What part of the circumference is an arc whose measure is 30°?<br> 1/12<br> 1/10<br> 1/8<br> 1/6

GrogVix [38]

Answer:

1/12

Step-by-step explanation:

The whole circumference (i.e complete circle) is an arc which measures 360°

in our case, it is given that our arc measures only 30°

the fraction of our arc of 30° to the complete circle of 360° is

30/360

= 3/36

= 1/12

If f(x) is shifted 4 units to the left and 6 units up, what is the equAation of the resulting graphs

irina1246 [14]

Answer:

f= (x-4, y+6) or f= (x-4),(y+6)

Step-by-step explanation:

* when you move to the left you are subtracting from x because eventually you'll get to the negatives, if you were going to the right you would add

* going up from y, you would be adding since the further up you go the higher positive number you'll get, if you were going down it would be subtracting from y

A graduate class consists of six students. What is the probability that at least 5 of them are born either in April or in Octobe

nlexa [21]

Answer:

0.0671% probability that at least 5 of them are born either in April or in October

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they were born in April or October, or they were not. The probabilty of a student being born in April or October is independent of other students. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
