A circle has a circumference of 33 inches. What is<br> the area of the circle?

UkoKoshka [18]

Answer: Circle

Solve for area

A≈86.66in²

C Circumference

Using the formulas

A=πr2

C=2πr

Solving forA

A=C2

4π=332

4·π≈86.65987in²

g The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 cus

vagabundo [1.1K]

Answer:

The right solution is "0.196".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1 \ minute$

Sample size,

$n=100$

Confidence level,

$c=95$ %

$=0.95$

Now,

For $\alpha=1-c$

$= 1-0.95$

$=0.05$

then,

$Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }$

$=Z_{0.025}$

$=1.96$

The margin or error will be:

⇒ $E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })$

On substituting the values, we get

= $1.96(\frac{1}{\sqrt{100} })$

= $1.96\times \frac{1}{10}$

= $0.196$

konstantin123 [22]

Answer:

The values is

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 2.45$

The standard deviation is $\sigma = 0.35 \ mi$

The random value is $x = 2.03$

The standardized score for a binding site position of 2.03 microns is mathematically represented as

$z-score = \frac{x - \mu}{ \sigma }$

=> $z-score = \frac{2.03 - 2.45}{ 0.35}$

=> $z-score = -1.2$
