Complete question :
The birthweight of newborn babies is Normally distributed with a mean of 3.96 kg and a standard deviation of 0.53 kg. Find the probability that an SRS of 36 babies will have an average birthweight of over 3.9 kg. Write your answer as a decimal. Round your answer to two places after the decimal
Answer:
0.75151
Step-by-step explanation:
Given that :
Mean weight (m) = 3.96kg
Standard deviation (σ) = 0.53kg
Sample size (n) = 36
Probability of average weight over 3.9
P(x > 3.9)
Using the z relation :
Zscore = (x - m) / (σ / √n)
Zscore = (3.9 - 3.96) / (0.53 / √36)
Zscore = - 0.06 / 0.0883333
Zscore = −0.679245
Using the Z probability calculator :
P(Z > - 0.679245) = 0.75151
= 0.75151
Answer:2 and 4 and 1 and three because there in the same corners
Step-by-step explanation: 2 and 4 are in open corners while 3 and 1 are in closed corners
Answer:
10 3/4, 4 3/4, and 9 1/2
Step-by-step explanation:
We're going to let x represent the length of the longest side. The perimeter is
x +(x-6) +2(x-6) = 25
4x -18 = 25
4x = 43
x = 43/4 = 10 3/4
Then x-6 = 4 3/4.
Multiply that two to get 8 3/2 = 9 1/2
I hope this helped! :)
Answer:
25
Step-by-step explanation:
X² = 7² + 24²
X² = 49 + 576
X² = 625
X = 25
