Whats another way to write 300 70 5/10 8/100?

2 answers:

8 0

I don't understand what you mean by 300 and 70, unless you meant 300/70 (in that case it would be 30/7).

5/10 would be 1/5

8/100 would be 2/25.

Hello!

There are many other ways you can write these fractions. They are called "equivalent fractions".

Equivalent fractions mean the same thing as other fractions. You can get an equivalent fraction by either multiplying or dividing the numerator and the denominator of the fraction by the SAME number.

300/70 ÷ 10 = 30/7

So, 300/70 is equivalent to 30/7. You can also multiply by, say, 2.

300 × 2 = 600

70 × 2 = 140

So, 600/140 is also another fraction that is equivalent to 300/70.

5/10 is equivalent to 10/20, 15/30, 20/40, and many more fractions.

8/100 is equivalent to 4/50, 2/25, etc.

A kennel has 80 dogs in total dogs in total, some are puppies and some are adult dogs. The ratio of puppies to adult dogs in a k

aleksklad [387]

The ratio given says this - 3 puppies : 2 adults = 5 total dogs
You are given (?) puppies : (?) adults = 80 total dogs
In this case, you are trying to find the number of puppies, so you do not need to care about the number of adults. You need to compare the ratio with the actual amount.
Total/puppies = total/puppies
5/3 = 80/(?)
Now, cross multiply.
5(?) = 240
Divide both sides by 5 and you get your answer.
(?) = 48

Simplify the expression.<br><br> (−5g5h6)2(g4h2)4

Colt1911 [192]

We have to simplify the expression here. The expression given,

$(-5g^5h^6)^2(g^4h^2)^4$

Now to find $(-5g^5h^6)^2$ we will use power of a product property. We have to distribute the power here. We will get,

$(-5g^5h^6)^2 = (-5)^2(g^5)^2(h^6)^2$

= $25(g^5)^2(h^6)^2$

Now we will use power of a power property. If given $(a^m)^n$ we will have to multtiply the powers and we will get $a^{mn}$ . So we will get here,

$25(g^5)^2(h^6)^2 = 25 g^{10} h^{12}$

Now the next part is $(g^4h^2)^4$

By using power of a power property we will get,

$(g^4)^4(h^2)^4 = g^{16}h^8$

Now we have to multiply them.

$(25g^{10}h^{12} )(g^{16}h^8)$

Now we have to use product of powers property. If we have same base them we will have to add the exponents there. The formula is $(a^m)(a^n) = a^{(m+n)}$ . So we will get here,

$25(g^{10} g^{16})(h^{12} h^{8})$

$25g^{(10+16)} h^{(12+8)}$

$25g^{26}h^{20}$

So we have got the required simplified answer here.

The simplified answer is $25g^{26}h^{20}$ .

A veterinary study of horses looked water sources for horses and the investigators found that horses received water from either

Irina18 [472]

Answer:

d. Water Source Well City Water Stream Expected Count 45.33 45.33 45.33

Step-by-step explanation:

Hello!

The objective of this study is to test whether the horses are equally likely to get water from one of three sources (Well, City or Stream), i.e. that the water sources have the same probability of being used.

The study variable is categorical:

X: Origin of the drinking water of the horses, categorized: Well "W", City "C" and Stream "S"

And one study population:

"Horses"

If the study hypothesis is that the three water sources are equally to be selected, you can symbolize it as P(W)=P(C)=P(S)=1/3

You want to test if the observed distribution follows an expected distribution, the test to use is a Chi-Square Goodness of Fit Test.

The hypothesis is:

H₀: P(W)=P(C)=P(S)=1/3

Under the null hypothesis, the formula to calculate the expected frequencies is:

$e_{i}= n * P_{i}$

Where:

$e_{i}$ is the expected value of the i-category.

$P_{i}$ is the probability for the i-category under the null hypothesis.

n= sample size.

Observed frequencies:

Well: 62

City: 43

Stream: 31

Total: 136

Expected frequencies:

$e_{W}= n * P_{W} = 136*1/3 = 45.33$

$e_{C}= n * P_{C}= 136 * 1/3= 45.33$

$e_{S}= n * P_{S}= 136 * 1/3= 45.33$

Typ, if the expected frequencies are correctly calculated, the sum of them must give the total of the sample (although depending on the type of approximation it can vary in one or two decimals)

45.33 * 3= 135.99 ≅ 136

I hope it helps!
