Hello and Good day,
This question is relating to probability and it can come in percentages and fractions. I will follow directions as the problem states and provide both.
1. There is a 1/20 or 5% chance that the dart would land on section 20.
2. There is a 10/20 or 50% chance that the dart would land on an odd number.
There are 10 odd numbers present on the dart board.
3. 4/20 or 20%
There are 4 numbers greater than 16.
4. 0/20 or 0%
This is because there are no 25's on the dart board
5. 17/20 or 85%
This is because there are 17 numbers that aren't 4, 5, or 6.
6. 7/20 or 35%
There are 7 numbers less than 8.

7x+2y=47
5x-4y=1
use elimination method
Answers
Answer:
x=5, y=6
Step-by-step explanation:
7x+2y=47
5x-4y=1
to use elimination method , you want to add the two equations together so that either x or y cancels out. For these equations, we will multiply the first equation by 2. (This will cancel out y value)
2(7x+2y)=2(47)
14x+4y =94
————————
add above equation to second equation:
14x+4y=94 above equation
5x-4y=1 second equation
19x=95 added together
x=5
—————————————
‘solve for y by substituting x value (5) into either original equation
5x-4y=1
5(5)-4y=1
25-4y=1
-4y=-24
y=6

True False
1) It is unlikely that a blue marble will be selected.
2) It is certain that a green marble will be selected.
3) It is impossible that a yellow marble will be selected.
4) It is unlikely that a red marble will be selected.
Answers
Explain: it could not be certain unless there was 16 green and it is likely that red would be picked as it is the most common
Answer:
1 is FALSE
2 is TRUE
3 is FALSE
4 is FALSE
Step-by-step explanation:
1 is false because the blue marble is 2 only
2 is true because green marble has a 100% you get this.
3 is false because we din't have yellow marble
4 is false because red is has 10 marble so you get this red marbke is has 82% because red marble is 2nd most at the number of color

Yes. Only squares have four angles that are the same measure.
Yes. It could be a square if all sides are also the same measure.
No. If the sides are not the same length, it is not a square.
No. The figure is a rhombus.

Answer:
Yes
Step-by-step explanation:
Yes. It could be a square if all sides are also the same measure.
A parallelogram will be a square when all four sides are of equal in length and all four angles are same.
A parallelogram is a quadrilateral with opposite sides parallel . A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.A square is a parallelogram when all four sides of parallelogram are same and all four angles are equal to 90 degree.Learn more:

Shelby made a mistake in her checkbook. She wrote a check for $8.50 to rent a video game but mistakenly recorded it in her checkbook as an $8.50 deposit. Part A: Which point represents each of Shelby's transaction on the number line below? Explain the difference between these two transactions. Part B: Use absolute value to explain how a debt of $8.50 and a deposit of $8.50 are similar.
Answers
Answer:
Part A
The first transaction which is to write a check of $8.50 is a debit transaction which carries a negative sign while
The second transaction which states that she wrote it as a deposit carries a positive sign because deposit means to add
Part B
The absolute value of a number is never negative.
|-8.50| = 8.50
Step-by-step explanation:
Part A: Which point represents each of Shelby's transaction on the number line below? Explain the difference between these two transactions.
The firsts transaction says:
She wrote a check for $8.50 to rent a video game.
Writing a check of $8.50 is a debit to her bank account. This is a negative value because $8.50 is taken from the money in her bank account.
Mathematically this means, -$8.50
The second transaction states that:
She mistakenly recorded it in her checkbook as an $8.50 deposit.
Mathematically, a deposit means a positive action, where money is added to the money in her bank account.
Hence,
+$8.50
Part B: Use absolute value to explain how a debt of $8.50 and a deposit of $8.50 are similar.
In mathematics it is important to note that:
The absolute value of a number is never negative.
Hence,
Debt of $8.50 = -8.50
Deposit of $8.50 = +8.50
Hence,
|-8.50| = 8.50
(6, - 3, 1) and (8,9,-11) find the angle between the vector

The angle between the two vectors is 84.813°.
Step-by-step explanation:
Statement is incomplete. Complete form is presented below:
Let be (6,-3, 1) and (8, 9, -11) vector with same origin. Find the angle between the two vectors.
Let [tex]\vec u = \langle 6, -3, 1 \rangle[/tex] and [tex]\vec v = \langle 8,9,-11 \rangle[/tex], the angle between the two vectors is determined from definition of dot product:
[tex]\theta = \cos^{-1} \left(\frac{\vec u \,\bullet \,\vec v}{\|\vec u\|\cdot \|\vec v\|} \right)[/tex] (1)
Where:
[tex]\vec u[/tex], [tex]\vec v[/tex] - Vectors.
[tex]\|\vec u\|[/tex], [tex]\|\vec v\|[/tex] - Norms of each vector.
Note: The norm of a vector in rectangular form can be determined by either the Pythagorean Theorem or definition of Dot Product.
If we know that [tex]\vec u = \langle 6,-3,1 \rangle[/tex] and [tex]\vec v = \langle 8, 9,-11 \rangle[/tex], then the angle between the two vectors is:
[tex]\theta = \cos^{-1}\left[\frac{(6)\cdot (8) + (-3)\cdot (9) + (1)\cdot (-11)}{\sqrt{6^{2}+(-3)^{2}+1^{2}}\cdot \sqrt{8^{2}+9^{2}+(-11)^{2}}} \right][/tex]
[tex]\theta \approx 84.813^{\circ}[/tex]
The angle between the two vectors is 84.813°.

Use the quadratic formula to solve for x.
6x²-3x=1
Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
Answers
If we know the quadratic formula, the quadratic formula is
x = [-b ± √(b²- 4ac)] / 2a
Gosh! So overwhelming! But let's look at the composition of a quadratic equation:
ax² + bx + c = 0
And we have 6x² - 3x = 1. So, what do we do? We need to put this quadratic equation into an easy form to find the value of a, b, and c to plug in to the equation.
We can just minus one on both sides to get this:
6x² - 3x - 1 = 0
Is it in the form of ax² + bx + c? Yes! a = 6, b = -3, and c = -1. Now, all we have to do is plug it into the quadratic formula.
x = [-b ± √(b²- 4ac)] / 2a
x = [-(-3) ± √((-3)²- 4(6)(-1))] / 2(6)
[3 ± √(9- 4(6)(-1))] / 12
[3 ± √(9 + 24)] / 12
[3 ± √(33)] / 12
At this point, we should just use a calculator, and recognize we have two answers because of the plus-or-minus sign! (or this sign: ±)
[3 ± √(33)] / 12
1) [3 + √(33)] / 12 = 0.73 approximately
2) [3 - √(33)] / 12 = -0.23 approximately
So, x=0.73 and x= -0.23.
Si el recíproco del m% de p se divide por el recíproco del m% de q resulta: A) pq/100 B)pq C)1/pq D)p/q E)q/p
Answers
Answer:
E) q / p
Step-by-step explanation:
Spanish
m% de p = pf / 100
m% de q = mq / 100
El recíproco se obtiene haciendo que el numerador sea el denominador y el denominador el numerador.
El recíproco de m% de p = 100 / mp
El recíproco de m% de q = 100 / mq
Divisor
100 / mp / 100 / mq
= 100 / mp * mq / 100
= mq / mp
= q / p
English
If the reciprocal of m% of p is divided by the reciprocal of m% of q, the result is: A) pq / 100 B) pq C) 1 / pq D) p / q E) q / p
m% of p= mp/100
m% of q= mq/100
The reciprocal is obtained by making the numerator the denominator and the denominator the numerator
The reciprocal of m% of p= 100/mp
The reciprocal of m% of q= 100/mq
Dividing
100/mp/ 100/mq
=100/mp* mq/100
= mq/mp
= q/p

WILL REWARD BRAINIEST! What is the volume of the composite figure if both the height and the diameter of the cylinder are 10.5 feet? Give the exact answer and approximate to two decimal places.
Answers
Answer:
908.74
Step-by-step explanation:
The formula for the volume of a cylinder is V = h * pi * r^2
h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.
So now plug it into the formula:
V = 10.5 * pi * (5.25)^2
= 908.74
Hope this helped! :)
Answer:
1211.65 cubed ft.
Step-by-step explanation:
Half sphere: V = 4/3(3.24)(5.25^3)
V = 605.82
Divide by two since we need to find the volume of the half sphere, not the full sphere.
605.82 ÷ 2 = 302.91
Cylinder: V = (3.14)(5.25^2)(10.5)
V = 908.74
Add the two volumes to each other to find the total volume of the composite figure.
908.74 + 302.91 = 1211.65

3/5 pencils sold in the morning. 1/4 of the remainder in the afternoon. If 200 more pencils were sold in the morning than afternoon, how many pencils did they start with
Answers
Answer:
x = total pencils = 400 pencils
Step-by-step explanation:
Let
x = total pencils
Pencils sold in the morning = 3/5x
Remaining pencil = x - 3/5x
= 5x-3x/5
= 2/5x
Pencils sold in the afternoon = 1/4 of the remainder
= 1/4 * 2/5x
= 2/20x
= 1/10x
Pencils sold in the afternoon = 1/10x
3/5x + 200 = 1/10x
3/5x - 1/10x = 200
(6x-x)/10 = 200
5/10x = 200
1/2x = 200
x = 200 ÷ 1/2
= 200 × 2/1
x = 400 pencils
x = total pencils = 400 pencils
