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%.

The right triangle above has height h centimeters and hypotenuse t centimeters. What is the area, in square centimeters, of the

White raven [17]

Answer:

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: $A = \frac{h*w}{2}$

Pytagoras theorem: $h^{2} + w^{2} = t^{2}$

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

$h^{2} + w^{2} = t^{2}$

$w^{2} = t^{2} - h^{2}$

$w = \sqrt{t^{2} - h^{2}}$

So the area is:

$A = \frac{h*w}{2}$

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$
