Answer:

37.65

Step-by-step explanation:

Take 2447.25, divide by 52 (there are 52 weeks in a year) and mutiply by 0.8 (80%), and then you have the answer!

The amount of money deducted from each payback will be $37.65.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Heather's employer pays 80% of her health insurance premium. If the annual premium is $2447.25 and she is paid weekly.

The payment will be calculated as,

Pay = ( 2447.25 / 52 ) x 0.8

Pay = $37.65

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.

4)  a₈ = 66

5)  a)  138  

    b)  55

    c)  [tex]a_n=55n+83[/tex]

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 = 5 - 3.2

⇒ 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:

[tex]\implies a_8=10(8)-14[/tex]

[tex]\implies a_8=80-14[/tex]

[tex]\implies a_8=66[/tex]

Question 5

General form of an arithmetic sequence:

  [tex]a_n=a+(n-1)d[/tex]

where:

a)  The first term is the initial amount Mrs Speas has in her bank account:

b) The common difference is the amount she deposits each week:

c) The iterative rule for the amount of money she has after n weeks is:

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.

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.

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

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°

Answer:

5/6

Step-by-step explanation:

1 1/2 - 2/3 =

= 1 3/6 - 4/6

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.

= 9/6 - 4/6

= 5/6

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.
