Answer:

CF

Step-by-step explanation:

As\ we\ know\ that,\\The\ longest\ side\ in\ a\ triangle\ is\ the\ side\ opposite\ to\ the\ largest\ angle.\\Here\ in\ \triangle BCF,\\\angle B=52\\\angle C=65\\\angle F=63 [Angle\ Sum\ Property\ Of\ A\ Triangle]\\Hence,\\As\ we\ can\ observe\ that\ \angle C\ is\ the\ largest\ followed\ be\ \angle\ F\ and\ \angle B. \\BF\ is\ the\ longest side\ followed\ by\ BC\ and\ CF.\\Hence, \\BF>BC>CF\\Or,\\CF

In the United States, the mean birth weight for boys is 3.41 kg with a standard deviation of 0.55 kg. Assume that the distributi
lyudmila [28]

Answer:

The proportion of baby boys in the United States that are born with low birth weight is 0.0495.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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.

3.41 kg with a standard deviation of 0.55 kg.

This means that \mu = 3.41, \sigma = 0.55

What proportion of baby boys in the United States are born with low birth weight?

This is the pvalue of Z when X = 2.5. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{2.5 - 3.41}{0.55}

Z = -1.65

Z = -1.65 has a pvalue of 0.0495

The proportion of baby boys in the United States that are born with low birth weight is 0.0495.

What is the surface area of the cylinder? Express the answer in terms of Pi.
Tomtit [17]

Answer:

Second option: Surface area = 176*pi cm2

Step-by-step explanation:

The surface area of a cylinder is given by:

S = 2*pi*r^2 + 2*pi*r*h

Where r is the base radius and h is the height.

If we have that the diameter is 8 centimeters, the radius is 8/2 = 4 centimeters. So with r = 4 and h = 18, we have that the surface area is:

S = 2*pi*4^2 + 2*pi*4*18 = 176*pi cm2

So the answer is the second option.
