Answers

Step-by-step explanation:

equation of the line passing through two points

x-x1/x2-x1=y-y1/y2-y1

x-(-8)/1-(-8)=y-2/9-2

x+8/9=y-2/7

7x+56=9y-18

9y=7x+56+18

y=7/9x+74/9

y=mx+b m is the slope

Answer:    P(F) = 0.35

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

Work Shown:

P(E or F) = P(E) + P(F) - P(E and F)

0.55 = 0.40 + P(F) - 0.20

0.55 = P(F) + 0.20

P(F) + 0.20 = 0.55

P(F) = 0.55 - 0.20

P(F) = 0.35

---------

note: Sometimes you may see the formula as

P(E and F) = P(E) + P(F) - P(E or F)

but it's an equivalent form to the first equation above.

Drove 260 km using 12 liters of gas at this rate how many liters of gas would he need to drive 286km

Answers

Answer:

We calculate the amount of gas used per km and multiply it by 286

Step-by-step explanation:

If we drive for 260km and use 12 litres of gas that means that we use

[tex]\frac{12}{260}[/tex] litres per km.

Now we multiply it by 286:

[tex]\frac{12}{260} *286 = \frac{858}{65} = 13.2[/tex]

what is the measure of CAB?

Answers

Angle CAB = 84°

∠CAB and the angle above it whose measure is 84° are vertically opposite angles , which means their measure will be equal .

∴ The measure of angle CAB = 84°

By the definition of vertically opposite angle, Measure of an angle CAB is, 84°.

What are Parallel lines?

Parallel lines are those lines that are equidistance from each other and never intersect each other.

We know that;

The vertically opposite angles are equal to each other.

Here, ∠CAB and the angle above it whose measure is 84° are vertically opposite angles.

Hence, Measure of ∠CAB = 84°

Write the multiple regression equation for miles per gallon as the response variable. Use weight and horsepower as predictor variables. See Step 5 in the Python script. How might the car rental company use this model

Answers

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.

C. An arithmetic sequence is an exponential function whose domain is restricted to the set of non-negative integers.
D. A geometric sequence is an exponential function whose domain is restricted to the set of non-negative integers.

Answers

Answer:

A and D.

Step-by-step explanation:

A sequence is a set of the objects or numbers in a specific order. It is a function whose domain is a set of natural numbers or non-negative integers i.e. {1, 2, 3,..}

(A)

"An arithmetic sequence is a linear function whose domain is restricted to the set of non-negative integers."

The general form an arithmetic sequence is:

[tex]a_{n}=a_{1}+(n-1)d[/tex]

The function is linear. The sequence consists of either numbers that are increasing or decreasing based on the value of d, the common difference.

So, the statement provided is True.

(D)

"A geometric sequence is an exponential function whose domain is restricted to the set of non-negative integers."

The general form an geometric sequence is:

[tex]a_{n}=a_{1}\cdot r^{n-1}[/tex]

The function is exponential. The sequence consists of either numbers that are exponentially increasing or decreasing by the factor r, the common ratio.

So, the statement provided is True.

Step-by-step explanation:

an object is thrown upward at a speed of 74 feet per second by a machine from a height of 18 feet off the ground. The height h of the object after t seconds can be found using the equation h=-16t^2+74t+18​

Answers

Answer:

First part:

 

Set h(t) = 73 and solve for t.

 

-16t2 + 64t + 16 = 73

 

-16t2 + 64t - 57 = 0

 

Solve this quadratic equation for t.  You should get 2 positive solutions.  The lower value is the time to reach 73 on the way up, and the higher value is the time to reach 73 again, on the way down.

 

Second part:

 

Set h(t) = 0 and solve the resulting quadratic equation for t.  You should get a negative solution (which you can discard), and a positive solution.  The latter is your answer.

The volleyball team and the wrestling team at Stamford High School are having a joint car wash today,

and they are splitting the revenues. The volleyball team gets $5 per car. In addition, they have already

brought in $50 from past fundraisers. The wrestling team has raised $94 in the past, and they are

making $1 per car today. After washing a certain number of cars together, each team will have raised the

same amount in total. What will that total be? How many cars will that take?

PLEASE SHOW WORK THANK YOU

Answers

Answer:

Money raised by each team = 94 + 11 = $105

Number of cars washed = 11

Step-by-step explanation:

Money already present with volleyball team = $50

Money raised by washing each car by volleyball team = $5

Let the number of cars washed = [tex]x[/tex]

Money raised by washing cars = $5[tex]x[/tex]

Money already present with volleyball team = $94

Money raised by washing each car by volleyball team = $1

Money raised by washing cars = $1[tex]x[/tex] = $[tex]x[/tex]

Given that, both the teams have raised same amount of money:

[tex]50+5x=94+x\\\Rightarrow 44=4x\\\Rightarrow x=11[/tex]

Money raised by each team = 94 + 11 = $105

Number of cars washed = 11
