Answer:

There are two possible values: MN=5 or MN=19

Step-by-step explanation:

The points L and N are collinear, so we can visualize them on a right line as in Figure 1.  

First suppose that M is between L and N as in Figure 2. Then we can compute the distance between L and N as LN=LM+MN. Substracting LM from both sides, we obtain that MN=LN-LM=12-7=5.

For the other possibility, suppose that M is not between L and N as in Figure 3. Because LM<LN, it's impossible that M is located further to the right than N. Then M isn't at the right of L. Therefore, M is at the left of L, so L is between M and N, so the distance between M and N is given by MN=ML+LN=LM+LN=7+12=19.

When points L, M, and N are collinear and LM=7 and LN=12, the possible values of MN are 5 or 19 depending on the arrangement of the points. If the order is L, M, N then MN = 5 while if the order is L, N, M then MN = 19.

In mathematics, collinear points are points that lie on the same line. In your question, three points L, M, and N are collinear. Given that LM = 7 and LN = 12, we want to find the possible length of segment MN.

There are two possibilities based on the relative placement of these points:

The exponential equation representing the situation is A = A₀ * (0.5)^(t/h). The half-life of this substance is approximately 67 minutes.

To represent the radioactive decay of the substance, we can use the exponential decay model:

A = A₀ * (0.5)^(t/h)

where A is the amount of the substance at time t, A₀ is the initial amount, h is the half-life, and t is the time elapsed.

In this case, we have:

250 = 32 * (0.5)^(250/h)

To find the half-life, we can rearrange the equation:

(0.5)^(250/h) = 250/32

Take the logarithm of both sides:

(250/h) * ln(0.5) = ln(250/32)

Solve for h:

h = (250 * ln(0.5)) / ln(250/32)

Using a calculator, we find that h is approximately 67 minutes.

The radioactive decay of a substance is an exponential process represented by the equation [tex]N = N0 * e^(^-^k^t^)[/tex]. In this case, the half-life of the substance, or the time it takes for half the substance to decay, is approximately 66 minutes.

The subject matter at hand is related to the decay of a radioactive substance and its half-life. It's important to understand that the decay of radioactive material is an exponential process.

This can be represented with an equation of the form [tex]N = N0 * e^(^-^k^t^)[/tex], where N is the remaining amount of the substance, N0 is the initial amount, k is the decay constant, and t is time. In this given scenario, the scientist starts with 250 grams of the substance, and after 250 minutes, only 32 grams are left. Hence, we have [tex]32 = 250 * e^(^-^k^ *^ 2^5^0^)[/tex].

To find the half-life, we use the equation T = ln(2) / k, where T is the half-life. By solving these equations, we get the half-life to be approximately 66 minutes. Here the term 'half-life' is defined as the time it takes for half of the substance to decay; hence when the substance has gone through one half-life, only 50% of it would remain.

Answer:

With replacement

 21C2 = 210 outcomes

without replacement

20C2 = 190 outcomes

Step-by-step explanation:

For determining the number of possible outcomes you need count the number of possible combinations, because a combination is a selection of a number of items from a set of items where the order of selection does not matter.

The number of possible combinations is calculated thus

nCr = [tex]\frac{n!}{(n-r)!r!}[/tex]

           Where n: number of items of the set

                        r: number of selected items

a) If the group of states are selected with replacement then

   (n+r-1)Cr  

   n = 20 states

   r = 2 states

  then n +r -1 = 20 +2 -1 = 21

  21C2 = [tex]\frac{21!}{(21-2)!2!} = 210[/tex]

b) If the group of states are selected without replacement then

 nCr

 n = 20

 r = 2

20C2 = [tex]\frac{20!}{(20-2)!2!} = 190[/tex]

When two states are chosen with replacement from 20, there are 400 possible outcomes. Without replacement, there are 380 possible outcomes.

The question asks for the number of possible outcomes if two states are selected at random from a group of 20 states, with and without replacement. Replacement means a state can be chosen more than once, while without replacement means a state can only be chosen once.

When selecting with replacement, a state can be chosen, replaced, and then chosen again. Therefore, for each of the two selections, there are 20 possible states that can be chosen. This leads to a total of 20 * 20 = 400 possible outcomes.

In the scenario where states are chosen without replacement, the number of possible outcomes changes for the second selection because a state cannot be chosen twice. In this case, there are 20 options for the first state and 19 options for the second (since one state has been selected and is not replaced). Thus, the total number of possible outcomes is 20 * 19 = 380.

Answer:  The proof is done below.

Step-by-step explanation:  We are given to prove that the following statement is true :

"For every natural number n, [tex]n^5+4n[/tex] is a multiple of 5."

We will prove the above statement by MATHEMATICAL INDUCTION.

Let n = 1. Then, we get

[tex]n^5+4n=1^5+4\times5=5,[/tex] a multiple of 5.

Let n = 2. Then, we get

[tex]n^5+4n=2^5+4\times2=40,[/tex] a multiple of 5.

Let the statement be true for n = m, where m is a natural number.

So,

[tex]m^5+4m=5k,[/tex] for any natural number k.

Then,

[tex](m+1)^5+4(m+1)\\\\=m^5+5m^4+10m^3+10m^2+5m+1+4m+4\\\\=(m^5+4m)+5m^4+10m^3+10m^2+5m+5\\\\=5k+5(m^4+2m^3+2m^2+m+1)\\\\=5(k+m^4+2m^3+2m^2+m+1),[/tex] which is a multiple of 5.

Therefore, if the statement is true for n = m, then it is true for n = m+1.

That is, the statement is true for all natural numbers n.

Hence proved.

Annie paid 12800 pounds at end of 10 years

Solution:

Given that Annie borrows 8000 pounds at simple interest rate of 6 %

She also agrees to pay the loan back over a 10 year period

To find: total money paid back at the end of 10 years

The total amount paid is given as:

Total amount = simple interest + principal amount borrowed

The simple interest is given as:

[tex]S.I = \frac{pnr}{100}[/tex]

Where, "p" is the principal sum

"n" is the number of years

"r" is the rate of interest

Here, p = 8000 ; r = 6 % ; n = 10 years

[tex]S.I = \frac{8000 \times 10 \times 6}{100}\\\\S.I = 4800[/tex]

Therefore total amount paid at end of 10 years is:

Total amount = 4800 + 8000 = 12800

Thus Annie paid 12800 pounds at end of 10 years

Final answer:

Annie will pay a total of 12800 pounds at the end of 10 years for her loan of 8000 pounds with an annual simple interest rate of 6%.

Explanation:

To calculate the total amount of money Annie will have paid back at the end of 10 years on her loan of 8000 pounds with an annual simple interest rate of 6%, we first need to find the total interest she will pay over the period. Simple interest can be calculated using the formula: Interest = Principal × Rate × Time. In this case, the Principal (P) is 8000 pounds, the Rate (r) is 6% or 0.06 as a decimal, and the Time (t) is 10 years.

Interest = P × r × t = 8000 × 0.06 × 10 = 4800 pounds

The total amount of interest Annie will pay over 10 years is 4800 pounds. To find the total repayment amount, we add this interest to the original loan amount.

Total repayment = Principal + Interest = 8000 pounds + 4800 pounds = 12800 pounds

At the end of 10 years, Annie will have paid back a total of 12800 pounds.

Answer:

This statement is true

Step-by-step explanation:

Remember that subset F of a metric (or topological) space X is said to be closed if X-F is open according to the metric (topology) of F.

Let F⊆X. For the "if" part, suppose that [tex]F=F_1\cap F_2\cap \cdots \cap F_n[/tex] where [tex]F_k[/tex] is a closed set for all k. Then by De Morgan's law, [tex]X-F=(X-F_1)\cup(X-F_2)\cup \cdots\cup(X-F_n)[/tex].

Now, since Fk is closed for all k, then X-Fk is open. In every metric (topological) space, the union of an arbitrary family of open sets open sets is open, thus X-F is open, that is, F is closed.

For the "only if" implication, suppose that F is closed. We always have that F=F∩F (y∈F if and only if y∈F and y∈F if and only if y∈F∩F). then F is a finite intersection of closed sets (F and F).

Answer:option C is the correct answer

Step-by-step explanation:

f(x) = 36x^5 − 44x^4 − 28x^3

g(x) = 4x^2

We want to determine f(x)/g(x). It becomes

(36x^5 − 44x^4 − 28x^3) /(4x^2)

Looking at the numerator, each term in the numerator can divide the term in the denominator without remainder. it means that the term in the denominator is a common factor of the numerator and thus, 4x^2 can be factorized out of the numerator. It becomes

4x^2(9x^3 − 11x^2 − 7x) /(4x^2)

4x^2 in the numerator cancels out 4x^2 in the denominator. It becomes

Answer:

[tex]P(pitcher)=\frac{20}{53}=0.377[/tex]

Step-by-step explanation:

Data given

Infielders: Outfielders = 7:4

Pitchers:Outfielders= 5:3

We can find a ratio in common for the 3 cases and in order to do this we can put the ratio with the same denominator of outfielders and we can do this:

Infielders:Outfielders x3 = 7:4 *3 = 21:12

Pitchers:Outfielders x4= 5:3 *4 = 15:12

And we have a one combined ratio:

Infielders:Outfielders:Pitchers = 21:12:20

And we have a basis or a total of 21+12+20 =53

And then we can find the probability that we select a pitcher like this:

[tex]P(pitcher)=\frac{20}{53}=0.377[/tex]

The probability of selecting a pitcher from the baseball team is approximately 0.3774 or 37.74%, found by establishing the combined ratio of all players and then calculating the ratio of pitchers to the total number of players.

To determine the probability of selecting a pitcher from the county-wide baseball team, we first need to establish the ratio of all players in their respective categories based on the given ratios. The ratio of infielders to outfielders is 7:4, and the ratio of pitchers to outfielders is 5:3. We should find a common multiple for the number of outfielders in both ratios so that we can combine them into a single ratio that includes infielders, outfielders, and pitchers.

Let's assume there are 12 outfielders which is a common multiple of both 4 and 3 (the numbers of outfielders in each provided ratio). This would give us 7*3 infielders and 5*4 pitchers when we scale the ratios accordingly.

Therefore:

Infielders = 7 * 3 = 21

Outfielders = 12 (our common multiple)

Pitchers = 5 * 4 = 20

The total number of players on the team would be 21 + 12 + 20 = 53.

The probability of selecting a pitcher would therefore be the number of pitchers divided by the total number of players:

P(Pitcher) = Number of Pitchers / Total Number of Players = 20 / 53.

The probability of selecting a pitcher is approximately 0.3774 (or 37.74%).

Answer:

And we have to find the time after 8 minute and 25 second

After 8 minutes time will be 51+8 = 59 minutes

So after 8 minutes time will be 11:59:35

And after 25 second time will 25 +35 = 60 sec

60 sec = 1 minute

So after 8 minutes and 25 sec time will be 11:59:35 plus 25 sec = 12:00
