Enter your answer in the box.

Answer: graph 1 —> u-v

graph 2—> u-w

graph 3—> w-v

graph 4—> v-u

*Look at both pictures to make sure this is for your specific question

Step-by-step explanation: I got this right on Edmentum

Graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have vectors u, v, and w given in the picture:

u = <-2, -7>

v = <3, -4>

w = <5, 1>

= u - v

=  <-2, -7> - <3, -4>

= <-5, -3>

= u - w

=  <-2, -7> - <5, 1>

= <-7, -8>

= w - v

=  <5, 1>  - <3, -4>

= <2, 5>

= v - u

= <3, -4> - <-2, -7>

= <5, 3>

Thus, graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.

Answer-

77

Step-by-step explanation:

i rounded 76.67% (which was the exact percentage of 46 out of 60)

2- 77%

Answer:

About 76.5% (77%)

Step-by-step explanation:

well start with the simple fractions. 40/60 is 2/3 which is 66.66666 repeating.

If we know it increased at least 5 more that is 45/60 which is 3/4, since 15 * 4 = 60, so 15 * 3 = 45.

We could say without getting too specific that every point will have about a 1.5 or more % increase since if it was out of 100 points every 1 question is +1 % and 50 points every question is +2 %. Since this is 60 it will be roughly about 1.6%

Ok the point is, about 76.5% (77%)

Answer:

t(s) is in the acceptance region. We accept H₀ we don´t have enough evidence to justify differences in the procedures

Step-by-step explanation:

Traditional procedure bring as μ  =  8,6 h

Sample Information:

Sample size   n  = 26

Sample mean  x  =  8,4

Sample standard deviation   s  = 1

With  n  = 26  unknown population standard deviation, and population with normal distribution we should use t-student test

then  n = 26      degree of freedom  df  =  n - 1    df  =  25

significance level 0,1  with that information we look in t-student table t (c) ( two tails test)

t(c) = - 1,708

Test Hypothesis

Null hypothesis                  H₀                 x =  μ

Alternative Hypothesis     Hₐ                 x ≠  μ

Alternative hypothesis indicates that the test should considered two tails

To calculate  t(s)

t(s)  =  (  x  -   μ ) / s/√n

t(s)  = ( 8,4  -  8,6 )/ 1/√26

t(s)  = - 0,2 *  5,09 / 1

t(s) =  - 1,019

Comparing |t(s)| and |t(c)|

1,019 < 1,708     |t(s)| <  |t(c)|

t(s) is in the acceptance region. We accept H₀ we don´t have enough evidence to justify differences in the procedures

Step-by-step explanation:

(((2•3x2) • y2) -  9xy) -  42

6x2y2 - 9xy - 42  =   3 • (2x2y2 - 3xy - 14)

The complete factorization of 6x^2y^2-9xy-42 is 3 (2x^2y^2 - 3xy - 14).

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

The given expression is

[tex]6x^2y^2-9xy-42[/tex]

= [tex](((2\times3x^ 2) \times y^2) - 9xy) - 42[/tex]

Answer:

Equally likely

Step-by-step explanation:

A coin has two sides, heads and tails, so if you flip it, you have a 50% chance to get heads and a 50% chance to get tails. 50% - 50% is an equal ratio, therefore having an equal chance of likelyhood to get heads.

Answer:

x=4

Step-by-step explanation:

Step 1: Subtract 7x from both sides.

11x−6−7x=7x+10−7x

4x−6=10

Step 2: Add 6 to both sides.

4x−6+6=10+6

The equation of the line shown in the graph is y = 3x + 3.

The equation of the line shown in the graph is determined by calculating the slope and y - intercept of the line as shown below.

The slope of the line is calculated as follows;

m = Δy / Δx

where;

m = ( 9 - 3 ) / (2 - 0 )

m = 6 / 2

m = 3

The  y - intercept of the line is the point where the line intersects y-axis.

c = 3

The general equation of a line is given as;

y = mx + c

So our equation of the line becomes;

y = 3x + 3

Step-by-step explanation:

√123 ≈ 11.0905 lies between 11 and 12.

__

Since you're familiar with your squares, you know ...

  11^2 = 121

  12^2 = 144

123 lies between 121 and 144, so √123 lies between 11 and 12.

Answer:

√193

Step-by-step explanation:

pathagorus theorem:

[tex]( {hyp})^{2} = ( {base)}^{2} + ( {perp)}^{2} [/tex]

hyp=x , base= 12 , perp= 7

subtitles all values in formula:

we get

x^2 = 12^2 + 7^2

x^2 = 144 +49

x= √193

The missing side of this right triangle is, 13.90 units.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The base of the triangle = 12

The perpendicular distance of the triangle = 7

Now, We know that;

Pythagoras theorem stated as;

⇒ Hypotenuse² = Base² + Perpendicular²

⇒ x² = 12² + 7²

⇒ x² = 144 + 49

⇒ x² = 193

⇒ x = √193

⇒ x = 13.90

Thus, The missing side of this right triangle is, 13.90 units.
