The mean number of individuals per sample who do not exercise regularly = 7

According to the survey 58% of the Americans does not exercise.

Hence probability of not exercising, p = 58/100 = 0.58

Define a random variable X denoting the number of people who does not exercise.

Then X follows the binomial distribution.

If p denotes the probability of success and if n is the sample size or number of trials, then

P(X = x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ gives the probability of the random variable X.

Here, the sample size, n = 12

For a binomial distribution, mean, μ = np

Therefore,  mean number of individuals per sample who do not exercise regularly = np

               = 12 x 0.58

               = 6.96

               ≈ 7

The slope is 1.

Explanation:

The equation of a line is written in "slope-intercept form as

Julie received an amount of $134.4 when she cashed her paycheck.

Let x be the amount of the paycheck.

She gave her brother ten dollars.

She then paid $30 for the car's petrol.

So she departed with an amount equal to x-40.

She now spent half of the remaining accounts on a new camping tent.

Spent camping = (x - 40)/2

Remaining = x - 40 - (x - 40)/2

She paid $29.45 for a pair of running shoes.

Therefore, remaining =  x - 40 - (x - 40)/2 - 29.45

As per the question, she had $17.75 remaining.

So x - 40 - (x - 40)/2 - 29.45 = 17.75

Rearrange the terms and solve for x,

(x - 40)/2 = 47.2

x - 40 = 94.4

x = 134.4

Therefore, she received an amount of $134.4 when she cashed her paycheck.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula,

y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula t.

Using a straight line's slope and the location of its y-axis intersection, the slope intercept equation can be used to determine the general equation of the line. Y = mx + b is the equation in slope intercept form.

The slope-intercept form is provided as y = mx + b, where m is the line's slope and b is the y-intercept. Using this form, we may determine the slope of a line. Here's an illustration. The slope of the line 6x - 3y = 5 should be determined. To convert this into the slope-intercept form, let's solve this for 'y'. The result is y = 2x – (5/3). We calculate the slope to be m = 2 by comparing this to the slope-intercept formula, y = mx + b.

A)  The probability that at least one of the two students will be in class on a given day is; 0.92

B)  If at least one of the two students is in class on a given day, the probability that a is in class that day is; 0.8696

In probability theory, the occurrence of the events may depend on its relative events which are called dependent events while the events not dependent on their relative events are referred to as independent events. For dependent events, if conditional probabilities are required , we will make use of the Baye's Theorem and the total probability theorem sometimes.

We are given;

Probability that student A attends class = 80% = 0.8

Probability that student B attends class = 60% = 0.6

A) The probability that at least one of the two students will be in class on a given day is;

P = 1 - Probability that that neither show up to class on any given day.

P(A ∪ B) = 1 - P(A∼ ∩ B∼)

Where  P(A∼ ∩ B∼) = (1 - 0.8) × (1 - 0.6)

P(A∼ ∩ B∼) = 0.08

Thus;

P(A ∪ B) = 1 - 0.08

P(A ∪ B) = 0.92

B) We want to find the probability that student A was in the class given that at least one of them was in the class.

This is obviously a case of conditional probability which will give us the formula;

P(A|A ∪ B) = P(A ∩ (A ∪ B))/P(A ∪ B)

= P(A)/P(A ∪ B)

= 0.8/0.92

Considering the average rate of change of the function, the matched pairs are given as follows:

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given according to the following rule:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For the interval given by item 1, between -1 and 2, we have that:

Hence the rate is:

r = (-17 - (-2))/(2 - (-1)) = -15/3 = -5.

Meaning that 1 matches with a.

For the interval given by item 2, between -1 and 0, we have that:

Hence the rate is:

r = (3 - (-2))/(0 - (-1)) = 5/1 = 4.

Meaning that 2 matches with b.

For the interval given by item 3, between 1 and 2, we have that:

Hence the rate is:

r = (-17 - (-2))/(2 - 1) = -15/1 = -15.

Meaning that 3 matches with c.

For the interval given by item 4, between -2 and 0, we have that:

Hence the rate is:

r = (3 - (-17))/(0 - (-2)) = 20/2 = 10.

Meaning that 4 matches with d.

The equation using slope - intercept from the given point.

(a) y=8x-46

(b) 8x-y=46

what is slope ?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

Step-by-step explanation:

-y=-8x+4

y=8x+4

We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.

Substitute (6,2)

2=8(6)+b

2=48+b

b=-46

The equation of the line in point-slope form was y = -1/5x - 2.8

The equation of a line takes the form:

y = mx + b

m is the rate of change

b is the y-intercept

We need to find the y-intercept because we have the rate of change and y and x values:

-6.5 = 2/3(-3.5) + b

-6.5 = -2.33 + b

b = -6.5 + 2.33

b = -4.17

The equation is:

y = 2/3x - 4.17

The equation for the second line takes the same form. So the y-intercept should be found first:
