A box contains different-colored marbles. If P(blue) = 1, P(green) = 4, and P(blue and green) = 12, which state
true?
The events are independent because P(blue). P(green) = P(blue and green).
The events are independent because P(blue). P(green) + P(blue and green).
The events are dependent because P(blue). P(green) = P(blue and green).
The events are dependent because P(blue). P(green) + P(blue and green).
Answer:
Not 100 percent sure but i think the correct answer is the last one.
Step-by-step explanation:
I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.
Again, not 100 percent sure, tried to give it my best shot.
Hope this helps.

Tyler simplified the expression x Superscript negative 3 Baseline y Superscript negative 9. His procedure is shown below.
x Superscript negative 3 Baseline y Superscript negative 9 = StartFraction 1 Over x cubed EndFraction times StartFraction 1 Over y Superscript negative 9 EndFraction = StartFraction 1 Over x cubed y Superscript negative 9 EndFraction
What is Tyler’s error?
Both powers should be in the numerator with positive exponents.
Both powers should be in the denominator with positive exponents.
The power x cubed should be in the numerator and the power y Superscript 9 in the denominator.
The power y Superscript 9 should be in the numerator and the power x cubed in the denominator.

Study the patterns and write down :
(a) Row 5
(b) Row n
(c) Row (n+1)
Answer:
a) Row 5: 75 - 216 - 51
b) 3n² - (n+1)³ - (71-4n)
c) 3(n+1)² - (n+2)³ - (67-4n)
Step-by-step explanation:
Column 3:
Arithmetic sequence with common difference: 63-67 = -4
an = 67 + (n-1)(-4)
an = 67 - 4n + 4
an = 71 - 4n
Row 5: 3×5² - (5+1)³ - (71-(5×4))
Row 5: 75 - 216 - 51
Row n: 3n² - (n+1)³ - (71-4n)
Row n+1: 3(n+1)² - (n+1+1)³ - 71-4(n+1)
Row n+1: 3(n+1)² - (n+2)³ - (67-4n)
Answer:
Column 1
Tn= 3n²
row n= 3n²
row n+1= 3(n+1)²
When n=5,
T₅ = 3(5)²
T₅ = 75
Thus, row 5= 75
Column 2
Tn= (n+1)³
row n= (n+1)³
row n+1
= (n+1+1)³
= (n+2)³
When n=5,
T₅ = (5+1)³
T₅ = 6³
T₅ = 216
row 5= 216
Column 3
Notice that the terms decrease by 4 with each row.
This means that there is a common difference of -4.
Common difference formula
Tn= a +d(n-1)
where a is the first term and d is the common difference.
Tn= 67 -4(n-1)
Now, simplify the formula
Tn= 67 -4n +4
Tn= 71 -4n
Row n= 71 -4n
Row n+1
= 71 -4(n+1)
= 71 -4n -4
= 67 -4n
when n=5,
T₅= 71 -4(5)
T₅= 51
Row 5= 51
Row n is the general formula for the pattern. To find the n+1 row, susbt. n+1 into n in the formula in row n.

Angle BCD is a circumscribed angle of circle A. Angle BAC measures 53°.
What is the measure of angle BCD?
37°
53°
74°
106°
The measure of angle BCD in circle A is 74°.
What is a circle?A circle is the locus of a point such that its distance from a fixed point is constant.
From the circle:
BC = CD (tangents that meet at the same point are equal)
But ∠ABC = 90° (angle between tangent and radius)
In triangle ABC:
∠ABC + ∠BCA + ∠BAC = 180 (triangle)
90 + ∠BCA + 53 = 180
∠BCA = 37°
Hence:
∠BCA = ∠ACD = 37°
angle BCD = ∠BCA + ∠ACD = 37 + 37 = 74°
The measure of angle BCD in circle A is 74°.

kelly is hanging shelves in her closet. She can buy sheleves for $1.25 a foot. Kelly buys one 5-foot shelf and a shelf that measure 24 inches. The rest of her materials cost $90. How much change will she get it she pay with $100? please explain and show your work
The 24 inch shelve is 2 feet ( 1 foot = 12 inches)
She bout 7 feet of shelves (5 + 2 = 7)
The total cost for the shelves was 7 x 1.25 = $8.75
She spend an additional 90 so her total spent was 90 + 8.75 = $98.75
Now subtract her total from 100 to find the amount of change:
100 - 98.75 = 1.25
The change was $1.25
Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation 2x2 + 4x + 8 = 0.

Answer:
No real number solutions.
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
The discriminant is b² - 4ac
• If b² - 4ac > 0 the equation has 2 real and distinct roots
• If b² - 4ac = 0 the equation has 2 real and equal roots
• If b² - 4ac < 0 the equation has no real roots
Given
2x² + 4x + 8 = 0 ← in standard form
with a = 2, b = 4 and c = 8, then
b² - 4ac = 4² - (4 × 2 × 8) = 16 - 64 = - 48 , thus
The equation has no real number solutions because the discriminant is < 0

Answer:y=-3
Step-by-step explanation:5(y+2/5)=-13
so first you simplify both sides of the equation
(5)(y)+(5)(2/5)=-13
then you distribute
5y+2=-13
then you subtract 2 from both sides
5y+2-2=-13-2
5y=-15
then u divide both side by 5
5y=-15

is 0.02 greater than 0.1
Answer:
No.
Step-by-step explanation:
Since there is a 1 in the tenths place for 0.1, and nothing in the tenths place for 0.02, 0.1 is greater.
The decimal number 0.1 is greater than 0.02. Therefore, the given statement is false.
The given decimal numbers are 0.02 and 0.1.
Similar to comparing other whole numbers, while comparing decimals, one should start with the digits with the highest place value. We first create a place value table with the supplied decimal numbers before starting the comparison. If the digits on the biggest place value match, we go to the digits in the next place to the right. We keep comparing digits until we reach the ones that are different.
Here, 0.1 is greater than 0.02.
Therefore, the given statement is false.

Answer: The volume is 3560.76 in^3 or 1134π
Step-by-step explanation:
The formula for the volume of a cylinder is πr^2*h
so the radius is 9 and the height is 14 so we will put that into the formula and solve.
v=3.14 * 9^2 * 14
v= 3.14 * 81 *14
v = 3560.76 in^3 or 1134π
