The following relation is a function: {(-8, – 9), (-4, 5), (1, 5), (4, 7)}
Nookie1986 [14]

Answer:

Yes

Step-by-step explanation:

The following relation is a function. When graphed, it passes the vertical line test, and you don't go across any two points at the same time. So therefore, it is a function. Another easy way to determine if the relation is a function is by taking a look at the x-coordinates. If any x-coordinates are the same, then it's not a function. If all x-coordinates are the same, then it's a function.

Hope this helps. Please mark brainliest.

Jenna goes for a jog every morning. The line plot shows the number of hours she jog for 5 days how many total hours did she draw
vichka [17]
You need to show the line put. If you show the line plot i may be able to answer. But F.Y.I. you are going to probably using proportions or need to multiply the hours she jogs in one day by the 5 days. Hope this helps.

You have a bag with two coins. One will come up heads 40% of the time, and the other will come up heads 60%. You pick a coin ran
Gnom [1K]

Answer:

13/50

Step-by-step explanation:

First, we need to put all the possible scenarios.

Let's call coin A as the coin that flips head 40% of the time, and coin B the 60% of the time.

Now, 40% in fraction is 40/100 = 4/10 = 2/5 for coin A. This is the probability of the coin A to get head. (Pa)

60% of the time is 60/100 = 6/10 = 3/5. Probability to get head in coin B (Pb)

Now, we don't know which coin is picked, all we know is that the first flipping is head. so, as the coins are picked randomly, we have 1/2 probability to choose either coin A or coin B, so, let's suppose we picked coin A:

Pa = 1/2 * 2/5 = 2/10 * 2/5 = 4/50

If the coin picked is coin B:

Pb = 1/2 * 3/5 = 3/10 * 3/5 = 9/50

So, finally the probability that if we flip the coin a second time, to get a head, no matter which coin was picked, is just the sum of both probabilities so:

P = 4/50 + 9/50 = 13/50

The area of a rectangle is 24 square inches. Determine both dimensions if the length is 6 inches less than three times the width
Rama09 [41]

Answer:

width is 4 inches

length is 6 inches

Step-by-step explanation:

the length is 6 inches less than three times the width

l = 3w - 6

a = l * w

a = (3w - 6)w

a = 3w^2 - 6w

area of the rectangle is 24 square inches

3w^2 - 6w = 24

subtract 24 from both sides

3w^2 - 6w - 24 = 0

Divide both sides by 3

w^2  - 2w - 8 = 0

Factor

(w - 4)(w + 2) = 0

w = {-2, 4}

disregard the negative root since measurement must be positive

w = 4

l = 3w - 6

l = 3(4) - 6

l = 6
