How do I solve a probability question?

1 answer:

3 0

Solving probability is finding the likely hood of an event. So for example if you have 4 red circles and 3 yellow and you were trying to find the probability of picking yellow, you would add all of the blocks together. After you would put the problem into a fraction; with 3(the amount we are given) on top and 7(the total) on the bottom. I hope that helps but if it’s a more specific question, let me know!

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.

Does anyone know if this is correct or how to do this? (part a,b, and c)

stepladder [879]

Part A you would use 200-L ( since you have 400 feet total 200 feet would equal length plus width)

Part B 200 - 80 = 120

Part C 200-90 = 110

area = 90 x 110 = 9900 square feet
