Answer:
0.0351478382 (To be precise)
Step-by-step explanation: Can I get brainliest? Thanks
1. Normal Distribution --> Z ~ (0,1^2)
2. Use normalcdf(lower bound, upper bound, μ, σ) function on a graphing calculator
P(Z≥103.53) = normalcdf(103.53, 1e99 [default], 80, 13)
P(Z≥103.53) ≈ 0.03
3. μ+σ ≈ 13.59% According to Z-distribution chart
80+13=93
So about 93 exceed only the top 16% (estimated answer not exact)
9 games
You can get this by multiplying each percentage by the total number of games to see what they have to expect.
.55*180 = 99 games (red team)
.60*180 = 108 games (blue team)
Now subtract the blue team expectation from the red team.
108 - 99 = 9 games.
75/100 = 0.75
--------------------
12 x 0.75 = 9
* The mine elevator travels a
distance of 9 metres per minute.
---------------------
After 2 minutes, the mine elevator
would've travelled 18 metres,
therefore your answer is:
A: -18 metres
(688-684) x 222
You have to do what’s in the parentheses first because of PEMDAS
688-684=4
Then you have to multiply
4x222
=888
