Paco uses a spinner to select a number from 1 through 5, each with equal probability. Manu uses a different spinner to select a

number from 1 through 10, each with equal probability. What is the probability that the product of Manu's number and Paco's number is less than 30?

There are 5 x 10 = 50 different outcomes.

Of them only  3x10, 4x10, 4x9, 4x8, 5x10, 5x9, 5x8, 5x7 and 5x6 are greater or equal than 30. Those are 9 possibilities.

Then 50 - 9 =  41 are the possibilities that the product of the two numbers is less than 30.

The probalility, then, is 41/50 = 0.82

Answer: \dfrac{41}{50}

Step-by-step explanation:

Given : The number of sections in Paco's spinner =5

The number of  sections in Manu's spinner =10

Now, if both spin together , the total number of possible outcomes :-

5\times10=50

The outcomes when the product is more than 30 :-

(5,6), (5,7), (5,8), (5,9), (5, 10), (4,8), (4,9), (4, 10), (3,10)

The number of favorable outcomes for the product of Manu's number and Paco's number is less than 30 :-

50-9=41

Now, the probability that the product of Manu's number and Paco's number is less than 30 :-

=\dfrac{41}{50}

Hence, the probability that the product of Manu's number and Paco's number is less than 30 =\dfrac{41}{50}.

Write an equation in slope-intercept form of the line that passes through (-5, 19) and (5.13).
ruslelena [56]

Answer:

y=-3/5x+16

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(13-19)/(5-(-5))

m=-6/(5+5)

m=-6/10

simplify

m=-3/5

y-y1=m(x-x1)

y-19=-3/5(x-(-5))

y-19=-3/5(x+5)

y=-3/5x-15/5+19

y=-3/5x-3+19

y=-3/5x+16

It would most likely be 41 because when you would round 41 after you would × 41 times 10 equals 410 then you would round it to 400
