Answer:

(E) 29.0

Step-by-step explanation:

If a tag is drawn at random from each box, the expected value of the sum of the tags is the sum of the expected values for each tag.

The expected value for each tag is the mean value of the numbers in its box.

EV = \frac{1+2+3+4+5+6+7+8+9+10}{10} +\frac{20+21+22+23+24+25+26+27}{8} \\EV = 5.5 +23.5\\EV= 29

The expected value of the sum of the numbers on the two selected tags is 29.

Answer:

25deg 55deg 100deg

Step-by-step explanation:

There are 180deg in a triangle. We know one angle is 30deg more and the other 75deg more than the smallest angle so we subtract that from 180.

180-75-30 = 75

We divide 75deg by 3 because there are 3 angles.

75/3 = 25

So we know the smallest angle is 25deg. We have to add 30deg to one angle and 75 to the other in oder to find the remaining angles.

25+30 = 55deg

25+75 = 100deg

So the angles are 25deg, 55deg, and 100deg.
