A spinner has five sections, labeled A, B, C, D, and E. The spinner is spun 84 times, and the results are recorded in the table.What is the experimental probability of the spinner’s landing on A? Round to the nearest percent, if necessary.

Outcome A B C D E
Number of trials 14 20 18 15 17

A.22%

B.20%

C.17%

D.14%.

Answers

Answer 1
Answer: The experimental probability is C. 17%.

17% is derived from the following solution.

14/84 = 0.1666
0.1666 * 100% = 16.66% or 17%

This is based on the result of the experiment conducted.

The theoretical probability of A is 20%. 

1/5 = 0.20
0.20 x 100% = 20%

A is only one event out of 5 letters.

4^3 • 5^3 and 20^3, Are the expressions equivalent? Yes or no?

Answers

Hey there!

4^3 * 5^3 = ?

4^3

= 4 * 4 * 4

= 16 * 4

= [64]

5^3

= 5 * 5 * 5

= 25 * 5

= [125]

125 * 64

= [8,000]

20^3

= 20 * 20 * 20

= 400 * 20

= 8,000

8,000 = [8,000]

Therefore, this statement is TRUE so your answer is: [YES]

Find the product.

3y 2 z(2y 2 z + 4yz - y + z)

Answers

Answer: 48(y*z)^2 - 6z*y^2 - 6y*z^2

Step-by-step explanation: We want to find the product:

3y*2z*(2y*2z + 4yz - y - z)

First, distribute the product:

3y*2z*2y*2z + 3y*2z*4yz -*3y*2z*y - 3y*2z*z

now, let's simplify the equation:

(3*2*2*2)(y*z)^2 + (3*2*4)(y*z)^2 - (3*2)z*y^2 - (3*2)y*z^2

24(y*z)^2 + 24(y*z)^2 - 6z*y^2 - 6y*z^2

48(y*z)^2 - 6z*y^2 - 6y*z^2

If the equation you want to distribute is:

(3y^2z)*(2y^2z + 4yz - y - z)

the distribution is:

(3y^2z)´*(2y^2z) + (3y^2z)*4yz -(3y^2z)*y - (3y^2z)*z

6y^4z + 12y^(2z + 1)*z - 3y^(3z + 1) - (3y^2z)*z

3y^2z*(2y^4yz-y+z)

=6y^(4z)+12y^(1+2z)z-3y^(1+2z)+3zy^(2z)

The area of a rectangular wall of a barn is 55 square feet. It's length is 6 feet longer than the width. Find the length and width of the wall of the barn.

Answers

x - width
x+6 - length

x(x+6)=55\n x^2+6x-55=0\n x^2+11x-5x-55=0\n x(x+11)-5(x+11)=0\n (x-5)(x+11)=0\n x=5 \vee x=-11

x=5 feet
x+6=11 feet

Final answer:

The dimensions of the barn wall are found by setting up and solving a quadratic equation involving its area and the relationship between its length and width. Discarding the nonsensical negative solution, we find that the width of the wall is 5 feet and the length is 11 feet.

Explanation:

Given that the area of the rectangular wall is 55 sq. ft. and the length is 6 ft. longer than the width, we can assign the width as x and the length as x + 6. Therefore, length multiplies width equals to the area of the rectangle, we then have the equation: x * (x + 6) = 55.

After rearranging the equation, we obtain: x² + 6x - 55 = 0. This is a quadratic equation that we can solve using the quadratic formula or by factoring if possible. Factoring results in (x - 5)(x + 11) = 0. Setting each factor equal to zero gives the possible solutions x = 5 and x = -11.

However, since the dimensions of a physical object (in this case, width of the barn wall) cannot be negative, we discard x = -11. Therefore, the barn wall has a width of 5 feet and a length of 5 + 6 = 11 feet.

Renata moved to her new home a few years ago. Back then, the young oak tree in her back yard was 1 9 0 centimeters tall. She measured it once a year and found that it grew at a constant rate. 3 years after she moved into the house, the tree was 2 7 4 centimeters tall.

Answers

It would grow 28 centimeters each year. 274-190=84 which is the difference from 3 years. You would then divide the 84 between three different years to get 28.
