Find the mode.19, 1, 17, 19, 3, 20, 5, 2


A. 10.75
B. 11
C. 19
D. 20

Answers

The answer is C. 19

Rearrange the series from the lowest to the highest value:
1, 2, 3, 5, 19, 19, 20

The mode is the value that occurs most frequently. Number 19 is found twice, so it is the mode.
The correct answer is C. 19

This is hard for me, can someone please help? Loren solved the equation 10 = StartFraction 19 Over 9 EndFraction (149) + b for b as part of her work to find the equation of a trend line that passes through the points (1, 130) and (10, 149). What error did Loren make? She should have solved 10 = StartFraction 9 Over 19 EndFraction (149) + b for b. She should have solved 1 = StartFraction 19 Over 9 EndFraction (130) + b for b. She should have solved 149 = StartFraction 19 Over 9 EndFraction (10) + b for b. She should have solved 130 = StartFraction 9 Over 19 EndFraction (1) + b for b.

Answers

The solution is, the equations of line passes through two points:(1,130), (10.149) is:

149=19/9 (10) +b

130=19/9(1)+b

What is a straight line?

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

here, we have,

for Loren to find a line passes through two points:(1,130), (10.149)

1) find slope: m=y2-y1/x2-x1 =149-130/10-1=19/9

m=19/9

to find b in the equation y=mx+b for point (1,130)

y=130, x=1, m=19/9

130=19/9(1)+b

for point (10,149)

149=19/9 (10) +b

you have two options

Hence, The solution is, the equations of line passes through two points:(1,130), (10.149) is:

149=19/9 (10) +b

130=19/9(1)+b

Find the length x in the triangle. Express your answer in simplified radical form. Side 1=10. Side 2=8. Side 3=x

Answers

There's not enough information given to find a unique answer. 
With sides of 10 and 8, an infinite number of different triangles
can be built, each with a different third side.  The third side
can be any length between 2 and 18 .

There may be a picture that goes along with this question, with some
more information in the picture than what has been given here. Like
for example, it may be some special kind of triangle.
