Answer:
<u>The correct answer is B. 36</u>
Step-by-step explanation:
1. Let's review the information given for answering the question correctly:
Data set given:
18
36
11
45
36
19
14
18
36
2. What is the mode for this data set?
Let's recall that the Statistical Mode is the number that is more frequently repeated in a group of numbers. If no number is repeated, then there is no mode for the list or set.
In this specific set, we can notice that 18 is repeated two times and 36 is repeated three times. Therefore, the mode for this set of ages of people riding a bus is 36.
<u>The correct answer is B. 36</u>
Dory = 11 x Carly
Together => d + c = 156
11c + c = 156
12c = 156
C = 156 : 12
C = 13
Carly biked 13 miles
Dory = 11 x c = 11 x 13 = 143 miles
Prove
143 + 13 = 156 miles together
Step-by-step explanation:
C
15 - 7 = 8
the difference of 2 odd numbers, and the result is an even number disproving the original statement.
3, x, x+6 are the first 3 terms of G.P
common ratio is x/3=x+6/x
so we cross multiply x×x=3×x+6
ײ= 3x+18 so we have x²-3x-18
(x-6)(x+3)=0
the possible value of x are 6 and -3
b) tenth term of the seauence
first of all the possible sequence are 3, 6, 12 and 3, -3, 3
but we need only the positive GP
so the common ratio of.the GP r is 6/3=2
the 10th term of a GP sequence is ar^10-1=ar^9
where a = first time
3×2^9=3×512=1536
the 10th term is 1536
