Answer:

Step-by-step explanation:

The client starts with 105.83 dollars

He requests 40 of which to be subtracted in denominations of 10, meaning 4 10 dollar bills are being removed.

After this he has 65.83 more dollars to withdraw, the next biggest bill denomination is a 50, so lets subtract 50 from our account.

Now he is left with 15.83, subtract another 10 dollar bill.

That leaves us with 5.83, subtract one 5 dollar bill.

Leaving us with 0.83, subtract 3 quarters

That leaves us with 8 cents, lets subtract one nickel, leaving us with 3 cents.

Now with those 3 cents we can subtract 3 pennies.

Meaning the least amount of denominations required is:

1 50-Dollar bill

5 10-Dollar bills

1 5-Dollar bill

3 Quarters

1 Nickel

3 Pennies

Answer:

first I would combine terms which would give me

-4x-7=-7-4x

then I would get the variable on each side of the equal sign

0=0

lastly I would verify the solution

infinite solutions

Step-by-step explanation:

combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions

2. When a large truckload of mangoes arrives at a packing plant, a random sample of 150 is selected and examined for
kirza4 [7]

a) The 90% confidence interval of the percentage of all mangoes on the truck that fail to meet the standards is: (7.55%, 12.45%).

b) The margin of error is: 2.45%.

c) The 90% confidence is the level of confidence that the true population percentage is in the interval.

d) The needed sample size is: 271.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions has the bounds given by the rule presented as follows:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

The variables are listed as follows:

  • \pi is the sample proportion, which is also the estimate of the parameter.
  • z is the critical value.
  • n is the sample size.

The confidence level is of 90%, hence the critical value z is the value of Z that has a p-value of \frac{1+0.90}{2} = 0.95, so the critical value is z = 1.645.

The sample size and the estimate are given as follows:

n = 150, \pi = \frac{15}{150} = 0.1

The margin of error is of:

M = z\sqrt{\frac{0.1(0.9)}{150}} = 0.0245 = 2.45\%

The interval is given by the estimate plus/minus the margin of error, hence:

  • The lower bound is: 10 - 2.45 = 7.55%.
  • The upper bound is: 10 + 2.45 = 12.45%.

For a margin of error of 3% = 0.03, the needed sample size is obtained as follows:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.03 = 1.645\sqrt{\frac{0.1(0.9)}{n}}

0.03\sqrt{n} = 1.645\sqrt{0.1(0.9)}

\sqrt{n} = \frac{1.645\sqrt{0.1(0.9)}}{0.03}

(\sqrt{n}})^2 = \left(\frac{1.645\sqrt{0.1(0.9)}}{0.03}\right)^2

n = 271 (rounded up).

The Bakers want to sell their house for $145,500. After 2 months, the Bakers decided to mark down the price of their house 8% to
kari74 [83]

Answer:

<em>The Bakers are now selling their house for $133,860</em>

Step-by-step explanation:

<u>Percentage</u>

The original price for The Bakers' house was $145,500.

Later they decided to mark down the price of the house by 8%.

Since the new price will be 8% less than the original price, we can calculate the markdown as follows:

8 * $145,000 / 100 = $11,640

The new price is calculated as the original price minus the markdown:

New price = $145,500 - $11,640 = $133,860

The Bakers are now selling their house for $133,860
