Answer:
Using the slope formula with points (0,-1) and (-4,4)
Step-by-step explanation:
Step 1: find the points, (0,-1) and (-4,4)
Step 2: Insert plot points into <em>Slope formula: (tip: M means slope)</em>
m(slope)= -> m(slope)=
Step 3: <em>Solve:</em>
m(slope)=
Answer:
Slope is
or m =
OR (if your teacher wants the answer in decimal form rounded to the nearest 10th.) m = -1.3
Mean: Add all of the numbers together, then divide by how many numbers there are. So, your mean is 40.6 (Rounded to the nearest tenth)
Median: The middle number (when they are in order). So, your median is 44.
Mode: The mode is whatever number appears the most; however, since there are no repeating numbers, there is no mode for this data set.
Range: Range is the difference between the highest and lowest values of the data set. So, your range is 55.

Answer:
A) 70.5
Step-by-step explanation:
cos x = adjacent side/ hypotenuse
cos x = 10/ 30
cos x = 0.3
cos 70 = 0.3420
cos 71 = 0.3256
x = 70.5
Answer:
The coordinates are ( 4, -3).
Step-by-step explanation:
We can find the coordinates by solving the 2 equations
y = 1/4x-4
y = -1/2x-1
As both left sides of the equation are y we can say:
-1/2x-1 = 1/4x-4
-1/2x - 1/4x = -4 + 1
-3/4 x = -3
x = -3 * -4/3
x = 4.
- and y = 1/4(4) - 4 = -3.
