Answer:

Impossible

Step-by-step explanation:

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.

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

Answer:

26 boxes of raisin bars

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.

1152-528=624 ➗ 24 = 26

Answer:

Arthimatic is the answer

Answer:

Step-by-step explanation:

Here,

[Taking 'A' = 'a']

[tex]a \: = \: 4\pi {r}^{2} [/tex]

Then for 'r',

[tex] = > 4\pi {r}^{2} = a[/tex]

[tex] = > {r}^{2} = \frac{a}{4\pi} [/tex]

[tex] = > r = \sqrt{\frac{a}{4\pi} }[/tex]

[tex] = > r = \frac{1}{2}\sqrt{ \frac{a}{\pi} } [/tex]

Hence,

Option C is correct .

Answer:

[tex]\frac{-7}{-5}[/tex]

-7/-5

is the slope.

or -1 -2/-2  

you pick.

Step-by-step explanation:

Δy/Δx

-7-0 / 0-5

-7 / -5

-7/-5

is the slope.

change in y over change in x

y2-y1 over x2-x1

simplify if possible.

-1 -2/-2

it's negative.

Answer:

Slope = 1 2/5 or 1.4

Step-by-step explanation:

Using the y2 - y1/x2 - x1 format, you first replace the variables with the points (5 and 0 can be x1, y1, while 0 and -7 can be x2, y2)

-7 - 0/0 - 5

Now subtract: -7 - 0 = -7; 0 - 5 = -5

You would get -7/-5, which simplified: 1.4 or 1 2/5

Answer:

  B) ΔCAT is congruent to ΔDOG

Step-by-step explanation:

If angles are congruent, the triangles are similar. When both corresponding angles and corresponding sides are congruent, the triangles are congruent.

  ΔCAT is congruent to ΔDOG

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]

Answer:

21.3:1

Step-by-step explanation:

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)

So 128 to 6 days in simplest terms is 21.3 hours to 1 day

hope this helps:)

Answer:

vanilla,cone

Step-by-step explanation:

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.

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.

Answer:

Quinn

For Quinn:

275 points - - > 5 min

5000 points - - > x min

--------------------------------------

275*x=5*5000-->x=90.9 minutes

For Delilah:

675 points - - > 15 min

5000 points - - > y min

--------------------------------------

675*x=15*5000-->y=111.1 minutes

90.9<111.1, so Quinn will score 5000 points faster
