Answers

Answer:

31.0

Step-by-step explanation:

The mean of a given set of data is the ratio of the sum of the data to the number of units that make up the data set. It is also called the average of the data set.

Given the data set {22, 34, 37, 23, 45, 21, 29, 37}. There are 8 numbers in the set. The total of these numbers

= 22 + 34 + 37 + 23 + 45 + 21 + 29 + 37

= 248

The mean = 248/8

what value of x is quadrilateral CDEF a parallelogram

Answers

Answer:

x = 2

Step-by-step explanation:

CDEF is a parallelogram.

CE and FD are its diagonals.

Diagonals of a parallelogram bisects each other.

Therefore,

10x - 5 = 4x + 7

10x - 4x = 7 + 5

6x = 12

x = 12/6

x = 2

Thus, for x = 2, CDEF is a parallelogram.

In the quadrilateral CDEF, the value of x is 2.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Quadrilateral CDEF is a parallelogram.

Here, CE and FD are its diagonals.

We know that;

Diagonals of a parallelogram bisects each other.

Therefore, We can formulate;

⇒ 4x + 7 = 10x - 5

Solve for x as;

⇒ 7 + 5 = 10x - 4x

⇒ 12 = 6x

⇒ x = 12/6

⇒ x = 2

Given that ABCD is a parallelogram. Find the following

Answers

Answer:

m=8

m<A=83

m<D=97

Step-by-step explanation:

Angles that are opposite of each other in a parallelogram are equal. Knowing this, we can first conclude that angle A and angle C are equal. We can set up the following equation:

[tex]9m+11=8m+19[/tex]

Subtract both sides by 11

[tex]9m+11-11=8m+19-11\\9m=8m+8[/tex]

Subtract both sides by 8m

[tex]9m-8m=8m+8-8m\\m=8[/tex]

To calculate angle A, plug the value of m into its expression.

[tex]<A=9m+11\\<A=9(8)+11\\<A=72+11\\<A=83[/tex]

In a parallelogram, angles that share a side are supplementary, meaning they add up to 180 degrees. Therefore, angle A and angle D are supplementary. Knowing this, we can set up the following equation:

[tex]180=83+D[/tex]

Subtract both sides by 83

[tex]180-83=83+D-83\\97=D[/tex]

A human heart beats an average of 80 beats per minute. How many beats is this in an hour?

Answers

Answer:

4800 beats an hour

Step-by-step explanation:

there are 60 minutes in and hour

the heart beats 80 times per minute( that is actually a very high heart rate)

80*60=4800 per hour

I believe the answer is an average of 4800 beats per hour.
We know that the heart beats an average of 80 beats per minute and there are 60 minutes in an hour. We can use this information and multiply 80x60 to find the average amount of heartbeats in an an hour.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is y=2x+3.

A) Substitute (x, y)=(-4, 3) in y=2x+3, we get

3=2(-4)+3

3≠-5

B) Substitute (x, y)=(-1, 1) in y=2x+3, we get

1=2(-1)+3

1=1

C) Substitute (x, y)=(0, 0) in y=2x+3, we get

0≠3

D) Substitute (x, y)=(2, 7) in y=2x+3, we get

7=2(2)+3

7=7

E) Substitute (x, y)=(3, 9) in y=2x+3, we get

9=2(3)+3

9=9

F) Substitute (x, y)=(3 12) in y=2x+3, we get

12=2(3)+3

12≠9

G) Substitute (x, y)=(4.5, 12) in y=2x+3, we get

12=2(4.5)+3

12=12
