Answer:
b. 0.38.
Step-by-step explanation:
You either win a prize or you don't. There are only 2 possibilities so the probability of not winning a prize = 1 - 0.62 = 0.38.
Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have

This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square


Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is the point (6,-31)

Answer:
(a) 31.5 in²
Step-by-step explanation:
The area of a rhombus is half the product of the lengths of the diagonals.
A = 1/2(d1)(d2)
A = (1/2)(7 in)(9 in) = 31.5 in²
There are 31.5 in² of space in the rhombus for engraving.
Then there would be 9 girls and 23 boys
Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Find two points of each line
Line A (-2, 0) (-1, 2)
Line B (-1. - 5) (-6, 0)
2.- Find the slope and equation of each line
Line A


m = 2
y - 0 = 2(x + 2)
y = 2x + 4
Line B


m = -1
y - 0 = -1(x + 6)
y = -x - 6
3.- Find the inequalities
Line A, we are interesteed in the lower area of the line, so the inequality is
y ≤ 2x + 4
Line B, we are also interested in the lower area of the line so the inequality is
y ≥ - x - 6
