Ok: the question is basically asking what is the percentage of the black marbles he had pulled with replacements. You look at the graph and count how many black marbles he pulled,6, and then find the total of marbles he pulled after the experiment ,20. So, you take (6/20) which then gives you an answer of .3 which is a 30%.
To solve this, we'll use the trigonometric function called cosine.
The cosine of an angle -in a right triangle-, is equal to the side adjacent to the angle over the hypotenuse of the triangle.
Given the angle 41, its adjacent side is
and the hypotenuse is 55, so:
We solve for
:
The answer is 41.51.
64 = 22 + .25m
Subtract 2w from both sides.
42 = .25m
Divide both sides by .25
168 = m. This means after renting the car, it was driven for 168 miles.
The line graph is unsuitable for her purposes because it does not show adequately the comparison of the expenses.
Line graph is used to show the increase/decrease of a particular variable.
Bar graph is a more adequate format to create a visual representation.
Answer: Two separated circles, one called X and the other called Y.
(so there is no element of the set X that is also in the set Y)
Step-by-step explanation:
"No X are Y"
This means that there is not a single element in the set X that is also in the set Y.
So in an Euler diagram, you can represent this as two circles, one called Y and other called X, where the circles do not intersect or touch at any point.
This particular case is represented similarly to how you would represent it in a Venn diagram
