sveta [45]

Answer:

see explanation

Step-by-step explanation:

Solve the inequality

y - 2 < - 5 ( add 2 to both sides )

y < - 3

The number line going from - 8 to + 2

Since y is not equal to - 3 then an open circle at y = - 3

Since y is less than - 3 the shaded to the left of y = - 3

Make a table of ordered pairs for the equation. y= 1/2x − 3
Dennis_Churaev [7]

Answer:


Step-by-step explanation:

Please enclose the fractional coefficient inside parentheses:  y= (1/2x) − 3 for greater clarity.

Make a table of ordered pairs:

x    y = (1/2)x - 3

0                   -3

1            (1/2)(1) - 3 = -2 1/2

3           (1/2)(3) - 3 = -3/2

The y-intercept is the point at which x = 0, and (from the table) is -3.  Plot a dark dot at (0, -3).

Now graph (3, -3/2), leaving a dark dot.

Draw a line thrugh (0, -3) and (3, -3/2).

A mini-lottery involves selecting 2 numbers between 1 and 10. What is the probability of correctly picking the two numbers?
Igoryamba

The probability of correctly picking the two numbers is 2/10.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of correctly picking the two numbers = (numbers that have to be selected to win / total numbers)

2/10
