(a) Find the mean number of registered vehicles per California household.

Answer:

____vehicles

(b) Find the median number of registered vehicles per California household.

Answer:

___vehicles

**Answer:**

**1). Mean = 2.275**

**2). Median = 2 vehicles**

**Step-by-step explanation:**

From the given table,

Number of vehicles (x) Frequency (f) (f)×(x) Cumulative freq.

0 11 0 11

1 52 52 63

2 66 132 129

3 35 105 164

4 19 76 183

5 12 60 195

6 5 30 200

[tex]\sum (f\times x) = 455[/tex]

Number of households = 200

Mean = [tex]\sum \frac{f.x}{n}[/tex]

= [tex]\frac{455}{200}[/tex]

= **2.275**

Median = value of [tex]\frac{(n+1)}{2}th[/tex] observation

= value of [tex]\frac{201}{2}th[/tex] observation

= Value of 100.5th observation

= Since 100.5th observation lies in the row of cumulative freq. = 129

= 2

Therefore, median number of registered vehicles per California household

= **2 vehicles**

Hello!!! Princess Sakura here ^^

**Step-by-step explanation:**

So first you should remember that....

[tex]a^{2} +b^{2} =c^{2}[/tex]

then you should plug in...

[tex]8^{2}+16^{2}[/tex]

that should equal...

[tex]c^{2}=320[/tex]

Then you should solve the equation now by doing the inverse of the square which is the square root of both sides...

[tex]\sqrt{c^{2} } =\sqrt{320}[/tex]

[tex]c=17.88854382...[/tex]

Then you have to round it to the nearest tenths, which'll give you...

**Answer:**

see below

**Step-by-step explanation:**

shape LNMP is :

translated as 0,-7 flip of mirrored along y-axis reflected imaged is ABCD as givenJody and her friends are playing a game in which the person who scores closest to zero points after three rounds wins! Jody's friend Robyn scored 5 points in the first round, lost 8 points in the second round, and scored 4 points in the third round. Jody scored 10 points in the first round and lost 4 points in the second round. What will Jody need to score in the third round to win the game? (3 points)

**Answer:**

Jody needs to lose the third round by 6 points to win the game.

**Step-by-step explanation:**

The rule of the game is the person **who scores closest to zero points** after three rounds win.

Robyn scored 5 points in the first round, lost 8 points in the second round, and scored 4 points in the third round.

So, total points for Robyn = 5-8+4=1

So, the magnitude of the closeness of Robyn's score from zero

=|1-0|=1

Jody scored 10 points in the first round and lost 4 points in the second round.

Let Jody score x point in the third round.

Total points for Jody= 10-4+x=6+x

So, the magnitude of the closeness of Jody's score from zero

=|6+x-0|=|6+x|

The condition for Jody to win the game is his points must be closer to zero than Robyn's points, i.e

|6+x|<1

Case 1: If [tex]x\geq -6[/tex],

6+x<1

[tex]\Rightarrow x<-5[/tex], which is not possible for this case.

Case 2: If [tex]x\leq -6[/tex],

-(6+x)<1

[tex]\Rightarrow x+6>1[/tex]

[tex]\Rightarrow x>-5[/tex]

For this case [tex]x= -6[/tex] is the only possibility.

So, Jody must score -6 in the third round to win the game. i.e Jody needs to lose the third round by 6 points.

Which of the following is equal to the expression listed below?

24 + 18

A.

6 + (4 × 3)

B.

6(4 + 3)

C.

(6 + 4)(6 + 3)

D.

(6 × 4)(6 × 3)

The answer is D because 6•4 is 24 and 6•3 is 18

Hope this helps :)

Hope this helps :)

**Answer:**

B

**Step-by-step explanation:**

Its not (A) because the outcome is 24 x 18

Its not (C) because that would be (10)(9) which is the same as multiplication

Its not (D) because that would be (24)(18) which again is multiplication

We are looking for addition of 24 and 18 which is B

6 x 4= 24

6 x 3=18

24+18

2x+4y+3z=6

x-2y+z=-5

-x-3y-2z=-7

solve for x,y,z

**Answer:**

**x = -7 2/3, y = 1 1/3 and z = 5 1/3.**

**Step-by-step explanation:**

2x+4y+3z=6 .....** 1**

x-2y+z=-5 .....**. 2**

-x-3y-2z=-7 ......**.3**

Add equations 2 and 3 to eliminate x:

-5y - z = -12 .....**4**

Multiply equation 2 by - 2:

-2x + 4y - 2z = 10

Add this to equation 1:

8y + z = 16 ........** 5**

Now add equation 4 to equation 5:

3y = 4

**y = 4/3 = 1 1/3.**

Now find z by substituting for y in equation 4:

-5(4/3) - z = -12

z = 12 - 20/3

**z **= 36/3 - 20/3 =** 16/3 = 5 1/3.**

Finally, we find x by substituting for y and z in equation 1:

2x + 4*4/3 + 3*16/3 = 6

2x = 6 - 16/3 - 16

2x = 18/3 - 16/3 - 48/3 = -46/3

**x = 23/3 = 7 2/3.**

A ramp is 50 feet long and has a 6° incline. A second ramp is 30 feet long and runs parallel to the first ramp. To determine the vector representing the shorter ramp, what scalar must be multiplied to the vector representing the first ramp? a scalar less than –1 a scalar between –1 and 0 a scalar between 0 and 1 a scalar greater than 1

**Answer:**

a scalar between 0 and 1

**Step-by-step explanation:**

i just took the test on EdG. :)

To determine the **vector** representing the **shorter ramp,** we must **multiply** the vector representing the **first ramp** by a **scalar** between 0 and 1.

To answer the question, we need to know what **scalars** and **vectors** are

These are variables that have only **magnitude.**

These are variables that have both **magnitude** and **direction.**

Now since the **first ramp** is 50 feet long and has a 6° incline and the **second ramp** is 30 feet long and runs parallel to the first ramp. We see that the **magnitude** of the first ramp is **greater than** that of the **second ramp. **

So, to obtain a **vector** representing the second ramp from that of the first ramp, we multiply by a scalar which will be between 0 and 1, since, the **magnitude** of the first ramp vector is **greater than** the **magnitude** second ramp vector.

So, to determine the **vector** representing the **shorter ramp,** we must **multiply** the vector representing the **first ramp** by a **scalar** between 0 and 1.

A−2

B−1

C2

D1

**Answer:**

1) B - 5/4

2) A. The cost of delivery is $120

3) C 2

**Step-by-step explanation:**

1) The given parameters are;

The demarcations on the x-axis = -10 to 10

The demarcations on the y-axis = -10 to 10

The coordinates of two points on the graph are (0. 7), and (4, 2)

The slope, m, of a graph is given by the following equation;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Given that (x₁, y₁) = (0. 7) and (x₂, y₂) = (4, 2), we have;

[tex]Slope, \, m =\dfrac{2-7}{4-0} = -\dfrac{5}{4}[/tex]

The slope, m = -5/4

Taking B. as = -5/4

2. The given information are;

The nature of the cost of delivery of crushed stone = Cost of delivery, A

The function, f, for the cost of crushed stone of mass, x is the cost C, f(x) = C = m × x + A

Whereby the the graph of the total cost of the crushed stone is a straight line graph, we have;

C = m × x + A

At the y-intercept, x = 0, we have;

C[tex]_{(y-intercept)}[/tex] = m × 0 + A

C[tex]_{(y-intercept)}[/tex] = A = Cost of delivery

The points on the line are;

(0, 120) and (400, 134), therefore, the slope, m, is given as follows;

[tex]Slope, \, m =\dfrac{134-120}{400-0} = \dfrac{14}{400} = 0.035[/tex]

We have;

(C - 134) = 0.035×(x - 400)

C = 0.035·x - 14 + 134 = 0.035·x + 120

C = 0.035·x + 120

At the y-intercept, x = 0, we have;

C[tex]_{(y-intercept)}[/tex] = 0.035 × 0 + 120

C[tex]_{(y-intercept)}[/tex] = 120 = Cost of delivery

Therefore, the cost at the y-intercept = The cost of delivery = $120

3. The coordinates of points on the graph are;

(0, 1) and (2, 0)

The slope, m = (0 - 1)/(2 - 0) = -1/2

The equation of the line in point slope form is given as follows;

(y - 0) = -1/2 × (x - 2)

y = -x/2 + 1

The x-intercept occurs at the point y = 0, which is presented as follows;

0 = -x/2 + 1

-x/2 = -1

x = -1 × (-2) = 2

x = 2

Therefore, the y-intercept occurs at x = 2.

Consider the function rule: y = 9x – 7

What is the value of y when x=4?

What is the value

The value of y is 29

Since x=4, put 4 in 9x

y = 9(4) - 7

y = 36 - 7

y = 29

Since x=4, put 4 in 9x

y = 9(4) - 7

y = 36 - 7

y = 29

The given expression is (x - 8)(x + 4)

a) For what value of x will the expression be equal to zero

(x - 8)(x + 4) = 0

This can be split into:

**x - 8 = 0**

That is, x = 8

**x + 4 = 0**

That is, x = -4

The expression** (x - 8)(x + 4) equals to zero** when **x = -4 or x = 8**

b) Write this product as an equivalent trinomial.

A **trinomial** is a polynomial **expression** with **three terms**
