Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>Distribute this to get:</u>
- a(b + c) = ab + ac
- 5(2 + 7) = 5(2) + 5(7)
Correct choice is D
Answer:
700$
Step-by-step explanation:
If all the seats cost tge same and each member takes a seat each game so we can say:
7×4=28
5×4=20
28x+20x=1200
48x=1200
x=25(seat price)
28×25=700
20×25=500
Substitute the variable for value we're given.
-9(2) - 7
-18 - 7 = -25
So, -25 is the answer.
The instantaneous rate of change is simply equivalent to
the first derivative of the equation or function. We are given the equation of
Surface Area (A) with respect to side (x):
A = 6 x^2
Taking the first derivative of the equation:
dA = 12 x dx
dA / dx = 12 x
Now the term dA / dx is the instantaneous rate of change
in the surface area with respect to the side length. To get the rate of change
when the side x = a, simply plug this in into the equation:
rate of change = dA / dx = 12 x
so when x = a:
<span>rate of change = 12 a</span>
Answer:
a) 
And using the normal distribution table or excel we got:
b) 
And we can use the normal standard table or excel in order to find the probability and we got:
Step-by-step explanation:
For this case we know that the random variable of interest is normally distributed with the following parameters:
Part a
We want to find this probability:
And we can use the z score formula given by:
Replacing we got:
And using the normal distribution table or excel we got:
Part b
We select a random sample of size n = 16 and we try to find this probability:
And we can use the z score formula given by:
And replacing we got:
And we can use the normal standard table or excel in order to find the probability and we got:
