Answer:
The answer is "Option C"
Step-by-step explanation:
- It is the hypothesis which would be opposed to just the null hypothesis, that is used in its testing.
- In this, we generally believed that the results derive from a particular effect with some superimposed variance of chance.
- It is nothing but an option in contrast to the null and its original test starts by considering its two hypotheses, that's why the only option C is correct.
Answer:
0.478
Step-by-step explanation:
divide - 11/20 = 0.478260869
not sure how many decimal places you need
At rate x miles/ hour drove d miles/ 4 hours;
At rate x-10 miles / hour drove d miles/5 h
d miles = x• 4 miles first rate
d miles= (x-10)•5 miles second rate
5x-50= 4x
5x-4x= 50
X= 50 miles/h to get to the beach
50-10= 40 miles/h to get home
Answer:
<u>System:</u>
- Equation 1: L = M - 5
- Equation 2: L + M = 45
Explanation:
Rewrite the question to delete the typos:
- Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was 31. Let l be Lindsay's age and let mmm be Mark's age.Which system of equations represents this situation?
<u>1. Name your variables:</u>
<u />
<u>2. Translate each verbal statement into an algebraic expression:</u>
a) Lindsay is 5 years younger than Mark
- L = M - 5 ← first equation
b) Seven years ago, the sum of their ages was 31
L + M - 14 = 31
L + M = 31 + 14
L + M = 45 ← second equation
<u>3. Write the two equations:</u>
System:
- Equation 1: L = M - 5
- Equation 2: L + M = 45
I think the answer is 78.53982
Hope it helps!
