What is the probability of landing on an odd number and then landing on a number greater than 7?

Answer:

7.5

Step-by-step explanation:

how i figured it is 18-3 is 15

2*7 is 14 so in turn 7.5 *2 is 15 so

z=7.5

This can be represented in the form of an equation as: 2(x + 3) = 18.So, the correct Answer is A. 2(x+3)=18.

The correct translation of the given sentence is:" twice the sum of a number and three is eighteen".

The equation "2(x + 3) = 18" correctly represents the statement "twice the sum of a number and three is eighteen."

Answer:

407 mm²

Step-by-step explanation:

The formula for the surface area of a clyinder is: A = 2[tex]\pi[/tex]r · (r + h)

Plugging in the given values, we have: A = 2[tex]\pi[/tex]4 · (4 + 12.2)

A = 2[tex]\pi[/tex]4 · (4 + 12.2)

A = 2[tex]\pi[/tex]4 · 16.2

A = 2(3.14)4 · 16.2

A = 406.944

A = 407 (rounded)

Answer: 9.

Step-by-step explanation: To find the MAD (mean absolute deviation) we need to do the following steps below:

1. Find the mean.

2. Subtract the mean from the numbers of the data.

3. Add the results and divide to find the MAD.

The steps are done below:

1. Find the mean: In order to find the mean of a data set, you need to add all the numbers and then divide the result by how many numbers there are in the data set.  In this problem, there are 10 numbers in the data set, so whatever we get for adding the data numbers together needs to be divided by 10.

2. Subtract the mean from the numbers of the data: To do this, we need to subtract 33 from all the numbers on the data.  The following is done below. (*Note: You may notice that most equations like 26 - 33 would be in the negatives, but for data, it has to be positive.  If you ever run into a situation like that, you simply just make it positive).

3. Add the results and divide to find the MAD: Now that we have the results, we add those numbers and then divide to find the MAD.  Make sure that when you divide that it is 10 that you're dividing because once again, there are 10 numbers for the results.

Therefore, 9 is the MAD.

A mean is an arithmetic average of a set of observations. The value of the unknown number is 16.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Let the unknown number be represented by x.

As per the formula of averages, we can write,

Mean = (Sum of observations)/Number of observations

(7 + 8 + 21 + 33 + x)/5 = 17

(69 + x) / 5 = 17

Multiply both the sides of the equation by 5,

(69 + x)/5 × 5 = 17 × 5

69 + x = 85

Subtract 69 from both the sides of the equation,

69 + x - 69 = 85 - 69

x = 16

Hence, the value of the unknown number is 16.

Circumference is diameter x pi so the diameter of the circle is 11.

Radius is half the diameter so the radius is 11/2 = 5.5

area of a circle is r^2 x pi

Area = 5.5^2 x pi

5.5^2 = 30.25

Area = 30.25pi

Answer:

z1 - 2z = 2

Step-by-step explanation:

make 2i stand alone in both equations

therefore, in equation one, we have;

z1-5=-2i

5-z1=2i

we do same in equation 2

z2-3=2i

therefore, comparing the two equations, we can equate them!

2z-3=z1-5

-3+5=z1-2z

2 = z1 - 2z

therefore, z1 - 2z = 2

After the first play, you would move to the left on the line 5 spots (to simulate 5 yards lost) and then make a dot to show your new position. You would do the same thing for the next two plays, moving 5 spots to the left each play and creating a new starting point each time. The total spots moved after the 3 plays is 15 spots to the left.

Answer:

144 deaths

Step-by-step explanation:

So, assuming it's not a leap year 30,300 must be divided by the number of days in the year to get the daily amount.

30,300/365 = 114.339....

since 3 is not greater than 5, the 144 does not round up but stays the same.

(Since you cannot have a fraction of a death)

The length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.

It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

The area of the table runner = 80 square inches

Let's assume the length of the rectangle is L and the width is W

Then L = 5×W ...(1)

L×W = 80 ...(2)

Put the value of L in the equation (2)

5W(W) = 80

5W² = 80

W² = 16

W = ±4

Width cannot be negative.

W = 4 inches putting this value in the equation (1)

L = 5(4) = 20 inches

Thus, the length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.

Answer:

she worked 12 hours as a carpenter and 18 hours as a blacksmith

Step-by-step explanation:

Let x = the number of hours for which she worked as a carpenter

Let y = be the number of hours for which she worked as a blacksmith

Total numbers of hours she worked = 30

x + y = 30 (1)

she earned a total $690. She earned $20 dollar per hour as a carpenter and $25 per hour as a blacksmith.

20 x + 25 y = 690 (2)

Equation (2) - 20 × Equation (1),

We get,

5 y = 90 ⇒ y = 18

After substituting this value in equation (1),

We get, x = 12,

Hence, She worked as a carpenter = x hours = 12 hours

And, as a blacksmith = y hours = 18 hours
