Find the volume of a cylinder with diameter 8 inches and height 9 1/2 inches
marta [7]

Answer:

V=152\pi in^{2} in terms or pi

V=477.52in^{2} simplified

Step-by-step explanation:

To solve this, we are using the Cylinder's volume formula:

V=\pi r^{2} h

where

V is the volume of the cylinder

r is the radius of the cylinder

Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius: r=\frac{d}{2} =\frac{8in}{2} =4in. Now, 9 1/2 inches is 9 and a half inches, so h=9.5in.

Replacing values:

V=\pi (4in)^{2} (9.5in)

V=\pi (16in^{2})(9.5in)

V=152\pi in^{2}

V=477.52in^{2}

We can conclude that the volume of our cylinder is V=152\pi in^{2} in terms of pi, or V=477.52in^{2} simplified.

The lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of
valina [46]

Answer:

(221.39, 300.61) and (255.2223, 266.7777)

Step-by-step explanation:

Given that X, the  lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of 17 days

Middle 98% would lie on either side of the mean with probability ±2.33 in the std normal distribution on either side of 0

Corresponding we have x scores as

Between 261-2.33*17 and 261+2.33*17

i.e. in the interval = (221.39, 300.61)

If sample size = 47, then std error of sample would be

\frac{17}{\sqrt{47} }

So 98% of pregnancies would lie between

261-2.33*\frac{17}{\sqrt{47} } and 262+2.33*\frac{17}{\sqrt{47} }

= (255.2223, 266.7777)

PLEASE HELP, DUE SOON !!
nydimaria [60]

Answer:

-0

Step-by-step explanation:

W = -3

X = 3

Z = -9

Y = 6

-3 + 3 = 0

-9 + 6 = -3

-3 + 0 = -3

Then -3 is closest to -0! Cause when rounding, 4 and under as an example as 24 the round will be 20! And 25 will be 30

How are fractions and decimals related
Airida [17]
A fraction is a short way to write a division problem. When you see a fraction, it means "the top number divided by the bottom number". When you actually DO the division, the answer is the decimal that's equal to the fraction.
