Answer:
b
Step-by-step explanation:
Use the formula y1-y2÷x1-x2
7-6÷(-6)-(-3)
7-6=-1
(-6)-(-3)=3
So, you know that you have a slope of -1/3. so, b would be your answer
Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%
Answer:
D. 
Step-by-step explanation:
Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.
Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.
We have been given that probability of an event is 2/7.
Upon substituting our given values in above formula we will get,




Therefore, the odds of the same event are
and option D is the correct choice.
Answer:
8a+1=33
Step-by-step explanation:
you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33
