Answer: 12
Step-by-step explanation: If it was 60km in 1 hour it would 6 but since its half an hour just double the 6.
8/10*100=80%
-80% of the words were spelled correctly.
remember, whenever u get a challenge like this, always to multiply the given fraction by 100 (as stated above)
-hope it gives u an brief idea how to solve questions like these:)
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:
17%
Step-by-step explanation:
99.45-85=14.45
14.45/85= 0.17
0.17= 17%
