Answer:

x=20

Step-by-step explanation:

log3(4x+1) = 4

Raise each side to the base of 3

3^log3(4x+1) = 3^4

4x+1 = 3^4

4x+1 = 81

Subtract 1 from each side

4x+1-1 = 81-1

4x= 80

Divide by 4

4x/4 = 80/4

x = 20

Craig is practicing his baseball pitching he kept track of the speed of each of his throws yesterday,and made the histogram
Morgarella [4.7K]

Using it's concept, there is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

From the histogram, the number of pitches is given by:

1 + 5 + 3 + 4 + 1 + 2 = 16.

Of those, 2 were between 70 and 75 mph, hence the probability is given by:

p = 2/16 = 1/8 = 0.125.

There is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
