Answer:

Probability, P(getting 2 toppings)= 0.1984

Step-by-step explanation:

Probability, P(1 toppings)= 1/7

Probability P of getting a particular topping is q = 1 - P = 1 - 1/7 = 6/7

Probability of( getting 2 toppings)= 7!/(2!5!)(1/7)^2 × (6/7)^5

P(getting 2 toopings)= (5040/240) × (0.020)× (0.4627)

P(getting 2 toppings)= 21 × 0.00948 = 0.1984

What is the angle of B. Round your answer to the nearest hundredth​
Mila [183]

Answer:

B = 53.13

Step-by-step explanation:

Since this is a right triangle, we can use the tan function

tan B = opposite side/ adjacent side

tan B = 4/3

Take the inverse tan of each side

tan ^-1 (tan B) = tan^-1 (4/3)

B = 53.13010235

To the nearest hundredth

B = 53.13

V = 249,000(0.929)^t

Step-by-step explanation:

100% - 7.1% = 92.9% = 0.929

0.929 must be raised to t, the number of years.

V = 249,000(0.929)^t

Do a and b have the same value in the equations 2(a-1.1)=5.8 and 5/2b-2 3/4=7 1/4
luda_lava [24]

Answer:

  • Yes

Step-by-step explanation:

Solve each equation and compare the solutions

1.

  • 2(a - 1.1) = 5.8
  • a - 1.1 = 5.8/2
  • a - 1.1 = 2.9
  • a = 2.9 + 1.1
  • a = 4

2.

  • (5/2)b - 2 3/4 = 7 1/4
  • 2.5b = 7 1/4 + 2 3/4
  • 2.5b = 10
  • b = 10/2.5
  • b = 4

Both a and b have same value

yKpoI14uk [10]

Answer:

10 pizzas

Step-by-step explanation:

Jaxson is throwing a pizza party. He has 1\tfrac{1}{4}1 4 1 ​ pounds of cheese available and he needs \tfrac{1}{8} 8 1 ​ pound of cheese to make each pizza. How many pizzas can he make?

We can interprete the above question as:

1/8 pounds of cheese = 1 pizza

1 1/4 pounds of cheese = x pizzas

Cross Multiply

1/8 × x = 1 1/4 × 1

x = 1 1/4 ÷ 1/8

x = 5/4 ÷ 1/8

x = 5/4 × 8/1

x = 10 pizzas

x = 10 pizzas
