The probability that the sum of the ticket is 5, expressed as a percentage is 30%

The probability that an event will occur can be found by the ratio of the number of times the event occurs to the number of all possible events.

The five tickets in the box = 1, 2, 3, 4, 3

The tickets that sum to 5 are; 1 and 4, 2 and 3

The probability that the first ticket picked is 1 = 1/5

The probability that the next ticket picked is a 4 = 1/(5-1) = 1/4

Therefore, the probability of picking a 1 and 4 = (1/5) × (1/4) = 1/20

Similarly, the probability of picking a 4 and then a 1 is 1/20

The probability of picking tickets with numbers 1 and 4 in either order therefore = 2 × 1/20 = 1/10

The probability that the first ticket drawn is 2 = 1/5

The probability that the next ticket picked is a 3 = 2/(5-1) = 1/2

Therefore, the probability to draw a 2 and 3 = (1/5) × (1/2) = 1/10

The probability that the first ticket picked is 3 = 2/5

The probability that the next ticket picked is a 2 = 1/(5-1) = 1/4

Therefore, the probability of picking a 3 and 2 = (2/5) × (1/4) = 2/20 = 1/10

The probability of picking a 2 and a 3 in either order is therefore;

1/10 + 1/10 = 2/10 = 1/5

The probability that the sum of the ticket is 5, is the sum of the probabilities of picking a 1 and a 4 and the probability of picking a 2 and a 3, which is; 1/10 + 1/5 = 3/10 = 0.3

3rd choice  (x + 8)² + (y - 11)² = 4

Step-by-step explanation:

(x - -8)² + (y - 11)² = 2²

(x + 8)² + (y - 11)² = 4

Step-by-step explanation:

(x - h)² + (y - k)² = r²

h = -8

k = 11

r = 2

(x + 8)² + (y - 11)² = 2²

(x + 8)² + (y - 11)² = 4

The answer is C. (x+8)² + (y-11)² = 4

The common factor is  6[tex]e^{6x}[/tex]  (2x - 5)⁸.

What is a common factor?

These are the "common factors" when we determine the factors of two or more numbers and discover some of those factors are the same (or "common").

Given that

d/dx[[tex]e^{6x}[/tex](2x - 5)⁹]

The formula of the product rule is d/dx(uv) = uv' + vu'.

=(2x - 5)⁹d/dx([tex]e^{6x}[/tex]) +  [tex]e^{6x}[/tex]d/dx(2x - 5)⁹

Now applying the formula d/dx(x^n) = nx^(n-1), d/dx e^(mx) = m e^(mx)

=(2x - 5)⁹ 6[tex]e^{6x}[/tex] + [tex]e^{6x}[/tex]×2×9 × (2x - 5)⁸

= 6[tex]e^{6x}[/tex]  (2x - 5)⁹ + 18[tex]e^{6x}[/tex](2x - 5)⁸

Now taking common 6[tex]e^{6x}[/tex]  (2x - 5)⁸

The value of angle ABE is 52°

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted by triangle ABC.

The interior angles of a triangle are the inside angles formed where two sides of the triangle meet.

The sum of interior angle in a triangle is 180°

Angle EBD = 180-(90+27)

= 180-117

= 63°

angle ABE + EBD = ABD

ABE = ABD - EBD

ABE = 115-63

Answer:

Step-by-step explanation:

Solving For #7

We will use the Angle Bisector Theorem

The angle bisector theorem states that in a triangle, the angle bisector of any angle will divide the opposite side in the ratio of the sides containing the angle.

In the figure provided in #7 we see that QS bisects ∠Q forming two smaller triangles ΔPQS and ΔQRS

According to the angle bisector theorem:

[tex]\dfrac{PQ}{QR} = \dfrac{PS}{RS}\\\\\textrm{Or, alternatively}\\\\\dfrac{QR}{PQ} = \dfrac{RS}{PS}\\[/tex]

Given
[tex]QR = 12.6\\PQ = 7\\RS = x\\PS = 5\\\\[/tex]

[tex]\dfrac{PQ}{QR} = \dfrac{PS}{RS}\\\\\textrm{Or, alternatively}\\\\\dfrac{QR}{PQ} = \dfrac{RS}{PS}\\\\\\\rightarrow \dfrac{12.6}{7} = \dfrac{x}{5}[/tex]

If we multiply by [tex]5[/tex] both sides of the equation we can get rid of the denominator 5 on the right side:

Answer: A) $725

Step-by-step explanation:

The value of the asset that the business bought with $300 cash and $425 on credit is $725. The total amount that the business spent on the equipment is equal to the sum of the cash and the credit, which is $300 + $425 = $725.

Answer:

To find the amount of the discount, we need to multiply the purchase price by 20% or 0.20.

Discount = $365 × 0.20 = $73

So, the discount on a $365 purchase is $73.

The price after the discount would be $365 - $73 = $292.

To calculate the discount on a $365 purchase with a 20% discount, you can follow these steps:

1. Calculate the discount amount:

Discount = 20% x $365 = $73

2. Subtract the discount from the original price:

Final price = $365 - $73 = $292

Therefore, the final price of the $365 purchase with a 20% discount is $292.

Answer:

s = 13.6

m∠T = 35.7°

m∠U = 61.3°

Step-by-step explanation:

• Solving for side s:

To find the length of side s, we have to use the cosine rule:

[tex]\boxed{a^2 = b^2 + c^2 - 2bc \ cosA}[/tex],

where:

In this case, the unknown side is s, and the sides adjacent to it have lengths of 8 and 2. The angle opposite to s is ∠S = 83°. Therefore,

[tex]s^2 = 8^2 + 12^2 -2(8)(12) \cdot cos(83^{\circ})[/tex]

⇒ [tex]s = \sqrt{8^2 + 12^2 -2(8)(12)\cdot cos(83^{\circ})}[/tex]

⇒ [tex]s = \bf 13.6[/tex]

• Solving for m∠T:

In order to find m∠T, we can use the sine rule:

[tex]\boxed{\frac{sinA}{a}= \frac{sinB}{b} =\frac{sinC}{c}}[/tex],

which means that the ratios of the sines of angles and their opposite sides are equal for a triangle.

The side opposite to ∠T is US = 8. Therefore:

[tex]{\frac{sinT}{8} = \frac{sin(83^{\circ})}{13.6}}[/tex]

⇒ [tex]sinT= \frac{sin(83^{\circ})}{13.6} \times 8[/tex]

⇒ [tex]T = sin^{-1}( \frac{sin(83^{\circ})}{13.6} \times 8)[/tex]

⇒ [tex]T = \bf 35.7^{\circ}[/tex]

• Solving for m∠U:

Now that we know the values of two angles of the triangle, we can calculate the third angle using the fact that the angles in a triangle add up to 180°:

∠U + ∠S ∠T = 180°

⇒ ∠U + 83° + 35.7° = 180°

⇒ ∠U = 180° - 83° - 35.7°

⇒ ∠U = 61.3°

Answer:

(a) highest number of groups  = 5

(b) out how many, of each color marble, will be in each group.
5 red

3 blue

2 yellow

Step-by-step explanation:

The GCF of 25, 15, 10 gives you the greatest number of groups you can form with those numbers

GCF of 25, 15 and 10 can be found as follows by finding factors of each number:

25 = 5 x5

15 = 5 x 3

10 = 5 x 2

Choose the highest number that is common in each group and this is 5

So John can make a maximum number of 5 groups

Divide each number by the GCF to find how may in each group

25/ 5 = 5 red marbles
15/5 = 3 blue marbles

10/5 = 2 yellow marbles

So there are 5 groups max possible each group containing 5 red, 3 blue and 2 yellow marbles

Answer:

Step-by-step explanation:

To prove that sin(51) + sin(81) - cos(21) = 0, we can use the trigonometric identity:

sin(A + B) = sin(A)cos(B) + cos(A)sin(B)

We can rewrite 51 and 81 as the sum of two angles:

51 = 45 + 6

81 = 90 - 9

Using the above identity, we can write:

sin(51) = sin(45 + 6) = sin(45)cos(6) + cos(45)sin(6) = (2/2)sin(6) + (2/2)cos(6) = sin(6) + cos(6)

and

sin(81) = sin(90 - 9) = sin(90)cos(9) - cos(90)sin(9) = 0 + (-1)sin(9) = -sin(9)

Finally,

sin(51) + sin(81) - cos(21) = sin(6) + cos(6) - sin(9) - cos(21) = (sin(6) + cos(6)) - (sin(9) + cos(21))

We know that sin(90 - x) = cos(x) and cos(90 - x) = sin(x), so we can rewrite the right-hand side as:

(sin(6) + cos(6)) - (cos(90 - 9) + sin(90 - 21)) = (sin(6) + cos(6)) - (cos(9) + sin(69))

We also know that sin(180 - x) = -sin(x) and cos(180 - x) = -cos(x), so we can rewrite the right-hand side as:

(sin(6) + cos(6)) - (cos(9) + -sin(111)) = (sin(6) + cos(6)) - (-sin(111) + cos(9))

Since sin(6) + cos(6) = sin(6 + 90) = sin(96) and -sin(111) + cos(9) = sin(69 - 180) = -sin(111), we can simplify the expression further to:

sin(6) + cos(6) - (-sin(111)) + cos(9) = sin(96) + cos(9)

Since sin(x + y) = sin(x)cos(y) + cos(x)sin(y), we can write:

sin(96) + cos(9) = sin(60)cos(36) + cos(60)sin(36) = (2/2)sin(36) + (√3/2)cos(36) = sin(36) + (√3/2)cos(36)

Finally, since sin(2x) = 2sin(x)cos(x), we can write:

sin(36) + (√3/2)cos(36) = 2sin(18)cos(18) + (√3/2)cos(36) = 2(√2/2)(√2/2) + (√3/2)(√2/2) = (√2 + √6)/2 + (√6/2) = (√2 + √6)

So, sin(51) + sin(81) - cos(21) = (√2 + √6) ≠ 0.

Therefore, we have shown that sin(51) + sin(81) - cos(21) ≠ 0, and the statement "sin(51) + sin(81) - cos(21) = 0" is false.
