Answer: Y=-1/2x +11
-1/2 is the slope and 11 is the y-intercept
Answer:
252 calories burned in 1 hour.
Step-by-step explanation:
She burns 756 calories in 3 hours.
She burns x calories in 1 hour
756/3 = x/1
756/3 = x
252 = x
So she burns 252 in 1 hour.

Answer with explanation:</h2>
The confidence interval for population mean is given by :-

, where
is the sample proportion, n is the sample size ,
is the critical z-value.
The values needed to calculate a confidence interval at the 99% confidence level are :
Given : Significance level : 
Sample size : n=450
Critical value : 
Sample proportion: 
Now, the 99% confidence level will be :

Hence, the 99% confidence interval is 
Answer:
A
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles.
Call the inside angle D
A+ B + D = 180 sum of the angles of a triangle is 180
C+D = 180 since the form a straight line
Solving for D
D = 180-C
Substitute this into the first equation
A+ B + 180-C = 180
Subtract 180 from each side
A+ B + -C =0
Add C to each side
A + B = C
This proves the theorem
Answer:
I'm pretty sure it's A since B,C,and D wouldn't make sense.
