Answer:
There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).
Step-by-step explanation:
We have to perform an hypothesis test on the mean.
The null and alternative hypothesis are:

The significance level is
.
The test statistic t can be calculated as:

The degrees of freedom are:

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.
This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.
There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.
x = 3/2
Step-by-step explanation:
Given equation is:

As we have to solve for x, x will be isolated on one side of the equation
So,
<u>1. Addition property of equality </u>
4x will be added on both sides

<u>2. Division property of Equality</u>
Dividing both sides by 6

Hence,
x = 3/2

Answer:
distance = rate x time
3 and 1/5 = 3.2 and 3 and 3/5 = 3.6
distance = 3.2 x 4.5 = 14.4
14.4 = 3.6 x T
T = 14.4 / 3.6 = 4 <--- Pedro's time
