Howdy! My name is Christian and I’ll try and help you with this question!

Date: 9/29/20 Time: 9:08 am CST

Answer:

{ (1, 3), (2, 3), (3, 3), (4, 3) }

Explanation:

This is because for each x value, the number on the left of the set, there is no other x values of the same number, ( 1, 2, 3, 4)

Hope this helps you with your question!

Sincerely,

Christian

A rectangle swimming pool measures 22.3 feet by 75 feet find the perimeter of the swimming pool using the correct number of sign

Liula [17]

Perimeter = add all the sides

Pool has 4 sides
So
22.3 + 22.3 = 44.6
75+75 = 150
150 + 44.6 = 194.6ft

Using the slot method and multiple cases, calculate the probability that you would roll 3 sixes.

kotegsom [21]

Answer:

P = 1/216

the probability that you would roll 3 sixes is 1/216

Step-by-step explanation:

For a given dice, there are six possibilities.

We have;

1,2,3,4,5,6

The probability of rolling a six(6) is;

P(6) = 1/6

Then, the probability of rolling 3 sixes is a multiple of the P(6), given as;

P = P(6) × P(6) × P(6)

P = 1/6 × 1/6 × 1/6

P = 1/216

the probability that you would roll 3 sixes is 1/216

Suppose that water is pouring into a swimming pool in the shape of a right circular cylinder at a constant rate of 8 cubic feet

adell [148]

Answer:

dh/dt = 0,07 ft/min

Step-by-step explanation:

The swimming pool has the shape of right circular cylinder, therefore its volume is

V(c) = π*x²*h

Where x is the radius of the base and h the height

We take differentiation on both sides of the equation to get:

dV/dt = π*x²*dh/dt

The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.

Then:

8 = π*x²*dh/dt

dh/dt = 8 / π*x²

dh/dt = 8/113,04

dh/dt = 0,07 ft/min

Remi invests £600 for 5 years in a savings account.

Daniel [21]

Answer:

225600

Step-by-step explanation:

Simple interest formula:

A = P(1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

So...

A = 600(1 +(75 x 5) )

75 x 5 = 375

1 + 375 = 376

600 x 376 = 225600

A = 225600
