Answer:In its decimal form, it says ' 64 / 100 '.

In order to change it to its lowest terms, we look to see whether the

numerator and denominator have a common factor greater than ' 1 '.

If they do, then we can divide numerator and denominator by their

common factor, and have the same fraction in lower terms.

The common factors of 64 and 100 are 1, 2, and 4 .

We could divide top and bottom by 2, but that wouldn't finish the job.

It's always best to divide them by their greatest common factor, and

once you do that, you're done.

Dividing the numerator and denominator both by 4,

we get the fraction in its lowest terms:

0.64 = 64/100 = 16/25

Chris is working on a stained-glass project and needs to form a triangle with sides of 8, 12, and 15 inches out of lead cane to

Slav-nsk [51]

Answer:

The largest angle needed is $95.1^{o}$ .

Step-by-step explanation:

To determine the larges angle as required, let us apply the cosine rule.

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2ab Cos C

Since in triangles, the longest side is opposite to the largest angle, then;

$15^{2}$ = $8^{2}$ + $12^{2}$ - 2(8 x 12) Cos θ

225 = 64 + 144 - 192 Cos θ

225 = 208 - 192 Cos θ

192 Cos θ = 208 -225

192 Cos θ = -17

Cos θ = $\frac{-17}{192}$

Cos θ = -0.08854

θ = $Cos^{-1}$ -0.08854

= 95.07962

θ = $95.1^{o}$

The largest angle needed is $95.1^{o}$ .

A survey was taken of 49 people to see if they watch basketball and/or soccer games on television. The results are shown in the

emmasim [6.3K]

Answer:

$\begin{array}{cccc}&\text{Watch basketball}&\text{Don't watch basketball}&\text{Total}\\\text{Watch soccer}&7&12&19\\\text{Don't watch soccer}&17&13&30\\\text{Total}&24&25&49\end{array}$

Step-by-step explanation:

From the diagram you can see that

17 people watch only basketball;
7 people watch both basketball and soccer;
12 people watch only soccer;
in total, 17+7+12=36 people watch some sports;
so, 49-36=13 people do not watch sports.

So, you can fill the table in following way

$\begin{array}{cccc}&\text{Watch basketball}&\text{Don't watch basketball}&\text{Total}\\\text{Watch soccer}&7&12&19\\\text{Don't watch soccer}&17&13&30\\\text{Total}&24&25&49\end{array}$

I do not understand any of the questions its asking :c

Agata [3.3K]

Answer:

Step-by-step explanation:

The total number of students is 350 + 50 + 225 + 375 = 1000.

There are 225 students in band only, as well as 50 students in both band and choir. So there are 275 students in band out of the total of 1000, or 27.5%.

There are 350 students in choir only, as well as 50 students in both choir and band. So there are 400 students in choir, 50 of whom are also in band. So the probability is 50/400, or 12.5%.

The probabilities are not the same.

Since the probabilities are not the same, the probability of being in band is affected by whether or not the student is in choir. So the events are not independent.
