Answer:
Let hardcover book be x
Let paperback book be y
2x+3y=$118....Equation 1
3x+2y=$137.... Equation 2
Solve for x and y using simultaneous equation
Using elimination method
2x+3y=118......×3
3x+2y=137......×2
6x+9y=354
6x+4y=274
9y-4y=80
5y=80
y=80÷5=16
substituting y=16 into equation 1
2x+3(16)=118
2x+48=118
2x=70
x=70÷2=35
Therefore hardcover costs $35 each
paperback cover costs $16 each

Find the mean and the standard deviation of the data set {5, 8, 1, 2, 10}.
5 + 8 + 1 + 2 + 10 = 26 (divided by) 5 = 5.2
The mean and the standard deviation of the data set is 5.2 and 3.429.
What is Arithmetic Mean?The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.
We have,
Data: {5, 8, 1, 2, 10}.
So, the mean of data
= (5+ 8 + 1 + 2 +10)/ 5
= 5.2
Then, the Value of Deviations
-0.2, 2.8, -4.2, -3.2, 4.8
So, the variance is
= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5
= 11.76
And, Standard deviation is

Could someone please help me find the missing X? Thank you :))) only if you know.
Answer:
x = 18[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 9² = 27²
x² + 81 = 729 ( subtract 81 from both sides )
x² = 648 ( take the square root of both sides )
x = [tex]\sqrt{648}[/tex] = 18[tex]\sqrt{2}[/tex] ← exact value

The function f(x) = 34,000(1.05)* can be used to
determine Noah's cost of living in Houston over time.
What does the 1.05 represent?
A The cost of living will increase by approximately 1% each year
B The cost of living will decrease by approximately 1% each year
C The cost of living will increase by approximately 5% each year
D The cost of living will decrease by approximately 5% each year
9514 1404 393
Answer:
C The cost of living will increase by approximately 5% each year
Step-by-step explanation:
If we assume your function is ...
[tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]
Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.
Noah's cost of living is increasing about 5% per year.

A tablecloth is 82 inches long. What is the length in feet and inches?
Answer: 6 feet and 10 inches
Step-by-step explanation:
Each foot has 12 inches in it
You can either divide 82 by 12 or
1 foot: 12 inches
2 foot: 24 inches
3 foot: 36 inches
4 foot: 48 inches
5 foot: 60 inches
6 foot: 72 inches
7 foot: 84 inches
Since 7 foot is too much you can now take 6 feet (72 inches) and subtract it from 82
82-72=10
10 meaning 10 inches
6 feet and 10 inches
You may also divide but you will get a decimal like this:
6.83333333
Unit conversion is a way of converting some common units into another without changing their real value. The length of the table cloth is 6 ft 10 inches.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
In terms of measurement, one foot is 12 inches.
1 ft = 12 inches
Given that the table cloth is 82 inches long. Therefore, the length in feet and inches are,
Length = 82 inches
= 82 / 12 foot
= 6 10/12 foot
= 6 ft 10 inches
Hence, the length of the table cloth is 6 ft 10 inches.

Mr. Jennings is shopping for a car loan. He wants to buy a car that costs $18,000. He plans to pay $5,000 in cash and get a loan for the rest. If the annual interest rate on the loan is 5%, how much interest will he pay in the first year?
Answer:
$650
Step-by-step explanation:
Interest = amount of the loan x interest rate x time
Amount of the loan = price of the car - cash payment
$18,000 - $5,000 = $13,000
interest rate = 5%
time = 1 year
$13,000 x 0.05 x 1 = $650

The weights of newborn elephants are normally distributed with a mean of 225 pounds and a standard deviation of 45 pounds. Find the probability that a newborn elephant weighs more than 210 pounds.
Answer:
0.63043
Step-by-step explanation:
Given that :
Mean = 225
Standard deviation = 45
P(x > 210) : (x - mean) / standard deviation
P(x > 210) = (210 - 225) / 45
P(x > 210) = - 0.333
P(Z > - 0.333) = 0.63043 (Z probability calculator)
HELP PLEASE! What’s the domain and range?
Answer:
Domain → (-∞, -1)∪(-1, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Given function is,
[tex]\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}[/tex]
This function is not defined when the denominator is zero.
2x + 2 = 0
2x = -2
x = -1
Therefore, x = -1 is not in the domain of this function.
And the domain will be,
(-∞, -1)∪(-1, ∞)
For all values of x (except x = -1) we get some output values (value of [tex]\frac{f(x)}{g(x)}[/tex]).
Therefore, range of the function will be (-∞, ∞).
