Answer:
the mean is 73.4
Step-by-step explanation:
you add all the numbers which equals to 367
then divide by 5
Answer:
B
Step-by-step explanation:
the mean of A
= (84 + 84 + 85 + 86) ÷ 4
= 339 ÷ 4
= 84.75
the median of A
= (84 + 85) ÷2
= 169 ÷ 2
= 84.5
84.75 > 84.5
the mean of B
= (74 + 79 + 82 + 87) ÷ 4
= 332 ÷ 4
= 80.5
the median of B
= (79 + 82) ÷2
= 161 ÷ 2
= 80.5
80.5 = 80.5
the mean = the median
the mean of C
= (63 + 66 + 67 + 68) ÷ 4
= 264 ÷ 4
= 66
the median of C
= (66 + 67) ÷2
= 133 ÷ 2
= 66.5
66 < 66.5
the mean of D
= (14 + 16 + 18 + 19) ÷ 4
= 67 ÷ 4
= 16.75
the median of D
= (16 + 18) ÷2
= 34 ÷ 2
= 17
16.75 > 17
Answer:
Step-by-step explanation:
the answer is 3/4 i think but i may be wrong
means the nth term is 4 times the previous term
first term is 0.5
means the next one is 0.5 times 4 or 2
hum, geometric sequence
we can write it as
where
is the nth term
is the first term
is the common ratio (what you multiply each term by to get the next term)
is which term
so first term is 0.5
common ratio is 4
so therfor
answer is E
