NO....... It is 25% spades and 75% are not spades
X-intercept can be found when y=0
y-intercept can be found when x=0
Plug in x=0 to find the y-intercept
-3(0) + 4y = -12
4y = -12
y = -3
Plug in y=0 to find the x-intercept
-3x + 4(0) = -12
-3x = -12
x = 4
The x-intercept is (4,0)
The y-intercept is (0, -3)
150 * 8 = $1,200
150 / 2 = $75
$1,200 + $75 = 1275

Answer:
1.05
Step-by-step explanation:
Following instructions, we have ...
Z = (X -μ)/σ
Z = (180 -159)/20 = 21/20
Z = 1.05
The Z-score associated with the value 3 minutes is 1.05.

Answer:
"f(x) = (x + 3)(x – 7)"
Step-by-step explanation:
If the vertex is (h,k), then the quadratic is can be written in the form:
y = a (x-h)^2 + k
So it will be:
y = a(x-2)^2 - 25
Now, to find a, we need the x-intercept (which is 7), so we plug in 7 into x and 0 into y and solve for a:
0 = a(7-2)^2 - 25
0 = a(5)^2 - 25
0 = 25a - 25
a = 1
THus, we can write:
y = (x-2)^2 - 25
Expanding this, we get:
y = x^2 -4x + 4 - 25
y = x^2 - 4x - 21
y = (x-7)(x+3)
THis is correct answer.
