Answer:
0.9
Step-by-step explanation:
To find the mean temperature, we have to add all of the numbers together and divide that by the amount of numbers there are.
6 + 5 + 3 + -4 + 3 + -3 + 2 + -1 + -2 + 0 = 9
There are 10 numbers.
Our mean, or average, would be 9 / 10 = 0.9
Answer:
0.0970
Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)
0.0075187 + 0.0263157 + 0.0631578
= 0.0969922
= 0.0970
Answer:
x=2 , y = 1
Step-by-step explanation:
x + 2(2x-3) = 4
x+4x-6=4
5x-6=4
5x= 10
x=10/5
x=2
subs x=2 into x +2y=4
2+2y=4
2y=2
y=2/2
y=1
Answer:
Step-by-step explanation:
just put the number on top and what divides it on the bottom
Answer:
You have to substitute so the answer to b will be - 41/128
