Question

(MEDALS!!!!!!!!) Please answer.

Jim finds that his experimental probability of striking out while at bat in a baseball game is 25%. Out of 160 times at bat, about how many times could he predict he will strike out?

One way to find the answer is to set up an equation. Multiply the probability by the number of times at bat.

25/100 • ______ = x

______ = x Solve for x.

Answer 1

40

Answer 2

Where's the other answee?

Answer 3

160 * .25 = 40

Answer 4

40 goes to both answers? on both lines?

Answer 5

dont need the bottom equation thing, the answer to the story problem is 40

Answer 6

Oh okay, will you help me on another one please?

Answer 7

sure

Answer 8

You can also set up a proportion to solve the problem.

25/100 = x/☐

25 • ________ = _________ • x

_________ = 100x

_________ = x

Answer 9

what exactly does the question ask?

Answer 10

The same question

Answer 11

you have to set 100x equal to something or you cant find x

Answer 12

Wat do u mean

Answer 13

100x = y
x = ____
you cant find x unless you have something in for y
like if y was 500
100x = 500
500 / 100 = 5
x would = 5

Answer 14

Wait, this is the wrong question.

It is impossible, unlikely, as likely as not, likely, or certain that during the next year Southern California will have another year with less than 17 days of rain?

Answer 17

then it's unlikely

Answer 18

THANKS. WAIT

Answer 19

How many years has it rained less than 17 days? _____________

How many years has it
rained more than 17 days? _____________

Since it has rained less than 17
days the same number of years that it has rained more than 17 days, it is _________________ that the next year will have less than 17 days.

Answer 20

5 years since 10 years ago. not enough info to tell how many years has it rained more than 17
