Answer:
25 and 12
Step-by-step explanation:
1) x+y=37
x-y=13 or x=13+y
Put x=13+y into equation 1:
13+y+y=37
y+y=24
y=12
x=25

How much space is taken up by a book that is 12 inches long, 10 inches wide, and
1 inch tall?
Answer: It takes up 120 inches^3
Step-by-step explanation:
Write this equation in standard form: (4, -1) m = 3
Standard form looks like this: Ax + By = C.
y - (-1) = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 12 - 1
y = 3x + 13
Move 13 to left side and y to right side.
-13 = 3x - y
Done!
6. A recent Gallop poll showed Trump's approval rating 40% with a margin or error of 3%.
a) Find the confidence interval,
c) Does the confidence interval support that more than 50% of Americans approve of
Trump? Why or why not?
Answer:
Explained below.
Step-by-step explanation:
The (1 - α)% confidence interval for the population proportion is:
[tex]CI=\hat p\pm MOE[/tex]
Given:
[tex]\hat p=0.40\\MOE=0.03[/tex]
(a)
Compute the confidence interval as follows:
[tex]CI=\hat p\pm MOE[/tex]
[tex]=0.40\pm0.03\\\\=(0.37, 0.43)[/tex]
(b)
Since the confidence interval consists of values less than 50%, it implies that there is not enough evidence to suggest that more than 50% of Americans approve of Trump.

The first term of a geometric series is -3, the common ratio is 6, and the sum of the series is -4,665 Using a table of values, how many terms are in this geometric series
Answer:
There are 5 terms in the series.
Step-by-step explanation:
[tex]S=a\frac{1-r^{n} }{1-r}\\a=-3\\r=6\\-4665=-3\frac{1-6^{n} }{1-6}\\1555=\frac{1-6^{n} }{-5}\\\-7775=1-6^{n}\\6^{n}=7776\\[/tex]

How many 5-digit numbers are there in which three of the digits are 6, or two of
the digits are 9 ?
Answer:
The value is [tex]Z = 80[/tex]
Step-by-step explanation:
From the question we are told that
The total number of digit is n = 5
The total possible number of 6 is k = 3
The total possible number of 9 is a = 2
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 3 of the digit are 6 is mathematically represented as
[tex]N = ^ nP_k[/tex]
Here P stands for permutation hence we are going to be making use of the permutation function in our calculators
[tex]N = ^ 5P_3[/tex]
=> [tex]N = 60[/tex]
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 2 of the digit are 9 is mathematically represented as
[tex]M = ^ nP_a[/tex]
[tex]M = ^ 5P_2[/tex]
=> [tex]M = 20[/tex]
Generally the number of 5-digit numbers there are in which three of the digits are 6, or two of the digits are 9 is mathematically represented as
[tex]Z = M + N[/tex]
=> [tex]Z = 60 + 20[/tex]
=> [tex]Z = 80[/tex]

find the height of a with a cone with a diameter of 22 m whose volume is 113 m3.
Answer:
h=0.89
Step-by-step explanation:
Given
Diameter=22m
so radius=11m
Volume=113m^3
Solution
1/3πr^2h=113
1/3×3.14×11×11h=113
h=113×3/3.14×11×11
h=0.89
So the value of h is 0.89
Answer:
it's 3 m

The regular price of a laptop computer is $914.00. This week, it is on sale for $886.00 of
What is the sale price of the computer?
Answer:
3.1%
Step-by-step explanation:
Subtract.
914 - 886 = 28
Divide by the original price.
28/914 = 0.0306345...
Multiply by 100%.
0.0306345... * 100% = 3.06345%
Round if needed.
3.06345% -> 3.1%
Best of Luck!

A home improvement store advertises 60 square feet of flooring for $287.00 including an $80.00 installation fee. How much does each square foot of flooring cost?
50 POINTS *GIVEING BRAINLIEST*
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp) ( answer)
Answer:
60 square feet for 287 = 287/60 = 4.78 per square foot
so ur equation would be : y = 4.78x + 80
