Answer:
20
Step-by-step explanation:
using the rule of logarithms
loga + logb = logab
then
4 + 5
= (4 × 5)
= 20
Answer:
6.4
Step-by-step explanation:
Given the data:
15, 25, 10, 2, 8
Sample size, n = 5
The mean, m of the data above is :
(15 + 25 + 10 + 2 + 8) / 5
= 12
The mean absolute deviation:
|x - m| / n
|15 - 12| + |25 - 12| + |10 - 12| + |2 - 12| + |8 - 12|
(3 + 13 + 2 + 10 + 4) / 5
= 32 / 5
= 6.4
Answer:
1/2
Step-by-step explanation:
it's positive so its absolute value is the same just like a positive whole number
note: the absolute value of a negative fraction is tricky, but that's not important here
The probability is 8/18 or 44%.
Since there are 3 sculptors and 5 photographers, and the question is asking for either a sculptor or photographer, you add them together. There are a total of 18 artists, and the probability is the chance of a certain thing happening over the total amount of things that can happen (i.e. a coin landing on heads is 50%).
The answer would be 8/18.
9-2=7
3+4=7
9 plus 2 equals 7 and 3 plus 4 also equals 7.
