ANSWER
As given in question
plant’s height = 37 centimeters
it grows at a rate of 0.004 centimeter per hour of sunlight
Andrea conducts a science experiment and observes that the height of a plant depends on the amount of sunlight it receives.
the number of hours of sunlight = s
Than the equation become in the form
f(s) = 0.004s + 37
this equation shows the height of the plant .
Hence proved
Answer:
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 62 - 2.08 = 59.92
The upper end of the interval is the sample mean added to M. So it is 62 + 2.08 = 64.08.
The 90% confidence interval for the mean score of all takers of this test is between 59.92 and 64.08. The lower end is 59.92, and the upper end is 64.08.
Answer:
6
Step-by-step explanation:
3x+6+5x+10=64
3x+5x+6+10=64
8x+16=64
8x=64-16
8x=48
divide both sides by 8
x=6
True? I dont know what you're trying to ask. if you're asking whether or not it's true, it is.
