Sample space for tossing 2 coins = (H, H), (H, T), (T, T), (T, H)
P(Exactly one head) = (H, T) (T, H) = 2 events
P( E) = 2/4 = 1/2
In short, Your Answer would be 1/2
Hope this helps!
Answer:
The scatter plot for the provided data is attached below.
Step-by-step explanation:
A scatter plot is a graphical representation of the relationship between two variables. It displays how one variable affects the other variable.
The data for the average pain level, on the scale of 1 to 10, and the amount of dosages of pain medication provided to the volunteers is as follows:
Average pain level Dosage (mg)
6.0 0
5.8 50
5.2 100
4.9 150
3.9 200
3.6 250
3.5 300
The scatter plot for the provided data is attached below.
Answer:
From the image, we can see that ∠AOC = ∠AOB + ∠BOC
We are given the following values:
∠AOC = 104
∠AOB = 7x + 30
∠BOC = 9x + 42
Plugging these values in the equation above:
∠AOC = ∠AOB + ∠BOC
<em>104 = 7x + 30 + 9x + 42</em>
<em>104 = 16x + 72</em>
<em>16x = 32</em>
x = 2
Now that we have the value of x, we can easily find the value of ∠BOC
We are given that:
∠BOC = 9x + 42
∠BOC = 9(2) + 42 (since x = 2)
∠BOC = 18 + 42
∠BOC = 60°
Therefore, ∠BOC is 60 degrees
