Is the number of fish caught during a fishing tournamentnumber of fish caught during a fishing tournament discrete or continuous?

Answers

Final answer:

The number of fish caught in a fishing tournament is a discrete variable, as it can only take specific or separate values which are whole numbers, not fractions or decimals.

Explanation:

The number of fish caught during a fishing tournament would be considered a discrete variable in mathematics. This is because discrete variables are variables that can only take specific or separate values.

In this case, you can't catch half a fish or 2.3 fish in a tournament, you can only catch whole fish. This makes the number of fish caught a discrete variable because the count can only be in whole numbers. This is different from a continuous variable, such as the amount of time spent fishing or the weight of the fish caught, which could take on any value within a given range.

Bruce had an EKG to measure his heartbeat rate. After conversion, the function produced could be modeled by a cosine function, and the wave produced a maximum of 4, minimum of −2, and period of pi over 2. Which of the following functions could represent Bruce's EKG read-out?
f(x) = 4 cos pi over 2x − 2
f(x) = 3 cos 4x + 1
f(x) = 3 cos pi over 2x + 1
f(x) = 4 cos 4x − 2

Answers

y= a.cos (bx) + midline

a = Amplitude = |4+2}/2 = |3|

Period = 2π/b = (2π) / (π/2) = 4

midline = (4-2)/2 = 1

Then the equation is:

y=3.cos(4x) + 1

Answer:

Option B.

Step-by-step explanation:

Bruce had an EKG to measure his heartbeat rate. After conversion, the function produced was modeled by a cosine function.

Now we will form this function.

Function will be in the form of f(x) = a cos(Bx) + d

Amplitude [tex]a=\frac{Maximum-minimum}{2}[/tex]

[tex]a=\frac{4+2}{2}=3[/tex]

Period = π/2

And [tex]Period=\frac{2\pi }{B}[/tex]

⇒[tex]\frac{\pi }{2}=\frac{2\pi }{B}[/tex]

⇒ B = 4

Since minimum is (-2) and maximum is (4), means cosine graph was shifted upwards.

Mid line of the graph is [tex]x=\frac{4+2}{2}=3[/tex] which shows graph is shifted by one unit above the x-axis.

Now the function we get is f(x) = 3 cos4x + 1

Therefore option B is the answer.

The steps below show the incomplete solution to find the value of p for the equation 4p − 2p + 4 = −1 + 21:

Step 1: 4p − 2p + 4 = −1 + 21
Step 2: 4p − 2p + 4 = 20
Step 3: 2p + 4 = 20

Which of these is most likely the next step?
2p = 5
2p = 8
2p = 16
2p = 24

Answers

Step 1: 4p − 2p + 4 = −1 + 21
First they combined like terms on one side.

Step 2: 4p − 2p + 4 = 20
Then they combined like terms on the other side.

Step 3: 2p + 4 = 20
Now you have to subtract 4 from both sides.

Step 4: 2p = 16

So the answer is C. 2p = 16

It's 2p = 16. You subtract 4 from both sides.
2p+4=20
-4=-4
2p = 16

Which choices are real numbers? Check all that apply.
A. (-131072)^1/7
B. (-531441)^1/12
C. (-1024)^1/5
D. (-256)^1/8

Answers

Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.

[tex] \sqrt{x} [/tex]

That can be written as

x^(1/2)

...and when you take an even root of a negative number, there is no real answer. (2 is an even number).

Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.

So, A and C are the answer choices to select.

The real numbers are:

A. [tex]\((-131072)^{1/7}\)[/tex]

C. [tex]\((-1024)^{1/5}\)[/tex]

These have odd roots, resulting in real numbers.

To determine which of the given expressions are real numbers, we need to check if the roots of negative numbers are defined within the set of real numbers.

A. [tex]\((-131072)^{1/7}\)[/tex]

The expression [tex]\((-131072)^{1/7}\)[/tex] is the 7th root of [tex]\(-131072\)[/tex]. Since 7 is an odd number, the 7th root of a negative number is defined and is a real number.

So, [tex]\((-131072)^{1/7}\)[/tex] is a real number.

B. [tex]\((-531441)^{1/12}\)[/tex]

The expression [tex]\((-531441)^{1/12}\)[/tex] is the 12th root of [tex]\(-531441\)[/tex]. Since 12 is an even number, the 12th root of a negative number is not defined within the set of real numbers.

So, [tex]\((-531441)^{1/12}\)[/tex] is not a real number.

C. [tex]\((-1024)^{1/5}\)[/tex]

The expression [tex]\((-1024)^{1/5}\)[/tex] is the 5th root of [tex]\(-1024\)[/tex]. Since 5 is an odd number, the 5th root of a negative number is defined and is a real number.

So, [tex]\((-1024)^{1/5}\)[/tex] is a real number.

D. [tex]\((-256)^{1/8}\)[/tex]

The expression [tex]\((-256)^{1/8}\)[/tex] is the 8th root of [tex]\(-256\)[/tex]. Since 8 is an even number, the 8th root of a negative number is not defined within the set of real numbers.

So, [tex]\((-256)^{1/8}\)[/tex] is not a real number.

Summary:

- A. [tex]\((-131072)^{1/7}\)[/tex] is a real number.

- B. [tex]\((-531441)^{1/12}\)[/tex] is not a real number.

- C. [tex]\((-1024)^{1/5}\)[/tex] is a real number.

- D. [tex]\((-256)^{1/8}\)[/tex] is not a real number.

In how many ways can 50 cards be chosen from a standard deck of 52 cards?

Answers

The answer must take into account that the order is irrelevant, that is that it is the same J, Q, K that Q, K, J, and K, J, Q and all the variations of those the three cards.

The number of ways you can draw 50 cards from 52 is 52*51*50*49*48*47*...4*3 (it ends in 3).
,
But the number of ways that those 50 cards form the same set repeats is 50! = 50*49*49*47*....3*2*1

So, the answer is (52*51*50*49*48*....*3) / (50*49*48*...*3*2*1) = (52*51) / 2 = 1,326.

Note that you obtain that same result when you use the formula for combinations of 50 cards taken from a set of 52 cards:

C(52,50) = 52! / [(50)! (52-50)!] = (52*51*50!) / [50! * 2!] = (52*51) / (2) = 1,326.

Answer: 1,326

Jan is twice as old as her sister betty, but half of joe's age. betty just got married. how old is joe most likely to be?

Answers

For this algebraic problem, you have to assign variables so you can formulate equations to help you solve the problem. Let x be the age of Jan, y be the age of Betty and z be the age of Joe. You are to find the value of z. The equations would be:

x = 2y and x = 0.5z

Equating this two yields 2y = 0.5z. There are two variables but only one equation. Therefore, you have to specify one of the variables to be able to solve this problem. It was mentioned that Betty just got married. Let's assume that Betty's age was around 30 years old. Then, it follows that y=30. Substituting this to the final equation,

2(30) = 0.5z
z = 120 years old

This is impossible. Betty must have been married at an early age. Let's assume that Betty is 18 years old, then

2(18) = 0.5z
z = 72 years old

If Betty was 18 years old, then Joe is 72 years old. This is only an illustration to the problem. You must have introduced Betty's age to know the exact answer for Joe's age.

B is the midpoint of AC, D is the midpoint of CE. BD=10, and AE =2x. Find the length of CE if CD =3x

Answers

There is a theorem that states that the line joining two midpoints in a triangle is always parallel to the third side and its length is half the length of the third side.

Since B is midpoint of AC and D is midpoint of CE, therefore, BD is parallel to AE and BD = 0.5 AE
AE = 2 BD = 2 x 10 = 2x
Therefore, x= 10

D is the midpoint of CE and CD = 3x, therefore CE = 6x where x = 10
Based on this, CE = 6 x 10 = 60 units of length
