A baseball pitcher threw 3688 pitches during part of a recent season. Of these, 1166 were thrown with no strikes on the batter, 848 were thrown with one strike, and 1674 were thrown with two strikes. What is the probability that a baseball pitch is thrown with no strikes? Round your answer to four decimal places.

0.3162 = 31.62% probability that a baseball pitch is thrown with no strikes

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

Desired outcomes:

Pitches thrown with no strikes.

There were 1166 pitches thrown with no strikes, so

Total outcomes:

All pitches.

3688 pitches were thrown, so

Probability:

0.3162 = 31.62% probability that a baseball pitch is thrown with no strikes

dude thats to long figure it

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
