Answer:
DE = 6.3
Step-by-step explanation:
The length of the midsegment of a triangle is half the length of the side it is parallel to.
Side DE is parallel to side CA and side CA is 12.6.
12.6/2 = 6.3
DE = 6.3
110° because interior angles are half the measure of their arc

Since approximately 95% of any normal distribution falls within two standard deviations of the mean, it follows that 5% falls outside that range, with 2.5% to either side. So

.
The actual value is a bit closer to 0.0228, but that's not very far off.
It will take Mallory 40 minutes to get to the airport by train.
Step-by-step explanation:
Given,
Time taken by car = 120 minutes
Time taken by train = t
According to given statement;
Time taken by car = 3 times time taken by train

Dividing both sides by 3

It will take Mallory 40 minutes to get to the airport by train.
