5/1
Step-by-step explanation:
the first set of the numbers you divide by 2 to get the answer. To get the answer for the second set of numbers, you divide by 3 to get your answer
Answer:
see below for a graph
x = 4
Step-by-step explanation:
The perimeter is given by the formula ...
P = 2(L +W)
The area is given by the formula ...
A = LW
We want these two values to be equal. Using "y" for both perimeter and area, and substituting the given values for L and W, we have the equations ...
y = 2(4 +x)
y = 4x
The graph of these equations (below) shows the value of x is 4.
The constant term is the term that does not have a variable (a letter).
In this case 8 is your answer, for it does not have a variable attached to it.

You have the answer and need to work backwards using the equation given
A=1/2bh
A=130
b=26
Plug in these numbers to get
130=1/2(26)h
1/2(26)=13
130=13h
Divide both sides by 13
h=10 meters
Answer:
Probability that in a random sample of six cities, the sample mean would be more than 40 is 0.3372.
Step-by-step explanation:
We are given that the percent of births to mothers with less than a college education in all of the most populated cities in the U.S. has an average of 39.3 with a standard deviation of 4.1.
Assuming the data follows distribution. Also, a random sample of six cities is selected.
<em>Firstly, Let </em><em> = sample mean of six cities</em>
The z score probability distribution for sample mean is given by;
Z = ~ N(0,1)
where, = average percent of births = 39.3
= standard deviation = 4.1
n = sample of cities = 6
Probability that in a random sample of six cities, the sample mean would be more than 40 is given by = P( > 40)
P( > 40) = P( > ) = P(Z > 0.42) = 1 - P(Z 0.42)
= 1 - 0.66276 = 0.3372
Therefore, probability that the sample mean would be more than 40 is 0.3372.
