Answer:
64°
Step-by-step explanation:
∠RQP = 46°
∠PRQ = 180° - 110° = 70°
∠PRQ + ∠RQP + <u>∠RPQ</u> = 180°
70° + 46 + <u>∠RPQ</u> = 180°
116° + <u>∠RPQ</u> = 180°
Find <u>∠RPQ</u>
<u>∠RPQ</u> = 180° - 116° = 64°

Answer:
one number: 8 second number: 4
Step-by-step explanation:
- So, first number is x
- then second number is (x-4):
x+(x+4)=12
2x+4=12
x=4
The mean speed of the 100 cars is 55.4
<h3>How to determine the mean?</h3>
The table of values is given as:
Speed (MPH) Cars
30-39 5
40-49 18
50-59 50
60-69 17
70-79 10
Rewrite the frequency table to include the class midpoints
x f
34.5 5
44.5 18
54.5 50
64.5 17
74.5 10
The mean speed is then calculated as:

So, we have:

Evaluate

Hence, the mean speed is 55.4

I have the scatterplot in front of me, and what the question is asking is what is the probability of the dot chosen being in any of the three categories. They only leave out three dots, so the probability is 17/20 or 85%.
