Answer:
Step-by-step explanation:
1a) the y intercept, or 20
b) from 0 weeks to 1 week the difference is 10
c) its y=mx+b m is the slope(difference) and b is the y-int so y = 10x+20
2a) the y int, is the same as the x(number of games played) being zero, so here it is 25
2b) after 3 games it was a loss of 1.50 !!! IMPORTANT !! after THREE weeks, so its 1.5/3=0.5 amount on card per week
2c) (ref 1c) but with that same formula/equation - we get y=0.5x+25
The point was reflected over the y -axis and translated up 4 units.
The point was translated left 10 units and up 4 units.

Answer with explanation:</h2>
Formula for plus-four confidence interval :

, where n= Sample size.
= Sample proportion and 
z* = Critical z-value.
Let p be the proportion of puppies area found with early hip dysplasia.
As per given , we have
n= 42

Since confidence interval is not given , so we assume it as 95% .
z-critical value for 95% confidence is 1.96.
Then, the required confidence interval will become :

Hence, the plus four confidence interval for p = (0.0484, 0.256)
Interpretation: We are 95% sure that the true proportion of puppies area found with early hip dysplasia lies in (0.0484, 0.256).
Answer:
12 cm²
Step-by-step explanation:
Use the area formula A = lw, where l is the length and w is the width:
A = lw
A = (3)(4)
A = 12
= 12 cm²
