Answer:
False
Step-by-step explanation:
Well it's True in a way, but they didn't simplify all the way. Correct simplification would be 1/3
<h2>y is 28.125 when x = 25</h2>
<em><u>Solution:</u></em>
Given that,
y is inversely proportional to the square root of x
Therefore,
----------- eqn 1
Where, c is constant of propotionality
y = 45 when x = 64
Substitute in eqn 1
What is y when x = 25?
Substitute x = 25 and c = 5.625 in eqn 1
Thus y is 28.125 when x = 25
Answer:
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Step-by-step explanation:
We are given the following in the question:
Mean storage capacity = 60 ampere-hour
95% confidence interval =
Thus, the correct answer based on the confidence interval is
Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %
Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah
Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.
Answer: There are 100 blue marbles.
Step-by-step explanation:
252 x 2/7 = 72
72 is the number of the red marbles.
(252-72) x 4/9 = 80
80 is the number of the green marbles.
252-72-80 = 100
There are 100 blue marbles.
