Answer:

A) 1/3200000

B) 19/20

Step-by-step explanation:

Percentage population of graduates = 5

Proportion of graduates from 100 random samples = percentage × number of samples

Proportion of graduates = 0.05 × 100 = 5

Probability of having 5 graduates among the 100 random samples:

P(1 graduate) = possible outcome / total required outcome

P(1 graduate) = (5 / 100) = 1/20

P(5 graduates) = (1/20)^5

P(5 graduates) = 1/3200000

Probability of never being a graduate = (1 - probability of being a graduate)

Probability of never being a graduate = ( 1 - (1/20)) = 19/20

The equation sin(40o) =b/20 can be used to determine the length of line segment AC. What is the length of AC? Round to the neare
boyakko [2]
For this case we have the following equation:
 sin (40o) = b / 20
 Clearing b we have:
 20 * sin (40o) = b
 Therefore, the length of the AC segment is given by:
 b = 12.9
 Answer:
 
the length of AC is:
 
b = 12.9

A basket of fruit holds 12 apples, 24 pears, and 16 oranges. Find the ratio of apples, pears, and oranges in the basket.
miv72 [106K]

Answer:

3:6:4

Step-by-step explanation:

We are given that

Number of apples in the basket=12

Number of pears in the basket=24

Number of oranges in the basket=16

We have to find the ratio of apples, pears and oranges in the  basket.

12=4\times 3

24=4\times 3\times 2

16=4\times 2\times 2

HCF (12,24,16)=4

Now, divide each number by HCF

Then, we get

3:6:4

Therefore, the ratio of apples, pears and oranges in the  basket.

3:6:4
