Answer:
Probability ball: white - P(W)P(W);
Probability ball: even - P(E)P(E);
Probability ball: white and even - P(W&E).
Probability ball picked being white or even: P(WorE)=P(W)+P(E)-P(W&E).
(1) The probability that the ball will both be white and have an even number painted on it is 0 --> P(W&E)=0 (no white ball with even number) --> P(WorE)=P(W)+P(E)−0P(WorE)=P(W)+P(E)−0. Not sufficient
(2) The probability that the ball will be white minus the probability that the ball will have an even number painted on it is 0.2 --> P(W)−P(E)=0.2P(W)−P(E)=0.2, multiple values are possible for P(W)P(W) and P(E)P(E) (0.6 and 0.4 OR 0.4 and 0.2). Can not determine P(WorE)P(WorE).
(1)+(2) P(W&E)=0 and P(W)−P(E)=0.2P(W)−P(E)=0.2 --> P(WorE)=2P(E)+0.2P(WorE)=2P(E)+0.2 --> multiple answers are possible, for instance: if P(E)=0.4P(E)=0.4 (10 even balls) then P(WorE)=1P(WorE)=1 BUT if P(E)=0.2P(E)=0.2 (5 even balls) then P(WorE)=0.6P(WorE)=0.6. Not sufficient.
Answer: E.
find the mean, median, and mode of the data set. round to the nearest tenth. 7,7,14,15,4,1,7,2,15,9,5
Arisa [49]
Here is the mean, median, and mode:
Mean: 1+2+4+5+7+7+7+9+14+15+15 = 86/11 ≈ 7.82
Median: 7
Mode: 7
To find the mean add up all the numbers and divide by the number of numbers
To find the median you just keep on crossing of numbers left to right until you get the middle number
To find the mode just look at which number is most commonly seen

Step-by-step explanation:
student
whole number between 4 and 8 is 5,6 and7
and between 12 and 16 is 13,14 and 15
That would mean every word in the english language includes every letter of the alphabet.
A word with a 1/2 chance of a vowel is “Boat”
632.16 inches per hour is the answer. Find the conversion rate of feet to inches, which is just 1 foot = 12 inches. Then, multiply 52.68 by 12 to get the answer.
Hope this helped.
