The most appropriate interpretation for the slope of the data given is the height of water in the pool increases by 2 inches per minute. Option (1) is correct.
The slope of a line, also known as its gradient, is the value of the steepness or direction of a line in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.
Given that
Time Height
2 8
4 12
6 16
8 20
10 24
The slope of the line = 2
A line's slope is also known as its gradient or rate of change.
The slope can be positive or negative; positive slope values indicate an increase in x as y increases and vice versa.
A negative slope indicates that one variable decreases as the other increases.
Because the slope value given here is positive, we can conclude that the height of the water increases over time.
As a result, the height of the water rises by 2 inches per minute.

80 percent increased by 30 percent is what percent of 80
30% of 80% is 24% and the resulted percent will be 104% when 80% is increased by 30%.
What is fraction?A fraction is a portion of a whole or, more broadly, any number of equal pieces. In ordinary English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. A fraction is a portion of a larger total. The number is stated in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complicated fraction contains a fraction in either the numerator or the denominator.
Here,
30% of 80%
=30*100(80*100)*100
=30*80/100
=24%
When 80% is increased by 30%, the resultant percent is 104% because 30% of 80% is equal to 24%.

The two given fractions are -
9/8 and 11/12
We have to find out the Least Common Denominator (LCD) of 9/8 and 11/12.
Firstly, we have to check if we can simplify the two given fractions. In this case, we have 9/8 and 11/12 which cannot be simplified further.
Now, we have to multiply the denominators with natural numbers until they there is a first common number in the denominators of the two given fractions.
Multiplying 8 with 2 gives 16. However, there 16 is not a multiple of 12,
Multiplying 8 with 3 gives 24. 12 when multiplied with 2 also gives 24.

Find three consecutive even integers such that the sum of the least integer and the middle integer is 24 more than the greatest integer.
Answer:
26, 28, 30
Step-by-step explanation:
there is a difference of 2 between consecutive even integers
let the integers be n , n + 2 , n + 4 , then
n + n+ 2 = n + 4 + 24
2n + 2 = n + 28 ( subtract n from both sides )
n + 2 = 28 ( subtract 2 from both sides )
n = 26
n + 2 = 26 + 2 = 28
n + 4 = 26 + 4 = 30
the 3 consecutive even integers are 26 , 28 , 30
Find the area of a rectangle with dimensions

The area of the rectangle is 11/96 in²
How to determine the area of the rectangle?In this question, we have the following parameters
Dimensions of rectangular area: 11/12 in x 1/8 in.
The area of a rectangle is the products of its dimensions
i.e. Area = products of dimensions
This implies that
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
Area = 11/12 in x 1/8 in
Evaluate
Area = 11/96 in²

The value of the residual is 2.
We are given a fitted linear regression equation. The equation is given below.
ŷ = 6 - 2x
The x-value for the data points is 3, and the corresponding y-value is 2. We have to find the value of the residual.
We will substitute the given values in the equation of the regression line.
ŷ = 6 - 2x
ŷ = 6 - 2(3)
ŷ = 6 - 6

If avocados costs $2.99per pound, Nina will be paying $1.495
How to solve for the amount Nina would payThe information given in the problem shows that
avocado's have their price in pounds hence we convert the quantity given to pounds
1 pound = 16 ounces
? = 8 ounces
cross multiplying
8 * 1 = ? * 16
? = 8 / 16
? = 1/2
hence 8 ounces is 0.5 pounds
Then the cost of 0.5 pounds of avocados will be solved for
1 pounds = $2.99
0.5 pounds = ?

The ordered pairs that are solutions of the inequality are of the form:
(x, y > -3.5*x - 13)
Which ordered pairs are solutions of the inequality?
Here we have the inequality:
7x + 2y > -26
The solutions of this are the pairs (x, y) that, when replaced on the inequality, make it true.
If we isolate y on the inequality we get:
7x + 2y > -26
2y > - 26 - 7x
y > (-26 - 7x)/2
y > -3.5*x - 13
Then the ordered pairs are of the form:
(x, y > -3.5*x - 13)
For example, suppose that we fix the value of x in 0, then:
y > -3.5*0 - 13
y > -13

From the chart, estimate (roughly) the number of transistors per IC in 2016. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040?
Please explain
The estimates for the number of transistors per IC, using an exponential function, are given as follows:
2016: 16,777,216,000.2040: 6.87 x 10¹³.What is the format of an exponential function?An exponential function has the general format presented as follows:
[tex]y = ab^\frac{x}{n}[/tex]
In which the parameters of the function are listed as follows:
a is the initial value of the function.b is the rate of change of the function.n is the period relative to the rate of change.By Moore's Law, the number of transistors per IC doubles every two years, hence the values of parameters b and n are both two, that is:
b = 2, n = 2.
We take 1972 as the reference year, when the amount was of 4000 transistors per IC, hence the value of parameter a is given as follows:
a = 4000.
Thus the equation is:
[tex]A(t) = 4000(2)^{\frac{t}{2}}[/tex]
Giving the number of transistors per IC in t years after the reference year of 1972.
2016 was 44 years after 1972, hence the estimate for the amount of transistors by IC was of:
[tex]A(44) = 4000(2)^{\frac{44}{2}} = 16,777,216,000[/tex]
2040 will be 68 years after 1972, hence the estimate for the amount of transistors by IC is of:
[tex]A(68) = 4000(2)^{\frac{68}{2}} = 6.87 \times 10^{13}[/tex]
