Answer:
140 coins.
Step-by-step explanation:
Let x be the total number of coins in Kate's collection.
We have been given that Kate has a coin collection. She keeps 7 of the coins in a box which is only 5% of her entire collection.
We need to figure out x such that 5% of x equals to 7. We can represent this information in an equation as:
Therefore, the total number of coins in Kate's collection is 140 coins.

Step-by-step explanation:
Given the parabolic equation is in the form of (y-k)²=4p(x-h), this is a horizontal parabola with a vertical directrix at x=h-p where (h,k) is the vertex and the focus is (h+p,k). Since p=2, then the directrix is x=3-2=1. The vertex would be (h+p,k) -> (3+2,2) -> (5,2). Refer to the graph.

Answer:
Midpoint is (0, -4)
Step-by-step explanation:
x-coordinate of midpoint = (-7 + 7)/2 = 0/2 = 0
y-coordinate of midpoint = (3 - 11)/2 = -8/2 = -4
Midpoint is (0, -4)
12 red marbles
20 green marbles
17 blue marbles
Total amount: 39 marbles
39 (total) - 12 (red) = 27.
John has a probability of 27/39 that he will not pick a red marble out of the bag.
If you want to simplify your fraction by dividing both numbers by 3 to make it even more accurate, an even better answer would be 9/13.
(so all you do is divide 27/3 and divide 39/3 aswell which gives you 9 and 13.)
