Find the measure of line f and g

In this case we use intersecting secant theorem

According to this theorem, GF*GE = GH*GA

So,we plug in the values

(x-3)*(x-3+9) =(x-2)*(x-2+6)

(x-3)*(x+6) =(x-2)*(x+4)

x^2 +6x -3x -18 =x^2 +4x -2x -8

x^2 +3x -18 =x^2 +2x -8

x^2 +3x -18 -x^2 -2x +8 =0

x -10 =0

x=10

So,FG =x-3 = 10-3 =7

Step-by-step explanation:

x + x = 152

Suppose four students miss an exam. They tell their instructor that they were carpooling to school together on the day of the ex

tia_tia [17]

Answer:

The probability they each indicate the same tire is $\frac{1}{64}=0.02$

Step-by-step explanation:

There will be 4 cases involved as there are 4 tires.

Probability of choosing front left tire is $\frac{1}{4}$ as there are a total of 4 tires and we need to choose 1.

Now, if all the four students chose the front left tire then the probability is the product of individual probabilities.

Therefore, probability that all 4 students chooses front left tire is:

$P(fl)=(\frac{1}{4})^4$

Similarly, the probabilities of choosing the remaining 3 tires by all the students would be:

$P(fr)=(\frac{1}{4})^4$ , $P(rl)=(\frac{1}{4})^4$ , $P(rr)=(\frac{1}{4})^4$

Therefore, the probability that they indicate the same tire is the sum of all these probabilities.

$P(\textrm{same tire by all})=P(fl)+P(fr)+P(rl)+P(rr)\\ P(\textrm{same tire by all})=(\frac{1}{4})^4\times 4\\ P(\textrm{same tire by all})=\frac{4}{4^4}=\frac{1}{4^3}=\frac{1}{64}=0.02$
