Shortly after creating a car washing business, you made $65 washing ten
cars. Then after fifteen cars, you made $115. Build a model. Write an
explanation for the slope. Write an explanation for the y-intercept. How
many cars have you washed if you have made $255?

Answers

Answer:

A) For the slope;

Rate of change in profit per change in number of cars washed = 10

B) when he had not washed any car, he was in debt of of $35

C) When he made $255, he had washed 29 cars

Step-by-step explanation:

Slope intercept equation of a line is;

y = mx + c

you made $65 washing ten

cars. Thus, x = 10 and y = 65

So, 65 = 10m + c - - - - (eq 1)

Then after fifteen cars, you made $115.

Thus, x = 15 and y = 115

So; 115 = 15m + c - - - - (eq 2)

Subtract equation 1 from eq(2) to get;

115 - 65 = 15m - 10m + c - c

50 = 5m

m = 50/5

m = 10

Putting 10 for m in eq 1 gives;

65 = 10(10) + c

65 = 100 + c

c = 65 - 100

c = -35

A) Since the slope is m = 10 and slope is m = Δy/Δx, it means that;

Rate of change in profit per change in number of cars washed = 10

B) c = -35 is the y-intercept.

This means when x = 0, y = - 35.

It implies that when he had not washed any car, he was in debt of of $35

C) since we have the slope and intercept, equation is;

y = 10x - 35

If he has made $255,then we have;

255 = 10x - 35

255 + 35 = 10x

290 = 10x

x = 290/10

x = 29 cars washed.

Jill estimated she would spend $50.00 a month on clothing. However, at the end of the year she discovered she actually spent $711.00 on clothing that year. What was her forecast error for that budget item?Hint 12 months in a year

Answers

50$ per month for 12 years would mean she spent only (50 x 12) 600$ per year.

She actually spent $711, her forecast was off target by (600-7111) $111.

She exceeded her budget by $111

The solution is, the value of the given inequality is : X>−3.

What is inequality?

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

the given inequality is:

X+5 > 2

Subtract 5 from both sides.

X+5- 5 > 2 - 5

X>2−5

Simplify,

2-5 = -3

so, we get,

AND THE ANSWER IS

X>−3

Hence, The solution is, the value of the given inequality is : X>−3.

Guests at a Beaumont hotel stay for an average of 9 days with a standard deviation of 2.4 days. Assume that the length of stay is normally distributed. Assume that we select randomly 1000 guests. How many of those guests can be expected to stay between 7 and 14 days

Answers

Answer:

778

Step-by-step explanation:

We have the length of stay as X

X~N (9,(2.4))

The sample is given as n = 1000

P(7<x<14) is what we are trying to get

P(7-9/2.4 < x-9/2.4 < 14-9/2.4)

= P(-0.83<z<2.08)

P(z<2.08)-p(z<-0.83)

When we go to the z table,

0.981-0.0203

= 0.778

0.778x1000

= 778

So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.

You have the correct sequence of reasons

Here's what the full step by step picture looks like

3.25(1.25x + 0.5) = 10.5 ................ given

4.0625x + 1.625 = 10.5 ................ distributive property

4.0625x = 8.875 ................ subtraction property of equality

x = 2.18461538461539 ....... division property of equality

---------------------------

Notes:

The decimal value of x is approximate. Round it however you need.In the third step, we subtracted 1.625 from both sidesIn the fourth step, we divide both sides by 4.0625

Answer:

I am pretty sure that is right

Step-by-step explanation:

[tex]3.25(1.25+0.5) = 10.5[/tex] is given

Then you distribute the [tex]3.25\\[/tex] to the [tex]1.25x[/tex] and the [tex]0.5[/tex].

[tex]3.25(1.25x)=4.06x[/tex]

[tex]3.25(0.5)=1.6[/tex]

So the new equation would be [tex]4.06x + 1.6= 10.5[/tex]

Then you would subtract [tex]1.6[/tex] from each side to get [tex]4.06x=8.9[/tex]

Finally you would divide each side by [tex]4.06[/tex] to get [tex]x= 1.93[/tex].
