PLEASE HELP I GIVE 100 POINTS!!
balandron [24]

9514 1404 393

Answer:

  1.  b. The common difference is 0.39

  2.  no good answer (Zach's method is exponential; Victoria's is linear)

Step-by-step explanation:

1. The differences in mileage are ...

  24.39 -24 = 0.39

  24.78 -24.39 = 0.39

  25.17 -24.78 = 0.39

The common difference is 0.39.

____

2. Zach's monthly times are ...

  10, 20, 40, 80

The differences are ...

  10, 20, 40

The ratios are ...

  20/10 = 40/20 = 80/40 = 2

Zach's times have a common ratio, so are exponential.

__

Victoria's monthly times are ...

  35, 50, 65, 80

The differences are ...

  15, 15, 15

Victoria's times have a common difference, so are linear.

__

The choices are ...

  a. both exponential; common factor . . . . correct for Zach; not for Victoria

  b. Zach's is linear (has equal factor) . . . incorrect

  c. both exponential; common difference . . . incorrect

  d. Victoria's is linear . . . . correct for Victoria

Choice D describes Victoria's method. Choice A is correct regarding Zach's method, but incorrect regarding Victoria's.

Choices B and C are not self-consistent, so are incorrect on their face.

There is no good choice.

Using properties of parallelograms, RSTU is a parallelogram that has vertices R (-3,1), S (3,4), and T( 6,2(. What are the coord
ElenaW [278]

Answer:

(0, -1)

Step-by-step explanation:

A parallelogram is a quadrilateral (has four sides) in which opposite sides are parallel to each other. Also for a parallelogram, the opposite sides and angles are equal to each other.

Hence for parallelogram RSTU, RS // TU and RU // ST

Let the coordinate of U be (x , y). Two lines are parallel to each other if their slopes are equal, hence:

Slope of RS = (4 - 1) /[3 - (-3)] = 3/6 = 0.5

Slope of ST = (2 - 4) /[6 - 3] = -2/3

Slope of RU = (y - 1) /[x - (-3)] = (y - 1) / (x + 3)

Slope of TU = (y - 2) /[x - 6]

Slope of RU = Slope of ST

(y - 1) / (x + 3) = -2/3

3y - 3 = -2x -6

2x + 3y = -6 + 3

2x + 3y = -3                  (1)

Slope of RS = Slope of TU

0.5 = (y - 2) /[x - 6]

0.5x - 3 = y  - 2

0.5x - y = 1                  (2)

Solving 1 and 2 simultaneously gives:

x = 0, y = -1

Therefore the coordinates of U = (0, -1)

Complementary events must have a sum of 1.
Bas_tet [7]

This is a true statement.

Consider two events A and B. We say they are complementary if P(A)+P(B) = 1

This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.

---------

Example:

A = the event it rains

B = the event it does not rain

P(A) = 0.30 = 30% chance of rain

P(B) = 0.70 = 70% chance it does not rain

P(A)+P(B) = 0.30+0.70 = 1

So this shows the two events are complementary.
