Workout the probability that spinner A lands on 2 and spinner b does not land on b

Answers

Spinner diagram isn't attached. A related spinner diagram has been attached below to provide an hypothetical solution to the problem

Answer:

4 / 15

Step-by-step explanation:

For the numbered spinner :

P(landing on 2) = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3) = 3

Required outcome = (1) = 1

P(landing on 2) = 1 /3

Lettered spinner :

P(does not land on b)

Total possible outcomes = (A, B, C, D, E)

Required outcome = (a, c, d, e)

P(does not land on b) = 4 / 5

Hence,

P(lands on 2, does not land on b) in this scenario is :

1/3 * 4/5 = 4 / 15

Solve : t+2t squared

Answers

Answer:

t=0 or t=-1/2

Step-by-step explanation:

Solve for t over the real numbers:

t (2 t + 1) = 0

Split into two equations:

t = 0 or 2 t + 1 = 0

Subtract 1 from both sides:

t = 0 or 2 t = -1

Divide both sides by 2:

A cooler contains 12 bottles of apple juice and 18 bottles of orange juice. You reach into the cooler without looking and pull out one bottle of apple juice. Then you reach into cooler and pull out another bottle of juice. What is the probability of pulling apple juice and then pulling another apple juice?

Answers

Answer:

P = 0.232

Step-by-step explanation:

In the cooler, we have 12 bottles of apple juice and 18 bottles of orange juice.

This adds up to a total of 30 bottles.

Now we want to find the probability of pulling a bottle of apple juice after you pulled one bottle of apple juice.

The probability of pulling a bottle of apple juice at the beginning is equal to the quotient between the number of apple juice bottles in the cooler and the total number of bottles in the cooler,

This means that 12 out of 30 are apple juice, then the probability of getting first a bottle of apple juice is:

p = 12/30

Now, we want to find the probability of getting another, we will do the same calculation than above, but now the number of bottles of apple juice is 11 (because we took one) and the total number of bottles is 29.

In this case, the probability is:

q = 11/29

The joint probability (the probability of both events happening) is equal to the product of the individual probabilities.

Then the probability of pulling apple juice and then pulling another apple juice is:

P = p*q = (12/30)*(11/29) = 0.232

A triangle has sides with lengths of 21 meters, 70 meters, and 73 meters. Is it a right triangle?

Answers

Step-by-step explanation:

It is close, but not exactly a right triangle.

If it were a right triangle, we would have ...

This Inflatable Crayon has a diameter of 8 in a length of 40 inches and is topped with a cone shaped tip with a height of 12 inches Round your answer to the nearest tenth of an inch.

Answers

Answer:

Assuming you want to know the volume,

volume = 2210.6 in³

Step-by-step explanation:

radius = diameter/2 = 8/2 = 4 in

area of base = πr² = (3.14)(4²) = 50.24 in²

volume of tube portion = base area x height = 50.24 x 40 = 2009.6 in³

cone volume = 1/3bh = 1/3(50.24)(12) = 200.96 in³

total volume = 2009.6 + 200.96 = 2210.56 in³

The area of a square is 1800 in2, how long is each diagonal?

Answers

9514 1404 393

Answer:

  60 in

Step-by-step explanation:

The area of a square can be computed as ...

  A = (1/2)d^2 . . . . where d is the length of the diagonal

For an area of 1800 in^2, the diagonal length can be found as ...

  1800 in^2 = 1/2d^2

  3600 in^2 = d^2

  d = √3600 in = 60 in

The length of each diagonal is 60 inches.

solve the system using substitution x=-4y y=2x+9

Answers

Answer: x=-4

Step-by-step explanation:

Given

x=-4y

y=2x+9

Rephrase equation to find y value in terms of x

y=-x/4

y=2x+9

Use substitution (substitute value of y)

2x+9=-x/4

Multiply -4 on both sides

-4(2x+9)=-4(-x/4)

-8x-36=x

Add 8x on both sides

-8x-36+8x=x+8x

-36=9x

Divide 9 on both sides

-36/9=9x/9

x=-4
