Part a)
There are 4 outcomes on spinning the first wheel and 2 outcomes on spinning the second wheel. So the tree diagram will have 4 nodes at the start and each of these 4 nodes will be further divided into 2 nodes. First 4 nodes show the possible outcomes on spinning of first wheel and next nodes show for every possible outcome on spinning of first wheel there can be 2 possible outcomes of the second wheel. The tree diagram is attached below:

Part b)
Total possible outcomes of first wheel = 4
Favorable outcome is getting a 2. So number of Favorable outcome = 1
Thus, probability of getting a 2 = 1/4 = 0.25

Total possible outcomes of second wheel = 2
Probability of getting an A = 1/2 = 0.5

The probability of getting either a 2 or an A = Sum of the both individual probabilities

So,
If you spin both wheels the probability that you get either a 2 or an A = 0.75

Answer:

60=2(20)+2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2(20)+2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).

Plz help!!!! Geometry
never [62]

The little lines inside the two angles mean they are the same.

The 3 inside angles of a triangle equal 180 degrees.

One angle is 146 , so the other two need to equal 180-146 = 34 total.

34/ 2 = 17

Both angle 1 and angle 2 are 17 degrees each.

Complete the equation for the linear function whose graph contains the points (-1,-2) and (3.10)
tatuchka [14]
That's point-slope form:

y - y1 = m(x - x1)

Where y1 is the y-value of a point on the line, x1 is the x-value, and 'm' is the slope.

So let's find out what goes in the first blank.

As we can see, they replaced 'x1' with -1, and one of our points have an x-value of -1, that point is (-1, -2), this means y2 must be -2:

y + 2 = m(x + 1)

Now let's find the slope between the two points.

m = y2-y1/x2-x1

m = (10+2)/(3+1)

m = 12/4

m = 3

So the slope is 3, plug that in:

y + 2 = 3(x + 1)

Answer:

\huge\boxed{\sf  18 cm\²}

Step-by-step explanation:

The figure consists of 2 rectangles.

<u>Rectangle 1 Area:</u>

Length = 5 cm

Width = 2 cm

Area = Length * Width

A = 5 * 2

A = 10 cm²

<u>Rectangle 2 Area:</u>

Length = 4 cm

Width = 2 cm

Area = 2 * 4

A = 8 cm²

<u>Area of the whole figure:</u>

= Rectangle 1 + Rectangle 2

= 10 + 8

= 18 cm²

\rule[225]{225}{2}

Hope this helped!
