Answer:

0.0792

Step-by-step explanation:

Independent events are events in which the outcome of one does not affect the outcome of the other. That means what happens in one event has no effect on what happens in another event.

Mathematically, P(A and B) = P(A) * P(B)

The outcome of this is thus multiplying the probability of A by the probability of B

P(A and B) = 0.18 * 0.44= 0.0792

Bond [772]

Answer:

84 couples

Step-by-step explanation:

First add the number of couples that have only one spouse that prefers dramas.

23+39+37+27=126

126 couples out of 250 prefer dramas.

126/250=.56 or 56 percent

To find the answer by making a prediction based on this data, you would find 56% of 150.

150x.56=84 out of the additional 150 surveyed couples will have one spouse that prefers a drama.

Marge purchased bicycle helmets and tire pumps. Each helmet cost $12.00 and each pump cost $8.00. She purchased a total of 18 it
algol [13]

Answer:

11

Step-by-step explanation:

Let the no. of helmet be x

cost of 1 helmet = $12.00

cost of x helmet = $12.00*x = $12x

Let the no. of tire pumps be y

cost of 1 tire pumps = $8.00

cost of x tire pumps = $8.00*y = $8y

Given that total no. of helmet and pump is 18

thus

x + y = 18

y = 18-x

also given

total money spent is $188

thus

12x+8y = 188

using y = 18 - x

we have

12x + 8(18-x) = 188

=> 12x+ 144 - 8x = 188

=> 4x = 188-144 = 44

=> x = 44/4 = 11

Thus, no of helmet bought by Margo is 11.

Solve the equation for the bold variable (h)
Aleonysh [2.5K]

This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.

S = 2·π·r² + 2·π·r · H

Divide each side by 2·π·r :

S/2·π·r = r + H

Subtract r from each side :

H = (S/2·π·r) - r

or

H = (S - 2·π·r²) / (2·π·r)
