Answer:

Step-by-step explanation:
The standard form:

A, B and C are the integer.
We have:

Find the common denomintaor of given fractions.
We have 5, 4 and 2. The common denominator of 2, 4 and 5 is 20.
20 = 2 · 10 = 4 · 5 = 5 · 4
Thereofre multiply both sides by 20:

Answer:
D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Step-by-step explanation:
In statistics, type I error is when we reject the null hypothesis even when it is true.
Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.
This means that a type I error will be;
Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
2 x 10000 = 20000
2 x 10 x 10 x 10 x 10
The answer is 2 x 10^4
From the given equation
105% * 90 = 200% * x
105/100 * 90 = 200/100 * x
105*90 = 200*x
x = 105*90/200
X = 21*9/4
X = 189/4
x = 47.25
Value of x = 47.25 or 47 1/4
