So you know that 11 U.S. Dollars can be exchanged for 10 Euros which is 10/11. To figure out how many Euros you will receive for 1 Dollor you have to find the unit rate. To do this divide 10 by 11. The answer is 0.90
The data are reported in the attached table.
We define the null hypothesis H₀ as the statement that is believed true until we prove it wrong with the test.
We define the alternative hypothesis H₁ as the statement we want to conclude with our test.
The difference in graffiti before (B) and after (A) will be:
d = A - B.
If the graffiti declined, it means that A will be smaller than B, therefore d should be negative.
Therefore we can set:
H₀ : μd ≥ 0
H₁ : μd < 0
The equal sign would mean that the number of graffiti incidents remained constant, therefore it is part of the null hypothesis.
Therefore the correct answer is B) H₀: μd ≥ 0 versus <span>H₁</span>: μd < 0
Answer:
Step-by-step explanation:
<u>Simplify the expression:</u>
- 4(3b) – 2(3b + 1) =
- 12b - 6b - 2 =
- 6b - 2
Correct choice is D
Take the formula: y=mx+b
m= slope
b=y-intercept
m=2
b=-1
therefore:
y=2x-1
Well first u need 2 divide 20/348 Because u need to fiend HOW MANY U NEED so that means you need to divide And that's how many Tiles
