Answer:
Took the test, answer is C) 17(100)+17(40)+17(4)
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
Answer:
18
Step-by-step explanation:
Given the above table of the data set, the number of values less than or equal to 6 would be the sum of the frequencies of all values that is equal to or less than 6.

Answer:
a. (b) 2.5
b. (b) 1.89
Step-by-step explanation:
E(X) =0(0.05)+1(0.25)+2(0.35)+3(0.15)+4(0.15)+5(0.15)= 2.5
It has two pairs of same angles: that means that the opposite sides are parallel: this makes it a parallelogram.
