You stick the number of x into the function to produce the answer so
x=-8, y=-4
x=-4, y=-3
x=0, y=-2
x=4,y=-1
x=8,y=0
It is proportional because all the points if put in fraction form equals 1/5. For 1 plant, he has 5 roses, and for 2 plants, he has 10 roses. 2/10=1/5. 3/15=1/5. 4/20=1/5. They all have the proportions of 1 plant per every 5 roses
Positive 28 because it’s above the ocean so it’s in the positive see it make sense so if it was below sea level it would be negitive
Answer:
We want to construct a confidence interval at 99% of confidence, so then the significance level would be
and the value of
. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
And if we find the critical value in the normal standard distribution or excel and we got:

And we can use the following excel code:
"=NORM.INV(0.005,0,1)"
Step-by-step explanation:
For this case we have the following info given:
