Answer: 
= 0.89
Step-by-step explanation:
Coefficient of determination is represented by . This tells us that how much of the variation in the dependent variable is explained by the independent variable.
It is the ratio of explained variation by the independent variables to the total variation in the dependent variable.
Hence,
Coefficient of determination = 
= 
= 0.89
∴ 89% of the variation in the dependent variable is explained by the independent variables.
Answer:
For non-negative integers yes, it's 10 symbols.
Step-by-step explanation:
The symbols are the digits! 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Please note, that to represent negative numbers we use an additional symbol - and a . for fractions. I'm pretty sure the question is about the basics of the decimal system and the ten digits though.
Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years
Option A is the correct method to find the age of Peter and Winnie.
Answer:
Each batch of scones needed 0.67 kg of flour
Step-by-step explanation:
16.45 - 6.4 = 10.05kg (remaining)
15 batches = 10.05kg
1 batch = 0.67kg
Answer:
c
Step-by-step explanation:
If data is skewed then the upper and lower half have different amount of spread. Here there is no proof to say that data is not spread around mean or there are outliers. Therefore we can't say that the distribution of wings dinners sales in not normal.
