Answer:

3/4 hours or 45 minutes

Step-by-step explanation:

3 hours and 45 minutes is equivalent to 3 3/4 hours

We divide 3 3/4 by 5 (the number of weeks) to receive how much Jeremiah practices per week

We convert 3 3/4 to an improper fraction and receive 15/4

We now have 15/4 ÷ 5 =

Convert 5 into a fraction

5/1

15/4 ÷ 5/1 =

Keep, change, flip

We keep our first fraction

15/4 ÷ 5/1 =

Change our sign from division to multiplication

15/4 • 5/1 =

And flip or find the reciprocal of the second fraction

15/4 • 1/5 =

Then we multiply our numerators together and our denominators together

15/4 • 1/5 = 15/20

Then we simplify our fraction by dividing the numerator and denominator by the largest common factor, 5

15/5= 3

20/5= 4

And we receive our answer: 3/4 hours

Jeremiah practiced 3/4 hours or 45 minutes on the 5th week.

A service center receives an average of 0.6 customer complaints per hour. Management's goal is to receive fewer than three compl
True [87]

Answer:

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.

Step-by-step explanation:

We have the mean during a time-period, which means that the Poisson distribution is used to solve this question.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

A service center receives an average of 0.6 customer complaints per hour.

This means that \mu = 0.6h, in which h is the number of hours.

Determine the probability that exactly four complaints will be received during the next eight hours.

8 hours means that h = 8, \mu = 0.6(8) = 4.8.

The probability is P(X = 4).

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 4) = \frac{e^{-4.8}*4.8^{4}}{(4)!} = 0.18203

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.

Please help me thank you
gayaneshka [121]

Answer:

x = 6

Step-by-step explanation:

First, separate the problem into -\frac{2x}{3} +9=\frac{4x}{3} - 3

Then, Subtract 9 from both sides of the equation. -\frac{2x}{3} +9-9=\frac{4}{3} * x - 3-9

Simplify. -\frac{2x}{3}=\frac{4x}{3}-12

Multiply 3 to each side, which will give you -2x = 4x - 36

Subtract 4x from each side  -2x - 4x = 4x - 36x - 4x

Combine like terms: -6x = -36

Divide both sides by -6

Your answer should be 6

Answer:

x=15

Step-by-step explanation:

This is an equilateral triangle.  That means all sides are equal and all angles are equal

An equilateral triangle has angle measurements of 60 degrees

60 =4x

Divide each side by 4

60/4 = 4x/4

15 =x

1. Based on the information in the table, is the cost of the apples proportional to the weight of apples?
lina2011 [118]

Answer:

  1. yes
  2. no

Step-by-step explanation:

When a number of similar calculations are required, a spreadsheet can reduce the tedium.

1. The price is a constant $1.88 per pound, so is proportional to the weight.

_____

2. The price is not proportional to the number of toppings.

__

The cost of the pizza is $8.99 plus $1.50 per topping. The base cost being non-zero ensures that the overall cost is not proportional to the number of toppings.
