Answer:
The significance level is
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:

So we reject the null hypothesis is 
Step-by-step explanation:
For this case we define the random variable X as the number of entry-level swimmers and we are interested about the true population mean for this variable . On specific we want to test this:
Null hypothesis: 
Alternative hypothesis: 
And the statistic is given by:

The significance level is
and since we are conducting a right tailed test we need to find a critical value who accumulate 0.01 of the area in the right of the normal standard distribution and we got:

So we reject the null hypothesis is 
Answer: 2^3 * 5^2.
Exclamation: Since 2 is multiplied out three times, you have 2 to the third power. Same goes for the five- since it’s there twice, that’s 5 to the second power. That brings us to 2^3 * 5^2
Answer:
it's just a turned reflection
Step-by-step explanation:
(x-8) (x+5) are the factors for the expression as -8 and 5 multiply to make -40 and add to make -3.
60x0.8=48
60-48=12
12/0.4=30
30-12=18
18/0.3=60
60-18=42
42/0.75=56
