The standard deviation is the square root of the variance

so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14

Answer:

14.

Step-by-step explanation:

It is given that the variance of the data values in a population is 196.

Population variance = \sigma ^2=196

We need to find the standard deviation of the data values.

Population standard deviation = \sigma

\text{Population standard deviation}=\sqrt{\text{Population variance}}

\sigma=\sqrt{196}

\sigma=14

Hence, the standard deviation of the data values is 14.

6 ft.<br> 12 ft.<br> 8 ft.<br> The area of this irregular<br> figure is<br> -sq. ft.<br> 16 ft.
nikdorinn [45]

Answer:

When we know all 3 sides, we use Heron's Formula

area = sqrt [s *(s-a) * (s-b) * (s-c)]

where "s" is the semi-perimeter which in this case equals

s = (6 + 8 + 12) / 2   = 13

area = sqrt [13 * 5 * 7 * 1]

area = sqrt 455

area = 21.3307290077

area = 21.33 square feet (rounded)

The sketches show the graphs y=-x^2+16 and y=7
Tanzania [10]

Answer:

7 = -x^2 +16

x^2 -16 = 7

x^2 -23 = 0

Using quadratic equation

x = -0 +- sqrt (23^2 - 4*1*23) / 2 * 1

x = sqrt (0 - -92) / 2

x = sqrt (92) / 2

x1 = 4.7958

x2 = -4.7958

Find the value of x in the triangle shown below.<br> Choose 1 answer:
Ad libitum [116K]

For the triangle, x is 12 units long.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The hypotenuse is the side which is the longest in the triangle and is always opposite the right angle.

In the given triangle, the hypotenuse is 13 units long. The other two sides measure 5 units and x units.

Step 2:

By substituting the known values, we get

13^{2} = 5^{2} + x^{2} .

x^{2} = 169 - 25 = 144.

x = 12.

Rounding this off to the nearest hundred, we get that x is 12 units long.

Which of the following is the greatest unit rate? *
Brrunno [24]

Answer:

It is the last one. (16 for 2 tickets)

Step-by-step explanation:

To make it a unit fraction you have to divide the denominator by itself to get 1. 2 divided by 2 equals 1. To keep the fraction equivalent divide the numerator by 2 as well. That equals 8. This makes the unit rate
