Which of the following is not an integer?

In-s [12.5K]

Answer:

$-\frac{54}{7}$

Step-by-step explanation:

The first number is $\sqrt{\frac{64}{4} }$

We simplify to get: $\sqrt{\frac{64}{4} }=\sqrt{16}=4$

The second number is $-\frac{54}{7}$ .

This number can be rewritten as $7 \frac{5}{7}=7.714285714287$

This is not an integer

The third number is $(\frac{-25}{5})^2$

We simplify to get: $(\frac{-25}{5})^2=(-5)^2=25$

This is also an integer.

The correct answer is $-\frac{54}{7}$ .

Use the relative frequency approach to estimate the probability of the event. In a certain class of students, there are 8 boys f

In-s [12.5K]

Answer:

$P\text{Student will be from Kenilworth}\approx 0.256$

Step-by-step explanation:

We have been given that that there are 8 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 5 boys from Glencoe, 5 boys from Kenilworth and 7 girls from Glenoce.

The total number of students from Kenilworth is 5 boys plus 5 girls that is 10 students.

The total number of students in the class would be $8+5+9+5+5+7=39$

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

$P\text{Student will be from Kenilworth}=\frac{\text{Number of student from Kenilworth}}{\text{Total number of students}}$

$P\text{Student will be from Kenilworth}=\frac{10}{39}$

$P\text{Student will be from Kenilworth}=0.2564102564$

$P\text{Student will be from Kenilworth}\approx 0.256$

Therefore, the probability, that the student will be from Kenilworth, is approximately 0.256.
