17297280 ways can the sites for the new stores be selected. This can be solved using the concept of probability.
What is probability?The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Given that,
14 different sites on which to locate 7 stores
For store 1, it can be placed on 14 sites.
Store 2 can be placed on 13 sites (since store 1 is already on site 1).
Store 3 can be placed on 12 sites and
so on until store 7 which has 8 sites.
Therefore the number of ways is:
C = 14 × 13 × 12 × 11 × 10 × 9 × 8
C = 17297280 ways

one person drives 70,000 miles in a car that averages 30 miles per gallon (mpg). how much gasoline are they using?
The person is using approximately 2,333.333 gallons of gasoline.
The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.
To calculate the amount of gasoline used, you can use the formula:
gasoline used = total miles driven / mpg
Where total miles driven is 70,000 miles and mpg is 30.
Plugging these values into the formula, we get:
Gasoline used = 70,000 miles / 30 mpg = 2,333.333 gallons
So the person is using approximately 2,333.333 gallons of gasoline.

Find an equation for a line passing through (10,10) that is perpendicular to the line with equation 5x+8y=-9. Write your equation in
The equation of a line passing through (10,10) that is perpendicular to the line with equation 5x + 8y = -9 is y - 10 = (8/5)(x - 10) or y = (8/5)x - 6.
Get the slope of the line 5x + 8y = -9 by rewriting it in slope-intercept form. Subtract 5x from both sides and divide by 8.
y = (-5/8)x - (9/8)
The slope of this line is -5/8. The negative reciprocal of -5/8 is 8/5. Therefore, the slope of the line that is perpendicular to 5x + 8y = -9 is 8/5.
Using point-slope form, determine the equation of the line.
y - y₁ = m(x - x₁)
y - 10 = (8/5)(x - 10)

Jerome has $3,000 to invest in an account that yields 2.1% annual interest which is compounded quarterly. If he leaves the money untouched in the account for 4 years, how much money will he have?
Jerome will have $3261.93 after 4 years
How to calculate how much money Jerome will have?
The formula for compound interest is A = P(1 + r/n)^(nt)
where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for.
In this case, P = $3,000, n = 3, r = 2.1% = 0.021, t = 4 years. Thus:
A = P(1 + r/n)^(nt)
A = 3000(1 + 0.021/3)^(3×4)
A = 3000(1 + 0.021/3)^(12)

The minimum number of hours you will have cruise control on is 1.83 hour(s) and the maximum is 2.83 hour(s).
To find the minimum and maximum numbers of hours you will have cruise control on, you need to calculate the distance you will travel with cruise control on and divide it by your speed.
The minimum distance you will travel with cruise control on is
140 miles - 30 miles = 110 miles.
The maximum distance you will travel with cruise control on is
140 miles + 30 miles = 170 miles.
To convert these distances into hours, you will divide them by your speed of 60 miles per hour.
Minimum hours: 110 miles / 60 mph = 1.83 hours
Maximum hours: 170 miles / 60 mph = 2.83 hours

What is the equation of the line in slope-intercept form that passes through point (4, 5) and is parallel to the line y = −2x − 2?
Answer:
y = -2x + 13
Step-by-step explanation:
In order to write an equation of the line in slope-intercept form, we first have to look at the equation:
y = mx + b
We know that m represents slope, and b represents the y-intecept, in other words, what y is equal to when x is equal to zero.
We already have y and x, (4,5), and the slope of the line, since the two lines are parellel, they share the same slope. So now, we have to pulg those values into the equation and solve for b:
(4,5)
y = 5
x = 4
m = -2
y = mx + b
(5) = (-2)(4) + b
5 = -8 + b
13 = b
So, equation of the line in slope-intercept form that passes through point (4, 5), is y = -2x + 13

The correct option is Option A: (5h^2)^3 + (3k)^3
The total number of cubic units that the cube totally occupies is the definition of a cube's volume. A cube is a solid three-dimensional object with six square faces. Volume is simply the total amount of space an object takes up. A thing with a bigger volume would take up more room.
Total Volume = V₁ + V₂
V₁ = Volume of Cube 1
V₂ = Volume of Cube 2
Volume of Cube = (Side Length)³
V₁ = (5h²)³
