Answer:

6. The word ‘COMMITTEE’ has 9 letters.

So it can be permuted in 9 ways, but we’ve got letters repeating there. To avoid the same arrangements happening again, we eliminate the repetitions.

M repeats twice. T Twice. E twice.

7. If it must be greater than  2000 , the first digit must either be  2  or  3 , which means you will have  2  choices. After that, there will be  3  choices for the second digit. Then there will be  2  choices for the third digit. Lastly there will be just  1  choice for the last digit.

The number of permutations becomes  2×3×2×1=12 .

Answer:

The word has 9 letters with 2 Ms, 2Ts and 2Es

We need 2 Ts together, this reduces the number of positions by one.

Answer:

The answer is 5 books.

m - the number of books sold on Monday

t - the number of books sold on Tuesday

w - the number of books sold on Wednesday

On Tuesday, she sold twice as many books as she did on Monday: t = 2m

On Wednesday, she sold 6 fewer books than she did on Tuesday: w = t - 6

During the three days Rachel sold 19 books: m + t + w = 19

t = 2m

w = t - 6 = 2m - 6

m + t + w = 19

______

Substitute t and w in the third equation:

m + 2m + 2m - 6 = 19

5m - 6 = 19

5m = 19 + 6

5m = 25

m = 25 : 5

m = 5

There are 34836480 number of 7-letter sequences (formed from the 26 letters in the alphabet, with repetition allowed) contain exactly one a and exactly two bs.

What is permutation?

A permutation of a set in mathematics is, broadly speaking, the rearrangement of its elements if the set already has an ordered structure into a sequence or linear order. The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."

In order to fix 7 − letter sequences (formed from the 26 letters in the alphabet, with repetition allowed) contains exactly one a and exactly two b, we know that For a sequence having n letters, it is called n letter sequence. Such sequences exist with 26^n cases with repetition of letters are allowed.

So, the number of desired cases are,

= \(\frac{7_P_3(24)^4}{2} = 34836480\)

Hence, there are 34836480 number of 7-letter sequences (formed from the 26 letters in the alphabet, with repetition allowed) contain exactly one a and exactly two bs.

Answer:

C. \( y = 2x + 3 \)

Step-by-step explanation:

A linear equation written in the slope-intercept form is represented as \( y = mx + b \).

The y-intercept is b.

The variable b on a graph is the point where the line cuts across the y-axis, for which the value of x is zero.

Therefore, the y-intercept of the graph given is 3. At this point where the line intercepts the y-axis, you can observe that the value of x = 0.

Therefore, the linear function, \( y = 2x + 3 \) has the same y-intercept as the graph, which is 3.

The value of ‘x’ rounded to the nearest hundredth is 84.97 feet.

Let the height of the totem pole be ‘h’ and the distance between the two people be ‘d’.Given: Height of the totem pole, h = 65 feetDistance between the two people, d = 200 feetAngle of elevation of the top of the totem pole from the person closest to it,

θ = 32°We need to find the value of ‘x’. From the given diagram, we can see that the distance between the person closest to the totem pole and the base of the totem pole can be given by:

Distance = h / tanθ = 65 / tan 32°= 115.03 Feel Now,

we can calculate the distance between the two people by adding this distance to ‘x’.

Therefore, d = 115.03 + x Solving for ‘x’,

we get : x = d - 115.03x = 200 - 115.03x = 84.97 feet (rounded to the nearest hundredth)

Answer:

Step-by-step explanation:

the line is on the -1 on the x axis and the y axis

The solution to the Bernoulli equation is given by:

ln|y| + 3/y = -2/(x + 2) + C.

To solve the Bernoulli equation (x + 2)y - 3y = (x + 2)^y^3, we can use the substitution method.

Let's make the substitution v = y^(1-3) = y^-2.

Taking the derivative of v with respect to x gives:

dv/dx = -2y^-3 * dy/dx.

Now, substitute v and dv/dx into the equation:

(x + 2)y - 3y = (x + 2)^y^3.

(x + 2)y - 3y = (x + 2)^(-2) * (-2y^-3) * dy/dx.

Simplifying the equation, we get:

(x + 2)y - 3y = -2(x + 2)^(-2) * y^-3 * dy/dx.

Divide both sides of the equation by (x + 2)y^3 to get:

1 - 3y^(2-3) = -2(x + 2)^(-2) * y^-2 * dy/dx.

Simplifying further:

1 - 3y^(-1) = -2(x + 2)^(-2) * y^-2 * dy/dx.

1 - 3/y = -2(x + 2)^(-2) * 1/y^2 * dy/dx.

1 - 3/y = -2/y^2 * (x + 2)^(-2) * dy/dx.

Now, we have a separable equation. Rearranging the terms:

1/y - 3/y^2 = -2/(x + 2)^2 * dy/dx.

Integrate both sides with respect to x:

∫(1/y - 3/y^2) dx = ∫(-2/(x + 2)^2) dy/dx dx.

The integral on the left side can be evaluated as:

ln|y| + 3/y = -2/(x + 2) + C,

where C is the constant of integration.

Answer:  multiple them  all together to get the answer

Step-by-step explanation:

The probability of getting at least 8 heads, assuming a binomial distribution with n = 10 and p(heads) = 0.30, is approximately 0.2338.

To find the probability of getting at least 8 heads in a binomial distribution with n = 10 and p(heads) = 0.30, we can calculate the probability of getting exactly 8, 9, and 10 heads and then sum them up.

Let's start by calculating the probability of getting exactly 8 heads:

P(X = 8) = C(10, 8) * (0.30)^8 * (0.70)^2

Where C(10, 8) represents the number of ways to choose 8 successes out of 10 trials, and (0.30)^8 * (0.70)^2 represents the probability of getting 8 heads and 2 tails.

Using the combination formula, C(10, 8) = 10! / (8! * (10 - 8)!), we can simplify the expression:

P(X = 8) = 45 * (0.30)^8 * (0.70)^2

Similarly, we can calculate the probability of getting exactly 9 heads:

P(X = 9) = C(10, 9) * (0.30)^9 * (0.70)^1

Using the combination formula, C(10, 9) = 10! / (9! * (10 - 9)!), we have:

P(X = 9) = 10 * (0.30)^9 * (0.70)^1

Lastly, the probability of getting exactly 10 heads:

P(X = 10) = C(10, 10) * (0.30)^10 * (0.70)^0

Using the combination formula, C(10, 10) = 10! / (10! * (10 - 10)!), which simplifies to 1:

P(X = 10) = 1 * (0.30)^10 * (0.70)^0

Now, to find the probability of getting at least 8 heads, we add the probabilities of these three cases:

P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)

Calculating the values for P(X = 8), P(X = 9), and P(X = 10) using the given values, we can find the probability of getting at least 8 heads.

Please note that the final value would depend on the calculations, and you can perform them to obtain the exact probability.
