Answer:

  9/16 inch

Step-by-step explanation:

A = 3/4 +1/16

B = 1/4

x = A - B

x = (3/4 +1/16) - (1/4) . . . an equation for the difference

x = (12/16 + 1/16) - 4/16 = (13 -4)/16

x = 9/16

The difference between A and B on the ruler is 9/16 inch.

this probability distribution shows the typical distribution of pitches thrown to a batter in a given at-bat in a baseball game.
Otrada [13]

Answer = 9/10

Explanation:

Add up all the frequencies along the bottom row: 15+20+40+15+10 = 100

There are 100 pitches total. Ten of which occurs when the pitcher throws 5 times at the batter, as shown in the far right-most column. This means 100-10 = 90 occurrences happen when the pitcher throws 4 or fewer pitches to the batter.

The probability your teacher wants is therefore 90/100 = 9/10. This answer is in fraction form. It is equivalent to the decimal form 0.9
