The answer is A. $12.60 :)
Answer:
1. No
2. No
3. Yes
4. No
5. Yes
6. No
Step-by-step explanation:
If you want to check if a graph is a function, do a vertical line test. For every vertical line, there should be only 1 point on the line if the graph is a function.
Y=-1
Move all terms containing x to the left side of the equation.
Subtract 3x from both sides of the equation.
2x-3x=−5
Subtract 3x from 2x
−x=-5
Multiply each term in -x=−5 by −1
Multiply each term in −x=−5 by −1
(-x) ⋅ -1=(-5) ⋅-1
X=(-5) ⋅-1
multiple -5 by -1
X=5
Since x=5 is a vertical line, the slope is undefined.
Undefined
The equation of a perpendicular line to
x=5 must have a slope that is the negative reciprocal of the original slope.
M perpendicular = -1/∞
The negative reciprocal of ∞ is 0
M perpendicular is 0
Since the slope for the perpendicular line is 0 ,the line is perpendicular to the y-axis. The equation of this line is of the form
y=c when c is any real number. The equation of the line at point (-2 ,1)
Y=-1

Answer:
435,307
Step-by-step explanation:
Given that :
p = 0.18
Zcritical = 99%
Error (E) = 1.5% = 1.5/100 = 0.0015
Sample size (n) can be obtained using the relation :
n = (Zcrit / E)^2 * (p * q)
q = 1 - p ; q = 1 - 0.18 = 0.82
Zcrit at 99% equals 2.576
n = (2.576 / 0.0015)^2 * (0.18 * 0.82)
n = (1717.3333)^2 * (0.1476)
n = 2949233.66328889 * 0.1476
n = 435306.888701440164
n = 435,307 samples
Let
x--------> The number of red marbles
y--------> The number of blue marbles
we know that
equation
equation
equate equation and equation
therefore
the answer is
The number of red marbles is
The number of blue marbles is
