Organize the following polynomial expressions from least to greatest based on their degree:
Mumz [18]

Answer:

Step-by-step explanation:

We have to organize the given polynomials from the least to greatest based on their degrees.

A). x + 2xyz

Here xyz = x^{1}y^{1}z^{1}

Power of x is = 1

Power of y = 1

and power of z = 1

So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3

B). 9x³y²

Degree of this term = power of x + power of y = 3 + 2 = 5

C). 18x²+ 5ab - 6y

Degree of the polynomial = Highest degree of the variable x = 2

D). 4x^{4}+3x^{2}-x-4

Degree of highest degree term 4x^{4} = 4

So sequence of the polynomials based on their degrees will be

C - A - D - B [From lowest to highest]

How many solutions does the following equation have<br> 3(f - 5) = 6f - 12 + 3f
Crazy boy [7]

Answer: Two answers: f=-3

f=3

Step-by-step explanation:

3(f-5)=6f-12+3f

3f-15=6f-12+3f

-15+12=6f+3f-3f

F=-3

Answer2

3(f-5)=6f-12+3f

3f-15=6f-12+3f

3f-6f+3f=-12+15

F=3

US consumers are increasingly using debit cards as a substitute for cash and checks. From a sample of 100 consumers, the average
scoray [572]

Answer:

A. Margin of error = 128.79

B. The 99% confidence interval for the population mean is (7661.21, 7918.79).

Step-by-step explanation:

We have to calculate a 99% confidence interval for the mean.

The population standard deviation is know and is σ=500.

The sample mean is M=7790.

The sample size is N=100.

As σ is known, the standard error of the mean (σM) is calculated as:

\sigma_M=\dfrac{\sigma}{\sqrt{N}}=\dfrac{500}{\sqrt{100}}=\dfrac{500}{10}=50

The z-value for a 99% confidence interval is z=2.576.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_M=2.576 \cdot 50=128.79

Then, the lower and upper bounds of the confidence interval are:

LL=M-t \cdot s_M = 7790-128.79=7661.21\\\\UL=M+t \cdot s_M = 7790+128.79=7918.79

The 99% confidence interval for the population mean is (7661.21, 7918.79).
