There’s 180° in any triangle, so you can solve by doing 180-102-55= 78-55= 23° as our final answer.
Answer:
Step-by-step explanation:
or, 3(2y-4) = 1(y+7)
or, 6y-12 = y +7
or, 6y-y = 7+12
or, 5y = 19
or, y = 19/5

Step-by-step explanation:
Given that a researcher is looking for 10 people to participate to a medical study on diabetes.
Suppose the researcher has to find his 10 participants, out of 25, then he has to get 9 participants in 24 trials, and the last one in 25th trial
Out of 24 trials, 9 participants selecting is binomial with p =0.1 because there are only two outcomes and each trial is independent of the other.
Hence Prob for selecting 9 from 24 = Prob for 9 successes in 24 trials
=P(X=9)
= ...i
the probability that the researcher will have to call 25 candidates in order to find his 10 participants
= i * prob for 25th trial success

Looking up the height of Mt. Whitney, you can see it's 14,505 feet tall. Rounding that number to the nearest multiple of 1000 requires you to look at the hundreds digit which is 5. And the rule for rounding is "5 or greater, round up, 4 or smaller, round down". Since it's 5, we round up, giving 15000 feet</span>
