In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie

son4ous [18]

Answer:

Step-by-step explanation:

1) find the total candies

7 + 8 + 5 + 9 = 29

2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find

- red = 7/29

- blue = 8/29

- yellow = 5/29

- green = 9/29

3) compound probability

(red + blue)/29 = 15/29

(yellow + green)/29 = 14/29

(blue + yellow + green)/29 = 22/29

Use the distance formula to find The distance between the points (-1 ,3) and (2,6) write you answear as a square root, do not gi

olga nikolaevna [1]

Answer:

d = $3\sqrt{2}$

Step-by-step explanation:

The distance formula is d = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2} -y_{1} )^{2} }$

Plug in the points.

d = $\sqrt{(2-(-1))^{2}+(6 -3 )^{2} }$

Solve

d = $\sqrt{18}$

Simplify by separating 18 into 9x2

d = $\sqrt{9(2)}$

Take the square root of 9 to finish simplifying

d = $3\sqrt{2}$
