Answer:

0.4490

Step-by-step explanation:

P(tested positive )=P(uses steroid and tested positive )+P(not uses steroid and tested positive )

=0.009*0.9+0.994*0.01=0.01804

Therefore:

Therefore P(uses steroid|tested positive )=P(tested positive & uses steroid)/P(tested positive )=0.009×0.9/0.01804=0.4490

The distance from the base of the tree to the tallest would be 14.21 cm

<h3>We have the following data points in this question</h3>

X1 = 8 feet

y1 = 16 feet

x2 = 11 feet

y2 = 9 feet

To proceed with the solution we have to

We have to solve for the shorter tree

$\sqrt{(y2 -y1)^2 + (x2-x1)^2} \\\\= \sqrt{9-0^2 + 11-0^2}$

<em>= </em>9² + 11²

= √81 +121

= 14.21

<h3>For the taller tree we would have</h3>

√8² + 16²

= √64 +256

= 17.89

If f(x)=x-2 and g(x)=1/2x, find g(f(x))

Scilla [17]

Answer:

hello :

If f(x)=x-2 and g(x)=1/2x,

g(f(x)) = g ( x - 2 )

= 1/2(x-2)

g(f(x)) = (1/2)x - 1

Given parameters:

Weight of baby at birth = 7.25 pounds

Unknown:

Weight at the end of 8months = ?

Solution:

From the second sentence;

Weight at the end of the eighth month = 212 x weight at birth.

Input the parameters and solve;

Weight at the end of eighth month = 212 x 7.25 = 1537pounds
