Solve (x-5)^2=3 apex!!!

Anna71 [15]

Answer:

x = 5 + √3 and x = 5 - √3

Step-by-step explanation:

First take the square root of both sides...

x - 5 = ±√3

Now add 5 to both sides....

x = 5 ± √3

so x = 5 + √3 and x = 5 - √3

What is a margin of error, and how is it used to establish a confidence interval? What is the confidence interval used for?

Pie

Answer:

A Margin of error : Generally margin can be defined as a statistical concept that informs the researcher or any person carrying statistical active the percentage by which his /her result will differ from the real population value.

B Margin of error is used to establish a confidence interval by adding and subtracting the statistical value (i.e sample proportion or sample mean ) from the margin of error

C Generally the confidence interval tell the researcher the probability by which a population parameter(sample proportion or sample mean) will fall between two set of values(Upper limit and the lower limit )

In a candy store a $5.00 jar of candy is on a boat 50% of what is the discount? What is the sale price of the jar of candy?

Effectus [21]

STEP 1:
Discount $= Price times discount %

=$5.00 * 50%
=$5.00 * 0.50
=$2.50 discount amount

STEP 2:
Sale price= Original $ - Discount amount

=$5.00 - $2.50
=$2.50 sale price

ANSWER: Discount amount is $2.50 and the sale price is also $2.50.

Hope this helps! :)

The product of two integers is eighty,their quotient is five.Write both integers in numerical order and separated by a comma,no

Goryan [66]

SOLUTION

Let the two integers be x and y.

Now, the product of x and y, is 80, that is

$\begin{gathered} x\times y=80 \\ xy=80\ldots\ldots\text{.equation 1} \end{gathered}$

The quotient of x and y is 5, that is

$\begin{gathered} x\div y=5 \\ \frac{x}{y}=5\ldots\ldots\ldots\ldots\text{.}\mathrm{}\text{equation 2} \end{gathered}$

From equation 2, make x, the subject, we have

$\begin{gathered} \frac{x}{y}=5 \\ \text{cross multiplying } \\ 5\times y=x \\ x=5y \end{gathered}$

Now substitute the x for 5y into equation 1, we have

$\begin{gathered} xy=80 \\ 5y\times y=80 \\ 5y^2=80 \\ \text{dividing by 5} \\ y^2=\frac{80}{5} \\ y^2=16 \\ \text{take square root of both sides } \\ \sqrt[]{y^2}=\sqrt[]{16} \\ \text{square cancels root} \\ y=4 \end{gathered}$

Now substitute y for 4 into any of the equations.

Let us use equation 1 again, we have

$\begin{gathered} xy=80 \\ x\times4=80 \\ 4x=80 \\ x=\frac{80}{4} \\ x=20 \end{gathered}$

Hence the answer is 4, 20
