The vertical line graph shows how often each number on a standard dice comes up. What percentage of rolls were a 6?

Novay_Z [31]

Answer:

21%

Step-by-step explanation:

Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.

The graph compares the number of filled tables at a party with the number of party guests. Which information tells you that the

Galina-37 [17]

Answer:

Step-by-step explanation:

A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.

To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.

For instance:

$y=2x$

According to this function we can easily check a proportional relationship among its points:

$(1,2), (2,4), (4,8), (6,12), ...$

$k=\frac{y}{x}=\frac{2}{1}=\frac{4}{2}=\frac{12}{6}\Rightarrow k=2$

Sketch the curve given by the set of parametric equations. x=t^2+4 y=t/5 +8

dangina [55]

Answer: see attached graph

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

Choose values for t and plug them into the x equation and y equation to find the x,y coordinates.

Usually there is an interval provided. Since you did not specify an interval, I chose to use [-2, 2].

$\begin{array}{c||c|c||c}t&x&y&(x,y)\\-2&8&\frac{38}{5}=7.6&(8,7.6)\\\\-1&5&\frac{39}{5}=7.8&(5,7.8)\\\\0&4&\frac{40}{5}=8.0&(4,8.0)\\\\1&5&\frac{41}{5}=8.2&(5,8.2)\\\\2&8&\frac{42}{5}=8.4&(8,8.4)\end{array}$

I don't know what it means by an obtuse angle. I have to choose math because I don't see a subject for shapes and stuff.

kozerog [31]

Answer:

Angle <em>ADE</em> is an obtuse angle.

Step-by-step explanation:

An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).

DEFG is a cyclic quadrilateral. If ∠E = 27°, find ∠G.

Mars2501 [29]

For a cyclic quadilateral, the combination of opposite angles = 180°. So <G is opposite to <E so G must be 153°
