Answer:
Step-by-step explanation:
- First, lets get rid of the fraction. I did this by multiplying both sides by
.
- We want to isolate
on one side of this equation. Let's put any values with on one side of the equation, and normal integers on the other.
- Divide both sides by
.
- If your teacher wants you to leave your final answer as an improper fraction, your final answer is this. If they want it to be a mixed number or decimal, your final answer will be:
Answer:
Yes
Step-by-step explanation:
A rational number can be expressed as a quotient of two integers. Therefore 78/10 = 39/5 = 0.78 represents a rational number between 7.7 and 7.9. Answer: 39/5
Answer:
y=mx+bx
Step-by-step explanation:
You could either use (7,19) or (9,29) to find the equation....
Y=mx+b
You plug in you x and y, then we are trying to solve for b
x=7, y=19
19=m(7)+b
7m+b=19
-7m -7m
b= 19 - 7m
Y=7m+1
The modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
<h3>Define the term adjusted r squared?</h3>
R-squared (R2) would be a statistical measure that quantifies the proportion of the variation explained from an independent variable other variables within a regression model for a dependent variable.
- R-squared describes how much the variance with one variable describes the variance of the other.
- So, if a model's R2 is 0.50, the model's inputs can explain roughly half of a observed variation.
- A score of 70 to 100 shows that a specific portfolio closely reflects the underlying stock index, whereas a score of 0 to 40 indicates a relatively poor correlation the with index.
- Higher R-squared scores also suggest that beta measurements are more reliable. The volatility of either a security or portfolio is measured by beta.
Thus, the modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.

Answer:
Yes ans = 27720. Total possibilities = C(4,1) * C(6,4) * C(11,6) = 27720.
