Answer 1

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Probability of rolling an even number P(A):

[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of flipping tails P(B):

[tex]\frac{1}{2}[/tex]

P(A OR B) = P(A) + P(B) – P(A AND B)

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) =  [tex]\frac{3}{4}[/tex]

Nancy spins the spinner at the right 60 times. Predict how many times the spinner will land on the number 2

the picture is shown of a circle that has 1,4,3,2 those are the numbers

Answers

Since theres 4 numbers and 60 spins if you divide it you get the average number that all the numbers would land on. 2 would be landed on 15 times if it went exactly to the calculations. not 100% sure though

Figure Q has undergone a dilation
Which scale factor was used for the dilation?
A. 1/2


B. 3

C. 1/3


D. 2

Answers

Answer: 2

Step-by-step explanation: the figure has increased by 2 by x and y

What is Dilation?

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

An example of dilation math is a square of side 5 units can be dilated to a square of side 15 units, but the shape of the square remains the same.


Dimensions of Object Q are as follows:

(3 1/3,1)

(3 1/3,2)

(1,1)

(1,2)

Dimensions of Object Q’ are as follows:

(6 2/3,2)

(6 2/3,4)

(2,2)

(2,4)

Dimensions of Object Q to Object Q’ are as follows:

(3 1/3,1) ⇒ (6 2/3,2)

(3 1/3,2) ⇒ (6 2/3,4)

(1,1) ⇒ (2,2)

(1,2) ⇒ (2,4)


Let’s consider each vertex one by one.

The x-coordinate 3 1/3 changed to 6 2/3 and the y-coordinate 1 changed to 2. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 3 1/3 changed to 6 2/3 and the y-coordinate 2 changed to 4. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 1 changed to 2 and the y-coordinate 1 changed to 2. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 1 changed to 2 and the y-coordinate 2 changed to 4. This shows that both the coordinates of Q’ became twice the coordinates of Q.

Therefore, the scale factor in this dilation is 2.

So, the correct option is Option (D) 2

The correct answer is C 59

Explanation

An angles degree will always equal 180

This triangle is a right angle so it has given you 90° and 30.6
