Mathematics
1 answer:
krok68 [10]3 years ago
7 0

Answer:

x>48/5 or x<-3/2

Step-by-step explanation:

<u><em>Solve for x</em></u>

<u>a) 12x + 7 < -11</u>

12x < -11-7

12x < -18

x < -18/12

<em>⇒ Simplify: divide the numerator by 6</em>

x < -3/2

<u>b) 5x – 8 > 40</u>

5x > 40+8

5x > 48

x > 48/5

Therefore, x>48/5 or x<-3/2.

Answer:

Relative Frequency Method

Step-by-step explanation:

If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.

Now if I intend to find out approximately how many Heads will

occur in 300 throws, I simply use the result or experimentation data that I have.

This is done below:

Relative Frequency of Obtaining a Head= 13/25 =0.52

Number of Heads obtained in 300 throws

= Relative Frequency X Number of Trials

=0.52 X 300

=156

This is an example of how relative frequency method works.

A table of values of a linear function is shown below.
ikadub [295]

Given:

A table of values of a linear function.

To find:

The slope, y-intercept and equation of the function.

Solution:

Take any two points on the table.

Let the points are (-1, -3) and (0, -6).

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{-6-(-3)}{0-(-1)}

$m=\frac{-6+3}{0+1}

$m=\frac{-3}{1}

m = -3

Slope of the function = -3

y-intercept of the function is the point where x = 0.

In the table y = -6 when x = 0

y-intercept = -6

Equation of a line:

y = mx + c

where m is the slope and c is the y-intercept

y = -3x + (-6)

y = -3x - 6

Equation of a function is y = -3x - 6.
