Answer:
2/4 or 1/2
Step-by-step explanation:
i used a numbers chart to break the numbers down.
Answer:
The proportion of infants with birth weights between 125 oz and 140 oz is 0.1359 = 13.59%.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

The proportion of infants with birth weights between 125 oz and 140 oz is
This is the pvalue of Z when X = 140 subtracted by the pvalue of Z when X = 125. So
X = 140



has a pvalue of 0.9772
X = 125



has a pvalue of 0.8413
0.9772 - 0.8413 = 0.1359
The proportion of infants with birth weights between 125 oz and 140 oz is 0.1359 = 13.59%.
Depends. All multiples of 400, you could have many different options. For example, 400 buses 1 kid on ea. 40 buses 10 kids on ea.
400x1=400
40x10=400
Just if the two numbers multiple to 400 it can be an answer
Answer:
-657
Step-by-step explanation:

Substituting the value of a and b

The value of 3a²-4ab-26² is -657
Answer:
Well, with the info I have been given I would say; The L.A of a cylinder is SA+=2(pi)(r)(h).
Step-by-step explanation:
SA=Surface Area
LA=Lateral Area
Pi=3.14
R=Radius
H=Height
V=Volume
LA=2*pi*r*h <-- finds the Lateral Area of a cylinder
SA=LA+2*base or SA=2*pi*r*h+2*pi*r^2<-- finds the Surface Area of a cylinder
V=pi*r^2*h<---- Finds volume of the cylinder
