f(x) = x2. What is g(x)?

Answer:

The perimeter of the larger folder is 40 in

Step-by-step explanation:

This is because it says the two folders are similar this means that the width of the larger folder is 8 inches because the scale factor is 4/3. You can see this when you divide the length of the larger folder by the length of the smaller folder. So, if you solve 8+12+8+12 to find the perimeter you will get 40 inches

Answer: 120 Packages

Step-by-step explanation:

Given

75 random packages are check

3 package is found faulty

So, the percentage of error is

[tex]\Rightarrow \dfrac{3}{75}\times 100=4\%[/tex]

i.e. 4% packages is faulty

For 3000 sample, expected faulty packages are

[tex]\Rightarrow 3000\times \dfrac{4}{100}=120\ \text{Packages}[/tex]

Answer:

1) Parellel because if she had sliced perpendicular, she would have gotten a square and a triangle.

2) Perpendicular because if she had sliced parallel, she would have gotten a (once more) square and a triangle.

1) First shape and Last shape (the cylinder and the cone).

2) First shape and Second shape (the pyramid and the cone).

1) This would be a cone - I included a picture of it.

2) This would be a triangular pyramid - I included a picture of it.

Answer: Program C allows students to earn a Mathematics degree (B.A. or B.S.) by combining courses in the Department of Mathematics with courses from one other department.  In most areas of specializations, mathematical and/or quantitative courses in other departments are part of the math degree program.  All Program C students take a minimum of five core math courses:  Calculus I, Calculus II, Calculus III, Introduction to Linear Algebra, and a proofs course, usually either Introduction to Abstract Algebra or Fundamental Properties of Spaces and Functions I.

16/25

Step-by-step explanation:

Given:

Leon had 84 paper clips.

He gave [tex]\dfrac{3}{4}[/tex] of them to Joe.

Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.

To find:

How many paper clips did Justin get?

Solution:

Leon had 84 paper clips and he gave [tex]\dfrac{3}{4}[/tex] of them to Joe.

Number of paper clips Joe has = [tex]\dfrac{3}{4}\times 84[/tex]

                                                    = [tex]63[/tex]

Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.

Number of paper clips Justin has = [tex]\dfrac{2}{7}\times 63[/tex]

                                                       = [tex]18[/tex]

Therefore, Justin has 18 paper clips.

Answer:

8350.92 = Surface area

Step-by-step explanation:

Use formulas

Length times width for the base

Base times height / 2 for the Triangles

Add them all up and you've got your answer

Answer:

a. The number of people that should be in the pilot study are 600 people

b. The point estimate is 0.62[tex]\overline 6[/tex]

c. At 95% confidence level the true population proportion of potential car buyers of hybrid vehicle is between the confidence interval (0.588, 0.6654)

d. Two ways to reduce the margin of error are;

1) Reduce the confidence interval

2) Use a larger sample size

Step-by-step explanation:

a. The given parameters for the estimation of sample size is given as follows;

The margin of error for the confidence interval, E = 4% = 0.04

The confidence level = 95%

The sample size formula for a proportion as obtained from an online source is given as follows;

[tex]n = \dfrac{Z^2 \times P \times (1 - P)}{E^2}[/tex]

Where, P is the estimated proportions of the desired statistic, therefore, we have for a new study, P = 0.5;

Z = The level of confidence at 95% = 1.96

n + The sample size

Therefore, we have;

[tex]n = \dfrac{1.96^2 \times 0.5 \times (1 - 0.5)}{0.04^2} = 600.25[/tex]

Therefore, the number of people that should be in the pilot study in order to meet this goal at 95% confidence level is n = 600 people

b. The point estimate for the population proportion is the sample proportion  given as follows;

[tex]\hat p = \dfrac{x}{n}[/tex]

Where;

x = The number of the statistic in the sample

n = The sample size

From the question, we have;

The number of potential car buyers, n = 600

The number of respondent in the sample that indicated that they would consider purchasing a hybrid, x = 376

Therefore, the point estimate, for the proportion of potential car buyers that would consider buying a hybrid vehicle, [tex]\hat p[/tex] = 376/600 = 0.62[tex]\overline 6[/tex]

c. The confidence interval for a proportion is given as follows

[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

Therefore, we get;

[tex]CI=0.62 \overline 6\pm 1.96\times \sqrt{\dfrac{\hat{0.62 \overline 6}\cdot (1-\hat{0.62 \overline 6})}{600}}[/tex]

C.I. ≈ 0.6267 ± 0.0387

The 95% confidence interval for the true population proportion of potential buyers of hybrid vehicle, C.I. =  (0.588, 0.6654)

d. The margin of error is given by the following formula;

[tex]MOE_\gamma = z_\gamma \times \sqrt{\dfrac{\sigma ^2}{n} }[/tex]

Where;

[tex]MOE_\gamma[/tex] = Margin of error at a given level of confidence

[tex]z_\gamma[/tex] = z-score

σ = The standard deviation

n = The sample size

Therefore, the margin error can be reduced by the following two ways;

1) Reducing the confidence interval and therefore, the z-score

2) Increasing the sample size

Answer:

x= 3

Step-by-step explanation:

Given data

Ratio= 5:2:x

Combined ratio= 5+2+x

                        = 7+x

Total amount of money= $15000

Let us apply the part to all method

Hence for Matthew whose share = $7500

5/7+x=  7500/15000

Cross multiply we have

7500*(7+x)= 15000*5

52500+7500x= 75000

Collect like terms we have

7500x= 75000-52500

7500x=22500

x= 22500/7500

x=3

Hence the value of x= 3

Answer:

48 units

b= 48 units

Step-by-step explanation:

pythag is [tex]a^2+b^2=c^2[/tex]

we have a and c

so substitute them in

[tex]14^2+b^2=50^2[/tex]

now you can solve

[tex]196+b^2=2500[/tex]

subtract 196 from both sides

[tex]b^2=2500-196[/tex]

subtract

2500 - 196 = 2304

[tex]b^2=2304[/tex]

solve for the square root

square root of 2304= 48

therefore b= 48 units

$32.3

Step-by-step explanation:

First write 30% in the decimal form

30/100 = 0.3

than the equation written in the form

x = 19 + (19 - 0.3× 19)

x = 19 + ( 19 - 5.7)

x = 19 + 13.3

x =$ 32.3
