Answer:
0.8151 is the probability that the weight will be less than 4293 grams.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 4004 grams
Variance = 103,684
We are given that the distribution of weight of newborn baby is a bell shaped distribution that is a normal distribution.
Formula:
P(weight will be less than 4293 grams)
P(x < 4293)
Calculation the value from standard normal z table, we have,
0.8151 is the probability that the weight will be less than 4293 grams.
Answer:
0
Step-by-step explanation:
Answer:
the radius must equal 2
Step-by-step explanation:
A = pi * r^2 C = 2 * pi *r
set them equal
pi * r^2 = 2 * pi *r
divide both sides by pi
r^2 = 2 * r
divide both sides by r
r^2 /r = 2r/r
r = 2
A. 10 boys to 12 girls because both numbers in the given ratio have been multiplied by two 5*2=10 6*2=12. None of the other options can be simplified to the original given ratio of 5:6.
Answer:
53.62 m
Step-by-step explanation:
Length of arc = θ/360 × 2πr
r = XZ = 12 m
m<XYZ = 180 - 108 = 72° (angles on a straight line)
θ = 85° + 72° + 108° = 265°
Length of arc YWV = 256/360 × 2 × π × 12
= 53.6165146 ≈ 53.62 m (nearest hundredth)
