A girl has 20 marbles
10 are red, 7 are blue, and 3 are green
If she picks 5 marbles, without replacing them, what are the chances all 5 are red?
10/20 * 9/19 * 8/18 *7/17 * 6/16
1/2 * 9/19 * 4/9 * 7/17 * 3/8
1/2 * 1/19 * 3/2
1/76
Answer:
Jane is right. 6 minus the number equals four
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Make a commone demonatore my multiplying.
When the long hand points at a number that's the hour when the short hand points at a number you're counting by 5s. so 1=5, 2=10, 3=15, 4=20, 5=25, 6=30, 7=35, 8=40, 9=45, 10=50, 11=55, and when you reach 12 a new hour starts.
hope this helps please mark me brainliest
Slope formula is y=mx+b. m is the slope and b is the y-intercept. You can plug the coordinates that are given, (-3,-3), to find the y-intercept.
y=-3/4x+b is the equation you have so far. Plug in (-3,-3):
-3=-3/4(-3)+b
Multiply -3/4*-3.
-3=9/4+b
Subtract 9/4 from both sides.
-21/4=b
Equation: y=-3/4x-21/4
-21/4 equals -5.25, so your y-intercept would be (0,-5.25). That is the first point that you can plot on your graph.
After this, to graph the rest of the equation, you need to use your slope, -3/4. Every point will be down 3, right 4 from the one before it. In this case, your next point to graph would be (4,-8.25). You can also find what the coordinates would be in the opposite direction by going up 3, and left 4 from the original y-intercept. In this case, the coordinates would be (-4, -2.25)
Graph the points: (0,-5.25), (4,-8.25), and (-4, -2.25). Connect all the points to form your line. Normally, graphing two or three points should be enough!
I hope this helps :)
