The probability of drawing a jack, given that we are told it is a face card, is 1/3 or approximately 0.33.There are 12 face cards in a well-shuffled euchre deck, comprising of 4 jacks, 4 queens, and 4 kings. The probability of drawing a face card from the deck is 12/32, or 3/8.

Now, we are asked to find the probability of drawing a jack, given that we already know the card is a face card. This can be calculated using conditional probability, which is the probability of an event occurring given that another event has already occurred.

The probability of drawing a jack given that the card is a face card can be represented as P(Jack | Face card). Using Bayes' theorem, we can calculate this probability as follows:

P(Jack | Face card) = P(Face card | Jack) * P(Jack) / P(Face card)

Here, P(Face card | Jack) represents the probability of drawing a face card given that the card is a jack, which is 1. P(Jack) represents the probability of drawing a jack from the deck, which is 4/32 or 1/8.

We already know that P(Face card) is 3/8.Substituting these values into the formula, we get:

P(Jack | Face card) = (1 * 1/8) / (3/8) = 1/3.

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

C. If a number has a negative cube root, then the number is negative.  

Step-by-step explanation:

took the quiz

The inverse of the conditional statement is " If a number does not have a negative cube root, then the number is not negative. "

A conditional statement is a type of logical statement that expresses a relationship between two propositions or statements. It typically takes the form "if p, then q" where p and q are propositions. The statement "if p, then q" is read as "if p is true, then q is true" or "p implies q".

The truth value of a conditional statement depends on the truth values of its antecedent (p) and its consequent (q). If p is true and q is true, then the conditional statement is true. If p is true and q is false, then the conditional statement is false. If p is false, then the truth value of the conditional statement is irrelevant and it is said to be vacuously true.

Given data ,

Let the statement be represented as A

Now , the inverse of the statement is A'

where A = "If a number is negative, then it has a negative cube root."

Now , the inverse of the conditional statement is

A' = " If a number does not have a negative cube root, then the number is not negative. "

Hence , the inverse is " If a number does not have a negative cube root, then the number is not negative. "

Option D is correct

Graph attached

What is the question for this so I can answer it?

False. If A is a subset of or equal to B, it does not necessarily mean that A intersection B equals A. The intersection of two sets A and B is defined as the set of elements that belong to both A and B.

If A is a subset of B, then every element of A also belongs to B. Therefore, the intersection of A and B must include all the elements of A. However, it may also include additional elements that belong to B but not to A.
For example, let A = {1, 2} and B = {1, 2, 3}. A is a subset of B since every element of A also belongs to B. However, the intersection of A and B is {1, 2}, which is not equal to A.
In summary, if A is a subset of or equal to B, it is possible for A intersection B to equal A, but it is not always true. The intersection can also include additional elements from B that do not belong to A.

The height of the school building is approximately 9.69 meters or 10.53 meters (rounded to the nearest hundredth).

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the studies of relationships between angles and sides of triangles.

Let's denote the height of the school building as "h".

From the given information, we can draw a right triangle with the mirror on the ground, the top of the school building, and Aria's eyes as the vertices. The distance from Aria to the mirror is 1.25 meters, and the distance from the mirror to the school building is the unknown height "h". The distance from Aria's eyes to the mirror is 1.15 meters.

We can use similar triangles to set up an equation to solve for "h".

In the smaller triangle formed by Aria's eyes, the mirror, and the point directly below the top of the school building, we can see that:

h/1.25 = (h + 1.15)/11.45

This equation comes from the fact that the ratios of corresponding sides in similar triangles are equal.

Simplifying this equation gives us:

1.45h = 14.06875

Dividing both sides by 1.45 gives us:

h ≈ 9.6931

Hence, The height of the school building is approximately 9.69 meters or 10.53 meters (rounded to the nearest hundredth).

The solution of the Chinese Remainder Theorem can be calculated by using the formula: \({\displaystyle x=\sum _{i=1}^{k}a_{i}M_{i}N_{i}.}\)

According to the Chinese remainder theorem, if one knows the remainders of the Euclidean division of an integer n by multiple numbers, one may uniquely calculate the remainder of the division of n by the product of these integers, provided that the divisors are pairwise coprime (no two divisors share a common factor other than 1).

For example, if we know that the remainder of n divided by 3 is 2, the remainder of n divided by 5 is 3, and the remainder of n divided by 7 is 2, we may calculate the remainder of n divided by 105 (the product of 3, 5, and 7) without knowing the value of n. This tells us that if n is a natural number less than 105, then the only possible value of n is 23.

Answer:

6x - 4

Step-by-step explanation:

For expanding (3x -2) 2 , (3x - 2) is to be multiplied with 2.

(3x - 2) × 2 = 6x - 4

The greatest common divisor (gcd) of 5544 and 910 is 182. Integers a = 49 and b = -300 can be used to express the gcd as 5544a + 910b = 182.



To find the gcd of 5544 and 910, we can use the Euclidean algorithm or prime factorization. Here, we will use the Euclidean algorithm.

Step 1: Divide 5544 by 910.
   5544 ÷ 910 = 6 remainder 414

Step 2: Divide 910 by 414.
   910 ÷ 414 = 2 remainder 82

Step 3: Divide 414 by 82.
   414 ÷ 82 = 5 remainder 4

Step 4: Divide 82 by 4.
   82 ÷ 4 = 20 remainder 2

Step 5: Divide 4 by 2.
   4 ÷ 2 = 2 remainder 0

Since the remainder is now 0, we have found the gcd. The last non-zero remainder, which is 2, is the gcd of 5544 and 910.

To express the gcd as 5544a + 910b = 182, we need to find integers a and b that satisfy the equation.

By reversing the steps of the Euclidean algorithm, we can find a and b.

Step 4: Working backward, we have 2 = 82 - 4 × 20.
Step 3: Substituting 82 - 4 × 20 for 2, we have 2 = 82 - 4 × (414 - 82 × 5).
Step 2: Simplifying, we have 2 = 82 - 4 × 414 + 20 × 82.
Step 1: Substituting 82 - 4 × 414 + 20 × 82 for 2, we have 2 = (910 - 2 × 414) - 4 × 414 + 20 × (5544 - 910 × 6).
       Simplifying further, we have 2 = 910 - 2 × 414 - 4 × 414 + 20 × 5544 - 20 × 910 × 6.
       Combining like terms, we get 2 = 5544 - 910 × 2 - 4 × 414 - 20 × 910 × 6.
       Rearranging, we have 2 = 5544 - 910 × 2 - 4 × 414 - 20 × 910 × 6.
       Simplifying, we have 2 = 5544 - 1820 - 1656 - 109200.
       Combining like terms, we get 2 = -109132.

Therefore, we have found that a = 49 and b = -300, which satisfy the equation 5544a + 910b = 182, where the gcd is 182.

Answer:

0.5563

Step-by-step explanation:

Given that :

Probability of winning (p) = 0.15

Number of months = number of trials (n) = 5

1 - p = 1 - 0.15 = 0.85

Probability of winning atleast one price ;

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x≥1) = p(1) + p(2) + p(3) + p(4) + p(5)

Using the binomial probability calculator to save computation time :

P(x≥1) = 0.556294

P(x≥1) = 0.5563

Probabilities are used to determine the chances of events.

The probability that you win at least one prize is 0.5563

The given parameters are:

\(p = 0.15\) --- the probability of winning

The probability of losing (q) is then calculated using the following complement rule

\(q= 1 - p\)

\(q= 1 - 0.15\)

\(q= 0.85\)

The probability that you win at least one prize is the complement of not winning at all.

So, we have:

\(P(At\ least\ 1) = 1 - P(None)\)

This gives

\(P(At\ least\ 1) = 1 - 0.85^5\)

\(P(At\ least\ 1) = 1 - 0.4437\)

Evaluate like terms

\(P(At\ least\ 1) = 0.5563\)

Hence, the probability of winning at least one prize is 0.5563
