Answer:
13 , 17 and 25 cm.
Step-by-step explanation:
Let the length of the first side be x cm.
Then the second is x+4 and the third is 2x-1 cm long.
As the perimeter = 55 cm we have the equation:
x + x + 4 + 2x - 1 = 55
4x + 3 = 55
4x = 52
x = 13 cm.
Answer:
Because we don't know the exact shape of the population distribution since they are not Normally distributed and they are also not very non-Normal
Step-by-step explanation:
We are given;
Population standard deviation;μ = 200
Population standard deviation; σ = 35
Sample size; n = 30
We are told that the weights are not Normally distributed and they are also not very non-Normal. Therefore it means we don't know the exact shape of the population distribution and as such we can't calculate the probability that a randomly selected passenger weighs more than 200 pounds.
Answer:
.1
Step-by-step explanation:
Try and take it step by step.
-2.3 + 10.8 + (-8.4)
First let's rearrange and combine the negatives.
-2.3 + (-8.4) + 10.8
-2.3 + (-8.4) = - 10.7
Let's rewrite
10.8 - 10.7 and solve!
10.8 - 10.7 = .1
