Using the normal distribution relation, the probability that sample will exceed the weight limit is 0.004
<u>Using the relation</u> ::
The mean, μ = np = (162 × 19) = 3078
The standard deviation, σ = 28 × √19 = 122.049
<u>The Zscore</u> :
Zscore = (3401 - 3078) ÷ (122.049)
Zscore = 2.65
Hence,
P(Z > 2.65) = 1 - P(Z < 2.65)
Using a normal distribution table :
P(Z > 2.65) = 1 - 0.9959
P(Z > 2.65) = 0.004

B - 63 Degrees, obviously because all angles add up to a sum of 180 degrees.
X = 10
y = -2
x/y = 10/-2
x/y = -5
Hence, x/y = z
Answer:
12 times 2 since it doubles every time I'm not that sure so if I am not correct my bads
