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)
Answer: It depends on the mean absolute deviation of Samantha.
Avi has a mean absolute deviation (MAD) of 5. That means the average distance of Avi's score from her mean is 5 points.
If Samantha has a higher MAD, that means that she is less consistent. If Samantha has a lower MAD, that means she is a more consistent scorer than Avi.
Y=-2 should be the answer
126/14=9
so the width of the rectangle is 9
=
(mixed fraction can be solve into simple fraction be multiplying denominator by the middle number then add the nominator. In this case, 3 x 2 + 1 = 7. 7 is the new nominator and denominator is same as mixed fraction.)
Thus,
(7/3) ÷ (1/2) = (7/3)(2/1) = 14/3
(when dividing fraction be fraction, you can change it to multiplication by flipping divisor)
Therefore, The simplest form would be 14/3
