Kyle asked a random group of students what their favorite sport was. The results are below. Boys Girls Basketball 10 8 Football

Ronch [10]

Answer:

The probability that Kyle will pick a girl who likes football is 12.5%.

Step-by-step explanation:

The data provided is as follows:

Boys Girls Total

Basketball 10 8 18

Football 25 7 32

Soccer 9 19 28

Baseball 18 22 40

Total 62 56 118

Compute the probability that Kyle will pick a girl who likes football as follows:

$P(F|G)=\frac{n(G\cap F)}{n(G)}$

$=\frac{7}{56}\\\\=0.125\\\\=12.5\%$

Thus, the probability that Kyle will pick a girl who likes football is 12.5%.

Se cocina una pizza de 20 cm de radio, en su interior se coloca al azar 12 piezas de salami

Furkat [3]

Answer:

The area of cheese is 388π cm.

Step-by-step explanation:

Given that,

Radius of pizza = 20 cm

Number of pieces = 12

Radius of circle = 1 cm

We need to calculate the area of pizza

Using formula of area

$A=\pi\times r^2$

Put the value into the formula

$A=\pi\times20^2$

$A=400\pi\ cm^2$

We need to calculate the area of circle

Using formula of area

$A'=\pi\times r^2$

Put the value into the formula

$A'=\pi\times1^2$

$A'=\pi\ cm^2$

Now, we multiply the result by 12 because they are 12 salamis.

So. the area of salamis will be

$A'=12\pi\ cm^2$

We need to calculate the area of cheese

The total area of the pizza and subtract the area of the salamis

$A''=A-A'$

Put the value in to the formula

$A''=400\pi-12\pi$

$A=388\pi\ cm^2$

Hence, The area of cheese is 388π cm.
