Median = middle number
Total ten numbers so
median = (17 + b)/2
given median = 18
so
(17 + b)/ 2 = 18
17+b = 36
b = 36 - 17
b = 19
Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25
Mean = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
Given mean = 17
so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9
answer
a = 9
b = 19
The prefix that means hundredth is centi
Answer:
6
Step-by-step explanation:
66 / 6 =11
90/6 =15
11 & 15 prime to each other, so 6 is the answer.
The image would be an enlargement since K>1, and any K values greater than one is essentially enlarging the graph by that factor
Assume total = x
12% of x = 36
→ 12% * x = 36
→ 0.12x = 36
→ x = 300
so the answer is 300
