Answer:

Mean = 2.95

Median = 3

Step-by-step explanation:

The mean of the number of visits of 40 adults to the gym is

$\dfrac{0\cdot 4+1\cdot 3+2\cdot 12+3\cdot 5+4\cdot 8+5\cdot 5+6\cdot 2+7\cdot 1}{40}=\\ \\=\dfrac{3+24+15+32+25+12+7}{40}=\dfrac{118}{40}=2.95$

The median of the data is the average number between 20th and 21th terms (because 40 is even number, so the middle term is the average between two middle terms).

20th term = 3 visits

21th term = 3 visits

Hence, median is 3 visits

Answer:

9,240

Step-by-step explanation:

For the first number, there are 22 numbers available to choose from. For the second number, there are 21 numbers available, since the first number cannot be the same as the second number. And for the last number, there are 20 remaining numbers to choose from. So, there are 22*21*20=9240 possible sequences.

pentagon [3]

Answer:

1) k = (-8)/5

2) x = 5

Step-by-step explanation:

$6 {k}^{2} + 16k = 0$

$= > 2k(3k + 8) = 0$

$= > 3k + 8 = \frac{0}{2k} = 0$

$= > 3k = - 8$

$= > k = \frac{ - 8}{3}$

${x}^{2} - 5x = 0$

$= > x(x - 5) = 0$

$= > x - 5 = \frac{0}{x} = 0$

$= > x = 5$

Which equation justifies why seven to the one third power equals the cube root of seven?

Rudiy27

The equation that justifies why seven to the one third power equals the cube root of seven is seven to the one third power all raised to the third power equals seven to the one third times three power equals seven

<h3>How to solve an equation?</h3>

using indices law,

$\sqrt[n]{x} = x^{1 / n}$

Therefore, let's justify

$7^{1/3} = \sqrt[3]{7}$

Hence, the justification is as follows;

$(7^{1 /3}) ^{3} =(7^{1/3})^{3} = 7$

Therefore, the justification of is that seven to the one third power all raised to the third power equals seven to the one third times three power equals seven
