Answers

9514 1404 393

Answer:

a. h < 79; w < 295

b. (h, w) = (60, 280)

c. yes

Step-by-step explanation:

We can define h and w to represent the height in inches and the weight in pounds. Then the inequalities representing the given restrictions are ...

h < 79 . . . . . . . . height is less than 6'7"

w < 295 . . . . . . weight is less than 295 pounds

The graph is attached. The solution space is the area where the solutions to the inequalities overlap.

A 5 ft person weighing 280 pounds would meet the given restrictions.

(h, w) = (60, 280) . . . . is a possible solution

(50, 180) is a solution. The height of 50 inches is less than 79 inches, and the weight of 180 pounds is less than 295 pounds. (A person with these measurements would be quite obese.)

_____

Additional comments

As a practical matter, healthy 18-year-olds will generally have a height greater than 59 inches and a weight greater than 95 pounds. Less than 3% of the population will be shorter or lighter than that.

"Good physical condition" may require a body mass index within a certain range. This will put additional (rather narrow) limits on height and weight. We have only shown inequalities and a graph for the specific conditions listed in the problem statement.

We cannot subtract 4/6 from 3/6, so we borrow the 1 as 6/6 and add it to 3/6 to get 9/6. Now we can subtract 4/6 from 9/6.

Answers

Answer:

Slope = -1 . Parallel lines have the same slope. The slope is a coefficient of the x-term.

Step-by-step explanation:

y - x = 5

y = x + 5 slope = 1

The slope of the line parallel to the given line is 1.

What is slope?

Slope is a value that describes the steepness and direction of a line. In variable format, it is commonly represented by the letter m.

The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run.

Given that the equation of a line y - x = 5, we need to find the slope of the parallel to the same,

Converting the equation in slope-intercept form,

y - x = 5

y = x + 5

Comparing with standard form of the equation of the line y = mx + c, where m is the slope,

Hence, the slope of the given line is 1,

We know that the slopes of the parallel lines are equal.

So, the slope of the asked line is 1.

Hence, the slope of the line parallel to the given line is 1.

Answer: graph 1:no graph 2:no graph 3: yes graph 4: yes graph 5: no

Step-by-step explanation:

Answer:

Graph 1 I think is yes because when determining if a function, you do the vertical line test meaning you place an imaginary vertically on the graph and if there is 2 points on the line at once, like for graph 5 or 6, then it isn't a function.

Therefore,

Graph 1: Yes

Graph 2: No

Graph 3: Yes

Graph 4: Yes

Graph 5: No

Graph 6: No

For graph 1, it is way to close to tell if a function or not. So, I would say go with your gut.

[tex]x = 40°[/tex]

Step-by-step explanation:

The two angles shown are vertical angles and thus, by their definition, they are equal to each other. Therefore, we can write

[tex]3x = 2x + 40[/tex]

We can move the 2x term to the left side by adding [tex]-2x[/tex] to both sides of the equation:

[tex]3x - 2x = 2x - 2x + 40[/tex]

which will then give us

6. The cost C of hiring a taxi is given by the formula C = 4 + 1.25m where m is the number of miles driven. Make a table showing the cost of hiring the taxi to drive 1, 2,3, and 4 s, Dete whether the cost of the taxi is proportional to the number of miles driven. Explain your reasoning.

Answers

The ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.

What is proportional?

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)

To find the cost of hiring a taxi to drive 1, 2, 3, and 4 miles, we can use the formula:

C = 4 + 1.25m

For m = 1, we have:

C = 4 + 1.25(1) = 5.25

For m = 2, we have:

C = 4 + 1.25(2) = 6.5

For m = 3, we have:

C = 4 + 1.25(3) = 7.75

For m = 4, we have:

C = 4 + 1.25(4) = 9

So the table of costs for driving 1, 2, 3, and 4 miles is:

Miles (m) Cost (C)

1 5.25

2 6.5

3 7.75

4 9

To determine whether the cost of the taxi is proportional to the number of miles driven, we can check whether the ratios of cost to distance are equal. If they are, then the cost is proportional to the number of miles driven.

Let's check the ratios:

C(1)/1 = 5.25/1 = 5.25

C(2)/2 = 6.5/2 = 3.25

C(3)/3 = 7.75/3 = 2.58333...

C(4)/4 = 9/4 = 2.25

Hence, the ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.

B) 0
C) 0.5

The probability of those telling the truth is an illustration of experimental probability.

The probability that the next person tells the truth is 0.23

The given parameters are:

[tex]\mathbf{n = 100}[/tex] -- sample size

[tex]\mathbf{x = 23}[/tex] -- those telling the truth

So, the probability that the next person tells the truth is:

[tex]\mathbf{Pr = \frac xn}\\\\\\[/tex]

Substitute values for x and n

[tex]\mathbf{Pr = \frac{23}{100}}[/tex]

Divide 23 by 100

[tex]\mathbf{Pr = 0.23}[/tex]

In the given figure find the value of the unknown interior angle x in the following figure.

Answers

Answer:

Therefore, the measure of angles x is 70°.

Step-by-step explanation:

From the given figure ,

115° is the exterior angle

x° and 45° are the two interior opposite angles to 115°

We know that

An exterior angle formed by extending the side of a triangle is equal to the sum of the two interior opposite angles

⇛ x° + 45° = 115°

⇛ x° = 115°-45°

⇛ x° = 70°

Therefore , x = 70°

Step-by-step explanation:

Question 3

The common difference of an arithmetic sequence is the difference between consecutive terms.

Therefore, to find the common difference, subtract one term from the next:

⇒ d = 1.8

Question 4

Given arithmetic sequence: [tex]a_n=10n-14[/tex]

To find the 8th term, substitute n = 8 into the equation:
