Answer:
2x + 4
Step-by-step explanation:
Let R = Ralph's age
and x = Sarah's age
Then Ralph's age in 4 years = R + 4
and Sarah's age in four years = x + 4
Thus, R + 4 = 2(x + 4)
Distribute the 2 R + 4 = 2x + 8
Subtract 4 from each side R = 2x + 4
Ralph's age is 2x + 4.
Answer: hi your question is incomplete below is the complete question
answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Answer:
y = 1/4x - 1/2
Step-by-step explanation:
-4y = -x + 2 : Divide both sides by -4
y = 1/4x - 2/4 : Reduce to lowest terms
y = 1/4x - 1/2
Answer:
All of those expressions has the same value because the value of a equation in a expression is the number after the equals sign in an expression. The main reason though is because 20/0.5=(100/10)/(5/10) and 1/0.05=(10/10)/(0.5/10)
Step-by-step explanation:
Domain — x > 1 (I notice opened dot.)
Range — y > 1
