Shtirlitz [24]

There are 143 men. There are 65 education majors. There are 26 men who have an education major. So, the total number of students who meet the criteria (man or education major) = Total number of Men + Total number of Education Majors - Total number of men with education majors = 143 + 65 - 26 = 182.

There are a total of 291 students. So, the probability that the student was a man or education major = 182 / 291 = 0.625.

One-third of a number yields twelve. Which equation could be used to find the number?

Answer:

1/3n=12

Step-by-step explanation:

The reason why it is 1/3n=12, is because you know that the number in front of n is 1/3. By figuring that out, you have already ruled out 3n=12 and 3n=-12. Finally, you know that 12 is a positive number leaving you with 1/3n=12.

(a) The integral is equal to the area of the triangle; it has height 20 and base 10, so the area is 20*10/2 = 100.

(b) The integral is equal to the area of the semicircle with radius 10. It's also under the horizontal axis, so the area is negative. The semicircle has area $\frac{\pi10^2}2=50\pi$ , so the integral is -50π.
