A family goes grocery shopping every week. in a month the costs of the groceries are $72.42, $91.50, $58.99, and $69.02. 5. what
frozen [14]
1) Mean
The mean is given by the sum of the data divided by the number of data (4, in this case):
\mu =   \frac{1}{N} \sum x_i = \frac{1}{4}(72.42+91.50+58.99+69.02) = \frac{291.93}{4}=72.98 $

2) Standard deviation
The standard deviation is given by:
\sigma =  \sqrt{ \frac{1}{N} \sum (x_i-\mu)^2 }
where \mu is the mean, that we already found at point 1), and N=4. Substituting data, we have:
\sigma =  \sqrt{ \frac{1}{4} ((-0.56)^2+(18.52)^2+(-13.99)^2+(-3.96)^2) } =
= \sqrt{ \frac{1}{4}  (554.71)} = \sqrt{138.68} =11.78 $

Solve for x. Round your answer to the nearest thousandth.
pogonyaev

Answer:

7.08

Choice A

Step-by-step explanation:

From the right-angled triangle we have been given the following;

One angle - 33 degrees

The hypotenuse - 13 units

We are required to determine the length of the side, opposite the angle, marked x.

Using the Mnemonic; SOHCAHTOA

The sine of an angle is; (opposite side)/(hypotenuse)

Therefore;

sin 33 = x/13

x = 13 * sin 33

x = 7.080
