Answer:

The fist one doesnt make sense as a term but other two are monomials

Step-by-step explanation:

Answer:

y = -4x-15

Step-by-step explanation:

y = ax+b

-19=a+b

-7=-2a+b

==> a = -4

b = -15

Answer:

18a^3b^2/2ab

To simplify the given expression, we apply property of exponents

18/2 = 9

x^m / x^n= x^ (m-n) In division we subtract the exponents

So given expression becomes

9a^2b

The answer has only positive exponents

i think this is what you want?

The simplified exponential notation of the given expression is [tex]9a^2b[/tex].

The given expression is: [tex]\frac{18a^3b^2}{2ab}[/tex]

An expression in the form of [tex]a^pb^qc^r[/tex].. is called exponential expression.

We can write the above expression as:

[tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex]

We know that [tex]\frac{a^m}{a^n} =a^{m-n}[/tex]

[tex]\frac{a^{3} }{a} =a^{3-1} =a^{2} \\\frac{b^{2} }{b}=b^{2-1} =b[/tex]

So, [tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex] =[tex]9a^2b[/tex]

Hence, the simplified exponential notation of the given expression is [tex]9a^2b[/tex].

Answer:

There is only 1 solution

[tex](x,y) = (1,4)[/tex]

Step-by-step explanation:

Given

Lines A and B

Required

The number of solution for a pair of A and B

From the graph, lines A and B have only one point of intersection.

This point of intersection represents the solution

Since, there is only 1 point, there is only one solution.

Answer:

  D  There is an infinite number of solutions to the system of equations

Step-by-step explanation:

When you put the first equation in standard form by dividing it by 2, you get ...

  x -2y = 4

When you put the second equation in standard form by dividing it by 8, you get ...

  x -2y = 4

These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.

There is an infinite number of solutions.

Answer:

3x

Step-by-step explanation:

Step-by-step explanation:

f(x) = -2x^2-4x+11

y = -2(x+1)²+13

Use the vertex form, y=a(x−h)²+k, to determine the values of a, h, and k.

a= -2

h= 1

k= 13

Final answer is, f(x) = -2(x - 1)² + 13

Answer:

f(x) = - 2(x + 1)² + 13

Step-by-step explanation:

f(x) = - 2x² - 4x + 11

f(x) = a(x - h)² + k

a = - 2, b = - 4, c = 11

h = - [tex]\frac{b}{2a}[/tex]

h = - [tex]\frac{-4}{2(-2)}[/tex] = - 1

k = - 2( - 1)² - 4( - 1) + 11 = 13

f(x) = - 2(x + 1)² + 13

Answer:

5

Step-by-step explanation:

Answer:

(a) The mean is 0.04

The standard deviation is approximately 0.0196

(b) The sampling distribution of p is not approximately normal because n·p is less than 10

(c) Given that n  = 400, we have;

i) The mean is 0.04

The standard deviation is approximately 0.0098

ii) The sampling distribution is always centered at the population mean, regardless of the sample size

iii) When the sample size increases, the standard deviation decreases

(d) The sampling distribution of p is approximately normal because n·p and n·(1 - p) are both at least 10

Step-by-step explanation:

(a) From the question, we have that the actual proportion of all adult Americans who watch online = 0.04

Given that the sample size, 'n' is 100 which is larger than 30, we can assume that the distribution of the sample mean is normal

Therefore, the mean (proportion) of the sample, P = The mean (proportion) of the population = 0.04

The mean, P = 0.04

The standard deviation, σ = √((p·(1 - p))/n)

∴ σ = √((0.04·(1 - 0.04))/100) ≈ 0.0196

(b) The sampling of p is approximately normal, given that the sample size, 'n' = 100 which is randomly selected from the population, we have;

The sampling distribution = n·p  = 100 × 0.04 = 4 <10

Therefore, the sample is not approximately normal because the sampling distribution, n·p = 4 which is less than 10

c) Given that n  = 400, we have;

p = 0.04 = The [population mean

The standard deviation, σ √((0.04·(1 - 0.04))/400) ≈ 0.0098

According to the central limit theorem when the sample size increases, the mean approaches the population mean, therefore, the sampling distribution is always centered at the population mean, regardless of the sample size

When the sample size increases, the standard deviation decreases

(d) Given that when the sample size, n = 400, we have;

n·p = 400 × 0.04 = 16 > 10

Similarly, we have;

n·(1 - p) = 400 × (1 - 0.04) = 384 > 10

The sample is approximately normal

Therefore, the sampling distribution of p is approximately normal because np and n(1 - p) are both at least 10

Answer: the answer is the 3rd bubble:)

Step-by-step explanation:

The following conclusion is reached concerning the results represented by the dot plots:

The mean absolute deviation is a test of variability of a data set which is the average distance between each of the data point in the data set and the mean.

Find the mean absolute deviation for each dot plots.

Mean Absolute Deviation for Brand A:

The points are, 1,1,2,2,2,3,4,4,5,5,5,5,6,6,7,7,8,8,8,9

Mean = (1 + 1 + 2 + 2 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 6 + 7 + 7 + 8 + 8 + 8 + 9)/20 = 98/20

Mean = 4.9

Mean Absolute Deviation = [(1 - 4.9) + (1 - 4.9) + (2 - 4.9) + (2 - 4.9) + (2 - 4.9) + (3 - 4.9) + (4 - 4.9) + (4 - 4.9) + (5 - 4.9) + (5 - 4.9) + (5 - 4.9) + (5 - 4.9) + (6 - 4.9) + (6 - 4.9) + (7 - 4.9) + (7 - 4.9) + (8 - 4.9) + (8 - 4.9) + (8 - 4.9) + (9 - 4.9)] / 20

= [(3.9) + (3.9) + (2.9) + (2.9) + (2.9) + (1.9) + (0.9) + (0.9) + (0.1) + (0.1) + (0.1) + (0.1) + (1.1) + (1.1) + (2.1) + (2.1) + (3.1) + (3.1) + (3.1) + (4.1)] / 20

= 40.4/20

Mean Absolute Deviation for brand A = 2.02

Mean Absolute Deviation for Brand B:

The points are, 1,3,3,4,4,4,4,4,5,5,5,6,6,6,6,8,8,9,10,10

Mean = (1 + 3 + 3 + 4 + 4 + 4 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 6 + 8 + 8 + 9 + 10 + 10)/20

Mean = 111/20 = 5.55

Mean Absolute Deviation = [(1 - 5.55) + (3 - 5.55) + (3 - 5.55) + (4 - 5.55) + (4 - 5.55) + (4 - 5.55) + (4 - 5.55) + (4 - 5.55) + (5 - 5.55) + (5 - 5.55) + (5 - 5.55) + (6 - 5.55) + (6 - 5.55) + (6 - 5.55) + (6 - 5.55) + (8 - 5.55) + (8 - 5.55) + (9 - 5.55) + (10 - 5.55) + (10 - 5.55)] / 20

Mean Absolute Deviation = 38.1/20

Mean Absolute Deviation for brand B = 1.905

Therefore, the following conclusion is reached concerning the results represented by the dot plots:
