The decimal value of 'z' after running the given code is 220.

The code initializes a short integer 'x' with the value -36, which is represented in binary as 11011100. Since the machine uses 1 byte for a short integer, 'x' is stored using 1 byte.

Then, 'x' is assigned to an integer 'y'. Since 'y' is an int, it uses 2 bytes to store the value. However, the binary representation of -36 (11011100) can be accommodated within the 2 bytes.

Finally, 'y' is cast to an unsigned int 'z'. The cast discards the sign bit, converting the value to its unsigned representation. Since 'z' is unsigned, it also uses 2 bytes to store the value. Therefore, the binary representation of -36 (11011100) is interpreted as a positive value, resulting in the decimal value 220.

In summary, the decimal value of 'z' is 220 because the negative value -36 is represented in binary as 11011100, which is interpreted as a positive value when cast to an unsigned int.

Answer:

first blank: 15

second blank: 90

Step-by-step explanation:

Obviously, sin and cos are related, but they are not the same thing. In order for them to be equal:

sin(____) = cos(75)

the angles have to add up to 90 (complementary)

What + 75 is 90?

Do a tiny calc:

90 - 75 is 15

The second question is stating the rule generically.

x + (90 - x) is 90

The type of indeterminate form obtained by direct substitution in the given limit is 1^∞, where 1^∞ is not a determinate form and its value is not always predictable.

Applying L'Hôpital's Rule to the limit, we get:

lim_(xâ0^+) [cos(Ï/2 - x)]^x = lim_(xâ0^+) e^[x ln(cos(Ï/2 - x))]

Now, applying L'Hôpital's Rule to the exponent, we get:

= lim_(xâ0^+) e^[x (-tan(Ï/2 - x))]

= e^0 = 1

Therefore, the limit is equal to 1.

Using a graphing utility to graph the function, we can see that the limit approaches 1 as x approaches 0 from the right side. Therefore, the result obtained using L'Hôpital's Rule is verified by the graph.

Given:

The areas of two similar squares are 16m² and 49m².

To find:

The scale factor of their side lengths.

Solution:

We know that the ratio of the areas of the similar squares is proportional to the ratio of square of there sides.

\(\dfrac{\text{Area of first square}}{\text{Area of second square}}=\dfrac{(\text{Side length of first square})^2}{(\text{Side length of second square})^2}\)

\(\dfrac{16\ m^2}{49\ m^2}=\dfrac{s_1^2}{s_2^2}\)

\(\dfrac{4^2}{7^2}=\left(\dfrac{s_1}{s_2}\right)^2\)

\(\left(\dfrac{4}{7}\right)^2=\left(\dfrac{s_1}{s_2}\right)^2\)

Taking square root on both sides, we get

\(\dfrac{4}{7}=\dfrac{s_1}{s_2}\)

\(\dfrac{s_1}{s_2}=\dfrac{4}{7}\)

Now, the scale factor is the ratio of side length of second square to the side length of first square.

\(k=\dfrac{s_2}{s_1}\)

\(k=\dfrac{7}{4}\)

Therefore, the scale factor of their side lengths is \(k=\dfrac{7}{4}\).

Step-by-step explanation:

The height of the shortest student is 155 cm and the height of the tallest student is 190 cm, then the inequality shows the range is 155 ≤ h ≤ 190. Hence, option B is correct.

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the provided data in the question,

The height of the shortest student is 155 cm and,

The height of the tallest student is 190 cm.

It means that the height rage is starting from 155 cm and ending at 190 cm.

The shortest height should be at least equal to 155 cm and the greater height is maximum 190 cm.

The probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

To find the probability that the average number of hours of overtime worked by a random sample of 140 employees exceeds 20 hours, we can use the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 18.9 hours and the population standard deviation is 7.8 hours, we can calculate the standard error of the mean using the formula: standard error = population standard deviation / sqrt(sample size).

For this problem, the sample size is 140, so the standard error is 7.8 / sqrt(140) ≈ 0.659.

To calculate the probability, we need to standardize the sample mean using the z-score formula: z = (sample mean - population mean) / standard error.

In this case, the sample mean is 20 hours, the population mean is 18.9 hours, and the standard error is 0.659. Plugging these values into the formula, we get z = (20 - 18.9) / 0.659 ≈ 1.71.

Now, we can use a standard normal distribution table or calculator to find the probability associated with a z-score of 1.71. Looking up this value in the table, we find that the probability is approximately 0.9564.

Therefore, the probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

The y-intercept of the graph of y = f(x) is y_int = 15. The x-intercepts of the graph are x_int = (3, 0) and x_int = (5, 0). The coordinates of the vertex of the parabola are (4, -1).

To find the y-intercept, we set x = 0 in the equation of the quadratic function f(x) = x^2 - 8x + 15:

f(0) = (0)^2 - 8(0) + 15 = 15

So, the y-intercept is at y = 15.

To find the x-intercepts, we set y = 0 in the equation:

x^2 - 8x + 15 = 0

We can factorize this quadratic equation:

(x - 3)(x - 5) = 0

Setting each factor to zero, we find the x-intercepts:

x - 3 = 0 --> x = 3

x - 5 = 0 --> x = 5

Therefore, the x-intercepts are at x = 3 and x = 5.

To find the coordinates of the vertex, we can use the formula for the x-coordinate of the vertex of a quadratic function given by x = -b/2a, where a and b are the coefficients of the quadratic function.

For our quadratic function f(x) = x^2 - 8x + 15, we have a = 1 and b = -8.

x = -(-8) / (2 * 1) = 8 / 2 = 4

Substituting x = 4 into the quadratic function, we find the y-coordinate of the vertex:

f(4) = (4)^2 - 8(4) + 15 = 16 - 32 + 15 = -1

So, the coordinates of the vertex are (4, -1).

The y-intercept of the graph of y = f(x) is y_int = 15. The x-intercepts are x_int = (3, 0) and x_int = (5, 0). The coordinates of the vertex of the parabola are (4, -1).

Answer:

3.) 0.894

Step-by-step explanation:

✔️First, find BD using Pythagorean Theorem:

BD² = BC² - DC²

BC = 17.89

DC = 16

Plug in the values

BD² = 17.89² - 16²

BD² = 64.0521

BD = √64.0521

BD = 8.0 (nearest tenth)

✔️Next, find AD using the right triangle altitude theorem:

BD = √(AD*DC)

Plug in the values into the equation

8 = √(AD*16)

Square both sides

8² = AD*16

64 = AD*16

Divide both sides by 16

4 = AD

AD = 4

✔️Find AB using Pythagorean Theorem:

AB = √(BD² + AD²)

AB = √(8² + 4²)

AB = √(64 + 16)

AB = √(80)

AB = 8.9 (nearest tenth)

✔️Find sin x using trigonometric ratio formula:

Reference angle = x

Opposite side = BD = 8

Hypotenuse = AB = 8.944

Thus:

\( sin(x) = \frac{opp}{hyp} = \frac{8}{8.944} = 0.894 \) (nearest thousandth)

The present value of the payments is smaller than the amount of the loan, so you will not be able to pay off the loan.

The present value of the payments refers to the current value of the future payments, considering the time value of money. In this case, the payments are made over a period of 8 months, and each payment is listed. To determine if the payments will be enough to pay off the credit card, we need to calculate the present value of these payments and compare it to the initial loan amount of $5,000.

Since the interest rate on the credit card is 1.5% per month, we need to discount each payment back to its present value. By discounting the payments, we can see the equivalent value of these payments in today's dollars. If the present value of the payments is equal to or greater than $5,000, it would be enough to pay off the loan. However, if the present value is smaller than $5,000, it means the payments will not be sufficient to pay off the loan.

In this case, without specific information about the discount rate used to calculate the present value, we cannot make an exact determination. However, based on the given information, which states that the present value of the payments is smaller than the amount of the loan, it suggests that the payments will not be enough to pay off the credit card debt.

A straight line PPF indicates constant opportunity costs in production is TRUE.

The Production-Possibility Frontier (PPF) is a graphical representation of the maximum amount of two goods that can be produced given a certain number of resources.

If the PPF is a straight line, then the opportunity cost of producing an additional unit of one good is the same regardless of how much of that good is already being produced. This means that the resources used to produce the two goods are perfectly substitutable and there are no increasing opportunity costs.

However, if the PPF is a curved line, then the opportunity cost of producing an additional unit of one good increase as more of that good is produced. This is because the resources used to produce the two goods are not perfectly substitutable and there are increasing opportunity costs.

Answer:

The wheel completed a total of 212 turns.

Step-by-step explanation:

A wheel has a circular form, therefore its length is given by the following formula:

\(length = 2*\pi*radius\)

Where radius is half the diameter. Applying the data from the problem to calculate the length of the wheel gives us:

\(length = 2*\pi*(\frac{1.5}{2})\\length = 1.5*\pi = 4.7124\)

Since the engine traveled a distance of 1000 metres and each turn of the wheel has 4.7124 metres, in order to calculate the number of turns the wheel made in that course we need to divide both numbers as shown below:

\(turns = \frac{1000}{4.7124} = 212.21\)

X>0, so the second one

Step-by-step explanation:

Since the point on 0 is OPEN that means the number (0) is NOT part of the solution. Therefore, X is greater than 0.

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

                                            P = (-3.5, 1.25)

Hence, the coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25).

The null hypothesis in a one-way ANOVA test is that there is no treatment effect. This means that the mean scores of the groups being compared are not significantly different. The one-way ANOVA test is a statistical method used to compare the means of three or more groups.

The one-way ANOVA test requires that certain assumptions be met, including that the data is normally distributed and that the variances of the groups being compared are equal. If these assumptions are met, then the test can be used to determine whether there is a significant difference between the means of the groups. The test works by comparing the variability between the groups to the variability within the groups.

If the variability between the groups is larger than the variability within the groups, then it is likely that there is a significant difference between the means of the groups. The alternative hypothesis in a one-way ANOVA test is that there is some treatment effect, which means that at least one of the group means is different from the others.

If the null hypothesis is rejected, then the alternative hypothesis is accepted, and it can be concluded that there is a significant difference between the means of the groups. The one-way ANOVA test is useful for determining whether there is a significant difference between the means of several groups, but it does not provide information about which specific group means are different. To determine which group means are different, post hoc tests can be performed.

(a) To determine a nonzero vector orthogonal to the plane through the points P, Q, and R, we can first find two vectors in the plane and then take their cross product. Taking vectors PQ and PR, we have:

PQ = Q - P = (5, 1, -2) - (-4, 0, 0) = (9, 1, -2)

PR = R - P = (6, 4, 1) - (-4, 0, 0) = (10, 4, 1)

Taking the cross product of PQ and PR, we have:

n = PQ x PR = (9, 1, -2) x (10, 4, 1)

Evaluating the cross product gives n = (9, -17, 35). Therefore, (9, -17, 35) is a nonzero vector orthogonal to the plane through points P, Q, and R.

(b) To determine the area of triangle PQR, we can use the magnitude of the cross product of vectors PQ and PR divided by 2. The magnitude of the cross product is given by:

|n| = \(\sqrt\)((9)^2 + (-17)^2 + (35)^2)

Evaluating the magnitude gives |n| = \(\sqrt\)(811).
