Answer:

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 = 55%=0.55

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

=(0.55)^4\\=0.09150125

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%

How do you convert 60 miles per hour is how many feet per second? can iny one help
DiKsa [7]
That's two questions.

The answer to the second question is:  Yes.

The answer to the first question is:

Multiply 60 miles per hour by ' 1 ' a few times.  Use fractions that have
the same thing on top and bottom, since those are always equal to ' 1 '.
Then cancel units if the same unit is on the top and the bottom.
Here's how it goes:

(60 mi/hr) x (5280 ft/mile) x (1hr/3600 sec) = (60 x 5280 / 3600) ft/sec = <u>88 ft/sec</u>
