If a single 20 sided dice is tossed once what is the probability of rolling a 15 or 17

For a single 20 sided dice, a chance to get a certain number would be 1/20. For 2 numbers it will be a 2/20 chance, which can be simplified to a 1/10 chance that you will roll a 15 or a 17.

Jack works after school. Each day he is paid a set amount, plus an hourly wage. Look at the table. Choose the linear function f

daser333 [38]

Answer:

A. $f(x) = 10x + 8$

Step-by-step explanation:

The equation in slope-intercept form, $f(x) = mx + b$ , can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.

Using two points (1, 18), and (1.5, 23), find the slope (m):

Slope (m) = $\frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10$

Find b, by substituting x = 1, f(x) = 18, and m = 10 into $f(x) = mx + b$ .

$18 = (10)(1) + b$

$18 = 10 + b$

Subtract 10 from each side

$18 - 10 = b$

$8 = b$

$b = 8$

Substitute m = 10 and b = 8 into $f(x) = mx + b$ .

✅Thus, the linear function that can be used to find Jack's pay would be:

$f(x) = 10x + 8$
