The probability of selecting a divisor of 6 is 66.7%.

It is expressed as a number between 0 and 1, where 0 represents an impossible event (it will never occur) and 1 represents a certain event (it will always occur).

1, 2, 3, and 6 can be divided by 6.

To find the probability (p) of selecting a divisor of 6, we need to divide the number of divisors of 6 by the total number of possible outcomes, which is also 6 (since there are 6 positive integers from 1 to 6).

So, p(divisor of 6) = number of divisors of 6 / total number of outcomes

= 4 / 6

= 2 / 3

We can multiply this fraction by 100 to get the percentage:

p(divisor of 6) = 2 / 3 * 100

= 66.7%

Rounded to the nearest tenth, the answer is 66.7%. Therefore, the probability of selecting a divisor of 6 is 66.7%.

Answer:

  "time and a half" workers were paid 50% more per day

Step-by-step explanation:

You want to know the relative daily pay rates of laborers making time and a half versus those who were not. 4 getting time and a half and 20 not earned a total of $2080, while 2 getting time and a half and 15 not earned a total of $1440.

We can let x and y represent the daily pay of time and a half workers, and those not earning time and a half. The two payrolls can be described by ...

  4x +20y = 2080

  2x +15y = 1440

Subtracting the first equation from 2 times the second, we have ...

  2(2x +15y) -(4x +20y)  = 2(1440) -(2080)

  10y = 800 . . . . . . . simplify

  y = 80 . . . . . . . . . . divide by 10

  2x +15(80) = 1440

  2x = 240 . . . . . . . . . . subtract 1200

  x = 120 . . . . . . . . divide by 2

Workers getting time and a half made $120 per day; workers not getting time and a half made $80 per day. Workers getting time and a half made half again as much as those who didn't: $40 per day more, or 50% more, or half-again as much.

"Time and a half" means the pay is 50% more. That's what we see here. You don't need any math to say those getting time and a half were getting 50% more per day.

Anand's business charges $25 for a 10-mile ride, which is less than Moussa's overall expenses.

In comparison to Moussa, Anand's business costs less per mile.

Let's examine why by contrasting the costs charged by the two businesses for a 10-mile trip:

With a $3 pick-up fee and $2.20 per mile,

Moussa's business costs a total of $3 + $2.20*10 = $25.

Less than Moussa's overall expense,

Anand's business charges $25 for a 10-mile ride.

For all other distances mentioned in the table, we can verify that Anand's business charges less per mile than Moussa's. Thus, it is accurate that

"Anand's company charges less per mile than Moussa's."

The sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles.

To solve the triangle, we need to find the values of the remaining sides and angles. We can start by using the Law of Sines, which states that:

a / sin A = b / sin B = c / sin C

where a, b, and c are the sides of the triangle, and A, B, and C are the angles opposite to those sides.

Using the given values, we can write:

a / sin 51 = 7 / sin B

a / sin 51 = 10 / sin C

To solve for a, we can use either of the two equations above. Let's use the first one and solve for sin B:

sin B = (7 / sin 51) * sin B

sin B = 7 / (sin 51 / sin B)

sin B = 7 / sin(180 - 51 - B)

sin B = 7 / sin(129 - B)

Using the sine rule, we can determine the angle B:

sin B / 7 = sin(129 - B) / 10

sin B = (7/10) * sin(129 - B)

sin B = (7/10) * (sin 129 * cos B - cos 129 * sin B)

sin B = (7/10) * sin 129 * cos B - (7/10) * cos 129 * sin B

(7/10 + (7/10) * cos 129) * sin B = (7/10) * sin 129 * cos B

sin B = (7/10) * sin 129 * cos B / (7/10 + (7/10) * cos 129)

sin B = sin 51.5

B = sin(sin B)

B = sin(sin 51.5)

B ≈ 51.5°

We can now find the remaining angle, C:

C = 180 - A - B

C = 180 - 51 - 51.5

C ≈ 77.5°

Finally, we can use the Law of Sines again to find the remaining side, a:

a / sin A = c / sin C

a / sin 51 = 10 / sin 77.5

a = (10 * sin 51) / sin 77.5

a ≈ 8.3

Therefore, the sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

Answer:

Step-by-step explanation:

Given the figure with triangle ABC similar to triangle EDC and AB=8 mi, ED=2 mi, BD = 7.5 mi, you want the measures of CD and AE.

Similar triangles will have corresponding sides proportional. That means ...

  ED/CD = AB/CB

  2/CD = 8/(7.5 -CD)

Inverting the ratios and multiplying by 8 gives ...

  4·CD = 7.5 -CD

  5·CD = 7.5 . . . . . . . add CD

  CD = 1.5 . . . . . . . . . divide by 5

The distance AE is the hypotenuse of a right triangle with side lengths 7.5 and (8+2) = 10. The Pythagorean theorem can be used to find AE:

  AE² = 7.5² +10² = 56.25 +100 = 156.25

  AE = √156.25 = 12.5

AE = 12.5 miles, the distance to the mall.

Given:  [tex]\textsf{8(x - 3) = 2x + b + 6x}[/tex]

Find: [tex]\textsf{Which values for b are not a solution}[/tex]

Solution: In order to make it easier for us to determine the answer, let us first simplify the expression that was given to us.  We can do that by first combining like terms on the right side of the equation and distributing the 8 on the left side of the equation.

We can now subtract 8x from both sides of the equation.

Now that we know that b is equal to -24, that means that any value other than -24 would cause the equation to have no solutions.  Therefore, the correct answer would be B (-3), C (3), and D (24).

Answer:

-2x × 10^1 + 8 × 10^0

or

-2x × 10 + 8 × 1

Step-by-step explanation:

Multiply the following to put them in standard form

-4 (5x-2)=

-20x +8

standard form

-2x × 10^1 + 8 × 10^0

or

-2x × 10 + 8 × 1   (remember  PEMDAS)

Assuming you meant "x - 2(x - 2) * 3" as the expression, here is how you can simplify it:

= x - 2(3x - 6) // Distribute the 2

= x - 6x + 12 // Distribute the -2

= -5x + 12 // Simplify

Therefore, the simplified expression is -5x + 12.

To simplify the expression "x subtract 2 x subtract 2 multiply 3," we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, we need to simplify the multiplication by 3 inside the parentheses:

Next, we can simplify the subtraction of 2x:

-x - 2(3)

Finally, we can simplify the multiplication of 2 and 3:

-x - 6

Therefore, the simplified expression is "-x - 6".

The solution to the triangle is: a ≈ 22.4, b = 4 , c ≈ 77.2 ,A = 27° ,B ≈ 42.5°

C ≈ 110.5°  we got the answer by using law of sine

what is  law of sine?

The Law of Sines, also known as the Sine Rule, is a mathematical formula used in trigonometry to relate the sides and angles of a non-right-angled triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.

In the given question,

Using the law of sines and the fact that the angles of a triangle sum up to 180 degrees, we can solve for the missing parts of the triangle:

sin(A)/a = sin(B)/b = sin(C)/c

sin(27)/a = sin(B)/42 = sin(C)/72

We can use the first equation to solve for a:

a = b(sin(A)/sin(B)) = 42(sin(27)/sin(B)) ≈ 22.4161

Next, we can use the second equation to solve for sin(B):

sin(B) = b(sin(A)/a) = 42(sin(27)/a) ≈ 0.6822

Taking the inverse sine, we find that B ≈ 42.4827 degrees.

Now we can use the fact that the angles of a triangle sum up to 180 degrees to solve for C:

C = 180 - A - B ≈ 110.5173 degrees.

Finally, we can use the law of sines again to solve for the remaining side, c:

c = a(sin(C)/sin(A)) = 22.4161(sin(110.5173)/sin(27)) ≈ 77.2352

Therefore, the solution to the triangle is:

a ≈ 22.4

b = 42

c ≈ 77.2

A = 27°

B ≈ 42.5°

C ≈ 110.5°

Answer: No, you cannot always divide by e^x. When e^x equals zero, dividing by it would result in an undefined value or division by zero error.

For example, consider the function f(x) = e^x. We know that e^x is never equal to zero for any value of x. Therefore, we can always divide by e^x for any value of x, and the resulting quotient will be well-defined.

However, if we consider the function g(x) = 1 / e^x, we cannot always divide by e^x. When e^x equals zero, g(x) will be undefined. In fact, there is no value of x for which e^x is equal to zero, so the function g(x) is well-defined for all values of x.

In summary, dividing by e^x is allowed for most cases, except when e^x equals zero.

For the given cone, the approximate volume of the toy top is 106.81 cubic centimeters. The three dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.

Volume is a three-dimensional quantity that measures the amount of space occupied by an object or a region in space.

The volume of the toy top can be calculated by finding the volumes of the cone and cylinder and then adding them together.

The volume of the cone is given by the formula V = (1/3)π[tex]r^{2}[/tex]h, where r is the radius and h is the height of the cone. In this case, the slant height is given, so we need to use the Pythagorean theorem to find the height:

h = [tex]\sqrt{(l^2 - r^2)[/tex] = [tex]\sqrt{(10^2 - 6^2)[/tex] = √(64) = 8 cm

Therefore, the volume of the cone is:

V_cone = (1/3)π[tex]r^2[/tex]h = (1/3)π([tex]6^2[/tex])(8) ≈ 100.53 [tex]cm^3[/tex]

The volume of the cylinder is given by the formula V = π[tex]r^2[/tex]h, where r is the radius and h is the height of the cylinder. In this case, the diameter is given, so we need to divide by 2 to get the radius:

V_cone = (1/3)πh = (1/3)πr = d/2 = 1 cm = 2 cm

Therefore, the volume of the cylinder is:

V_cylinder = π[tex]r^{2}[/tex]h = π([tex]1^{2}[/tex])(2) ≈ 6.28

The total volume of the toy top is:

V = V_cone + V_cylinder ≈ 100.53 + 6.28  ≈  106.81 T

Therefore, the approximate volume of the toy top is 106.81 cubic centimeters.

Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.98693

If 58% = 58÷100 of the people have been vaccinated, then;

1 - (58/100) = 42% = 42÷100 of the people who have not been vaccinated.

Now:

Probability, P( > 1 ), that at least one of the selected four has been vaccinated is given by;

P( > 1 ) = 1 - P(0)                 -----------(1)

Where;

P(0) = probability that all of the four have not been vaccinated.

P(0) = P(1) x P(2) x P(3) x P(4)×p(5)

Where;

P(1) = Probability that the first out of the four has not been vaccinated

P(2) = Probability that the second out of the four has not been vaccinated

P(3) = Probability that the third out of the four has not been vaccinated

P(4) = Probability that the fourth out of the four has not been vaccinated

P(5)=Probability that the fifth out of the five has not been vaccinated

Remember that 42÷100 of the population has not been vaccinated. Therefore,

P(1) = 42÷100    

P(2) = 42÷100

P(3) = 42÷100

P(4) = 42÷100

P(5)=42÷100

P(0) = (42÷100) x (42÷100) x (42÷100) x (42÷100)×(42÷100)

P(0) = (42÷100)⁵

P(0) = (0.42)⁵

P(0) = 0.013067

Therefore, from equation (1);

P( > 1 ) = 1 -0.013067

The area of the shaded region is 1.916 ft²

Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.

To calculate the area of the shaded region, we need to find the area of the entire circle and subtract the area of the unshaded portion.

The central angle corresponding to the shaded region is 110 degrees. The entire circle has a central angle of 360 degrees.

The unshaded portion of the circle is the sector that corresponds to the central angle of 360 - 110 = 250 degrees. The area of a sector of a circle with radius r and central angle θ is given by the formula:

A = (θ/360)πr²

Substituting θ = 110 degrees and r = 2 ft, we get:

A = (110/360)π(2)

A =  (0.305)π(2)

A =  (0.305)π(2)

A = 0.61π

A = 1.916 ft²
