Given that with a height of 63 in, Johnson was the shortest president of a particular club in the past century.
a) Positive difference between Johnson’s height and the mean=|63-66.5|=3.5 inches
b) No of std deviation the difference has =
c) Z score = no of std deviations from the mean = -2.692
d) Usual heights lie between -2 and 2. Hence Johnson’s height is unusual
Answer:
The cost of each slice of pizza is $ 14.5
Step-by-step explanation:
Given as :
The combined total of 2 slices and 1 drink cost = $ 31.50
The price of each drink = $ 2.50
Let The number of slices = S
The number of drink = D
According to question
2 × S + 1 × D = $ 31.50
∵ 1 drink cost $ 2.50
So, 2 × S + 1 × D = $ 31.50
Or, 2 × S + 1 × $ 2.50 = $ 31.50
Or, 2 × S = $ 31.50 - $ 2.50
Or , 2 × S = $ 29
∴ S = = $ 14.5
Hence The cost of each slice of pizza is $ 14.5 Answer
Answer:
The probability that a vehicle would be involved in a tire-related accident is
Step-by-step explanation:
We need to calculate the probability that a vehicule would be involved in a tire-related accident.
We know that, given a tire-related accident (TRA), the probability of it being deadly (D) is 0.05. That is:
We also know that the probability of being involved in a deadly tire-related accident is 0.000004
. We can express that as the probability of having a TRA multiplied by the probability of it being deadly:
Merging the two expressions we have:
