Answer:

D. [tex]g(x) = x^{2} + 3[/tex]

Step-by-step explanation:

Since the upscaling in the y-axis is not the main focus of this equation (being g(x) and not g(y)), the change is not applied to the x-axis. Hence, we can rule out (x-3)^2 and (x+3)^2 since they apply changes to the x-axis.

Finally, since this is an upscaling of the y-value on the y-axis, the answer is x^2 + 3 and not x^2 - 3.

Step-by-step explanation:

b^(-2) / ab^(-3)

= 1/a * [b^(-2)/b^(-3)]

= 1/a * b = b/a.

P.S. Law of Indices: a^m / a^n = a^(m-n)

Answer:  [tex]\frac{b}{a}[/tex]

Step-by-step explanation:

A variable raised to a negative exponent p is equivalent to 1 divided by the variable raised to a positive exponent p.

In this equation, this rule applies to both b variables as follows:

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

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

After 'solving' for each negative exponent, you can plug them into the previous negative exponents:

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

Afterwards, cancel out b^2 from the top and bottom of the equation to get your final answer, as b^2 / b^2 = 1

[tex]\frac{b}{a}[/tex]

The ratio is 2 : 5 and the smaller portion is 100

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be A = $ 350

Now , the ratio is 2 : 5

So , the total ratio is = 2x + 5x

                                 = 7x

And, the value 7x =  total amount

So , 7x = 350

Divide by 7 on both sides of the equation , we get

x = 50

So , the number 350 in the ratio 2 : 5 is 100 : 250

Hence , the smaller portion is 100

Answer:

The answer is 1/10y

Complete question is;

A manufacturer of cell phone batteries claims that the average number of recharge cycles for its batteries is 400. A consumer group will obtain a random sample of 100 manufacturer's batteries and will calculate the mean number of recharge cycles. Which of the following statements is justified by the central limit theorem?

The Central Limit Theorem tells us that for large sample sizes (in practice n > 30) the sampling distribution of the sample mean will be approximately normal.

A. The distribution of the number of recharge cycles for the sample is approximately normal because the population mean of 400 is greater than 30.

B. The distribution of the number of recharge cycles for the sample is approximately normal because the sample size of 100 is greater than 30.

C. The distribution of the number of recharge cycles for the population is approximately normal because the sample size of 100 is greater than 30.

D. The distribution of the sample means of the number of recharge cycles is approximately normal because the sample size of 100 is greater than 30.

E. The distribution of the sample means of the number of recharge cycles is approximately normal because the population mean of 400 is greater than 30.

Answer:

D. The distribution of the sample means of the number of recharge cycles is approximately normal because the sample size of 100 is greater than 30.

Step-by-step explanation:

We are told that the Central Limit Theorem tells us that for large sample sizes (in practice n > 30) the sampling distribution of the sample mean will be approximately normal. Thus we can pick the correct option as follows:

Option A: This is not the correct answer because it is the sample size (n) that should be greater than 30 and not the population mean as stated.

Option B: This is not the correct answer because the distribution of the sample should correspond to the population shape for large samples because it's only the sampling distribution that is approximately normal.

Option C: This option is not correct because the sample is not meant to have any impact on the population.

Option D: This option is the correct answer because it fulfills the condition of the central limit theorem earlier described.

Option E: This is not the correct answer because just like in option A, it is the sample size (n) that should be greater than 30 and not the population mean as stated.

Answer:

y = -5x - 2/3

Step-by-step explanation:

slope intercept form is "y = mx + b"

y = -5x - 2/3

b = y-intercept

y-intercept means when x = 0

m = slope

slope = -5

Answer:

The value of average temperature during that period=[tex]58^{\circ}[/tex]

Step-by-step explanation:

We are given that

Temperature at time t  is given by

[tex]T(t)=50+6t-\frac{1}{3}t^2[/tex]

We have to find the average temperature during a certain  24-hour period.

We know that

Average value of function

[tex]f_{av}=\frac{1}{b-a}\int_{a}^{b}f(x)dx[/tex]

Using the formula

Average temperature during the period

[tex]=\frac{1}{24-0}\int_{0}^{24}(50+6t-\frac{1}{3}t^2)dt[/tex]

[tex]=\frac{1}{24}[50t+3t^2-\frac{1}{9}t^3]^{24}_{0}[/tex]

[tex]=\frac{1}{24}(50\times 24+3(24)^2-\frac{1}{9}(24)^3)[/tex]

[tex]=58^{\circ}[/tex]

Hence, the value of average temperature during that period=[tex]58^{\circ}[/tex]

The nth term of Arithmetic Sequence

We know the arithmetic sequence with the common difference is defined as

where a₁ is the first term and d is a common difference.

To Determine:

The Rule of the nth term of Arithmetic Sequence

Steps to solve the problem

The 6th term of the Arithmetic sequence be defined as

a₆ = a₁ + (6-1) d

substituting a₆ = 43/12 and a₁ = 11/4 to determine d

43/12 = 11/4 + 5d

switch sides

11/4 + 5d = 43/12

subtract 11/4 from both sides

11/4 + 5d - 11/4 = 43/12 - 11/4

5d  = 5/6

Divide both sides by 5

5d/5 = [5/6] / [5]

d = 1/6

as

a₁ = 11/4

d = 1/6

Therefore, the nth term of the Arithmetic sequence will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting d = 1/6 and a₁ = 11/4

aₙ = 11/4 + (n-1) × 1/6

    = 11/4 + 1/6n - 1/6

    = 31/12 +  1/6n

Therefore, we conclude that the rule will be:

aₙ = 31/12 +  1/6n

[tex] -\frac{x}{4} \le 2 [/tex]

[tex] -x \le 8 [/tex](multiplication property of equality)

Divide both sides by -1. Since we are dividing by a negative number, the sign would change

[tex] x \ge 8 [/tex]

This means that the possible values of x are 8 and any number above 8.

Graphing this, the arrow of directed line would start at 8 and move towards our right hand.
