Subtracting the maximum sodium intake from the intake of the cereal bar, you can eat amounts of sodium less than 2,175 mg of sodium the rest of the day.

From the text, the intake has to be less than 2300 mg. From the table, each cereal bar has 125 mg of sodium.

You eat one cereal bar, hence:

2300 - 125 = 2,175.

You can eat amounts of sodium less than 2,175 mg of sodium the rest of the day.

AB = 15, AC   = 14, BC = 8  

PQ = 8 , QR = 24,  PR = 8

The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.

Perimeter of Δ ABC = Length of AB + Length of BC + Length of AC.

Perimeter of ΔABC = (2x + 7) + (2x) + (2x + 6) = 6x + 13

Perimeter of ΔPQR = (2x) + (3x + 9) + (2x) = 7x + 9

So, 6x + 13 = 7x + 9

 Therefore, x = 4

AB = 2(4) + 7 = 15             PQ = 2(4) = 8

AC = 2(4)+6     = 14          QR = 3(5) + 9 = 24

BC = 2(4)  = 8                    PR = 2(4) = 8

To solve the inequality, multiply both sides by -7 and flip the inequality direction. The solution is n  ≤  -21 or (∞, -21]

Tips to solve linear inequalities:

Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis (  or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.

Example:  x ≥ 2 can be written as [2, ∞), while

                x > 0 is written as (2, ∞)

The given problem:

-n/7 ≥ 3

Multiply both sides by -7. Since we multiply it by a negative number, flip the inequality.

-n/7 . (-7) ≤ 3 . (-7)

n  ≤  -21

Using the interval notation, the solution is (∞, -21]

Student's mean score of the class is 80.6.

Mean:

Mean or the average of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Given,

A student receives test scores of 62, 83, and 91. the student's term project score is 88 and her homework score is 76. each test is worth 20% of the final grade, the term project is 25% of the final grade, and the homework grade is 15% of the final grade.

Here we need to find the student's mean score in the class.

First, we have to convert the percentage into decimal,

Then

=> 20% = 0.20

=> 25% = 0.25

=> 15% = 0.15

Then we have to find the scores from it,

Test A is 0.20 of the total and scores 62.

Test B is 0.20 of the total and scores 83.

Test C is 0.20 of the total and scores 91.

Project F is 0.25 of the total and scores 88.

Work H is 0.15 of the total and scores 76.

Multiply across:

=> A = (0.2 * 62) = 12.4

=> B = (0.2 * 83) = 16.6

=> C = (0.2 * 91) = 18.2

=> F = (0.25 * 88) = 22

=> H = (0.15 * 76) = 11.4

Now we have to add all these values to find the mean,

=> A + B + C + F + H

=> 12.4 + 16.6 + 18.2 + 22 + 11.4

=> 80.6

Therefore, the mean of that student is 80.6

The sample mean of snowfalls in the 18 midwestern cities of the United States is 24. This is calculated by applying the formula of arithmetic mean or average to the given sample of data.

What is arithmetic mean?

An arithmetic mean is examined as very similar to an average. Mathematically, it is obtained by dividing the sum of all objects by the total number of objects.

Calculation of the sample mean for given data

Given the total number of cities = 18

The total amount of snow falls = 20 + 40 + 31 + 7 + 15 + 29 + 25 + 20 + 17 + 32 + 28 + 12 + 34 + 29 + 20 + 17 + 33 + 23

The sample mean = total amount of snowfalls / total number of cities

= 432 / 18

= 24

Hence, the sample mean of the given data is 24.

The distance between two points is the length of the line that will join these two points. The distance can be calculated by taking the square of the difference of the x-coordinates and y-coordinates of the two points, adding them up and taking their square root. In order to understand the formula we have to draw a right angled triangle using these two points, where the line joining the points is the hypotenuse, the difference in the x-coordinates is the base and the difference between the y-coordinates is the height. We use Pythagoras' theorem to find the hypotenuse which gives us the formula of distance between two points

Any arithmetic operation involving two or more fractions, such as addition or subtraction, is achievable if the denominators of both fractions are equal. This is referred to as the common denominator. A common denominator is an integer that has at least one element in common with both denominators other than 1.

Given:

Get a common denominator of 30

3/10 * 3/3 = 9/30  red

Option (b), “a continuum of possible values” is the correct option.

The concepts of continuous probability distribution and normal distribution are used here to solve this problem.

The continuous probability distribution can be defined as the probability distribution of a continuous random variable. Normal distribution is used for finding the probability of a continuous variable when the data is more or less symmetric. The probability of being less than or more than some value can be calculated by calculating the area of the curve to the left of that value.

The probability of a continuous random variable will assume a particular value is zero. Consider a continuous random variable, which follows normal distribution with a mean,  and a standard deviation, which can be represented as to calculate the probability for a random variable, convert the variable into a standard normal variable by the transformation:

Option (a), “an array of individual values” is incorrect because the continuous probability distribution does not contain an array of individual values. Option (c), “a list of possible values” is incorrect because it is not just a list of possible values. Option (d), “counts” is incorrect because the counts is not a characterized by the continuous probability.

False

Probability can be defined as the likelihood or chance of an event occuring. Probability is a branch of Mathematics that deals with the calculation on the chances of happening of a particular event.

For instance, the probability that a student will pass an exam is 1/2.

The students has a total of two possible outcomes, pass or fail.So, the probability of one outcome = 1/total outcome which is 1/2

For the given graph, we have that:

a) It is not a function.

b) The function is discrete.

c) The domain is {-5,2} and the range is all real values.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.

For this problem, we can see that it is not a function, as the values of x = -5 and x = 2 are mapped to multiple values of y.

For this problem, the function is defined only for x = -5 and x = 2, which are integer values, hence it is a discrete function.

Thus, the domain is {-5,2} and the range is all real values.
