If an object on earth weighs 42 lbs, what is its weight on the moon?
Bogdan [553]

Answer:

6.93 lbs.

Step-by-step explanation:

The weight on the moon is approximately 16.5% of what you would weigh on Earth. Using this information, we can say that 16.5% of 42 lbs would equal how much the object would weigh on the moon.

I prefer to convert percentages the decimal way, so let's do it that way. 16.5% is 0.165 as a decimal, so now all we have to do is multiply 0.165 by 42 (since we are saying 16.5% of 42 lbs), and we get 6.93 lbs.

Hope this helps! :)

A local pizza store knows the mean amount of time it takes them to deliver an order is 45 minutes after the order is placed. The
Bad White [126]

Answer:

We need to conduct a hypothesis in order to check if the true mean is different from 45(alternative hypothesis), and then the system of hypothesis would be:  

Null hypothesis:\mu =45  

Alternative hypothesis:\mu \neq 45  

Since we don't know the sample size we can't calculate the statistic and the only thing that we can do is create the sytem of hypothesis.

Step-by-step explanation:

Data given and notation  

\bar X=48 represent the sample mean    

s=10 represent the sample standard deviation

n sample size  

\mu_o =45 represent the value that we want to test  

\alpha=0.05 represent the significance level for the hypothesis test.  

z would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

System of hypothesis

We need to conduct a hypothesis in order to check if the true mean is different from 45(alternative hypothesis), and then the system of hypothesis would be:  

Null hypothesis:\mu =45  

Alternative hypothesis:\mu \neq 45  

Since we don't know the sample size we can't calculate the statistic and the only thing that we can do is create the sytem of hypothesis.
