Part A:
For this one, you have to find the median. So first you would put them in order from least to greatest. After you do that you should get,
TEAM L: 4, 4.8, 9, 9.4, 9.75, 13, 17
TEAM M: 3.2, 6, 6.25, 8, 9.5, 9.7, 14
TEAM N: 1, 4.75, 5.6, 13, 14.5, 19, 20
next go from side to side crossing them out evenly till you get to the number in the center.
TEAM L: 9.4
TEAM M: 8
TEAM N: 13
the question asks which team scores more consistently so that would be the team with the highest marking which is team n
so your answer for part A is TEAM N would be awarded the team with the most consistent scoring
part B: you find the average by finding the mean. To find the mean you must add all the numbers up and then divide by how many numbers there are. First we are going to add them up,
TEAM L: 4+17+13+9.4+9+9.7+4.8 = 66.95
TEAM M: 6+14+8+9.7+9.5+6.25+3.2 = 56.65
TEAM N: 1+20+19+13+14.5+4.75+5.6 = 77.85
lastly since all of them consist of 7 numbers, you will divide all the solutions by 7 giving you,
TEAM L: 9.56 (rounded)
TEAM M: 8.09 (rounded)
TEAM N: 11.12 (rounded)
the question asks which team has the higher average score, therefore TEAM N would be the answer since it consist of the highest number.
so your answer for part B is TEAM N would be awarded the team with the highest average score.
ANSWERS....................
PART A: TEAM N would be awarded the team with the most consistent scoring.
PART B: TEAM N would be awarded the team with the highest average score.
Answer:
35/128 ≈ 0.2374
Step-by-step explanation:
The number of combinations of 7 things taken 3 at a time is ...
7·6·5/(3·2·1) = 7·5 = 35
The number of sequences in which the coins can land is 2^7 = 128.
Of those 128 sequences, 35 will have exactly 3 heads.
The probability is 35/128.
Answer:
The answer that is <em>not </em>true when x = -4 is <u>B</u>.
Step-by-step explanation:
Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.
A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.
Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.
Finally D. -4/4 divided equals -1, so that would make it -1 = -1.
B is the only one that doesn't make sense, therefore you have your answer.
