Find 3f(x)+2g(x).
What is this answer

Answers

Answer:

12x-20

Step-by-step explanation:

f(x)=6x-8

3f(x)=3(6x-8)

3f(x)=18x-24

g(x)=-3x+2

2g(x)= -6x+4

3f(x)+3g(x)=(18x-24)+(-6x+4)

Answers

Answer: 150 degrees

Step-by-step explanation:

Answer:

149°F

Step-by-step explanation:

The Celsius measure is 65° . We know the relation between Celsius and Farenheight as ,

⇒ C/5 = F-32/89

⇒ 65/5 = F-32/9

⇒ 13 = F-32 / 9

⇒ F - 32 = 13 × 9

⇒ F = 117 + 32

F = 149 °F

Hence the Faeenheight measure is 149°F .

find the measure of arc URT

Answers

Hello!

This question is about relating vertical angles and their arc lengths.

Vertical angles have equal angle measures, meaning that they will also have the same arc measure.

We know that arc QR and arc UT have equal angle measures because they are formed with vertical angles.

That means since we know the measure of the other two arcs, which will both be 125 since they are formed with vertical angles, we can solve for the two unknown arc lengths.

A circle is 360 degrees, meaning that we can make the following equation,

[tex]360=QR+UT+125+125[/tex]

[tex]QR+UT+250=360[/tex]

[tex]QR+UT=110[/tex]

Since QR = UT

[tex]QR/UT=55[/tex]

Now, we can solve for arc URT using all the arc measures we have.

[tex]URT=125+55+125[/tex]

[tex]URT=305[/tex]

Hope this helps!

Write the polynomial in factored form as a product of linear factors:
p(a) = a^3 + 3a^2+ 9a + 27
zeros of polynomial.

Answers

Answer:

Step-by-step explanation:

p(A) = a^3 + 3a^2 + 9a + 27

put brackets around the 1st and second terms and another set around the 3rd and 4th

P(a)= (a^3 + 3a^2) + (9a + 27)

Using the distributive property, pull out the common factor for each of the 2 terms that contain the brackets.

P(a) = a^2 ( a + 3) + 9(a + 3)

Let a + 3 = x

P(a) = a^2x + 9x

Put brackets around these 2 terms

P(a)= x(a^2 + 9)

Substitute a + 3 for x

P(a) = (a + 3) ( a^2 + 9)

Peyton is going to invest $440 and leave it in an account for 5 years. Assuming the
interest is compounded annually, what interest rate, to the nearest tenth of a percent,
would be required in order for Peyton to end up with $520?

Answers

Answer:

The required interest rate would be of 3.4% a year.

Step-by-step explanation:

The amount of money earned in compound interest, after t years, is given by:

[tex]P(t) = P(0)(1+r)^t[/tex]

In which P(0) is the initial investment and r is the interest rate, as a decimal.

Peyton is going to invest $440 and leave it in an account for 5 years.

This means that [tex]P(0) = 440, t = 5[/tex]

So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P(t) = 440(1+r)^5[/tex]

What interest rate, to the nearest tenth of a percent, would be required in order for Peyton to end up with $520?

This is r for which P(t) = 520. So

[tex]P(t) = 440(1+r)^5[/tex]

[tex](1+r)^5 = \frac{520}{440}[/tex]

[tex]\sqrt[5]{(1+r)^5} = \sqrt[5]{\frac{52}{44}}[/tex]

[tex]1 + r = (\frac{52}{44})^{\frac{1}{5}}[/tex]

[tex]1 + r = 1.034[/tex]

Then

[tex]r = 1.034 - 1 = 0.034[/tex]

The required interest rate would be of 3.4% a year.

So we have to find the unit rate, and we do that by getting that 6 down to a 1, and we do that by dividing 6 by 6 and then we gotta do that on the other side too:

6 ÷ 6 = 1

128 ÷ 6 = 21.3 (simplified)

A shoemaker claims his best product has an average lifespan of exactly 14 years. A skeptical customer asks for evidence (data) that might be used to evaluate this claim. The customer was provided data collected from a random sample of 45 people who used the product. Using the data, an average product lifespan of 15 years and a standard deviation of 6 years was calculated. Select the 95%, confidence interval for the true mean lifespan of this product.

Answers

Answer:

The 95%, confidence interval for the true mean lifespan of this product is between 13.2 and 16.8 years.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 45 - 1 = 44

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 44 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.0154

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.0154\frac{6}{\sqrt{45}} = 1.8[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 15 - 1.8 = 13.2 years

The upper end of the interval is the sample mean added to M. So it is 15 + 1.8 = 16.8 years.

The 95%, confidence interval for the true mean lifespan of this product is between 13.2 and 16.8 years.

Solve and check each equation below . show all work . 24=g+14. f-9=12​

Answers

Answer:

g = 10

f = 21

Step-by-step explanation:

Given equations:

24 = g + 14

f - 9 = 12​

24 = g + 14

Subtract 14 from both sides

24 - 14 = g + 14 - 14

10 = g

g = 10

Check:

24 = g + 14

24 = 10 + 14

24 = 24

f - 9 = 12​

Add 9 to both sides

f - 9 + 9 = 12​ + 9

f = 21

Check:

f - 9 = 12​

Many professional sports are arguing that they need a new stadium to be competitive, as newer stadiums can bring in more fan revenue which can in turn allow teams to buy more expensive players. Some major league baseball teams have built new stadiums in the past decade. Consider the attendance (in millions) in the last year of the old stadium and the first year of the new stadium. Using a sample of 5 randomly selected teams, researchers would like to determine if there is any evidence that attendance levels differ between using old vs new stadiums. The data for these five teams are shown below:

Team Attendance (in millions)
Old Stadium New Stadium
Cincinnati Reds 1.9 2.4
New York Yankees 4.3 3.7
Philadelphia Phillies 2.3 3.3
Seattle Mariners 2.7 2.9
Washington Nationals 1.9 2.3

Required:
a. Calculate the test statistic appropriate to the correct statistical method.
b. Suppose all assumptions were satisfied for valid inference, and the researcher found a statistically significant lower average attendance in the new stadium compared to the old stadium. (This does not mean that this data support this conclusion - this is just hypothetical.) Does this mean that the new stadium caused attendance to decrease? Why or why not?

Answers

Answer:

Test statistic = 1.1508

Step-by-step explanation:

Given the data provided

We have to make a table and find d and d²

From the calculations I did in the attachment

n = 5

d² = 1.81

d = 1.5

The t test statistic = 1.5/1.3038 = 1.1505

B. No the new stadium may not have caused the attendance t decrease in this case. Other factors could be responsible for the low attendance.

Step-by-step explanation:

Take the total bars sold 1152 then subtract the berry bars 528 and you'll get 624. Next you'll divide the 624 by 24 because that's how many that's in a full box. Finally you'll get your answer of 26 boxes.
