Katen [24]3 years ago
3 0

Answer: 0.5

Step-by-step explanation:

Given

There are 3 blue and 1 yellow marble

The chance of picking two marble out of 3 is ^3C_2

The total no of ways of picking 2 marbles out of 4 is ^4C_2

Therefore, the probability of picking 2 blue marbles

\Rightarrow P=\dfrac{^3C_2}{^4C_2}\\\\\Rightarrow P=\dfrac{3\times 2}{4\times 3}\\\\\Rightarrow P=\dfrac{1}{2}

True or false, y - 3 = -2 (x + 4) written in slope intercept form looks like y = -2x - 5
marysya [2.9K]

Answer:

The line you're looking for is parallel to y = 3x – 9, so it also has a slope of 3. Thus, you can rule out ... Here's what your work should look like: y = mx + b 0 = 3(–3) + b 0 = –9 + b 9 = b Now that you know both the slope and the y-intercept for this line, you can write the equation in the slope-intercept form: y = mx + b y = 3x + 9 The correct answer is Choice (C). What is the equation of a line that passes through the point (0, 3) and is perpendicular to y = 8x + 5? (F) y = 8x (G) y = 8x + 3 (H) (J)

Answer:

6

Step-by-step explanation:

On the fourth day, there were b^3 beads and 216 beads on the belt, which means b^3 = 216. Taking the cube root of both sides, we have b = 6, which means there were 6 beads on the belt on the first day.
