Answer:
B
Step-by-step explanation:
The ratio of blue marbles and yellow marbles is 1:1,means that the number of blue and yellow marbles are the same.
So,you can remove answer A and C from your options.
Next,the ratio of blue marble to red marble is 2:3.
This shows that the number of red marble is more than blue marble and automatically more than yellow marbles bcs number of blue and yellow marbles are the same
So the most accurate and correct answer is B.
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 2 ) and (x₂, y₂ ) = (2, - 4) ← 2 points on the line
m = = = - = -
and using (a, b ) = (2, - 4 ) , then
y - (- 4) = - (x - 2) , that is
y + 4 = - (x - 2) → C
Answer:
(0, 15/6) (15/7,0)
Step-by-step explanation:
Just set the other value to 0 and you can very quickly solve these.
¹/9
Step-by-step explanation:
Of the total marbles (4 + 2 + 3) = 9 , the number of blue marbles is 2. The probability of drawing out a blue marble is therefore ²/9
A coin has two sides – therefor two possibilities in a toss (heads or tails). The probability of tossing either is therefore ½.
We MULTIPLY two probabilities when both conditions need to be satisfied at the same time. Therefore;
²/9 * ½ = ²/18
= ¹/9
