3. 8(3+8)
Explanation : 8x3 = 24 + 8x8 =64 which is congruent to 24 +64
6 and 30 camd be simplified with 6
the result will be 1:5
so the question mark is 5
Answer:
729015430.40641995 = 729015430.41
Step-by-step explanation:
Since the 3 decimal place is 6, you round up. If you round up for 0 you get 1. Therefore your answer is 729015430.41.
The percent of the parcels weighed between 12 ounces and 30 ounces will be 81.86%. And the percentage of the parcels weighing more than 42 ounces will be 0.13%
<h3>What is a normal distribution?</h3>
The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
During 1 week an overnight delivery company found that the weights of its parcels were normally distributed, with a mean of 24 ounces and a standard deviation of 6 ounces.
Then the percent of the parcels weighed between 12 ounces and 30 ounces will be
When x = 12, then we have
z = (12 - 24) / 6
z = -2
When x = 30, then we have
z = (30 - 24) / 6
z = 1
Then we have
P(12 < x < 30) = P(-2 < z < 1)
P(12 < x < 30) = 0.81859
P(12 < x < 30) = 81.86%
Then the percentage of the parcels weighing more than 42 ounces will be
When x = 42, then we have
z = (42 - 24) / 6
z = 3
Then we have
P(x > 42) = P(z > 3)
P(x > 42) = 1 - P(z < 3)
P(x > 42) = 0.0013499
P(x > 42) = 0.13%
