Answer: 12.2408

Step-by-step explanation:     This is what I got I hope I got it right:)

Answer:

Step-by-step explanation:

Response Variable: Miles per gallon

Predictor Variables: Weight, Horsepower

The multiple regression equation would be: M = aW + bH + c

where M = miles per gallon

a = slope of the graph of W on M OR rate of change in M due to change in W

W = weight

b = slope of the graph of H on M OR rate of change in M due to change in H

H = horsepower

c = intercept of M on the y-axis OR constant variable

How might the car rental company use this model?

The car rental company might use the regression model to determine the following:

- Effect of weight (of car) on miles run per gallon (of premium motor spirit)

- Effect of horsepower on miles per gallon; etc.

Step-by-step explanation: Uh if Lori has 136 crayons. And rick has 10 more than her He would have 146 And tom has 10 fewer crayons than rick so he would have 136

Lori:136

Rick:146

Tom:136

And idk if u need this or not but if u want it all together it would be: 418

Hope this helps!)

Rick has 146 crayons,  Lori has 136 crayons and Tom has 136 crayons'

Let the number of crayons Rick have be x

Let the number of crayons Lori has be y

Let the number of crayons tom has be z

If Rick has 10 more crayons than Lori, then;

x = 10 + y

Since Lori has 136 crayons, hence y = 136

x = 10 + 136

x = 146

If Tom has 10 fewer crayons than Rick, then;

z = x - 10

z = 146 - 10

z = 136

Hence rick has 146 crayons,  Lori has 136 crayons and Tom has 136 crayons'

123.456 RONDED TO THE NEAREST HUNDREDTH.

Answer:

123.46

Answer:

123.46 is probably the answer

Answer:

$71713

Step-by-step explanation:

If each chair cost $199 then multiple 199 by 355

[tex]199*355= 70645[/tex]

If they still have 1068 then add that into the sum

[tex]70645+1068=71713[/tex]

So your answer is $71713

Answer: $71,713

Step-by-step explanation:

First you would multiply 355 by 199 to get 70,645. Next you would add the remainder of what they had, $1,068, and get the answer. hope this helps.

Answer:

-1

Step-by-step explanation:

Solve for y into y=mx+b

2x-2y=20

-2y=-2x+20

y=(-2x+20)/-2

y=x-10

the slope is m, so it’s 1

A line perpendicular to that would be -1

Answer:

48 students

Step-by-step explanation:

Represent algebra with A and physics with P

Given

Total = 50

n(A) = 39

n(P) = 16

n(Both) = 7

Required

Determine students taking Algebra or Physics

This is calculated using

n(A or P) = n(A) + n(P) - n(Both)

n(A or P) = 39 + 16 - 7

n(A or P) = 48

A total of 48 students are enrolled in either physics or algebra.

Number of students taking algebra n(A)= 39

Number of students taking physics n(B)= 16

Number of students taking both subjects n(A∩B)= 7

So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)

The union of two sets is a set containing all elements that are in A or in B (possibly both).

As we know,

n(A∪B) = n(A) + n(B) - n(A∩B)

n(A∪B) = 39+16-7

n(A∪B) = 48

Therefore, A total of 48 students are enrolled in either physics or algebra.

Answer:

(x - 3)(2x + 7) = 2x^2 + x - 21

Step-by-step explanation:

2x^2 + x - 21 = (__ - 3)(__ + 7)

The first term of the trinomial is 2x^2 which can be factored into 2x * 2.

You need to place 2x in one blank and x in the other blank.

Try it both ways. Then multiply the factors out to see which one gives you the correct middle term.

Try 2x - 3.

(2x - 3)(x + 7) = 2x^2 + 14x - 3x - 21 = 2x^2 + 11x - 21

This gives the middle term 11x, but we need the middle term to be x, so now we try x - 3.

(x - 3)(2x + 7) = 2x^2 + 7x - 6x - 21 = 2x^2 + x - 21

This gives the correct middle term, x, so this is the correct factorization.

Answer:

(x - 3)(2x + 7) = 2x^2 + x - 21

Domain: (- ∞,0) U (0, ∞)

Range: ( - ∞,0) U (0, ∞)

Step-by-step explanation:

The domain and range of the function are:

Domain: (- ∞,0) U (0, ∞)

Range: ( - ∞,0) U (0, ∞)

Domain and  Range of function

The domain are the input values for which a function exist while the range are output value for which the function exist.

Given the function:

g(x) = 35x^5

The function can exist on all real values since we will have a correspoding value of y for every value of x.

Hence the domain and range of the function are:

Domain: (- ∞,0) U (0, ∞)

The side lengths of the image after the dilation = 13.5 cm and 20.25cm

Step-by-step explanation:

A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.

Dilation can also be referred to as scale factor

6cm × 2.25 = 13.5 cm

9 cm × 2.25 = 20.25 cm

The side lengths of the image after the dilation = 13.5 cm and 20.25cm

Complete Question

Assume that females have pulse rates that are normally distributed with a mean of u = 76.0 beats per minute and a standard deviation of 12.5 beats per minute. If 1 adult female is randomly selected, find the probability that her pulse rate is between 70 beats per minute and 82 beats per minute. The probability is (Round to four decimal places as needed.)

Answer:

0.3688

Step-by-step explanation:

The formula for calculating a z-score when given a random sample of numbers is is z = (x-μ)/σ/√n

where x is the raw score,

μ is the population mean, and

σ is the population standard deviation.

mean = 76.0 beats per minute and a standard deviation = 12.5 beats per minute.

n = number of random samples = 1

For 70 beats per minute

z = 70 - 76/12.5/√1

z = -0.48

Probability value from Z-Table:

P(x = 70) = 0.31561

For 82 beats per minute.

z = 82 - 76/12.5/√1

z = 0.48

Probability value from Z-Table:

P(x = 82) = 0.68439

The probability that her pulse rate is between 70 beats per minute and 82 beats per minute.

P(x = 82) - P(x = 70)

0.68439 - 0.31561

= 0.36878

≈ 0.3688

Answer:
