If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number
Answer:
first quartile is 14
Step-by-step explanation:
{13,15,19,25,35}
first quartile = (13+15)/2 = 14
second quartile = 19
third quartile = (25+35)/2 = 30
16.79+28.49=45.28
50-45.28=4.72

By the Pythagorean theorem, the missing side is -sqrt7. The definition of sin is side opposite over hypotenuse, so go into Q2 and make an angle and label the side opposite the angle with a 3 and the hypotenuse a 4. The other leg is -sqrt7 cuz x is negative in Q2. The cosine of an angle is the side adjacent over the hypotenuse, so the cos then is -sqrt7/4
