Since we do not know the exact number of Marbles of each color we will use the data of the experiment to calculate the probability. The probability calculated based on the results of an experiment is termed as experimental probability.
So, we have the calculate the experimental probability that a randomly drawn marble is blue.
Total number of trials = 1200
Number of times blue showed up = 845
Therefore, the experimental probability of randomly drawing a blue marble = 845/1200 = 169/240 = 0.704 (Rounding to nearest thousandth)
Therefore, the probability that a random blue marble is drawn is 0.704 or 169/240
Answer: it should be 67.5
Step-by-step explanation:
8% of $50 is 4 that gets you $54, and 25 percent of 54 is 13.5 that would be the 25% tip add the two together to get $67.5
Answer:
8 dollars per extra person
Step-by-step explanation:
subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8
Answer:
The answer to this question is -11
You are given that DE is congruent to GH (both have two hash marks). Since these are opposite angles EFD and HFG these angles are congruent (corresponding angles opposite congruent sides of a triangle are congruent). It is also true that these angle are vertical angles so you could prove they are congruent that way as well.
DF is congruent to FG (they both have 1 hash mark) so the angles opposite them are congruent (DEF and HGF).
Now you have two angles in one triangle congruent to two angles in the pother. Since the angles in any triangle sum to 180, if two are congruent then the third must be as well so we know that angle D and angle G are congruent.
This is all we need to prove the triangles are congruent by SAS congruent to SAS. Specifically S (DE and GH), A (D and G) and S(DF and GF).
