Ethics in sport requires four key virtues? Mention them.

Answer: B, E

Step-by-step explanation:

The possible 4-digit numbers are 1,680.

Probability that 4-digit number ends up being an odd number greater than or equal to 6000 is 57.14%.

a) The number of possible 4-digit numbers that can be formed using the given digits without repetition is given by the permutation formula:

P(8,4) = 8! / (8 - 4)! = 8 x 7 x 6 x 5 = 1,680

Therefore, there are 1,680 possible 4-digit numbers using the given digits.

b) The total number of 4-digit numbers that can be formed from the given digits is 1,680, as calculated in part a).

To find the probability that the 4-digit number is odd and greater than or equal to 6000, we need to calculate the number of odd 4-digit numbers in the range [6000, 6999] and the number of odd 4-digit numbers greater than or equal to 7000, and divide each by the total number of 4-digit numbers.

Number of odd 4-digit numbers in [6000, 6999]:

The last digit must be 1, 3, 5, or 7 (4 choices). The first three digits can be any of the remaining 7 digits (7 choices for the first digit, 6 choices for the second digit, and 5 choices for the third digit). Therefore, the number of odd 4-digit numbers in [6000, 6999] is:

4 x 7 x 6 x 5 = 840

Number of odd 4-digit numbers greater than or equal to 7000:

The first digit must be 7 (1 choice). The last digit must be 1, 3, 5, or 7 (4 choices). The second and third digits can be any of the remaining 6 digits (6 choices for the second digit and 5 choices for the third digit). Therefore, the number of odd 4-digit numbers greater than or equal to 7000 is:

1 x 4 x 6 x 5 = 120

The total number of odd 4-digit numbers is 840 + 120 = 960.

Therefore, the probability that the 4-digit number is odd and greater than or equal to 6000 is: 960 / 1,680 = 0.5714 or approximately 57.14%.

Answer:

Step-by-step explanation:

Given the system of equations -4x - 5y = 5  and -0.08x + 0.10y = 0.10, to know the number of solutions the system of equation has, we need to solve for the values of x and y if possible.

-4x - 5y = 5... 1

-0.08x + 0.10y = 0.10... 2

Multiplying equation 2 by 100 will give -8x+10y = 10

The resulting system of equation will be;

-4x - 5y = 5 ...3 * 8

-8x + 10y = 10... 4 * 4

Using the elimination method to solve the equation, multiplying eqn 3 by 8 and eqn 4 by 4 we have;

-32x-40y = 40

-32x+40y = 40

Subtracting both resulting equations to eliminate x will give;

-40y-40y = 0

-80y = 0

y = 0

Substituting y = 0 into equation 3 to get x we have;

-4x-5(0) = 5

-4x = 5

x = -5/4

The solution to the system of equations is (0, -5/4). This shows that the system of equations only has one solution

Step-by-step explanation:

The quotient q(x) is x^2 - 8x + 6, and the remainder r(x) is -x^3 + 8x^2 - 186x + 580, when dividing p(x) = x^3 + 2x^2 - 16x + 640 by d(x) = x + 10 using long division.

To find the quotient q(x) and the remainder r(x) when dividing p(x) by d(x) using long division, we can perform the following steps:

Step 1: Write the dividend (p(x)) and the divisor (d(x)) in descending order of powers of x:

p(x) = x^3 + 2x^2 - 16x + 640

d(x) = x + 10

Step 2: Divide the highest degree term of the dividend by the highest degree term of the divisor to determine the first term of the quotient:

q(x) = x^3 / x = x^2

Step 3: Multiply the divisor by the term obtained in step 2 and subtract it from the dividend:

p(x) - (x^2 * (x + 10)) = x^3 + 2x^2 - 16x + 640 - (x^3 + 10x^2) = -8x^2 - 16x + 640

Step 4: Repeat steps 2 and 3 with the new dividend obtained in step 3:

q(x) = x^2 - 8x

p(x) - (x^2 - 8x) * (x + 10) = -8x^2 - 16x + 640 - (x^3 - 8x^2 + 10x^2 - 80x) = 6x^2 - 96x + 640

Step 5: Repeat steps 2 and 3 with the new dividend obtained in step 4:

q(x) = x^2 - 8x + 6

p(x) - (x^2 - 8x + 6) * (x + 10) = 6x^2 - 96x + 640 - (x^3 - 8x^2 + 6x^2 - 80x + 60) = -x^3 + 8x^2 - 186x + 580

Since the degree of the new dividend (-x^3 + 8x^2 - 186x + 580) is less than the degree of the divisor (x + 10), this is the remainder, r(x).

The quotient q(x) is x^2 - 8x + 6, and the remainder r(x) is -x^3 + 8x^2 - 186x + 580, when dividing p(x) = x^3 + 2x^2 - 16x + 640 by d(x) = x + 10 using long division.

Answer:

∠ A ≈ 35.54°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = \(\frac{opposite}{adjacent}\) = \(\frac{BC}{AC}\) = \(\frac{5}{7}\), thus

A = \(tan^{-1}\) (\(\frac{5}{7}\) ) ≈ 35.54° ( to the nearest hundredth )

Answer:

(- 1, 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = 1 → (1)

3x - y = - 6 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

5x = - 5 ( divide both sides by 5 )

x = - 1

Substitute x = - 1 into either of the 2 equations and evaluate for y

Substituting into (1)

2(- 1) + y = 1

- 2 + y = 1 ( add 2 to both sides )

y = 3

Solution is (- 1, 3 )

If Olive Construction Company won the job, there is a 0.4615 (or 46.15%) probability that Base Construction Company would not have submitted a proposal.

Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.

The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.

So, the probability that the base construction company did not bid:

\(\begin{aligned}& P(A \mid B)=\frac{P(B \mid A) P(A)}{P(B \mid A) P(A)+P\left(B \mid A^{\prime}\right) P\left(A^{\prime}\right)} \\& P\left(B^{\prime} \mid O\right)=\frac{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)}{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)+P(O \mid B) P(B)} \\& P\left(B^{\prime} \mid O\right)=\frac{(0.5)(0.3)}{(0.5)(0.3)+(0.25)(0.7)} \\& P\left(B^{\prime} \mid O\right)=\frac{0.15}{0.15+0.175} \\& P\left(B^{\prime} \mid O\right)=0.4615\end{aligned}\)

You want a system of equations, their solution, and the interpretation of the solution for the scenario that Apple will be buying 12 ounces total of rice (x) at $1.73 per ounce and veggies (y) at $3.38 per ounce.

The given relations can be expressed in two equations:

The solution to these equations is shown in the attached graph. It is ...

  (x, y) ≈ (7.61, 4.39)

For Apple to buy 12 ounces of ingredients at a total cost of $28, Apple needs to buy 7.61 ounces of rice and 4.39 ounces of veggies.

Additional comment

If you understand the definitions of the variables, the interpretation is pretty straightforward:

  x = ounces of rice to purchase: x = 7.61 means Apple needs to purchase 7.61 ounces of rice.

  y = ounces of veggies to purchase: y = 4.39 means Apple needs to purchase 4.39 ounces of veggies.
