Crazy boy [7]

Answer:

0.95 = 95% probability that a randomly selected student at this university recycles at least some of the time

Step-by-step explanation:

For a randomly selected student, we have these following probabilities:

0.55 probability that they always recicle.

0.25 probability that they usually recicle.

0.15 probability that they recicle only when it's convenient.

0.05 probability that they never recicle.

What is the probability that a randomly selected student at this university recycles at least some of the time?

Always, usually or only when it's convenient.

0.55 + 0.25 + 0.15 = 0.95

0.95 = 95% probability that a randomly selected student at this university recycles at least some of the time

Given it's midpoint and one endpoint apply the midpoint formula and solve for x and y midpoint (22,15) endpoint (18,6

Nutka1998 [239]

Midpoint formula

mid of (x1,y1) and (x2,y2) is
$( \frac{x2+x1}{2}, \frac{y2+y1}{2})$

so

(22,15)= $( \frac{18+x1}{2}, \frac{6+y1}{2})$
therefor

22= $\frac{18+x1}{2}$
and
15= $\frac{6+y1}{2}$

slv each
22= $\frac{18+x1}{2}$
times both sides by 2
44=18+x1
minus 18 both sides
26=x1

15= $\frac{6+y1}{2}$
times both sides by 2
30=6+y1
minus 6
24=y1

the other point is (26,24)

Graph: Y – 3=1/2(x +2)

tatuchka [14]

Answer:

Step-by-step explanation:y–3=½(x+2)

Multiply through by the denominator (2).

2×y–2×3=½(x+2)×2

2y–6=1(x+2) because the denominator (2) will cancel the other 2 multiplying it

2y–6=x+2

2y=x+2+6

2y=x+8

---. -----

2. 2

•°•y=x+8

-----. Or y=x+4
