Answer:

m = -8

Step-by-step explanation:

Use the slope formula: $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{5+3}{-2+1} =\frac{8}{-1} =-8$

m = -8

The number of girl child per family was recorded for 1000 families with 3 children. The data obtained was as follows: [2] Number

ira [324]

Answer:

$a.\ Probability = 0.426$

$b.\ Probability = 0.574$

Step-by-step explanation:

Given

$Total\ Families = 1000$

Number of Girls : 0 ----> 1 -----> 2 ------->3

Number of Families: 112 -> 314 --> 382 ---> 192

Solving (a): At most one girl

From the table, the number of families with at most one girl is: 112 + 314

i.e.

Number of Girls : 0 ----> 1

Number of Families: 112 -> 314

So, we have:

$At\ Most\ One\ Girl = 112 + 314$

$At\ Most\ One\ Girl = 426$

The probability is then calculated as:

$Probability = \frac{At\ Most\ One\ Girl}{Total}$

$Probability = \frac{426}{1000}$

$Probability = 0.426$

Solving (b): More girls

From the table, the number of families with more girl is: 382 + 192

i.e.

Number of Girls : -----> 2 ------->3

Number of Families: --> 382 ---> 192

So, we have:

$More\ Girls = 382 + 192$

$More\ Girls = 574$

The probability is then calculated as:

$Probability = \frac{More\ Girls}{Total}$

$Probability = \frac{574}{1000}$

$Probability = 0.574$

Select the correct answer

solong [7]

Answer: OPTION C.

Step-by-step explanation:

Given the functions:

$f(x)=2x^2-x-6\\\\g(x)=x^2-4$

We need to divide f(x) by g(x) in order to find $f(x)$ ÷ $g(x)$ . Then:

$f(x)$ ÷ $g(x)$ $=\frac{2x^2-x-6}{x^2-4}$

Factorizing and simplifying, we get:

$f(x)$ ÷ $g(x)$ $=\frac{(2x+3)(x-2)}{(x+2)(x-2)}$

$f(x)$ ÷ $g(x)$ $=\frac{2x+3}{x+2}$
