0.5 inches a month.

I believe you subtract 13 1/4 by 10 3/4 = 2 1/2.

In a certain Algebra 2 class of 29 students, 7 of them play basketball and 14 of them
Mariulka [41]

Answer:

<em>Two possible answers below</em>

Step-by-step explanation:

<u>Probability and Sets</u>

We are given two sets: Students that play basketball and students that play baseball.

It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.

This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:

\displaystyle P=\frac{19}{29}

P = 0.66

Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:

We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.

Thus, there 19-2=17 students who play only one of the sports. The probability is:

\displaystyle P=\frac{17}{29}

P = 0.59

PLEASE HURRY WILL MARK BRAINIEST THIS IS AN EASY QUESTION
viva [34]

first qn

4/36=1/9

total no. of ways to roll a dice=36

no. of ways to produce 7=3

(1+6=7, 2+5=7, 3+4=7)

no. of ways to produce 11=1

(5+6=11)

there are 4 ways in total. 4/36 simplify it to be 1/9

second qn im not sure but i think its

1/9 x 50 = 50/9 = 5 x (5/9)

round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
