Hi there!

So, in order to solve this equation, you would need to plug in the value of the appropriate variable.

6a/c - 2
6*12/2 - 2

Now, you would need to simplify the values on top of the fraction and solve.

72/2 - 2
36 - 2
34

Therefore, our final answer would be 34.

Does anyone know how to solve this? Thanks!

In an all boys school, the heights of the student body are normally distributed with a mean of 71 inches and a standard deviatio

muminat

Answer:

15.87%

Step-by-step explanation:

First thing here is that we calculate the z-score which corresponds to 76

mathematically;

z-score = (x-mean)/SD

mean = 71 and SD = 5

plugging these values, we have;

z = (76-71)/5 = 5/5 = 1

Now, we want to firstly get the probability that we have a student shorter than 76 inches

The probability we want to calculate is P(z<1)

we can get this using the z-score table directly

That would be 0.15866

In percentage that is 15.866% which is 15.87% to the nearest tenth

A fraction is less than 1. Choose a counterexample that will prove this conjecture false

Vesnalui [34]

Answer:

1st option

Step-by-step explanation:

Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.

1) $\frac{8}{7} = 1 \frac{1}{7}$

This fraction is greater than 1 hence it can prove that the conjecture is false.

2) ½ is lesser than 1 and will not prove that the conjecture is false.
