Answers

Answer 1

Answer:

132

Step-by-step explanation:

First divide the number of lampreys by the ratio.

162/27=6

Then multiply the result (6) by the oarfish part of the ratio

22*6=132

jay has an album that holds 600 coins. Each page of the album holds 6 coins. If ​39% of the album is​ empty, how many pages are filled with coins ​?

____ pages are filled with coins
Pls help me with this

Answers

9514 1404 393

Answer:

  61

Step-by-step explanation:

If there are 6 coins on each page, then the number of pages for 600 coins is ...

  (600 coins)/(6 coins/page) = 100 pages

__

If 39% are empty, then 100% -39% = 61% are filled.

The number of filled pages is ...

  61% × 100 = 61/100 × 100 = 61 . . . . pages filled

_____

Comment about percent

You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100

("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)

A chemist made six independent measurements of the sublimation point of carbon dioxide (the temperature at which it changes to dry ice). She obtained a sample mean of 196.64 K with a standard deviation of 0.66 K.
1. Use the Student’s t distribution to find a 95% confidence interval for the sublimation point of carbon dioxide.
2. Use the Student's t distribution to find a 98% confidence interval for the sublimation point of carbon dioxide.
3. If the six measurements had been 196.35, 196.32, 196.4 198.02, 196.36, 196.39, would the confidence intervals above be valid? Explain.

Answers

Answer:

(195.733, 197.547)

Step-by-step explanation:

Given that:

Mean, m = 196.64 K

Standard deviation, s = 0.66 K

Sample size, n = 6

Confidence interval :

Mean ± margin of error

Margin of error =Tcritical * s/sqrt(n)

Tcritical at α = 98% ; df = 6 - 1 = 5

Tcritical = 3.3648

Margin of Error = 3.3648 * 0.66/sqrt(6) = 0.9066

Confidence interval = 196.64 ± 0.9066

Lower boundary = 196.64 - 0.9066 = 195.733

Upper boundary = 196.64 + 0.9066 = 197.547

(195.733, 197.547)

Given the measurement :

X = 196.35, 196.32, 196.4 198.02, 196.36, 196.39

Mean = ΣX / n = 1179.84 / 6 = 196.64

Yes, confidence interval will be valid as theean obtained is within the calculated interval

In a class of 30 students 16 have a cat and 15 have a dog there are 11 students who have a cat and a dog what is the probability that a student has a dog given they do not have a cat?

Answers

so we know 11 have cats and dogs and 15 have dogs so do 15-11=4 and divide that by all the students which is 30 and get 13.3%

The probability that a student has a dog given they do not have a cat is 0.1333.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Total number of students = 30

[tex]n(s)=30[/tex]

Number of students have cat = 16

Number of students have dog = 15

Number of students have a cat and a dog = 11

The event is the probability that a student has a dog given they do not have a cat,

[tex]n(e)=15-11[/tex]

⇒ [tex]4[/tex]

Thus the probability that a student has a dog given they do not have a cat is

⇒ [tex]P(e)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(e)=\frac{4}{30}[/tex]

⇒ [tex]P(e)=0.1333[/tex]

Hence we can conclude that the probability that a student has a dog given they do not have a cat is 0.1333.

Answer:

b = 2.8253A = 45.2°C = 107.4°

Step-by-step explanation:

The given sides form the given angle, so the Law of Cosines can be used to find the third side.

  b = √(a² +c² -2ac·cos(B)) ≈ √7.982544072 ≈ 2.8253

The measure of angle A can be found from the Law of Sines.

  A = arcsin(a/b·sin(B)) ≈ arcsin(0.71017) ≈ 45.2°

Angle C can be calculated from the other two angles.

  C = 180° -27.4° -45.2° = 107.4°

The width of a rectangle is 5 centimeters less than the length . The area of the rectangle is 36 centimeters.find the length?

Answers

Answer:

9 centimeters

Step-by-step explanation:

Let the width be represented by l - 5, where l is the length.

Use the area formula, A = lw, and plug in l - 5 as w, and 36 as the area. Then, simplify and factor

A = lw

36 = l(l - 5)

36 = l² - 5l

0 = l² - 5l - 36

Factor:

(l - 9)(l + 4)

Set equal to zero and solve for both solutions:

(l - 9)(l + 4) = 0

l - 9 = 0

l = 9

l + 4 = 0

l = -4

The length cannot be negative, so the answer has to be 9.

The length is 9 centimeters

A rectangular prism has a length of 12 feet, a width of 6 feet, and a height of 2 feet.

What is the volume of the prism?

Enter your answer.

Answers

The volume of the prism is 144 ft^3. If we use the letter V to represent volume, the formula for the volume of a rectangular prism is V=length*width*height. When you plug in the numbers, the equation is V=12*6*2. When you multiply these three numbers together, you get 144. Because you are finding the volume, your units are cubed, so your answer is 144 ft^3. I have attached an image of this problem written out (I’m sorry if the image is bad, I drew it on my phone).
