Answer:

Step-by-step explanation:
Standard form:

Vertex form:

(h, k) is the vertex
x is the coordinate of the vertex
To find x use the formula:


a=1
b=-2
c=-6
Substitute:

Substitute x in equation:

h=1
k=-7
Substitute h, and k into the vertex formula:

You need to find the probability of Heads, Heads, Heads in 3 tosses;
P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one
P(HHH)=1/8
Therefore, the probability of flipping 3 heads on a fair coin is 1/8

Answer:
80%
Step-by-step explanation:
Original price =$75.00
Sale price =$60.00
The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.
So % discount = $60.00/$75.00 x 100%
0.8 x 100%
80%
Janelle got the dress on a discount of 80%.
This is so because she got the dress for a price less than the original price
