Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.
Answer:
See below in bold.
Step-by-step explanation:
There are 2 even and 6 odd numbers in the list.
A.
Prob(Picking an odd number) = number of odd numbers / total of numbers
= 6/8 = 0.75.
Prob(Picking a 10) = 1/8 = 0.125.
Answer = 0.75 * 0.125 = 0.09375
= 0.094 to 3 dec. places.
B.
Prob( Picking and even) = 2/8 = 1/4.
Prob( Picking another even without replacement) = 1/7.
Answer = 1/4 * 1/7 = 1/28
= 0.036 to 3 dec. places.
C.
There are 5 numbers greater than 4.
Prob(Picking a number > 4) = 5/8.
Prob( Picking a 1 without replacement) = 1/7.
Answer = 5/8 * 1/7
= 5/56
= 0.089 to 3 dec. places.
