Finish this sentence: To determine proportionality from a graph

2 answers:

8 0

Because the constant of proportionality only exists for linear relationships, you can use the graph of a proportional relationship to figure out what your constant of proportionality is.

To find your constant of proportionality from your graph, you are basically finding the slope of your line. You want to locate two points with easy coordinates, then you count the number of squares you need to go up followed by the number of squares needed to go to the right to get from your first point to the second point, your first point being to the left of your second point.

Which is the difference of 21 1/4 - 18 2/4? A:2 1/4. B:2 2/4. C:2 3/4. D:3 1/4.

seropon [69]

Answer:

2 3/4 C

Step-by-step explanation:

$(21+\frac{1}{4})-(18+\frac{2}{4})\\=21-18+\frac{1}{4} -\frac{2}{4} \\=3-\frac{1}{4} \\=\frac{12-1}{4} \\=\frac{11}{4} \\=2\frac{3}{4} \\or\\21\frac{1}{4} -18\frac{2}{4} \\=\frac{85}{4} -\frac{74}{4} \\=\frac{85-74}{4} \\=\frac{11}{4} \\=2\frac{3}{4}$

Find the solutions to the equation.

Kitty [74]

You can write the equation using conventional symbols as
3x^2 - 2x - 5 = 0

You can recognize that the middle coefficient is equal to the sum of the other two, so those two coefficients can be used to factor the equation.
(1/3)(3x +3)(3x -5) = 0 . . . . . put the coefficients in the form (1/a)(ax + ...)(ax + ...) (x+1)(3x-5) = 0 . . . . . simplify

The solutions are the values of x that make one or the other of the factors equal to zero.
x = -1
x = 5/3

There are red, yellow, blue and green counters in a bag. The probability of picking red is 0.25. The probability of picking yell

aev [14]

Answer:

The probability of picking a green is 0.4

Step-by-step explanation:

Mathematically, when we talk of the highest possibility an event can have, we have the answer as 1

Hence, when we add up all the probabilities, it is expected that we arrive at a value equal to 1

Thus, the probability of selecting each individual colors add up to 1

since we have the probability of three colors, the probability of the fourth will be the sum of the others subtracted from 1

we have the probability of picking a green as;

1 - 0.25 - 0.15 - 0.2 = 0.4
