Answer:
1. h = 11 cm
2. d = 220 km
Step-by-step explanation:
1. A = 1/2bh
Where,
A = 66 cm²
b = 12 cm
A = 1/2bh
66 = 1/2 * 12 * h
66 = 6h
h = 66/6
h = 11 cm
2. s = d/t
Where,
s = 110 km/h
t = 2h
s = d/t
110 = d/2
Cross multiply
110 * 2 = d
d = 220 km
You would have 2/3 because 4 can go into the numerator 2 which makes the numerator of your answer 2, then 4 goes into 12 4 Times which makes the denominator of your answer which is 3 so 2/3
I can not be B that is for sure It is C hoped that helped

Based on the rules of statistics</span>
68% of the data falls within 1 standard deviation of the mean
95% of the data falls within 2 standard deviation of the mean
99% of the data falls within 3 standard deviation of the mean
20 falls between the range of -56 to 56 (from the given 95%)
Hence we accept the null hypothesis; else, if the mean falls outside the
range, we reject the null hypothesis.
