Calculate the area and the circumference of the circle

tiny-mole [99]

Circumference = 2 x radius x Pi

Circumference = 2 x 0.8 x pi

Circumference = 1.6pi or 5.024 yards

area = r^2 x pi

Area = 0.8^2 x pi

Area = 0.64pi or 2.0096 square yards

The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.

Pie

Answer:

$Area = 270m^2$

Step-by-step explanation:

Given

$A = \frac{1}{2}bh$

$b = 18m$

$h = 30m$

Required

Solve for A

Simply substitute 18 for b and 30 for h

$A = \frac{1}{2}bh$

$A = \frac{1}{2} * 18 * 30$

$A = 270$

Hence:

The area is

$Area = 270m^2$

Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence i

mash [69]

Complete Question

A biologist reports a confidence interval of (3.5,4.9) when estimating the mean height (in centimeters) of a sample of seedlings. What is the estimated margin of error and the sample mean?

Answer:

The margin of error is $E = 0.7$

The sample mean is $\= x = 4.2$

Step-by-step explanation:

from the question we are told that

The upper limit is $k = 4.9$

The lower limit is $r = 3.5$

Generally the margin of error is mathematically represented as

$E = \frac{k - r}{ 2}$

$E = \frac{ 4.9 - 3.5 }{2}$

$E = 0.7$

Generally the sample mean is mathematically evaluated as

$\= x = k - E$

=> $\= x = 4.9 - 0.7$

=> $\= x = 4.2$

How do you find the intersection of two sets?

Vlad [161]

To find the intersection of these two sets, we need to find out what elements they have in common. The numbers 3, 4, 5 are elements of both sets, therefore theintersections of A and B is {3. 4. 5].
