Answer:
I'm pretty sure it's the last one that is incorrect
Step-by-step explanation:
Given:
To find:
Select the true statements from the given options about the given value.
Solution:
We have,
It can be written as
![[\because \log(ab)=\log a+\log b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%28ab%29%3D%5Clog%20a%2B%5Clog%20b%5D)
Clearly, the value of x lies between 4 and 5. So, 
and 
.
Therefore, the correct options are C and D.
Answer:
The first quartile, Q1, is the median of {3, 5, 7, 8}. Since there is an even number of values, we need the mean of the middle two values to find the first quartile: .
Step-by-step explanation:
Example 1: Find the first and third quartiles of the set {3, 7, 8, 5, 12, 14, 21, 15, 18, 14}
Answer:
1 pear = $0.75; 1 orange = $0.65
Step-by-step explanation:
(1) 3P + 4O = 4.85
(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)
3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms
6O = 3.90 Divide each side by 6
O = $0.65 Substitute into Eqn (1)
3P + 4×0.65 = 4.85
3P + 2.60 = 4.85 Subtract 2.60 from each side
3P = 2.25 Divide each side by 3
P = $0.75
Oranges cost $0.65 each and pears are $0.75 each
