Answer:

Hence the probability that are already owned are 0.943620

Step-by-step explanation:

Given:

No fo character sequences using either letter or digits had not been claimed=94696

To find :

What is probability that letter are already claimed ?

Solution:

We know that there are 26 alphabets  and digits are 0,1,2.. 9

Hence total will be of 36.

Now we are going to Arrange the sequence for all possible values

as there 4 characters we get ,each of them with 36 possible values

=36*36*36*36

=36^4

=1679616.

Now we have a sequence with 94696 character and digits are not claimed .

Its probability

=94696/1679616

=0.05637.

So the required probability will be ,

P(claimed)=1- P(Not claimed)

= 1-0.056379

=0.943620

Hence the probability that are already owned are 0.943620

Final answer:

(Option D)Mitchell's stipend was  $506.02.

Explanation:

To find out how much Mitchell's stipend was, we can subtract the amount he spent on textbooks from the amount he had left at the end of the semester.

Let's assume Mitchell's stipend was X dollars.

He spent $429.17 on textbooks, so the remaining amount would be X - $429.17.

We know that he had $77.85 left, so we can set up the equation:

X - $429.17 = $77.85

Now, we can solve for X:

X = $77.85 + $429.17 = $506.02

So, Mitchell's stipend was $506.02. This corresponds to answer (Option D).

Answer:

1 year:

The amount is $6695 and the interest is $195

2 years:

The amount is $6895.85 and the interest is $395.85.

The balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85 with an initial investment of $6500 with a 3% interest rate compounded annually.

The subject of this question is compound interest. When an amount of money is placed in an account with a certain interest rate, the amount grows over time. In this case, the initial investment is $6500 and the interest is compounded annually at a rate of 3%.

To calculate the total amount in the account after a certain period, you can use the following formula:

A = P(1 + r/n)^(nt)

A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time in years.

Applying this formula to the problem: for the end of first year, t=1, we will have:

A=6500(1 + 0.03/1)^(1*1) ≈ $6695

For the end of 2 years, t=2, we will get:

A=6500(1 + 0.03/1)^(1*2) ≈ $6899.85

Therefore, the balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85. Assume there are no withdrawals from the account during this period.

A tangent line intersecting with a radius always creates a  right angle.

A tangent line intersects with a circle at only one point.

This point is referred to as the point of tangency.

When a radius is drawn to intersect with the tangent line at the point of tangency, then the angle at that point of intersection is a right angle i.e. the measure of the angle is 90 degrees.

This is so because both lines (i.e. the radius and the tangent line) are perpendicular lines.

Hence, the text that completes the statement is right angle.

Answer: 9.16 feet

Step-by-step explanation:

Hi, to answer this question, since we have formed a right triangle (see attachment) we have to apply the Pythagorean theorem:

a2 +b2 = c2

Where c is the hypotenuse of a right rectangle (the longest side) and a and b are the lengths of the other 2 sides.

In this case the hypotenuse us the ladder.

So, replacing with the values:

4^2 + b ^2 = 10^2

16 + b^2 = 100

b^2 = 100-16

b^2 = 84

b = √84

b= 9.16 feet

Answer:

The answer is C(n,r) = n!/[(n-r)!r!]

The formula for the following conditions is  [tex]C(n,r) = \dfrac{n!}{[(n-r)!r!]}[/tex]

We can use combinations for this case,

A total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in a total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, a total number of choices, in that case, would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

Answer:

The answer is 32.

Step-by-step explanation:

Remember that order of operation is very important in this problem.

Substitute x for 3 and y for 2 in the equation.

When solving the first term, we must note that we have to square the 3 first before we multiply it by 4. So, 4(3)^2 is basically 36. To simplify the second term you just have to do 2*2, which is 4. 36-4=32, which is the answer.

Final answer:

The value of the expression 4x² - 2y when x = 3 and y = 2 is 32, found by substituting the values of x and y into the expression and simplifying.

Explanation:

To find the value of 4x² - 2y when x = 3 and y = 2, we need to substitute these values into the expression.

So, the value of the expression 4x² - 2y when x = 3 and y = 2 is 32.

Answer:

The average weight of okapi  is 290 kg

The average weight of llama is 160 kg

Step-by-step explanation:

To solve the question, we are to resolve the word problem as follows;

Let the average weight of Okapi be X

The average weight of llamas be Y

X + Y = 450 and

3 Y = X + 190

Solving the above simultaneous equation, we have

X = 450 - Y

∴ 3·Y = 450-Y+190

4·Y =640

Y = 160 and X = 450 - 160 = 290

Therefore, the average weight of okapi  = 290 kg while the average weight of llama = 160 kg.

The magnitude of the first duckling's displacement is 13 units, and for the second duckling it is approximately 15.3 units. The second duckling wandered 2.3 units farther than the first.

The student is asking about the displacements of two ducklings from their nest and how much farther one wandered than the other. To compare the displacements of the two ducklings, we calculate the magnitudes of their displacements using the Pythagorean theorem.

For the first duckling's displacement, with coordinates (12,5), the magnitude is
sqrt(122 + 52) = sqrt(144 + 25) = sqrt(169) = 13 units.

For the second duckling's displacement, with coordinates (13,-8), the magnitude is
sqrt(132 + (-8)2) = sqrt(169 + 64) = sqrt(233) = approximately 15.3 units.

The second duckling wandered farther by the difference in magnitudes, which is 15.3 units - 13 units = 2.3 units. Therefore, the second duckling wandered 2.3 units farther than the first duckling.

Step-by-step explanation:

Please kindly check the attached file for explanation

Answer: The probability of picking a green block or red block is 0.64 (or 64%)

Step-by-step explanation: The total number of blocks can be derived as;

31 (R) + 49(G) + 24(Y) + 21(P) = 125

With 125 blocks in total, there are 125 possibilities and the possibility of picking any of the four colors shall be be determined as a fraction of the entire possible outcomes.

The probability of picking a green ball when picked at random is given as;

P(Green) = Number of required outcomes ÷ Number of all possible outcomes

P(Green) = 49/125

(Note that there are 49 green blocks and a total of 125 blocks of all four colors)

Also the probability of picking a red ball when picked at random is given as;

P(Red) = Number of required outcomes ÷ Number of all possible outcomes

P(Red) = 31/125

The probability of picking a green block or a red block is given as P(green or red)

P(Green or Red) = 49/125 + 31/125

P(Green or Red) = 80/125

P(Green or Red) = 16/25

P(Green or Red) = 0.64

Therefore the probability of picking a green or red block at random is 0.64 or 64%

If you plug it all in you will get x=2 x=-3

Step-by-step explanation:

The quadratic formula is

-b+/-[tex]\sqrt[/tex]-b^2-4ac all over 2(a)

your equation 2x^2+2x-12

you can label it

a=1      b=2               c=-12

If you plug it all in and solve you will get x=2 x=-3

The values of x would be 2 and 3 which are determined by using the quadratic formula to solve the given quadratic function.

The quadratic function is defined as a function containing the highest power of a variable is two.

We have been given that quadratic function as

2x² + 2x - 12

Compare the given function to the standard quadratic function f(x) = ax² + b x + c.

We get a = 2, b = 2 and c = -12

Using the quadratic formula to solve the above quadratic function

[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Substitute the values of  a = 2, b = 2 and c = -12 in the quadratic formula,

[tex]x = \dfrac{-2\pm\sqrt{2^2-4\times2\times-12}}{2\times2}[/tex]

[tex]x = \dfrac{-2\pm\sqrt{4+96}}{4}[/tex]

[tex]x = \dfrac{-2\pm\sqrt{100}}{4}[/tex]

[tex]x = \dfrac{-2\pm10}{4}[/tex]

x = (-2+10)/4 and x = (-2-10)/4

x = (8)/4 and x = (12)/4

x = 2 and x = 3

Therefore, the values of x would be 2 and 3 which are determined by using the quadratic formula to solve the given quadratic function.
