Answer:

15.0 units

Step-by-step explanation:

Here, we want to get the distance between the two points as follows;

CD = √(x2-x1)^2 + (y2-y1)^2

So we have;

CD = √(7+8)^2 + (-5+4)^2

CD = √225+ 1 =

CD = √(226

CD = 15.0 units

Question six about significant figures, please help!

belka [17]

rules to find :- 1 All non zeroes number are significant

2 if zero proceeding the decimal point also work as non zero figure

3 zero are following the decimal point and proceeding the first non zero digit

4 Zero in between 2 non zero digits are also significant

5 if 1 zero follow the decimal point

790 :- 2 significant figures

0.0391 :- 3 significant figures ( follow 3 rule)

81.05 :- 4 significant figures ( rule 4)

0.000001 :- 1 significant figure

8546 :- 4 significant figures

79.0 :- 3 significant ( rule 5)

Find the solution to the system of equations. You can use the interactive graph below to find the solution. { y = x − 4 y = 4 x

kumpel [21]

ANSWER

$x=-2,y=-6$

EXPLANATION

First equation:

$y = x - 4$

Second equation:

$y = 4x + 2$

Let us equate the two equations and solve for x.

This implies that;

$4x + 2 = x - 4$

Group similar terms to obtain:

$4x - x = - 4 - 2$

Simplify:

$3x = - 6$

Divide both sides by 3

$x = - 2$

Put x=-2 into any of the equations.

I will put x=-2 into the first equation:

$y = - 2 - 4$

This implies that,

$y = - 6$

Which graph most likely shows the experimental probability histogram of X based on 100 data points?

Archy [21]

Answer:

see attached

Step-by-step explanation:

Based on 100 trials, we don't expect the experimental probability to deviate much from the theoretical probability. The scales on the attached graphs are hard to read, but you want to choose the graph that ...

has bars that total 100 in their length
has bars that are approximately .50, .25, .17, .08 in height, corresponding to the area fraction

We think the appropriate choice may be C, but we cannot tell for sure.
