Basketball player who ordinarily makes about 55% of his free throw shots has made 4 in a row. is this evidence that he has a "hot hand" tonight? that is, is this streak so unusual that it means the probability he makes a shot must have changed? expla

Step-by-step explanation:

Given that a basketball player who ordinarily makes about 55% of his free throw shots has made 4 in a row.

Probability for a success in any random throw =

Since each throw is independent no of successive throws is binomial with

p = 0.55 and q = 0.45

Probability his free throw shots has made 4 in a row

= Prob that continuous succesees in 4 throws

=

which shows that this is a very rare event with 0.55 for each success.

Hence this is unusual and there is a necessity to increase 0.55 or 55%

answer: options?

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
