The next decimal number should be changed to hexadecimal. Your final response may contain up to six fractional digits. In decimal 386210, subscript 10 to F16.

F16 is 001000011000.1111. 218. F716 is 001000011000.111101112. 710 = (h0)16 = 716 is how the hexadecimal number is represented. It is necessary to add a 1 to the left and modify the number for both to 0. In base-2, the numeral 15 is represented as 1111, and the number 16 is represented as 10000. The greatest value in base-16 is the letter F, in a similar vein. such that 10 is the new value.

Binary 10 equals 1010, thus. Dividing 10 by 2 successively until the quotient equals 0 will yield the decimal to binary equivalent. By writing the remainder in each division step from bottom to top, it is possible to determine the binary equivalent.Base-16 is the definition given to hexadecimal. There are many powers of 16 in each place value in the number. The hexadecimal numbers are: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. 10 through 15 are represented, accordingly, by the letters A through F.

Answer:

You have 164 stamps.

Step-by-step explanation:

Let the no. of my stamps be 'x'

Half of x subtracted by 26 = 56

\(\frac{1}{2} x\) - 26 = 56

\(\frac{1}{2} x\) = 56 + 26 =  82

\(x\) = 82 x 2 =  164

Let's check

\(\frac{164}{2}\) - 26 = 56

\(\frac{164}{2}\) = 56 + 26

164     = 82 x 2

164 = 164!

The shape represents an isosceles trapezoid

The value of CP is 1.1 units

The given parameters are:

The diagonals of an isosceles trapezoid are congruent.

This means that:

\(CA = BD = 2.8\)

Also, we have:

\(CA = CP + AP\)

Substitute values for CA and AP

\(CP + 1.7 = 2.8\)

Subtract 1.7 from both sides

\(CP = 1.1\)

Hence, the value of CP is 1.1 units

Answer:

2√2 units.

Step-by-step explanation:

To find the length of the line joining points A(3, 5) and B(1, 3), we can use the distance formula. The distance formula is given by:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Substituting the coordinates of points A and B into the formula, we have:

d = sqrt((1 - 3)^2 + (3 - 5)^2)

  = sqrt((-2)^2 + (-2)^2)

  = sqrt(4 + 4)

  = sqrt(8)

  = 2sqrt(2)

Therefore, the length of the line joining points A and B is 2√2 units.

Step-by-step explanation:

a) If \(\mu_1\) is the average learning rate of the 6th graders without background noise level and \(\mu_2\) is the average learning rate of the 6th graders with background noise level

The Null Hypothesis is that the learning rate of the 6th graders is not affected by the background noise level.

Null hypothesis, \(H_0: \mu_1 = \mu_2\)

b) The Alternative Hypothesis is that the learning rate of the 6th graders is affected by the background noise level.

Alternative hypothesis, \(H_a: \mu_1 \neq \mu_2\)

c) Assumptions that must be met about the data before she can correctly use independent t-test

There must be random selection of the 6th graders

That the two groups are normally similar in their learning abilities

The division of students into the two groups should be at random

d) She has to  make these assumptions to prevent bias and inaccuracy of results. If these assumptions are not made, the outcome of the experiment may not reflect the true effect of background noise on the learning of the 6th graders.

She can still get accurate results if she include some bias in the selection to prove a particular result.

Answer:

$11988

Step-by-step explanation:

Given that,

The unit cost is given by :

\(C(x)=0.7x^2-462x+88218\)

We need to find the minimum unit cost.

For minimum cost,

Put \(\dfrac{dC}{dx}=0\)

So,

\(\dfrac{d}{dx}(0.7x^2-462x+88218)=0\\\\1.4x-462=0\\\\x=\dfrac{462}{1.4}\\\\x=330\)

Put x = 330 in equation (1).

\(C(330)=0.7(330)^2-462(330)+88218\\\\=\$11988\)

So, the minimum unit cost is equal to $11988.

Option A: The subjects are numbered 1–50 and these numbers are put into a random number generator. The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the current model.

Step-by-step explanation:

We are told that Twenty - five runners will receive a pair of the new model and the remaining 25 will receive a pair of the current model.

Now, a completely randomized design is defined as one where the treatments will be assigned completely at random in such a manner that each experimental unit will posses the same chance of receiving any of the treatments given.

To this effect, the most likely answer will be picking people at random to assign either the new model or current model.

This is usually done by making a list of the treatment combinations and then assigning a random number to each subject.

Looking at the options, the most appropriate will be option A.

Answer:

Step-by-step explanation:

To write y as a function of x using the given functions, we can substitute the value of "a" in the first equation with the expression "-5x + 1" from the second equation.

Given:

y = -3a + 3

a = -5x + 1

Substituting the value of "a" in the first equation:

y = -3(-5x + 1) + 3

Now, let's simplify this expression:

y = 15x - 3 + 3

y = 15x

Therefore, y can be expressed as a function of x as:

y = 15x

Floyd needs 33 matches to make a rectangle with a length of 20 matches.

To find out how many matches Floyd needs to make a rectangle with a length of 20 matches, we can observe a pattern in the given information.

From the given data, we can see that as the length of the rectangle increases by 4 matches, the number of matches used increases by 8. This means that for every additional 4 matches in length, Floyd requires 8 more matches.

Using this pattern, we can calculate the number of matches needed for a rectangle with a length of 20 matches.

First, we need to determine the number of 4-match increments in the length of 20 matches. We can do this by subtracting the starting length of 3 matches from the target length of 20 matches, which gives us 20 - 3 = 17.

Next, we divide the number of 4-match increments by 4 to determine how many times Floyd needs to add 4 matches. In this case, 17 ÷ 4 = 4 with a remainder of 1.

Since Floyd requires 8 matches for each 4-match increment, we multiply the number of increments by 8, which gives us 4 × 8 = 32 matches.

Finally, we add the remaining matches (1 match in this case) to the total, resulting in 32 + 1 = 33 matches needed to reach a length of 20 matches.

The x - intercept (s) is x = \(\sqrt[3]{\frac{4}{5} }\) and y - intercept (s) is -72

Given,

In the question:

The function is given as :

Consider f(x) = 3x² 30x - 72.

To find the x-intercept(s) and y-intercept of f(x).

Now, According to the question:

f(x) = 3x²× 30x - 72.

f(x) = 90\(x^{3}\) - 72

Solve the equation:

90\(x^{3}\) = 72

Make the leading coefficient of the variable one

\(x^3 = 72/90\\\)

Cross out the common factor

\(x^3\) = 4/5

Take the n-th root on both sides:

x = \(\sqrt[3]{\frac{4}{5} }\)

To find the y - intercept(s)

f(x) = 3x²× 30x - 72.

Set x = 0

f(0) = 3 × 0 × 30 × 0 - 72

f(0) = - 72

Hence, The x - intercept (s) is x = \(\sqrt[3]{\frac{4}{5} }\) and y - intercept (s) is -72

And, next week you practice for the same number of hours.

Same number = (3 1/4 + 2 1/2 + 1)

Which expression correctly shows how to solve this problem

Solve:

Knowing that you practice for 3 1/4 on Monday, 2 1/2 hours on Tuesday and 1 hour on Wednesday. Next week you practice the same. Thus, we can know that [C} \(\left(3\frac{1}{4}+2\frac{1}{2}+1\right)+\left(3\frac{1}{4}+2\frac{1}{2}+1\right)\) is the correct answer.

Solution if needed.

\(\left(3\frac{1}{4}+2\frac{1}{2}+1\right)+\left(3\frac{1}{4}+2\frac{1}{2}+1\right)\)

\(=\left(\frac{13}{4}+\frac{5}{2}+1\right)+\left(3\frac{1}{4}+2\frac{1}{2}+1\right)\)
