Answer:
a)
b)
c)
Step-by-step explanation:
a)To the left of z = 0.72.
For this case the shaded area is on the figure 1 attached.
And we can find the area with the normal standard table of with the following excel code:
=NORM.DIST(0.72,0,1,TRUE)
b)To the right of z = 0.15.
For this case the shaded area is on the figure 2 attached.
And we can find the area with the normal standard table of with the following excel code:
=1-NORM.DIST(0.15,0,1,TRUE)
c)Between z = -1.40 and z = 2.03.
For this case the shaded area is on the figure 3 attached.
And we can find the area with the normal standard table of with the following excel code:
=NORM.DIST(2.03,0,1,TRUE)-NORM.DIST(-1.40,0,1,TRUE)
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
