You're charged $15 + $2 or $17 per session

If y = # of sessions,

$17y represents the total amount of dollars charged for y sessions

The total cost in dollars, of the class and mat for y sessions will be 17y. Then the correct option is C.

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.

The cost of a yoga class is $15 per session.

In addition, a mat fee of $2 is charged per session.

Then the total cost in dollars, of the class and mat for y sessions will be

C = 15y + 2y

C = 17y

Then the total cost in dollars, of the class and mat for y sessions will be 17y.

Then the correct option is C.

The complete question is attached below.

Answer:

624 pounds

Step-by-step explanation:

If 10 boxes of paper weigh 260 pounds, one box of paper is equal to 26 pounds because 260 divided by 10 is equal to 26. If one box equals 26 pounds, 24 boxes times 26 pounds each is equal to 624 pounds.

Answer:

0.127 kilometers per minute

Step-by-step explanation:

if you can divide the number of miles by the number of minutes: 26.219/128 = 0.205 miles per minute. Next, we can use the proper conversion factor to give the number of kilometers per minute. Since 1 mile = 1.609 km, you can divide 0.205/1.609 to result in 0.127 kilometers per minute

Answer:Sample Response: Find the speed by dividing 26.219 by 128. Convert miles to kilometers by multiplying by the conversion factor, with miles in the denominator and kilometers in the numerator.

Hey there! I'm happy to help!

There is going to be a number 3 units to the right and 3 units to the left. If we go to the right, we add.

-1+3=2

And if we go to the left, we subtract.

-1-3=-4

So, the numbers that are more than 3 units from -1 on a number line is any number greater than 2 or less than -4.

This 3D solid is a strange sideways bowl shape. Each cross section is a ring to show the empty space.

======================================================

Explanation:

Check out the diagram below. The graph was created with GeoGebra. We have y = x^2 in red and x = y^2 in blue.

The gray region is the region between the two curves. We spin this gray region around the horizontal green line y = 1 to generate the answer mentioned above.

Note how (1,1) is a fixed point that does not move as this is on the line y = 1. Every other point moves to sweep through 3D space to create the solid figure. One way you can think of it is to think of propeller blades. Or you can think of a revolving door (the door is "flat" so to speak, but it sweeps out a 3D solid cylinder).

The average speed of the automobile is 53mph.

Average speed is the total distance travelled by the automobile (106 miles) divided by the total hours travelled by the automobile (2 hours). It is the rate of the movement of the automobile.

Average speed = total distance travelled / total time travelled

106 / 2 = 53 mph

Answer:

The null hypothesis is  [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]

The alternative  hypothesis is  [tex]H_a : \sigma^2_1 \ne \sigma^2 _2[/tex]

The conclusion is  

 There is no  sufficient evidence to conclude that there is a difference between the variances of salaries for seniors and managers

Step-by-step explanation:

From the question we are told that

   The variance for seniors is  [tex]s ^2_1 = 2.3[/tex]

   The variance for managers  is [tex]s ^2_2 = 11.3[/tex]

   The  first sample size is  [tex]n_1 = 25[/tex]

    The second sample size is  [tex]n_2 = 26[/tex]

    The significance level is  [tex]\alpha = 0.05[/tex]

The null hypothesis is  [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]

The alternative  hypothesis is  [tex]H_a : \sigma^2_1 \ne \sigma^2 _2[/tex]

Generally the test statistics is mathematically represented as

      [tex]F = \frac{s_1^2}{s_2^2}[/tex]

=>    [tex]F = \frac{2.3}{11.3}[/tex]

=>    [tex]F = \frac{2.3}{11.3}[/tex]

=>    [tex]F = 0.2035[/tex]

Generally the p-value is obtain for the F-distribution table (Reference - Free statistic calculator ) at a degrees of freedom

          [tex]df_1 = 25 - 1[/tex]

          [tex]df_1 = 24[/tex]

and    [tex]df_2 = 26 - 1[/tex]

           [tex]df_2 = 25[/tex]

The p- value is  

        [tex]p-value = f_{0.2035,24,25} = 0.99989[/tex]

So from the calculation we see that

       [tex]p-value > \alpha[/tex]

So we fail to reject the null hypothesis

Kindly check explanation

Step-by-step explanation:

Given the following :

Assume a normal distribution :

Mean (m) = 328

Standard deviation (sd) = 92

To obtain Zscore :

Zscore = (x - m) / sd

What is the probability that the cost will be more than $500?

x = $500

Zscore = (500 - 328) / 92 = 172 / 92 = 1.869 = 1.87

1 - p(Z < 1.87) = 1 - 0.9693 = 0.0307

b. What is the probability that the cost will be less than $250?

x = $250

Zscore = (250 - 328) / 92 = - 78 / 92 = - 0.8478 = - 0.85

p(Z < - 0.85) = 0.1977

c. What is the probability that the cost will be between $300 and $400?

x = 300

Zscore = (300 - 328) / 92 = - 28/ 92 = -0.30

p(Z < - 0.3) = 0.3821

x = 400

Zscore = (400 - 328) / 92 = 72/ 92 = 0.783

p(Z < 0.783) = 0.7823

0.7823 - 0.3821 = 0.4002

d. If the cost to a patient is in the lower 8% of charges for this medical service, what was the cost of this patient’s emergency room visit?

Probability is lower 8%

P (Z < Zscore) = 0.08

Zscore of 0.08 corresponds to - 1.41 on the z table

Zscore = (x - m) / sd

-1.41 = (x - 328) / 92

-129.72 = x - 328

-129.72 + 328 = x

x = 198.28

Answer:

[tex]x^{2} +x+1[/tex]

Step-by-step explanation:

[tex]x^{2} +x+1[/tex] is the only prime polynomial because the others can be factored.

[tex]x^{2} - x -2 \\becomes (x-2)(x+1)[/tex]

[tex]x^{2} -12x+11\\becomes (x-11)(x-1)[/tex]

[tex]x^{2} +2x-8\\becomes (x+4)(x-2)[/tex]

In between these four polynomials, x² + x + 1 is the only prime polynomial.

A prime polynomial doesn't have any factor except 1 and itself.

Given,

x² + x + 1 = 1 × (x² + x + 1)

x² – x – 2 = x² - 2x + x - 2 = x(x - 2) + (x - 2) = (x - 2)(x + 1)

x² – 12x + 11 = x² – 11x - x + 11 = x(x – 11) - (x - 11) = (x - 1)(x - 11)

x² + 2x – 8 = x² + 4x – 2x - 8 = x(x+4) - 2(x+4) = (x-2)(x+4)

Therefore, x² + x + 1 is the only prime polynomial here.

Answer:

When we round to the nearest hundred, we must look at the tens digit.

If the tens digit is 5 or lager, then we round up (we add 1 to the hundreds digit and after that, all the digits are zero.)

If the tens digit is smaller than 5, then we round down (the hundreds digit remains unchanged and after that, we complete with zeros.)

Then, the rounded number is 1900.

a) The greatest whole number that rounds to 1900 would be a number that is rounded down, then it will be:

1949

b) The least whole number that is rounded to 1900 is a number that we round up, this is:

1850

Largest: 1,949

This number is largest because it is closest to 1,900 without the number in the tens place being greater than 5, and the number in the tens place is bigger than 5

Smallest: 1,850

This number is smallest because any smaller number, like 1,849, would round to 1,800, and the number in the tens place is smaller than 5.

Have a good day!
