First you want to find out how many marbles you start with so it'd be 8+7=15. You start with 15 marbles. If you randomly drew a blue marble, it'd be 8:15 and if you drew a yellow marble without replacing the blue one, it'd be 7:14 or 50-50 chance.
Answer:
24
Step-by-step explanation:
If this is an answer 24 because when there were 50 tickets sold there were 12 so when there is 100 tickets sold you double 12 to get 24
Hope this makes since and please do not come after me if this is wrong.
Answer:
3.75
Step-by-step explanation:
1.25 times 3
Answer: 471in^3
Explanation:
Formula : V = pi x r^2 x h
Explanation:
r = d/2 = 10/2 = 5in
pi = 3.14
h = 6
Put this value in the formula:
V = 3.14 x 5^2 x 6
V = 3.14 x 25 x 6
V = 3.14 x 150
V = 471 in^3
The correct answer is y = -2x + 16. In slope-intercept form, the formula is y = mx + b, where m is the slope and b is the y-intercept, or the place where the line crosses the y-axis. For this line, the y-intercept is positive 16, because the line crosses the y-axis at 16. Therefore, we know that the equation is y = mx + 16. Now, we just need to find the slope. By counting squares, we can see that the line goes down 4 and right 2. You can check this by taking two points on the line and subtracting them. For instance, the line goes from y 16 to y 12, which has a 4 unit difference. Therefore, the line goes down 4. It goes from x 0 to x 2, meaning that there is a difference of 2 between them, and, since the line is going right, the 2 is positive. Since slope = y/x, the slope is -4/2, or -2. Therefore, the slope is -2.
Adding all this together, the slope in slope-intercept form is y = -2x + 16.
Hope this helps!
