there are 6 flavors of candy in a bag strawberry lime lemon cherry or grape what is the probabilty of selecting blueberry
Furkat [3]

Number of strawberry = 1

Number of Lime = 1

Number of Lemon = 1

Number of Cherry = 1

Number of Blueberry = 1

Total number of candies = 1 +1 + 1 +1 +1 +1 =6

favourable outcome = 1

P(of selecting blueberry ) = \frac{Number of Blueberry }{Total number of candies}

P(of selecting blueberry) = \frac{1}{6}

P(of selecting blueberry) = 0.1666

P(of selecting blueberry) = 0.17

What is the equation of the line through the points (3, 2), (8, 5), (13, 8) and (18, 11)?
Alika [10]

Answer:

Option D.) y = 3/5 + 1/5

Step-by-step explanation:

First, we find the Slope using the formula: m = y2 - y1/x2 - x1

You may choose any two points but I will use these two for no reason at all.)

Points: (3,2) and (8,5)

m = y2 - y1/x2 - x1

m = 5 - 2/8 - 3

m = 3/5

Now that we have the slope, we can now find the Slope Intercept Form by using the Slope Form Formula. (need at least one point and slope.)

Formula: y - y1 = m(x - x1)

Point: (3,2) (you may choose any point but I will choose this for no reason at all xD)

y - y1 = m(x - x1)

y - 2 = 3/5(x - 3)

y - 2 = 3/5x - 9/5

y - 2 = 3/5x - 9/5

y = 3/5x - 9/5 + 10/5 (2 can be is any fraction that consists of the numerator multiplied twice by the denominator, such as 2/1, 4/2, 8/4, etc.)

y = 3/5 + 1/5

In 2002, the price of mailing a letter was $0.34 for the first ounce or part of an ounce and $0.21 for each ounce or part of an
tensa zangetsu [6.8K]
The equation would be .34 + .21(x -1) = C  where x is the number of ounces and C = the cost.  Let x = 4 to answer the question.
.34 + .21(4-1) = C   Do the work in the parentheses
.34 + .21(3) = C   multiply
.34 + .63 = C   Add
.97 = C
The cost to mail the letter is $0.97.
