Answer: C. 180 times
Step-by-step explanation:
From the 60 trials, the percentage of times Laura picked a green marble was:
= 100% - Percentage of times blue and red were picked
= 100% - 25% - 15%
= 60%
If these results were repeated with 300 trials, the number of times Laura would be expected to pick green would be:
= 60% * 300
= 180 times
The triangles are similar because two angles have the same measurements
Yes it is less than 4,862
Answer: 11/12 cups sugar
1 1/4 lbs candy
Step-by-step explanation:
2/3 + 1/4=8/3 + 3/4=11/12
6 1/4 / 5=25/4 x 1/5=25/20=1 5/20= 1 1/4
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
