Answer:

83 degrees

Step-by-step explanation:

For any given triangle, the angles inside have to equal 180 degrees.

knowing this, we can create an equation. We have 2 angles, and need to figure out the third.

180 = x + 44 + 53

180 = x + 97

x = 83

so x is 83 degrees.

The number 868 represents the final balance of the acount, then we conclude that the correct option is C.

"The value 868 represents the final balance in the account, which means the account ended with $868."

Weknow that the equation 868 = 700(1 + 0.04t) represents the amount of money earned on a savings acount.

We want to see what does 868 represent in this situation.

Where the form of the equation is:

money earned = function that depends on t.

So the value at the left, 868, just represents the final balance of the account, this is the amount of money that there is in the account at the end.

Thus, the correct option is C.

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

The probability of picking a green ball on the first pick, given that at least one red is chosen, is 11/19.

The probability of picking a green ball on the first pick, given that at least one red is chosen, can be calculated by finding the total number of possible outcomes and then dividing by the number of outcomes that include at least one red ball. In this bag, there are 11 green balls and 5 red balls, for a total of 16 balls. Since two balls are taken out successively without replacement, the total number of outcomes is 16 choose 2, or 120. Of those, there are 10 outcomes that include at least one red ball, so the probability of picking a green ball on the first pick, given that at least one red is chosen, is 11/19. This can be calculated by dividing the number of outcomes that include at least one red ball (10) by the total number of outcomes (120).

Answer:

\(\frac{2}{3}\)

Step-by-step explanation:

Probability (P) is calculated as

P = \(\frac{number}{count}\)

Since P(eclair) = \(\frac{1}{15}\) and there are 3 eclairs, then original probability before simplification must have been

\(\frac{3}{45}\)

meaning the total number of sweets is 45, so

3 + 2x + 6 + x = 45

3x + 9 = 45 ( subtract 9 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Then number of humbugs = 2x + 6 = 2(12) + 6 = 24 + 6 = 30

P(humbug) = \(\frac{30}{45}\) = \(\frac{2}{3}\)

Answer:

Step-by-step explanation:

Given two angles and the side between them, the first step must be to find the value of the third angle, the one opposite the given side. It will be ...

  B = 180° -A -C = 180° -109° -13° = 58°

Using this information and the Law of Sines, you can find the remaining sides.

  a/sin(A) = b/sin(B) = c/sin(C)

__

Then the missing sides are ...

  a = b(sin(A)/sin(B)) = 6(sin(109°)/sin(58°)) ≈ 6.6896

  c = b(sin(C)/sin(B)) = 6(sin(13°)/sin(58°)) ≈ 1.5915

The missing measures are ...

  B = 58°

  a = 6.6896

  c = 1.5915

Answer: make sure to round !!B = 58°

a = 6.7

kiran will take 48 minutes 16 x 3

mai will take 36 minuttes 13 x 3

Step-by-step explanation:

(1) Kiran will take 48 minutes to reach the end of a 12-mile bike path.

(2) Mai will take 36 minutes to reach the end of a 12-mile bike path.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Kiran rides 4 miles every 16 minutes.

Also, Mai rides 4 miles every 12 minutes.

To find the time taken by Kiran and Mai to reach 12 mile bike paths,

Use ratio property,

Time taken by Kiran to ride 4 miles = 16 minutes,

For 1 mile = 4 minutes,

For 12 miles = 12 x 4 = 48 minutes

Time taken by Mai to ride 4 miles = 12 minutes,

For 1 mile = 3 minutes

For 12 miles = 12 x 3 = 36 minutes.

Kiran will take 48 minutes and Mai will take 36 minutes to reach the end of a 12-mile bike bath.

The mean of the sample means, also known as the expected value of the sample mean, is equal to the population mean.

When all possible outcomes of size n are selected from a population and the mean of each sample is determined, the sample means to represent a sampling distribution. The mean of this sampling distribution denoted as the expected value of the sample means or simply the mean of the sample means, is equal to the population mean.

This result is derived from the concept of sampling. Each sample is a random selection from the population, and on average, these samples will reflect the characteristics of the population. Therefore, the mean of the sample means represents the average value that would be obtained if an infinite number of samples of size n were taken from the population. Since each sample mean is an unbiased estimator of the population mean, the mean of the sample means will be equal to the population mean. This property holds under certain conditions, such as when the sampling is random and independent.

Answer:

Step-by-step explanation:

The angles labeled with 2x, 4x, and 3x are on a straight line so their sum is equal to 180

2x + 4x + 3x = 180 add like terms

9x = 180 divide both sides by 9

x = 20

The angle represented with 3x - 30 and the angle represented with 2x + 10 are alternate and their measurement is same

3x - 30 = 2x + 10 export like terms to same side of the equation

3x - 2x = 10 + 30

x = 40

to find the angles replace x with the value found for each.

The value of c for which f '(/4) = 1 in the function f(x) = cx ln(cos x) is approximately c = -2.

To find the value of c, we first need to calculate the derivative of f(x) with respect to x. Using the product rule and the chain rule, we obtain:

f '(x) = c ln(cos x) - cx tan(x).

Next, we substitute x = π/4 into f '(x) and set it equal to 1:

f '(/4) = c ln(cos(/4)) - c(/4) tan(/4) = 1.

Simplifying the equation, we have:

c ln(√2/2) - c(1/4) = 1.

ln(√2/2) can be simplified to ln(1/√2) = -ln(√2) = -ln(2^(1/2)) = -(1/2) ln(2).

Now, rearranging the equation and solving for c:

c ln(2) = -1 + c/4.

c(ln(2) - 1/4) = -1.

c = -4/(4ln(2) - 1).

Calculating the approximate value, c ≈ -2.

Therefore, the value of c for which f '(/4) = 1 in the function f(x) = cx ln(cos x) is approximately c = -2.

When the number 410 is changed to 310 in the list of student numbers for the 10 schools in the district:

(a) The mean increases by 0.9.

(b) The median decreases by 7.

(a) The mean is calculated by summing up all the values and dividing by the total number of values.

Let's compare the mean before and after the change in the number 410.

Before the change:

Mean = (170 + 194 + 303 + 309 + 316 + 330 + 368 + 371 + 379 + 410) / 10 = 308

After the change (410 changed to 310):

Mean = (170 + 194 + 303 + 309 + 316 + 330 + 368 + 371 + 379 + 310) / 10 = 308.9

Comparing the mean before and after the change, we can see that the mean increases by 0.9.

(b) The median is the middle value of a sorted dataset. In this case, the median is the value that separates the lower half from the upper half when the numbers are arranged in ascending order.

Before the change:

Median = 316

After the change (410 changed to 310):

Median = 309

Comparing the median before and after the change, we can see that the median decreases by 7.

To draw the horizontal alignment for the curve on that shape on 12D, follow these steps:

Step 1: First of all, we have to determine the horizontal alignment for the curve. The horizontal alignment consists of a series of tangents, curves, and spirals.

Step 2: After that, we have to select the appropriate curve radius for the design speed, the superelevation, and the allowable sight distance.

Step 3: Next, plot the vertical curves with the curve layout. A design speed of 50 mph and a curve radius of 1200 ft will be used in this example.

Step 4: Next, we have to calculate the curve length using the formula Lc = Rθ. Here, Lc is the curve length, R is the radius, and θ is the curve angle. In this case, the curve angle is 4 degrees, so the curve length will be 83.775 ft.

Step 5: Then, we will plot the curve using a tangent-tangent-radius (TTR) method. The TTR method involves drawing a tangent to the curve's point of intersection, then drawing another tangent to the next point of intersection, and finally drawing the curve's arc with the given radius. This process is repeated until the curve's entire length is completed.

Step 6: Finally, label the horizontal and vertical curves, including the stationing and curve radius.

That's how we draw the horizontal alignment for the curve on that shape on 12D.
