3x2 - 5xy + 2 + xy + x2 - 6y2
where x = 2 and y = -3

Answer:

p = 63

Step-by-step explanation:

Stage 1: Simplify the two sides of the condition.  

18−0.5p=−13.5  

18+−0.5p=−13.5  

−0.5p+18=−13.5  

Stage 2: Subtract 18 from the two sides.  

−0.5p+18−18=−13.5−18  

−0.5p=−31.5  

Stage 3: Divide the two sides by - 0.5.  

−0.5p  

−0.5 =  −31.5 , −0.5  

p=63

Answer:

(g · h)(t) = -6t - 6

Step-by-step explanation:

To find (g · h)(t), multiply g(t) by h(t).

g(t) = 3t + 3

h(t) = -2

(g · h)(t) = (-2)(3t + 3)

(g · h)(t) = -6t - 6

Answer:

7

Step-by-step explanation:

Positive integer = k

If Arden's Grandpa multiplies the integer by the number 1357, or will become 1375 × k = 1375k

If he ends up with a four digits result of 9502, to get the least value of k that will make it work, we will equate 1357k to 9502.

1357k ≥ 9502 (since we need the least value, this also means k can be greater than this value).

Divide both sides by 1357

1357k ≥ 9502

1357k/1357 ≥ 9502/1357

k ≥ 7.00

Hence the smallest value of k that will make this work is 7

Answer: 55 senior tickets

Step-by-step explanation:

The tickets that were sold to senior citizen is 55.

When two or more equations are solved together and the solution satisfies all the equation , then the set of equation are termed as system of equations.

It is given in the question that

A movie theater has 400 seats

Tickets at the theater cost

$8 for students

$7 for senior citizens

$10 for adults

All the tickets were sold

Total revenue made from sales = $3,535

If the number of adult tickets sold was 10 less than the number of student and senior tickets combined

Let the ticket sold to students = x

Sold to senior citizen = y

Sold to adults = z

z = (x+y) - 10

x+y+z = 400

x+y+x+y-10= 400

2(x+y) = 410

x+y = 205

z= 205-10

z = 195

8 *x +7*y +10*z = 3535

8x+7y +1950 = 3535

8x+7y = 1585

x+y = 205

8x+8y=1640

y =55

Therefore the tickets that were sold to senior citizen is 55.,

Answer:

The probability that exactly 97 of them finished the marathon​ is 0.221.

Step-by-step explanation:

We are given that in 2019, approximately 97.4% of all the runners who started the Boston Marathon were able to complete the 42.2 km race.

100 runners are chosen at random.

The above situation can be represented through the binomial distribution;

[tex]P(X = x) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x = 0,1,2,3,......[/tex]

where, n = number of trials(or samples) taken = 100 runners

           r = number of success = exactly 97

           p = probability of success which in our question is the probability

                 that runners finished the marathon​, i.e; p = 0.974

So, X ~ Binom(n = 100, p = 0.974)

Now, the probability that exactly 97 of them finished the marathon​ is given by = P(X = 97)

         P(X = 97) = [tex]\binom{100}{97} \times 0.974^{97} \times (1-0.974)^{100-97}[/tex]

                          = [tex]161700 \times 0.974^{97} \times 0.026^{3}[/tex]

                          = 0.221

Hence, the required probability is 0.221.

Using the binomial distribution, it is found that there is a 0.2207 = 22.07% probability that exactly 97 of them finished the marathon​.

For each runner, there are only two possible outcomes, either they finished the marathon, or they did not. The probability of a runner finishing the marathon is independent of any other runner, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that exactly 97 of them finished the marathon​ is P(X = 97), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 97) = C_{100,97}.(0.974)^{97}.(0.026)^{3} = 0.2207[/tex]

There is a 0.2207 = 22.07% probability that exactly 97 of them finished the marathon​.

Step-by-step explanation:

When reading challenging information, you should pay close attention to the diagrams, important points, visuals, etc. The answer to this question is D, or all of them, as a result.

Reading comprehension, vocabulary, phonics, fluency, phonemic awareness, and many other skills are important to keep in mind when reading. Each of them plays a unique part in any literary work.

Each and every reader must adhere to a number of requirements before reading. You must focus on the diagram first and foremost when conducting the survey because it quickly and efficiently interprets all of the data.
