First distribute...

0.5x + 1.4 - x = 0.6 + 0.3

Then add your like terms...

-0.5x + 1.4 = 0.9

Solve like normal equation....

Find the volume of a cone with radius 10 feet and height of 4 feet.
Sveta_85 [38]

Answer:

\frac{400}{3} \pi

Step-by-step explanation:

Formula for Cone: πr^{2}\frac{h}{3}

Since we have all the components, we can find the volume of the cone.

R = 10

H = 4

π10^{2}\frac{4}{3}

10×10 = 100

100π}\frac{4}{3}

}\frac{4}{3}×100

4       100          400

---  ×   -----    =    ------

3          1              3

Answer: \frac{400}{3} \pi

Hope this helped.

As part of his semester project, a BYU-Idaho Introductory Statistics student calculates a 95% confidence interval for the true p
lyudmila [28]

Answer:

a. There's a 95% chance that the true proportion is in the confidence interval.

Step-by-step explanation:

When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.

Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.

When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.

The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
