How to make an improper fraction into a proper fraction?

Mathematics

e-lub [12.9K]3 years ago
7 0
Divide the numerator by the denominator and any remaining values go back above the denominator. 

Example: 

17 / 4 is an improper fraction. To turn it into a proper fraction we do 17 divided by 4. 

17 / 4 is 4 with a remainder of 4. So we put the 4 on the outside and the 1 back above the denominator, which is 4. 

It ends up looking like this: \frac{17}{4} = 4 \frac{1}{4}

The table shows the results of a biologist who captures and tags lake trout, and then sets them free. What is the trout populati
zloy xaker [14]

Answer:

A.) About 90

Step-by-step explanation:

From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.

Thus, let the trout population in the lake be represented by x,

    \frac{60}{100} =  \frac{x}{150}

Cross multiply to have;

 100 × x = 60 × 150

  100x = 9000

Divide both sides by 100,

 x = \frac{9000}{100}

    = 90

Therefore, the trout population is about 90 in the lake.

Let μ denote the true average radioactivity level(picocuries per liter). The value 5 pCi/L is considered thedividing line betwee
VMariaS [17]

Answer:

H0: μ = 5 versus Ha: μ < 5.

Step-by-step explanation:

Given:

μ = true average radioactivity level(picocuries per liter)

5 pCi/L = dividing line between safe and unsafe water

The recommended test here is to test the null hypothesis, H0: μ = 5 against the alternative hypothesis Ha: μ < 5.

A type I error, is an error where the null hypothesis, H0 is rejected when it is true.

We know type I error can be controlled, so safer option which is to test H0: μ = 5 vs Ha: μ < 5 is recommended.

Here, a type I error involves declaring the water is safe when it is not safe. A test which ensures that this error is highly unlikely is desirable because this is a very serious error. We prefer that the most serious error be a type I error because it can be explicitly controlled.

the slide at the playground has a height of 6 feet.The base of the slide measured on the ground is 8 feet.what is the length of
NemiM [27]
The formula for finding the length is
{a}^{2}  +  {b}^{2} = {c}^{2}
All we have to do is plug in the numbers.

{6}^{2}  +  {8}^{2}  =  {c}^{2}
36 + 64 = 100

Since 100 =
{c}^{2}
we have to find the square root.

\sqrt{100}  = 10

The length of the slide is 10 feet.
