Answer:

x = 25

Measure of each angle label is 42°

Step-by-step explanation:

(x + 17)° and (3x - 33)° are the expressions of the two vertical angles formed by the intersection of two straight lines. Vertical opposite angles are congruent. Therefore:

x + 17 = 3x - 33

Solve for x. Collect like terms

17 + 33 = 3x - x

50 = 2x

Divide both sides by 2

50/2 = 2x/2

25 = x

Measure of the two angles are:

x + 17 = 25 + 17 = 42° (substitution)

3x - 33 = 3(25) - 33 = 75 - 33 = 42°

Answer:

  the correct answer is marked (1/2)

Step-by-step explanation:

The average rate of change is the slope of the line between the two points at the ends of the interval.

  m = (g(3) -g(-4))/(3 -(-4))

The values of the function we need are ...

  g(3) = 5/(3-1) +2 = 2.5 +2 = 4.5

  g(-4) = 5/(-4-1) +2 = -1 +2 = 1

So, the slope is ...

  m = (4.5 -1)/7 = 3.5/7 = 1/2

The average rate of change is 1/2.

Answer:

The answer is below

Step-by-step explanation:

Let t1 be the arrival times between a packet and its immediate predecessor and t2 be the arrival times between a packet and successor. Let L1 be the lengths of the predecessor packet and L2 the length of the packet itself. Therefore:

P(no collision between packet and predecessor or successor) = [tex]P(t_1>L_1)P(t_2>L_2)[/tex]

If P1 is the probability that there is no collision with preceding packets, hence:

P(no collision with other packets) = [tex]P_1*P(t_2>L_2)[/tex]

λ = 10 packets/s, fixed packet length = 20 ms = 0.02 s. Hence:

[tex]P(t_1>L_1)=P(t_2>L_2)=e^{-\lambda *0.02}=e^{-10*0.02}=e^{-0.2}[/tex]

P(no collision between packet and predecessor or successor) = [tex]P(t_1>L_1)P(t_2>L_2)[/tex] = [tex]e^{-0.2}*e^{-0.2}=e^{-0.4}[/tex]

P(packet collides with either its predecessor or its successor) = 1 - P(no collision between packet and predecessor or successor) = [tex]1-e^{-0.4}=0.33[/tex]

If the transmission times change, the answer would also change.

answer:

minimum = 20 inches

maximum = 49 inches

Step-by-step explanation:

The height data in the question is

10 15 20 25 30 35 40 45 50.

From above we have the classes as:

10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49,

The minimum tree height bus from the first class. While the maximum tree height is from the last class.

The first class is 10-14, so the minimum height = 10 inches

The last class is 45-49 so the maximum height inches = 49 inches.

The maximum tree height from the classes I have grouped is 49 inches since 49 is the upper limit from the last class.

The minimum tree height is 10 inches

What does the check time part mean?

The number of different codes is 192.

It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.

We have,

The formula for combination is [tex]^nC_r[/tex] = n! / r! (n -r)!

Now,

Total numbers = 25

n = 25

Required numbers of code = 3

Now,

The number of different codes.

= [tex]^{25}C_3[/tex]

= 25! / 3! (25 - 3)!

= 25 x 24 x 23! / 3 x 2 x 23!

= 25 x 24 / 3 x 2

= 24 x 8

= 192

Thus,

The number of different codes is 192.

Answer:

5 gallons of the 10% fructose solution.

15 gallons of 20% fructose solution

Step-by-step explanation:

You basically have an equation

Some amount of 10% solutions and some amount of 20% are to be combined to get to 17.5

So we can label those two amounts x and y, x being 10% and y being 20%.

We know that x + y (in gallons) must be equal to 20 gallons, so we can do this

x+y = 20

y = 20-x.

Then we can multiply x by 10% = 0.1x, 20-x by 20% which makes 4-0.2x

Then we know that the end result must be 20 gallons of 17.5% so we can multiply those two to get 3.5

Then we can add all of our results.

0.1x + 4 - 0.2x = 3.5

Solve for x

-0.1x = -0.5

x = 5

Now we have what x is, so we now know that there was 5 gallons of the 10% fructose solution.

Then we know that y = 20 - x so y is equal to 20 - 5 which is 15.

So that means that 15 gallons of 20% fructose solution was used.

So the answer is

5 gallons of the 10% fructose solution.

15 gallons of 20% fructose solution.

c. Include the date on each page of notes

Step-by-step explanation:

The main reason for her not being able to do this is because she did not include the date on each page of notes. Failing to do so means that she does not know which notes she took first and which ones she took later, therefore preventing her from correctly organizing the notes based on when they were taken (in the correct order). Neither the class title or the names of the guest speaker prevent her from organizing her notes in order, thus making the answer c.

Answer: It is c

Total Cost (in dollars) = a + c

Step-by-step explanation:

Algebra

When mathematics quantities are generalized into letters or variables, then we are dealing with algebra.

We are said the cost of an adult's ticket into a theme park is $a and a child's ticket costs $c. Since both quantities are unknown, we must treat them as variables and use the same logic procedure to solve the problem as if they were numbers.

The total cost for an adult and a child is the sum of both individual costs, thus

Total Cost (in dollars) = a + c
