A set of data has 50 observations. How many classes would you recommend?​

Answers

Answer 1

Answer:

6 classes

Step-by-step explanation:

If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.

We have n = 50 and:

2^5 = 32 < 502^6 = 64 > 50

As per above described 2 to k rule, we are taking k = 6.

So 6 classes should be used.

Write a fraction on the blank to make the comparison true .Use the fractions form the box .Explain how you choose your number 3/5>3-4

Answers

Answer:

Explained

Step-by-step explanation:

So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5

3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6

and 3-4 is - 1 (which is negative)

since 3/5 is positive and 3-4 is negative. You would know that this is true.

How much larger is the circumference of circle A than the circumference of circle B?

Give your answer to one decimal place.
diameter of circle A is 13 and B is 8

Answers

Answer:

Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Step-by-step explanation:

Formula for Circumference of a circle = πd

Where, d = diameter of circle

Thus:

Circle A diameter = 13

Circle B diameter = 8

Therefore:

Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)

Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)

✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16

Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Answer:

x=16

Step-by-step explanation:

7x−2(3x−5)=26

Use the distributive property to multiply −2 by 3x−5.

7x−6x+10=26

Combine 7x and −6x to get x.

x+10=26

Subtract 10 from both sides.

x=26−10

Subtract 10 from 26 to get 16.

x=16

Graph if needed:

Answer:

x = 16

Step-by-step explanation:

7x - 2(3x - 5) = 26 ​

7x - 6x + 10 = 26

7x - 6x + 10 - 10 = 26 - 10

x = 26 - 10

x = 16

18 is 14 percent of what?

Answers

Answer:

18 is 14% of 128.5714

Step-by-step explanation:

it's 77.78

Step-by-step explanation:

14: 18*100 =

(14*100): 18 =

1400: 18 = 77.78

Now we have: 14 is what percent of 18 = 77.78

Question: 14 is what percent of 18?

Percentage solution with steps:

Step 1: We make the assumption that 18 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=18$100%=18.

Step 4: In the same vein, $x\%=14$x%=14.

Step 5: This gives us a pair of simple equations:

$100\%=18(1)$100%=18(1).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{18}{14}$100%x%=1814

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{14}{18}$x%100%=1418

$\Rightarrow x=77.78\%$⇒x=77.78%

Therefore, $14$14 is $77.78\%$77.78% of $18$18.

What is the domain of the function?

Answers

Answer: -6 ≤ x < 4

Step-by-step explanation:

Open circles on a graph mean that that point is not included

Filled in circles on a graph mean that that point is included

As a result, the end point (-6, -6) is included while (4, 8) is not

The domain is all possible x-values so the graph can be anywhere from:

-6 ≤ x < 4

Note that there are no possible values for the x-value of 4

The distance between the x values in the center point and a point included in the graph will give you the radius.
The x values are 4 units apart (-5 to -1) so your radius is 4 units

What is the volume of a cylinder, in cubic m, with a height of 6m and a base diameter

Answers

Answer:V= 1526.8m3

Step-by-step explanation: pi (9)2(6)

A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

What is a cylinder?

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,

Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³

Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

(x-0)^2+{y-(-16)}^e=(√15)^2

→x^2+(y+16)^2=15

Answer:

C. x² + (y + 16)² = 15

Step-by-step explanation:

Equation of circle:

(x - h) + (y - k) = r², where (h, k) is the center and r is the radius

We have:

h = 0, k = -16, r = √15

Substitute the given into the equation above and get the equation of the given circle:

(x - 0)² + (y - (16))² = (√15)² ⇒x² + (y + 16)² = 15

Correct choice is C
