Y-y1=m(x-x1)
for slope=m
for point (x1,y1)
slope for 2 points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
points
(2,0)
(-6,4)
(0-4)/(2-(-6))=(-4)/(2+6)=-4/8=-1/2
m=-1/2
could be
y-4=-1/2(x+6)
or
y=-1/2(x-2)
Answer:
Equal to 7
Step-by-step explanation:
The way I learned multiplication was with some sayings. "7 times 7 went out to dine, when they came back it was 49"
The formula for a diagonal of a rectangle is <span>√w^2+h^2, with w and h being the width and height. Plug in your numbers to get </span><span>√7^2+5.5^2. Simplify that into </span><span>√49+30.25, then to </span><span>√79.25. Use your calculator to get 8.9022. The diagonal is 8.9 feet.</span>
Point estimation includes the use of sample mean
to compute a single value which is to help as a "best
guess" or "best estimate" of an unidentified (fixed
or random) population parameter. Meaning the sample mean is the best
point estimate of the population mean. Therefore, the answer is 19.1 because
this is the sample mean in the problem.
