Answer:
I think it might be 13 or 14 I'm not completely sure though.
Step-by-step explanation:
The slope of your line CD is 4 because it goes up to 8/2 ( rise/run)
The volume will decrease.
If everything else remains the same then it will decrease. If other sides were increased proportionally then it would stay the same. It would increase if other sides were enlarged more than the length was shortened.
You can use integer’s absolute value in real-life situation
when you are in an event of describing the distance from something or to
something using the whole number. Integers are numbers that fractional
components are not present and usually include both positive and negative
numbers including zero while absolute value is the distance from a zero a
number has.
To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.
The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypotheis is a contradiction of the null hypothesis which is that the <span>average commute time to downtown is not 20 minutes</span>.
i.e. H0: μ = 20 and H1: μ ≠ 20.
The z-statistics is given by (sample mean - hypothesized mean) divided by (standard deviation divided by the square root of the sample size).
i.e.
Therefore, <span>The z-statistic is 3.32, so the null hypothesis should be rejected. Because the calculated value of z (3.32) is greater than the table value of z (1.96).
*The table value of z is the z (alpha / 2) of the significant level.</span>
