Answer:
5/4 =x
7/4 =y
Step-by-step explanation:
We can use proportions to solve. Put the small triangle side over the big triangle side
5 8
---------- = -------------
5+x 10
Using cross products
5*10 = 8(5+x)
Distribute
50 = 40+8x
Subtract 40 from each side
50-40 =40-40+8x
10 = 8x
Divide by 8
10/8 = 8x/8
5/4 =x
7 8
---------- = -------------
7+y 10
Using cross products
7*10 = 8(7+y)
Distribute
70 = 56+8y
Subtract 56 from each side
70-56 =56-56+8y
14 = 8y
Divide by 8
14/8 = 8y/8
7/4 =y
Answer:
The z-statistic lies in the critical region
Step-by-step explanation:
When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:
- If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
- If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.
In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:
The z-statistic lies in the critical region

Answer:
Addition Property of Equality
Step-by-step explanation:
Given expression:
To find the missing justification.
We will evaluate the given expression and justify the step.
Using Addition Property of Equality( by this property of equality we can add a number to both sides of the equation without effecting the equality of the equation)
Adding to both sides of the equation.
First isolate 10x^2
10x^2 = 36y^2 + 100
Divide both sides by 10
x^2 = 3.6y^2 + 10
