Answers

Answer:

Step-by-step explanation:

to find slope, m is slope

m=(y2-y1)/(x2-x1)

let’s use one of the coordinates here:

(50,150) and (100,150)

m= (150-150)/ (100-50)

this is the slope

Marla filled up her car's gas tank and then went on a trip. After she drove 329 miles, she filled her tank with 14 gallons of gas. If she drove the same number of miles on each gallon of gas, how many miles per gallon did she drive?

Answers

Answer:

23 1/2 miles per gallon

Step-by-step explanation:

We start with dividing 329 miles with 14 gallons because it asks to find the number of miles on each gallon of gas -

          Miles

-----------------------------     =

Each gallon of gas

329 ÷ 14 = 23 1/2 miles per gallon

A student has to take two quizzes tomorrow. He has only enough time to study for one of them. The history quiz has 5 true or false questions. The science quiz has 3 multiple choice questions. The student calculates the probability that he will get all the questions correct by guessing. The student will study for the quiz on which he is likely to do worse by guessing. Which quiz should he study for?


A. History, because he must get more questions correct.

B. Science, because the probability of getting all the questions correct is 0.016, which is lower than for history (0.031).

C. History, because the probability of getting all questions correct is 0.031, which is lower than for science (0.75).

D. Science, because the probability of getting all questions correct is 0.075, which is lower than for history (0.25).

Answers

Answer: option B

Step-by-step explanation:

Miguel has to take two quizzes

1) 4 true or false questions on History with a 0.5 chance of acing the quiz

Expected number of correct questions = np

n = number of questions

p = probability of acing the test

Expected number of correct questions = 4 × 0.5 = 2

2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.

Expected number of correct questions = 0.2 × 3 = 0.6

It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.

Based on the probabilities of passing, the quiz the student should study for is B. Science, because the probability of getting all the questions correct is 0.016, which is lower than for history (0.031).

Why should the student study science?

If the student does not study science, they will most likely fail because the probability that they get all questions correct without studying is quite low.

If he must, the student can give up history because he still has a higher chance of passing it without studying.

13 = 1/6y +2x plz help

Answers

Answer:

in standard form - y+12x=78

in slope intercept form - y=-12x+78

Step-by-step explanation:

standard form

13=1/6y+2x

multiply both sides by 6

78=y+12x

y+12x=78

slope intercept

13=1/6y+2x

subtract 1/6y from both sides

13-1/6y=2x

subtract 13 from both sides

-1/6y=2x-13

change the signs on both sides of the equation

1/6y=-2x+13

divide both sides by 1/6

y=-12x+78

Answer:

x >= 7 OR x < -8

n <= -3 AND n > -6

Step-by-step explanation:

15) 7x - 6 >= 43 OR 10x + 4 < -76

7x >= 43 + 6 OR 10x < -76 - 4

7x >= 49 OR 10x < -80

x >= 7 OR x < -8

you can draw based on this

for >= it is full dot for < it is like circle on the graph

you have to draw both x>= 7 , x < -8 on the same line because it is OR

so both ranges of x are possible

21) 3 + 2n <= -3 AND 1 - 3n < 19

2n <= -3 -3 AND -3n < 19 - 1

2n <= -6 AND -3n < 18

n <= -3 AND 3n > -18

n <= -3 AND n > -6

so it lies between -6 and -3

Answer:

Equation: y = 2x — 3

Slope: 2

Y-intercept: —3

Step-by-step explanation:

m=∆y/∆x

= —3—(—1)/0—1

= —2/—1

= 2

We Know: y - y0 = m (x—x0)

y (3) = 2 (x 0)

y + 3 = 2x

y = 2x 3

So
