Find the missing probability in the table below.

1 answer:

7 0

X 1 2 3 4
p(x) 0.40 0.20 0.15 ?

If the items are only 4. The total of the probability must be 1 or 100%

1 - 0.40 - 0.20 - 0.15 = 0.25

The probability of 4 is 0.25.

The hypotenuse of a right triangle is 50 and the short leg is 30, find the projection of the leg onto the hypotenuse

gladu [14]

Consider the attached figure. All the triangles shown are similar, so

CB/CA = CD/CB
30/50 = projection/30
projection = 30^2/50
projection = 18

Yanka [14]

5400*0.04(rate)=216

Because it's simple interest for 7 years, 216*7 should be the answer

So $1512

Can someone answer this for me :)

Darya [45]

Answer:

y = -2x + 3

Step-by-step explanation:

y = mx + b

slope = m

m = y2 - y1/x2 - x1

-3 - 3/3 - 0 = -6/3

m = -2

y = -2x + b

b = y-intercept

b = 3

y = -2x + 3
