Answer: B
Explanation:
32 marbles in total.
18 red marbles
4 blue marbles
10 green marbles.
You are asked what part of Osteen's marbles are red?
Probability = number of possible outcomes/total number of out outcomes.
P(Red) = 18/32 = 9/16
Both, 18 and 32 are divisible by 2 which gives 9/16. Since 9/16 cannot be reduced any further, we live it as it is. If you wanted to plug this into a calculator that would give 0.5625 which is 56.25% of Osteen's marbles are red.
P(Blue) = 4/32 = 1/8. 1/8 = 0.125 which 12.5% of his marbles are blue.
P(Green) = 10/32 = 5/16. 5/16= 0.3125 which 31.25 of his marbles are green. When you add 0.5625 + 0.125 + 0.3125 = 1 which is 100%. All probabilities add up to 1.
Hope this elaborate explanation helps.
He has 12 quarters and 15 dimes. 12 x .25=3. 15 x .1 = 1.5
1.5 + 3 = 4.5
Hope this helps
Answer:
22
Step-by-step explanation:
Basically you can think of Devaughn as 3x and Sydney as 1x, which gives you 4x=88. 88/4= 22, so Sydney is 22
Given,
Diameter of circle=15cm
so, radius= D/2= 15/2
we know that circumference=perimeter
2πr= 2×22/7×15/2=47.1428cm
Not 100% sure but they should equal 22 because they are across from each other they would be the same answer so you set it equal to each other and solve for the answer
