Answer:

Step-by-step explanation:

Yes!

The condition needed to get a proportional answer is the y intercept must be 0. No other value can be added on. It doesn't matter that the constant of proportionality is not an integer. x and y will always differ by 10.2 as a multiplied value

Put another way, the fraction y/x will always give 10.2

The following data points represent the number of children in each household on Maple Street. \qquad 0, 1, 2, 1, 20,1,2,1,20, co

zaharov [31]

Answer:

The mean number of the children is 1.2

Step-by-step explanation:

Given

Children: 0, 1, 2, 1, 2

Required

Determine the Mean number

The mean of a set is calculated as follows;

$Mean = \frac{\sum x}{n}$

Where x is the given set and n is the number of sets

In this case, n = 5 children

Hence;

$Mean = \frac{0 + 1 + 2 + 1 + 2}{5}$

$Mean = \frac{6}{5}$

$Mean = 1.2$

<em>Hence, the mean number of the children is 1.2</em>

Answer:

Step-by-step explanation:

Calculate Greatest Common Factor for :

16, 24 and 36

Factorize of the above numbers :

16 = $2^{4}$

24 = $2^{3}$ • 3

36 = $2^{2}$ • $3^{2}$

Build a prime factors table

Number of times each prime factor

appears in the factorization of :

Prime Factor Number 16 Number 24 Number 36 G.C.F (min)

2 4 3 2 2

3 0 1 2 0

GCF = 2²

Greatest Common Factor is :

If k is a positive integer and n = k(k + 7), is n divisible by 6 ? (1) k is odd. (2) When k is divided by 3, the remainder is 2.

olganol [36]

Answer:

1.) Yes

2.) Yes

Step-by-step explanation:

Given that

n = k(k + 7)

If k is a positive integer and n = k(k + 7), is n divisible by 6 ?

(1) k is odd. Yes.

Let assume that k = 3

Then, n = 3(3 + 7)

n = 3 × 10

n = 30.

30 is divisible by 6.

(2) When k is divided by 3, the remainder is 2. That is,

Let k = 5

Then,

5/3 = 1 remainder 2

Substitute k into the equation

n = k(k + 7)

n = 5(5 + 7)

n = 5 × 12

n = 60

And 60 is divisible by 6.

Therefore, the answer to both questions is Yes.
