Three coins are tossed, what is the probability that
theoutcome will be heads?

The probability that the outcome will be heads = 1/2

Step-by-step explanation:

Sample of Total outcome: HHH THH HHT HTT THH TTH TTH TTT

Possible outcome of heads = more than one head = HHH THH HHT THH

Where H = head, T = tail.

Probability = n(possible outcome)/n(total outcome)

n(possible outcome) = 4

n( total outcome) = 8

Therefore,

Probability = 4/8.

Probability = 1/2

Thus The probability that the outcome will be heads = 1/2

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
