How many circles with a 3ft radius could fill a 100 square foot (10ft x 10ft) space without overlap?

Alborosie

Answer:

Step-by-step explanation:

Considering that the circle has radius of 3ft to mean its diameter is twice the radius hence 6 ft

Given that the length of the square is 10 ft

10÷6=1 ⅔ hence only 1 circle

10-6=4 ft

The space of 4ft can't allow another circle to fit without an overlap. Therefore, only one circle can fit

First add 5 to right side
$\frac{x}{7} = -4+5 = 1$
Next , to cancel the 7, you need to multiply by 7 on both sides
$x = 1*7 = 7$

A random sample of n = 8 E-glass fiber test specimens of a certain type yielded a sample mean interfacial shear yield stress of

ANTONII [103]

Answer:

$32.9-2.365\frac{4.9}{\sqrt{8}}=28.80$

$32.9+2.365\frac{4.9}{\sqrt{8}}=37.00$

Step-by-step explanation:

Information given

$\bar X=32.9$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s=4.9 represent the sample standard deviation

n=8 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

the degrees of freedom are given by:

$df=n-1=8-1=7$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and the critical value for this cae would be $t_{\alpha/2}=2.365$

Now we have everything in order to replace into formula (1):

$32.9-2.365\frac{4.9}{\sqrt{8}}=28.80$

$32.9+2.365\frac{4.9}{\sqrt{8}}=37.00$
