Calculate the area of a circle with a diameter of 12 cm

rosijanka [135]

we know its diameter is 12, thus its radius must be half that, or 6.

$\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies A=\pi 6^2\implies A=36\pi \implies A\approx 113.097$

William bought 5 rulers for $7.50. If r represents the cost of one ruler, which equation represents this situation?

kkurt [141]

So: 162...120%

x.... 100%

120x = 16200 => x = 135

Determine the point estimate of the population mean for the confidence interval of (15, 32). Enter up to 1 decimal place. Point

netineya [11]

Answer:

The point estimate of the population mean for the confidence interval of (15,32) is 23.5

Step-by-step explanation:

We are given the following information in the question:

Confidence interval for population mean is (15, 32).

We have to find the point estimate for population mean.

Formula:

$\mu = \displaystyle\frac{\mu_1+\mu_2}{2} = \frac{15+32}{2} = 23.5$

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5

Can someone help me<br> 7 + 2h = 3 + 4h

STALIN [3.7K]

h = 2

$7 + 2h = 3 + 4h$

You must isolate the variable to solve using the order of operations, or PEMDAS.

$4 = 2h$

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

$\frac{4}{2} = h$

Divide both sides of the equation by 2.

$h = 2$
