$2 \frac{3}{4} * \frac{4}{5}$ is the same as $\frac{11}{4} * \frac{4}{5}$ . The 4s will cancel leaving you with $\frac{11}{5}$ or $2 \frac{1}{5}$ , your 3rd option.

Answer:

Step-by-step explanation:

To be on the swim team, we look at the right most (total) number int he table of "on the swim team" row. That is 28.

The grand total is the bottom-rightmost. That is 67.

Hence, probability of being on swim team is 28/67 = 41.79%

The mean height of the basketball players is 80.3 inches

For given question,

we have been given the list of heights, in inches, for a sample of college basketball players.

We need to find the mean height of the basketball players.

We know that, for given sample of data

mean = sum of all observations ÷ total number of observation

First we find the sum of given heights.

78 + 83 + 82 + 78 + 78 + 80+ 81 +79+ 79 +83+ 77 +78+ 84+ 82+ 80+ 80 +82+ 84+78+ 80 = 1606

Total number of observations = 20

Using the formula of mean,

⇒ mean height = 1606/20

⇒ mean height = 80.3 inches

Therefore, the mean height of the basketball players is 80.3 inches

An OSU senior is studying for exams in psychology and economics. The student has time to read 50 pages of psychology and 10 page

cestrela7 [59]

Answer:

3 Pages

Step-by-step explanation:

Let the pages of economics read = e
Let the pages of psychology read = p
Let the total time taken on each instance=t

In the first instance, the student has time to read 50 pages of psychology and 10 pages of economics.

t=50p+10e

The student could read 30 pages of psychology and 70 pages of economics.

t=30p+70e

Since the two situations take the same amount of time, we have:

50p+10e=30p+70e

Collect like terms

50p-30p=70e-10e

20p=60e

Divide both sides by 20

p=3e

Therefore, in the time it will take the student to read 1 page of psychology, the student can read 3 pages of economics.

Find the missing side. Round to the nearest tenth when necessary.

777dan777 [17]

Use Pythagorean theorem
a^2 + b^2 = c^2
a = 9, b = x, c = 18
9^2 + x^2 = 18^2
81 + x^2 = 324
x^2 = 243
x = 15.58846
Round to nearest tenth
Solution: x = 15.6
