1 answer:

6 0

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=2\\ h=5 \end{cases}\implies V=\cfrac{\pi (2)^2(5)}{3} \\\\\\ V=\cfrac{20\pi }{3}\implies V\approx 20.94$

6. Solve this inequality: j/4 -8 < 4.

Vaselesa [24]

Answer:

Step-by-step explanation:

Given

$\frac{j}{4}$ - 8 < 4 ( add 8 to both sides )

$\frac{j}{4}$ < 12

Multiply both sides by 4 to clear the fraction

j < 48 → D

Answer:

no solution

Step-by-step explanation:

The equations are inconsistent. The set of equations reduces to ...

x + 2y + 3z = 12

x + 2y + 3z = 30

x + 2y + 3z = 60

No values of x, y, and z can satisfy all three equations. There is no solution.

Answer:

1. False; 2. False; 3. False.

Step-by-step explanation:

1. Mode

False.

The mode, mean, and media are all measures of central tendency.

The mean is the best measure for normally distributed data.

The median is the best measure for skewed data.

The mode is the least used, because it's the only measure you can apply to nominal data.

2. Median

False.

The mean is the average of a set of scores or list of numbers.

3. Frequency distribution table

False.

It is not necessary to put the numbers in order.

For example, assume that you wanted to count the frequency of occurrence of each number in the list: 3, 0, 1, 4, 4, 1, 2, 0, 2, 2, 0, 2, 0, 1, 3, 1, 2, 1, 1, 3.

If you are doing this manually, you would go through the list and use tally marks to record the appearance of each number in its category.

If you are using a computer, it will do the sorting for you.
