is sufficient evidence to support the claim that the mean temperature is different from 42 deg
Step-by-step explanation:
From the given information, we are being told that:
The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, μ, of 42°F
i. e mean μ = 42
The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.
Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
From above;
The null and the alternative hypothesis can be computed as:
Here , the hypothesis test of the claim is the alternative hypothesis.
The conclusion based on the decision rule: is to reject the null hypothesis
∴
The conclusion in non technical terms is that :
There is sufficient evidence to support the claim that the mean temperature is different from 42 deg

Answer: $19.55
Step-by-step explanation:
- 2.75 * 5 = 13.75.
- 2.90 * 2 = 5.80
- 13.75 + 5.80 = 19.55
If Erica earned a total of $15450 last year from both the jobs then he earns $2840 from college if she earned 1250 more than four times the amount from college from store.
Given Total amount earned=$15450,Amount earned from store is 1250 more than 4 times earned from college.
Amount from store forms an equation.
let the amount earned from college is x.
According to question:
Amount earned from store=4x+1250
Amount earned from college=x
Total amount earned=4x+1250+x
5x+1250=15450
5x=15450-1250
5x=14200
x=14200/5
x=2840
Put the value of x in 4x+1250 to get amount earned from store=4(2840)+1250=$12610.
Hence the amount earned by Erica from college is $2840.
