Answer:

A: (-1,0)

B: (1,1)

C: (5,3)

(0,½)

(7,5) doesn't lie on the line

Step-by-step explanation:

Slope: (3-1)/(5-1) = ½

y = ½x + c

0 = ½(-1) + c

c = ½

y = ½x + ½

(0,½) is on the line

y = ½x + ½

Check for (7,5)

5 = 7/2 + 1/2

5 = 4 is a false statement

Answer:

see below

Step-by-step explanation:

a A  (-1,0)  B  (1,1)  C (5,3)

Remember the x coordinate is horizontal and the y coordinate is vertical

b  We notice that we go over 2 and up 1

  another point would be (5+2, 3+1) = (7,4)

  We could also go to the left 2 and down 1

  a second point would be  (-1 -2, 0-1) = (-3, -1)

c  The point (7,5) is not on the line.  We found that the point (7,4) is on the line.  There is only one point at each x coordinate on the line and it is at (7,4)

(1 point) Two six-sided dice are rolled (one red one and one green one). Some possibilities are (Red
anygoal [31]

Complete question:

Two six-sided dice are rolled (one red one and one green one). Some possibilities are (Red= 1, Green=5) or (Red=2, Green=2) etc.

a)How many total possibilities are there?

For the rest of the questions, we will assume that the dice are fair and that all the possibilities in (a) are equally likely.

b)What is the probability that the sum on the two dice comes out to be 11?

c)What is the probability that the sum on the two dice comes out to be 7?

d)What is the probability that the numbers on the two dice are equal?

Answer:

Kindly check explanation

Step-by-step explanation:

Total probabilities :

Total possible outcomes on each dice = 6

Total probabilities = 6² = 36

b)What is the probability that the sum on the two dice comes out to be 11?

Total required outcome = 2

Total possible outcomes = 36

Probability = required outcome / Total possible outcomes

P(sum on both dice = 11) = 2 / 36 = 1/18

c)What is the probability that the sum on the two dice comes out to be 7?

Required outcome = 6

Possible outcomes = 36

P(obtaining a sum of 7) = 6/36 = 1/6

d)What is the probability that the numbers on the two dice are equal

= required outcome / possible outcomes

Required outcome = 1,1 ; 2,2; 3,3; 4,4 ; 5,5 ; 6,6

= 6/36 = 1/6

An animal shelter has a 58% adoption rate for puppies. Of all puppies in the shelter, 80% live to be 7 years or older. Of the pu
dexar [7]

Answer:

P(A∩B) = 0.522

Step-by-step explanation:

Let's call A the event that a puppy is adopted and B the probability that a puppy live 7 or more years

So, the probability P(A∩B) that a randomly selected puppy in the shelter will get adopted and live 7 or more years is:

P(A∩B) = P(A)*P(B/A)

Because A and B are not independents.

Then, the probability P(A) that a puppy is adopted is 58% and the probability P(B/A) that a puppy live 7 or more years given that the puppy is adopted is 90%.

Finally, replacing the values, we get:

P(A∩B) = 0.58*0.9 = 0.522

It means that the 52.2% of the puppies are adopted and live 7 or more years.

How do you tell if the equation 2y=8 is linear; How do you graph it?
GarryVolchara [31]
Solve for y and then graph it on a graphing calculator or since it doesn’t have a exponent you know it’s just a line because it would be the like y=4 which is a horizontal line at 4
