66.48% of full-term babies are between 19 and 21 inches long at birth
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.
Mean length of 20.5 inches and a standard deviation of 0.90 inches.
This means that
What percentage of full-term babies are between 19 and 21 inches long at birth?
The proportion is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 19. Then
X = 21
has a p-value of 0.7123
X = 19
has a p-value of 0.0475
0.7123 - 0.0475 = 0.6648
0.6648*100% = 66.48%
66.48% of full-term babies are between 19 and 21 inches long at birth
First set change the function f(x) to y so
that it would be
Then set y = 0
Then solve for x
X = - 3
To graph it, just plot the point (-3,0) on the x-axis
that it would be
Then set y = 0
Then solve for x
X = - 3
To graph it, just plot the point (-3,0) on the x-axis
<em>What is the value of c in the quadratic </em>?
Before starting to solve, you should notice something - the
quadratic is not in its standard form!
We can easily fix it by adding on both sides:-
We can switch the order of 28 and -11x:-
Now, the quadratic is in its standard form, so we can get down to
finding the value of "c".
Remember, the standard form of a quadratic looks like so:-
Now we can just write our <u>quadratic</u> here:-
Now, can you see what the value of "c" is?
An easy way to <u>remember</u> "c" in quadratics is:-
The "c" in quadratics is the constant.
Henceforth, we conclude that the value of "c" in the given quadratic is:-
