Answer:
54.5
Step-by-step explanation:
Answer:
(x - 6)(x + 4) = 0.
Step-by-step explanation:
With your case of x2 - 2x - 24, we have b1+b2 = -2 and b1b2 = 1*(-24) = -24. So the equation x2 - 2x - 24 = 0 becomes (x - 6)(x + 4) = 0.
I'm pretty sure the answer is: <u><em>h = 9</em></u>
<u><em></em></u>
<u><em>Reason:</em></u>
The question tells us that to complete the equation that represents the relationship between d and h, so for "d", its d = 1, for h, it is 9 per each "days"
from the hours.
Answer:
It is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.5 mg
Standard Deviation, σ = 0.1 mg
We are given that the distribution of percentage of nitrogen score is unknown.
Formula with sampling:
P( mean of the sample of 100 fertilizers less than 2 mg)
P(x < 2)
Calculation the value from standard normal z table, we have,
Thus, it is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
