With a coupon, you can get a pair of shoes that normally costs $84 for only $72. What percentage was the discount? Hint: First subtract to find the amount of discount$, then divide it by the original price.​

Answers

Answer:

14[tex]\frac{2}{7}[/tex]%

Step-by-step explanation:

We can just follow the hint.

Amount of discount = $84 - $72

                                 = $12

Percentage of discount = [tex]\frac{12}{84}[/tex] × 100%

                                       = 14[tex]\frac{2}{7}[/tex]%

Answer:

14.3% discount.

Step-by-step explanation:

Heya! So by the hint that they gave us, I subtracted 72 from 84, and then divided the 12 by 84. The true answer is 0.143 (rounded to the hundredth), getting you close to the initial 12. I hope this helped at least a little bit!

A survey asks a random sample of 1500 adults in Ohio if they support an increase in the state sales tax from 5% to 6%, with the additional revenue going to education. Let ^ p denote the proportion in the sample who say they support the increase. Suppose that 13% of all adults in Ohio support the increase. The standard deviation of the sampling distribution is

Answers

Answer:

The standard deviation of the sampling distribution is [tex]\sigma =0.0087[/tex]

Step-by-step explanation:

From the question we are told that

     The sample size is  n =  1500

     The population proportion is  [tex]p = 0.013[/tex]

Generally the standard deviation of this sampling distribution is mathematically represented as

      [tex]\sigma = \sqrt{ \frac{p (1- p)}{ n} }[/tex]

=>     [tex]\sigma = \sqrt{\frac{0.13(1-0.13)}{1500} }[/tex]

=>   [tex]\sigma =0.0087[/tex]

     

The standard deviation of the considered sampling distribution of the proportion supporting the increase is 0.0027 approx.

How to find the sample standard deviation for distribution of a sample proportion?

Suppose the sample proportion be denoted by [tex]\hat{p}[/tex], then, its distribution is normally distributed with mean [tex]p[/tex] and the standard deviation of distribution of [tex]\hat{p}[/tex] is given by

 [tex]\sigma = \sqrt{\dfrac{p(1-p)}{n}}[/tex]

where n is the sample size. It is true until [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

For the given case, we're given that:

Sample size=  n = 10Proportion average value = p = 13% = 0.13 Standard deviation = [tex]\sigma = \sqrt{\dfrac{0.13(1-0.13)}{1500}} = \sqrt{\dfrac{0.13 \times 0.87}{1500}} \approx 0.0027[/tex]

Thus, standard deviation of the sampling distribution is approximately 0.0027

Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 19 years?​

Answers

Answer:

The answer to the nearest CENT is A= 11699.69

The amount of money would be $11.4 in the account after 19 years.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A = P(1+r/100)ⁿ

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given that Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously.

p = $4.700

r =4.8%

t = 19 years

A = P(1+r/100)ⁿ

Substitute the values of p,r, and t in the formula,

A = 4.700 (1 + 4.8/100)¹⁹

A = 4.700 (1 + 0.048)¹⁹

A = 4.700 (1.048)¹⁹

A = 11.454133

Rounded to the nearest cent

A = 11.4

Therefore, the amount of money would be $11.4 in the account after 19 years.

Find m

m = (y2 - y1)/(x2 - x1)

y1 = 0

x2 =0

x1 = -2

m = (4 - 0)/(0 - - 2)

m = 4/2 = 2

Two numbers each have one decimal place. Is it possible for their product to be a whole number? Explain.​

Answers

Answer:  No.

Step-by-step explanation: Unless the tenth place is a 0, a product of a 2 numbers with 1 decimal place cannot have a product for a whole number, even if you went on forever.

When two decimal places add up to one whole, the total of the two decimal places is a whole number. The addition of relocating the decimal point after the multiplication when multiplying decimals is the only difference between multiplying whole numbers and multiplying decimals.

What does the decimal number system mean?The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the term used to describe the method of representing numbers in the decimal system.A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point. 12.5 is a decimal number, for instance.In mathematics, the decimal system—also known as the Hindu-Arabic number system or the Arabic number system—is a positional numeral system that uses 10 as its base and calls for the use of 10 different numbers, including 0, 1, 2, 3, 4, 5, 6, 7, and 8. To indicate decimal fractions, a dot (decimal point) is also necessary.
