Answer:
144.9 <= x <= 145.5
Step-by-step explanation:
145.2 + 3 = 145.5
145.2 - 3 = 144.9
144.9 <= x <= 145.5
Answer:
Step-by-step explanation:
Find the value of the left hand side (LHS)
LHS = 1/4 // 5/6
LHS = 1/4 * 6/5
LHS = 6/20
LHS = 3/10
Now what will make 3/10 on the right?
B: 1/4 * 6/5 = 6/20 = 3/10
a = 4
b = 6
c = 5
Answer:
The probability is 0.508 = 50.8%.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.
This means that 
If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g.
This is 1 subtracted by the pvalue of Z when X = 0.8535. So
has a pvalue of 0.492
1 - 0.492 = 0.508
The probability is 0.508 = 50.8%.
Answer:
The answer is $420 dollars
Step-by-step explanation:
you times 560 by 25%
that comes to a total of 140/
Ms. Dawson's class raised 25 percent more so you would have to subtract 140 from 560
560-140=420
420 is how much Mr. Casey's class raised
Answer:
a. Life span increased
b. The median age could rise because of the improvement in medical technology. Also more advertisement of healthier life styles, such as eating healthy could have increase the median age.
c. No because this just shows the increase in life span not the decrease in children.
Step-by-step explanation:
a. more people on average lived longer lives. (explanation)
b. self explanatory I guess, my answer pretty much explained it.
c. life span of US citizens does not effect the children population. I guess you could say people lived longer lives to have more children, so possibly the number of children could have increased.
