<h2>Answer:</h2>

The mean number of vehicles owned by the families in Class B is:

<h2>Step-by-step explanation:</h2>

We know that the mean id calculated as the average of the data entries.

Now for class B we make a frequency table as follows:

Number of vehicles(x) Number of families(y) xy

0 3 0

1 4 4

2 10 20

3 7 21

5 1 5

Total number of families= 3+4+10+7+1= 25

∑ xy= 0+4+20+21+5= 50

Hence, the Mean is:

$Mean=\dfrac{\sum xy}{Number\ of\ families}\\\\i.e.\\\\Mean=\dfrac{50}{25}\\\\i.e.\\\\Mean=2$

Can anyone tel me what y equals in standard form?

ss7ja [257]

Answer:

y = x^2 +6x +8

Step-by-step explanation:

The vertex is located at (-3, -1) and the graph rises 1 unit vertically for 1 unit away from the vertex. This means the scale factor is 1 and the vertex form equation can be written as ...

y = a(x -h)^2 +k . . . . . vertex form with scale factor a, vertex (h, k)

y = (x -(-3))^3 +(-1) . . . fill in the values we know

y = (x +3)^2 -1 . . . . . simplify signs

y = x^2 +6x +9 -1 . . . eliminate parentheses

y = x^2 +6x +8 . . . . . your equation in standard form

You are planning to plant a triangular garden in your backyard, as shown. You plan to put up a fence around the garden to keep o

Drupady [299]

Answer:

24 m

Step-by-step explanation:

The lenght of fencing needed is the sum of all sides the triangular garden represented on the coordinate grid.

The lenght of the triangular garden = 16 - 10 = 6 m

Lenght of the height = 8 - 0 = 8 m

Lenght of the hypotenuse can be calculated using coordinates of the two vertices of the ∆ that forms the hypotenuse lenght and also using the distance formula.

Coordinates of the two vertices = (10, 0) and (16, 8).

$distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$(10, 0) = (x_1, y_1)$

$(16, 8) = (x_2, y_2)$

$d = \sqrt{(16 - 10)^2 + (8 - 0)^2}$

$d = \sqrt{(6)^2 + (8)^2}$

$d = \sqrt{36 + 64} = \sqrt{100}$

$d = 10$

Length of fencing = 6 + 8 + 10 = 24 m

A line passes through (2, 4) and (-2, 2). Find the value of y if (6, y) lies on the line. Not sure how the 3 was brought into th

Marrrta [24]

Answer:

Well, that is simple. You first must find the slope of the line from the 2 given points by using the slope formula. Which is y2-y1/x2-x1. So 2-4/-2-2 which equals -2/-4 which is 1/2. So the slope is 1/2. Now we can use the slope intercept form which is y=mx+b to find the slope equation. So we plug in one the points, say (2,4) and get y=1/2x+3. So now we plug in (6,y) Since we know x we can find y. y=1/2(6)+3 which gives us y=6. So y is 6.
