A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Anand is traveling by car a long distance. He has 10 gallons of gas in his automobile right now. His automobile burns through 2 gallons of gas per hour while he is on the road.

Then the equation will be

y = 10 - 2t

Where t is the number of hours and y represents the fuel left in the tank.

The amount of fuel left after 2 hours will be

y = 10 - 2 x 2

Division is a simple operation in which a number is divided.  1.168 ÷ 8= 0.146, 2.246÷12= 0.1871, 3.4328÷4=0.8582, 4.729÷9=0.5254 and 5.8415÷5​​​​=1.168.

Division is a simple operation in which a number is divided.

Division lets us separate a number of objects into equal-size groups.

Division has 3 important parts dividend, divisor, remainder and quotient.

1.168 ÷ 8= 0.146

(Because 0.146*8=1.168)

2.246÷12= 0.1871

(Because 12*0.1871=2.246)

3.4328÷4=0.8582

(Because 4*0.8582=3.4328)

4.729÷9=0.5254

(Because 9*0.5254=4.729)

5.8415÷5​​​​=1.168.

(Because 5*1.168=5.8415)

Therefore 1.168 ÷ 8= 0.146, 2.246÷12= 0.1871, 3.4328÷4=0.8582, 4.729÷9=0.5254 and 5.8415÷5​​​​=1.168.

Ths meaning of the slope based on the information is that the model predicts that cereals will have approximately 26 more milligrams of potassium for every additional gram of fiber.

It should be noted that the analysis of the amount of fiber (in grams) and the potassium content(in milligrams) in servings of 77 breakfast cereals produced the regression model.

The model used was:

Potassium = 35 + 26 Fiber

Therefore, the meaning of the slope based on the information is that the model predicts that cereals will have approximately 26 more milligrams of potassium for every additional gram of fiber.

Step-by-step explanation:

Tristan's forecast for income next year is $3,876.

The forecast income can be determined using the mathematical operation of multiplication.

First, the total number of hours worked next year is determined as 204.  This is a product of 17 weeks and a 12-hour week.

Lastly, the above product multiplies the hourly pay rate at $9.50 by two semesters, to determine the expected income for next year.

The average hours of work by Tristan per week = 12 hours

Hourly pay rate = $9.50

The total number of weeks to work = 17 weeks

The total number of hours to be worked = 204 hours (17 x 12)

Expected earnings for each semester = $1,938 ($9.50 x 204)

Expected earnings for two semester = $3,876 ($1,938 x 2)

Thus, Tristan should expect to earn $3,876 for next year.

The lenght of the side b is 5 units

According to the given information the triangle is an right angled triangle with sides a,b, c where a and b are the two legs of the triangle and c is the hypotenuse the measurments of the side a and c are given 12 and 13 respectively . For finding the value of  b we need to use pythagoras theorem that is (Hypotenuse)² = (base)² + (height)²

Here we are going to use the same theorem for finding the value of the side b

According to the question:

hypotenuse = c = 13 units

height = a = 12 units

base = b = ?

As per  the theorem : hypotenuse ² = base ² + height²

∴ (13)² = b² + (12)²

=> 169 = b² + 144

=> b² = 169 - 144

=> b² = 25

=>b = √√25 = ±5

b = 5 [∵ lenght cannot be negative ]

Based on the information provided, we have:

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.

Given the following functions:

f(x) = 5x

g(x) = x - 3.

Next, we would determine the value of composite function f(g(x)) as follows:

f(g(x)) = f(x - 3)

f(g(x)) = 5(x - 3)

f(g(x)) = 5x - 15.

Also, we would determine the value of composite function g(f(x)) as follows:

g(f(x)) = g(5x)

g(f(x)) = (5x) - 3

g(f(x)) = 5x - 3.

19. If I go swimming, then my skin will get wet.

20. If a number is divisible by 6, then it is divisible by 3.

21. If it is a Tuesday, then the tickets are half-priced.

The phrase "if...then" is used to denote a conditional statement. If p and q are the two statements, then p and q can be written under several conditions, such as;

Given the statements:

p: My skin will get wet

q: if I go swimming

Here, q is necessary for p.

Hence, the condition statement is "If I go swimming, then my skin will get wet."

p: a number is divisible by 6

q: a number is divisible by 3

Here, p implies q.

Hence, the condition statement is "If a number is divisible by 6, then it is divisible by 3."

p: movie tickets are half-price

q: it is a Tuesday

Here, q is necessary for p.

Hence, the conditional statement is "If it is a Tuesday, then the tickets are half-priced."

Assuming an hypergeometric distribution, the probability that both are red is equal to 33.99%

In an hypergeometric distribution, these three (3) conditions listed below must hold:

In Mathematics, probability from an hypergeometric distribution can be calculated by using this formula:

[tex]p(X = x) = \frac{^MC_x \;^{N-M}C_{n-x}}{^NC_n}[/tex]

N = 12 + 31 = 43

n = 2

M = 12

N - M = 43 - 12 = 31

Substituting the parameters into the formula, we have;

P (X = 2) = (¹²C₂ × ³¹C₂)/⁴³C₂

P (X = 2) = 30,690/903

If we want the two ratios to be equivalent, then we need to use x = 15 and y = 33.

Let's say that we have a simple ratio between two amounts, it is A:B

If we multiply both of these amounts by the same scalar, k, we will get:

k*A and k*B

And the ratio between the new amounts k*A: k*B is equivalent to the first ratio, A:B

So we will use this to solve the problem, here we have two ratios:

5:2:11 = x:6:y

Note that in the first ratio the first value is 2, and in the second case it is 6 so let's find the value of k such that:

2*k = 6

k = 6/2 = 3

Then if we multiply the correspondent values in the first ratio by 3, we will get:

x = 5*3 = 15

y = 11*3 = 33

Then we can see that the ratios:

5:2:11 and 15:6:33 are equivalent.

We can say that 8 inches = 24 feet. This is our answer.

The correct answer is an option (E) The statement is true. To determine how much a value increased by, the relative change should be computed. In this case, the relative change is 40%

In this question, we have been given a statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.'

We need to check whether given statement is true or false.

The bank raised its interest rate on savings accounts from 2% to 2.8%

We find the percent increase.

Here the absolute increase is: |2.8 - 2| = 0.8

The relative increase is: absolute increase / original value

= 0.8 / 2

= 0.4

The percent increase is: relative increase × 100

= 0.4 × 100

= 40%

Therefore, given statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.' is True.
