Answer:

Step-by-step explanation:

a line parallel to the equation would have the same slope (7/8)

so what we know so far is

y = 7/8x + b

since it has to go through point C (-4, 8)

we’ll plug in those values for x and y (x = -4, y = 8)

8 = 7/8(-4) + b

8 = -28/8 + b

8 = -3.5 + b

b = 11.5

so the equation is

y = 7/8x + 11.5

Brian flips a fair coin 3 times. What is the probability of getting 3 heads?
earnstyle [38]

If Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

The given statement is Brian flips a fair coin 3 times.

We need to find the probability of getting 3 heads.

<h3>What is probability?</h3>

Probability refers to possibility. A random event's occurrence is the subject of this field of mathematics. The range of the value is 0 to 1.

The possible outcomes are {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}.

Total number of outcomes = 8

The number of favourable outcomes =1

So, the probability of getting 3 heads = 1/8 = 0.125

Hence, if Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

Find the mean of the integers: 7,-9,9,-7,0
Aleks04 [339]

Step-by-step explanation:

Add all of the numbers together

7 + 9 + 0 + (-9) + (-7)

simplify it down to:

(7+9+0)= 16

-9 + (-7)= - 16

So, -16 + 16 = 0

then divide 0 by 5 to get the answer of 0

To find the mean you have to add all of the numbers together and then divide by the amount of numbers that you have.
