Answer:
D. No, Jacob is not correct. The median amount he makes is $84.00 in a day.
Step-by-step explanation:
In this case, the mean is not the best measure of this data.
We can see that there is one value lower than the rest, $58. This brings the mean down.
With the value of $58, the mean is $80.70. If we were to take this value out, the mean would be $85.20, which is higher.
Since the mean is brought down by this value, we should use the median. The median of this data set is $84.
Answer:
An isosceles triangle is one with 2 sides of the same length.
As far as I can find, there are 6 different mom congruent triangles.
Answer:
y = - 3x - 3
Step-by-step explanation:
the equation of a linear function in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table
m =
=
= - 3
y = - 3x + b ← is the partial equation
To find b substitute any other point from the table into the partial equation
using (2, - 9), then
- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3
y = - 3x - 3 ← linear relationship
11 skirts since you can use 3/4 on each yard of 9. Then you get a remander of 2, 3/4! 9 + 2 is 11.
