Absolute Value is always positive.<br><br> True<br> False

kramer

Answer: False

Step-by-step explanation: Absolute value means <em>distance from zero</em> on a number line. A common mistake is to assume that absolute value is always positive but that's not necessarily the case.

Take 0 for example.

It's 0 units away from zero on a number line which

means it has an absolute value of zero.

However, all other numbers besides zero will have

an absolute value that is positive.

The mean cost for a pint of frozen yogurt is $1.50, with a standard deviation of $0.10.

djverab [1.8K]

Answer:

The correct answer is:

0.01$ (c)

Step-by-step explanation:

Standard deviation is a measure of how spread out numbers are from the mean value. The formula for standard deviation is given by:

$s = \sqrt{\frac{\sum(x - \bar x)}{n} } \\where:\\x = sample\ \\\bar x\ = mean\\n\ = number\ of\ samples\$

Variance is a measure of the squared differences from the mean.

Variance is simply the square of the standard deviation. It is mathematically shown as:

$s^2 = \frac{\sum(x - \bar x)}{n} }$

Now in our example,

Stabnard deviation = $0.10

Variance = (standard deviation)²

Variance = (0.10)²

Variance = $0.01

Find the exact area of the shaded please helppp ILL GIVE BRAINLIESTTTTTT

musickatia [10]

Answer:

The exact area is $5\pi$

Step-by-step explanation:

The area of the major circle is subtracted from the area of the minor circle (blank)

Major circle

$r=\frac{6}{2} =3$

$A=\pi r^{2} =\pi (3)^{2} =\pi (9)=9\pi$

Minor circle:

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

$A=\pi r^{2} =\pi (2)^{2} =\pi (4)=4\pi$

The shaded area:

$9\pi -4\pi =5\pi$

Hope this helps
