Ok you would have to multiply the 11 by 3 then you should get your answer of 33m.
Answer:
B
Step-by-step explanation:
We are given the following values:
n = number of samples / cars = 1,698
p = probability of each success = 0.07
The standard deviation (σ) is calculated using the
formula:
σ = sqrt [n p (1 – p)]
σ = sqrt [1,698 (0.07) (1 – 0.07)]
σ = 10.51
The mean (x) is:
x = n p
x = 1,698 (0.07)
x = 118.86 car accidents
The quartiles are:
1st quartile = x - 2σ to x – σ
1st quartile = 118.86 – 2 (10.51) to 118.86 –
10.51
1st quartile = 97.84 to 108.35
(97.84<Q1<108.35)
3rd quartile = x to x + σ
3rd quartile = 118.86 to 118.86 + 10.51
3rd quartile = 118.86 to 129.37
(118.86<Q3<129.37)
Division would go first, then multiplication.
16 ÷ 8 = 2
2 × 243 = 486
Answer:
1 way -1 in each group
2 way- 3 in each group
3 way-2 in one group and 1 in another grop
