First blank: not random Because he sent it to the top 5 students. Not random students throughout the grade.

second blank: I would guess not valid because it was not a random sample.

So i know how to do this but.... im confusing my self >n< please help me

ASHA 777 [7]

Answer:

see the attached graph

Step-by-step explanation:

When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).

x +3y = -3

Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:

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

The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.

map of a city uses the scale 1 cm equals 50 m. On the map, South Street is 25 cm long. If there is a traffic cone at the start

aivan3 [116]

Answer:

125 traffic cones

Step-by-step explanation:

In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:

$\frac{centimeters}{meters}=\frac{1}{50}=\frac{25}{x}$ , where 'x' is the number of meters

cross-multiply: x = 25(50) or x = 1250 m

Since there is a cone every 10 m, we can divide the total number of meters by 10:

1250/10 = 125 cones

For a circle with a diameter

meriva

Answer:

The measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°

Step-by-step explanation:

Here, the diameter of the circle = 6 m

Diameter = 2 x RADIUS

So, radius = D / 2 = 6 / 2 = 3 m

Also, the length of the arc = ( $\frac{5}{2} \pi$ ) meters

Putting π = 3.14, we get

The length S of the arc = $\frac{5}{2} \times (3.14) = 7.85$

or, S = 7.85 m

Let us assume the arc subtends angle Ф at the center of the circle.

⇒ S = r Ф

or, Ф = $\frac{S}{r} = \frac{7.85}{3} = 2.61$

⇒Ф = 2.61 radians

Now, 1 Radian = 57.2958 Degrees

⇒ 2. 62 Radian = 2.61 x ( 57.2958 Degrees) = 149.542 °

or, Ф = 149.542°

Hence, the measurement of the angle subtended by an arc with a length of 5/2 pi meters is 149.542°
