Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04
To find the mean, you need to find the average. The equation that I used was 61(1)+64(3)+67(5)+70(6)+73(5) and then divided that total by the total number of 20.
The answer would be D) 68.5
The probability that a flight that departs on schedule also arrives on schedule
83%×68%=56%
Answer:
10x + 6y
Step-by-step explanation:
Let t = length of the third side
3x + 4y + 5x - y + t = 18x + 9y
8x + 3y + t = 18x + 9y
t = 10x + 6y
Answer:
Yes
Step-by-step explanation:
4/4 is the same thing as 4 divided by 4 which equals 1
7/8 is the same thing as 7 divided by 8 which equals 0.875
Since 1 > 0.875, 4/4 > 7/8
