Answer: D.) Cultural knowledge
Step-by-step explanation:
16 2/3 minus 4 1/6 equals 12 1/2.
She has 12 1/2 hours to work left
<span>(35n^3 - 30n^2 + 25n) ÷ (-5n)
</span><span>= -5n(-7n^2 + 6n - 5) ÷ (-5n)
= </span>-7n^2 + 6n - 5
A suitable probability calculator will tell you that probabilty is about 25.9%.
_____
The normalcdf function on this calculator gives an area between a lower and upper limit. If the upper limit is more than about 8 standard deviations above the mean, the 10th decimal place is unaffected. Since the standard deviation here is about 5, we need to have an upper limit that is about 40 above the mean of about 30. We have chosen 80 as a nice round number and to give a little more margin.
Answer:
<h2> 0.027</h2>
Step-by-step explanation:
The number of groups of 5 boys that we can have from 7 boys is 7C5 = 21
The number of groups of 5 boys that we can have from 12 students is
12C5 = 792
then the probability = 21/792 = 0.026515151515
by the way you can calculate 12C5 and 7C5 using a calculator.
