Answer:

The degree of a monomial is the sum of the exponents of the variables.

Therefore,

The degree of the monomial - 20.5 is 0, because there is no variables only numeric terms.

Step-by-step explanation:

To find the degree of monomial.

Basically,

- If one term is present, then it is monomial.

- If two term is present, then it is binomial.

- If three term is present, then it is trinomial.

- If more than three term is present, then it is polynomial.

What’s the square root of -121

irakobra [83]

The answer is 11 i

Explanation:

The square root needs to be a number that can be multiplied by itself and equal the original number.

In this case, the number is 11, 11*11 = 121

However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -

( Depending on your grade/ teacher however, you can put "no solution"

Step-by-step explanation:

Angles in a Right Triangle

When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.

The tangent ratio is defined as:

$\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}$

Opposite leg to angle A is 8 and adjacent leg is 7, thus:

$\displaystyle \tan A=\frac{8}{7}$

Using the inverse tangent funcion:

$\displaystyle A=\arctan\frac{8}{7}$

Calculating:

A = 48.81°

What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% conf

VARVARA [1.3K]

Answer: 271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

$n=00.25(\dfrac{z_{\alpha/2}}{E})^2$

Given : Significance level : $\alpha: 1-0.90=0.1$

By using the standard normal distribution table ,

Critical value : $z_{\alpha/2}=1.645$

Margin of error : $E=0.05$

Then , the required minimum sample size will be :-

$n=0.25(\dfrac{(1.645)}{0.05})^2=270.6025\approx271$

Hence, the required minimum sample size is 271.

How do you model a decimal using a fraction

const2013 [10]

Answer:

If we have to model a decimal using fraction , This is the way you should write

$1.\rightarrow a.b_{1}=\frac{ab_{1}}{10\text{or}(10^1)}\\\\2.\rightarrow a.b_{1}b_{2}=\frac{ab_{1}b_{2}}{100\text{or}(10^2)}\\\\ 3.\rightarrow a.b_{1}b_{2}b_{3}=\frac{ab_{1}b_{2}b_{3}}{1000\text{or}(10^3)}\\\\............\\\\\text{General rule}\\\\n.\rightarrow a.b_{1}b_{2}b_{3}.......b_{n}=\frac{ab_{1}b_{2}b_{3}.....b_{n}}{1000.....0\text{or}(10^n)}$
