step by step explanation -

well , the question asks us to find the difference between the two terms given as mixed fractions ~

tho it's not that difficult to simplify a problem in mixed fraction , but solving the problem by first converting it to an improper fraction reduces the risk of mistakes ! so let's do the question by that way ~

\(4 \frac{4}{5} - 3 \frac{2}{5} \\ \\ converting \: into \: improper \: fraction \: we \: get \\ \\ \implies \: \frac{5 \times 4 + 4}{5} \: \: - \: \: \frac{5 \times 3 + 2}{5} \\ \\ \implies \: \frac{24}{5} \: \: - \: \: \frac{17}{5} \\ \\ since \: the \: denominators \: are \: same \: we \: can \: simply \: subtract \: the \: terms \\ \\ \implies \: \frac{7}{5} \)

we're done with our solution tho , but since the options given are in mixed fraction , so let's convert the improper fraction , obtained as the answer , into a mixed fraction !

\( \frac{7}{5} = 1 \frac{2}{5} \\ \)

The values of `eax` and `edx` after the division takes place will depend on the specific architecture and the values of `eax` and `edx` before the division.

1. In the given code snippet, `eax` is set to 0x00007530 and `ecx` is set to 0x00002710. Since the `div` instruction performs unsigned division, it divides the double-word value formed by concatenating `edx` and `eax` by the value in the `ecx` register.

After the division, the quotient will be stored in `eax`, and the remainder will be stored in `edx`. However, note that dividing by zero will cause an exception, so the result will depend on whether `ecx` is zero or not.

2. The roles of `eax` and `edx` concerning the result of the `div` instruction are as follows:

  - `eax`: It holds the high-order 32 bits of the dividend. After the division, it will contain the quotient.

  - `edx`: It holds the low-order 32 bits of the dividend. After the division, it will contain the remainder.

3. In the given code, the `test edx, edx` instruction checks whether `edx` is zero or not. If `edx` is zero (the zero flag is set), the `jz` instruction will jump to the address `loc_00401044`.

If the `test` instruction was replaced with `test eax, eax`, it would check whether `eax` is zero or not. The jump will be taken (to `loc_00401044`) only if `eax` is zero, i.e., the zero flag is set.

The estimated IQR of the water bills for ten households in Gombak in September is RM44.80.

The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. A quartile is a statistical term describing a division of observations into four defined intervals based on the values of the data. The IQR is the range between the first quartile (Q1) and the third quartile (Q3).

IQR= Q3 - Q1

Where, Q3 is the third quartile, Q1 is the first quartile.

IQR for the given data can be calculated as follows

Arrange the data in ascending order.32.10, 45.70, 54.90, 65.50, 79.00, 87.70, 88.90, 98.00, 112.00, 132.60

Find the median of the given data.Q2 = (79.00 + 87.70) / 2Q2 = 83.35

Find the first quartile (Q1).It is the median of the lower half of the data set.Q1 = (54.90 + 65.50) / 2Q1 = 60.20

Find the third quartile (Q3).It is the median of the upper half of the data set.Q3 = (98.00 + 112.00) / 2Q3 = 105.00

Finally, use the formula to calculate the IQR.IQR = Q3 - Q1= 105.00 - 60.20= RM44.80

Thus, the estimated IQR of the water bills for ten households in Gombak in September is RM44.80.

The value of x in the side length of the right triangle is 15.

The diagram in the image is two similar right triangle.

From the image:

Base of smaller triangle = x

Height of the smaller triangle = 6

Base of larger triangle = ( x + 5 )

Height of the larger triangle = 8

To determine the value of x, we take the ratio of the sides of the two triangle since they similar:

Hence:

Base of smaller triangle : Height of the smaller triangle = Base of larger triangle : Height of the larger triangle.

Plug in the values:

x : 6 = ( x + 5 ) : 8

x / 6 = (x+5) / 8

Cross multiply:

8 × x = 6( x + 5 )

8x = 6x + 30

8x - 6x = 30

2x = 30

x = 30/2

x = 15

Therefore, the value of x is 15.

The 95% confidence interval for the true proportion of people who favor candidate is (0.419,0.481).

A random sample of 1000 people was condidered for testing.

Number of people in sample favoured candidate

= 450

So, sample proportion, p = 450/1000 = 0.45

Confidence level= 95% i.e, alpha = 1 - 0.95=0.05, From standard normal Z- table, the value of Z( 0.025) is equals to 1.96..

Confidence interval formula,

CL = p ± Z× √(p×(1-p)/n)

Lower bound of interval is ,

=0.45 - 1.96× √(0.45× (1-0.45)/1000)

= 0.45 - 1.96× √(0.45× 0.55/1000)

= 0.45 - 1.96× √(0.0002475)

=0.419165~ 0.419

So the Upper bound is

= p + Z×√(p×(1-p)/n)

= 0.45 + 1.96× √(0.45× (1-0.45)/1000)

= 0.45 + 1.96× √(0.0002475)

= 0.480835 ~0.481

Hence, the required confidence interval is (0.419,0.481).

B) 3b. 10b

Step-by-step explanation:

B) 3b. 10b = (3x10)(bxb) = 30b²

Slope Formula: (y2 - y1) / (x2 - x1)

Line 1: 3

Point 1 = (-5, -8)

Point 2 = (-1, 4)

Slope = (4 - - 8) / (-1 - - 5) = (4 + 8) / (-1 + 5) = 12 / 4 = 3

Line 2: 3

Point 1 = (0, 1)

Point 2 = (2, 7)

Slope = (7 - 1) / (2 - 0) = 6 / 2 = 3

Line 3: -1/3

Point 1 = (6, -7)

Point 2 = (-6, -3)

Slope = (-3 - - 7) / (-6 - 6) = (-3 + 7) / (-12) = 4 / -12 = -1/3

Parallel lines have the same slope, while perpendicular lines have an opposite reciprocal slope.

Line 1 and Line 2 are parallel because they have the same slope.

Parallel

Perpendicular

Perpendicular

Step-by-step explanation:

You need to learn this for some tests where you don't get access to the internet in most cases like the ACT, SAT, normal tests, ect.

The formula for slope is y2-y1   divided by x2-x1

y2 is a point from the second pair of points, for example (-1, 4) or (2, 7).

y1 is a point from the first pair like (-5, -8), or (0, 1).

You can plug in the values for example:

4 - (-8)  / -1 - (-5)

Two negatives equals a positive in math, so

12 / 4

= 3.

The slope for line 1 is 3.

You extend this to the other two lines.

For lines to be parallel, they must have the same slope.

1 and 2 should both have a slope of 3 based on the previous algebra, so they are parallel.

Line 3 has a slope of -1/3 which makes it perpendicular to 1 and 2, because perpendicular lines have the negative reciprocals of each other.

For example, if a line has a slope of 2, the perpendicular line has a slope of -1/2 because a reciprocal is the number flipped upside down with a fraction (aka, multiplying something with 1/x where x is the original number.)

A reciprocal slope of 19348 is -1/19348.

Therefore, the two unit vectors in which the directional derivative of f at (6,2) is equal to zero are:

v_1 = <-9/10, √(100/81)> ≈ <-0.707, 0.707>

v_2 = <-9/10, -√(100/81)> ≈ <-0.707, -0.707>

The directional derivative of a function f(x,y) at point (a,b) in the direction of a unit vector v = <u, v> is given by the dot product of the gradient of f at (a,b) and v:

D_v(f) = ∇f(a,b) · v

where ∇f(a,b) is the gradient of f at (a,b).

To find the unit vectors in which the directional derivative of f at (a,b) is equal to zero, we need to find the gradient of f at (a,b) and then solve for v such that D_v(f) = 0.

First, we find the gradient of f(x,y):

∇f(x,y) = <∂f/∂x, ∂f/∂y>

= <3x^2y-2xy^2, x^3-2xy>

Now, we evaluate the gradient at (a,b) = (6,2):

∇f(6,2) = <3(6)^2(2)-2(6)(2)^2, (6)^3-2(6)(2)>

= <204, 180>

Next, we solve for v such that D_v(f) = 0:

D_v(f) = ∇f(6,2) · <u, v>

= 204u + 180v

Setting D_v(f) = 0, we get:

204u + 180v = 0

u = -9/10 v

Since v is a unit vector, we have:

1 = ||<u, v>||^2

= u^2 + v^2

= (-9/10)^2v^2 + v^2

= (81/100)v^2

Solving for v, we get:

v = ± √(100/81)

v_1 = <-9/10, √(100/81)> ≈ <-0.707, 0.707>

v_2 = <-9/10, -√(100/81)> ≈ <-0.707, -0.707>

Recall that

(a + b)² = a² + 2ab + b²

We want to add a constant to the left side to be able to form a squared binomial. If we let a = x, then

2ab = 10x = 2 • x • 5

so that b = 5, which tells us

(x + 5)² = x² + 10x + 25

So, we add 25 to both sides of the equation to get

x² + 10x + 25 = 9 + 25

and we simplify both sides to end up with

(x + 5)² = 34

If you want to go on to solve for x, we have

x + 5 = ± √34

x = -5 ± √34

The first and second cars are 7724 feet apart from each other.

The angle of depression is the angle we have to move your eyes downwards to look at the car from the plane. Let's start with the first car, with the 31° angle of depression. Draw an upside-down right triangle with vertices at the plane, the car, and the point 3500 feet in the air above the car (level with the plane). The vertex at the plane is 31° and the right angle is the vertex in the air above the car. The length of the leg from the car to the point in the air above the car is 3500 feet. We like to find the length of the leg from the plane to the point in the air above the car. Since the two sides involved are the legs of the triangle, use tangent:

     tan = opposite/ adjacent

⇒  tan(31°) = 3500/x

⇒ 0.60086 = 3500/x

⇒ 0.67 x = 3500            [ rounding up 0.60086 = 0.67]

⇒ x = 5223.88

That means the first car is 5223.88 feet from the point on the highway below the plane.

We can do something similar with the second car, which has an angle of depression of 53° from the plane. Again, the leg from the car to the point in the air above the car (level with the plane) is 3500 feet, the right angle is at the vertex at the point in the air above the car, and the 53° angle is at the vertex at the plane. We are looking for the length of the other leg, which runs from the plane to the point in the air above the car. Use tangent:

    tan(53°) = 3500/x

⇒ 1.327 = 3500/x

⇒ 1.4x = 3500            [ rounding 1.327 = 1.4]

⇒ x = 3500/1.4
⇒ x = 2500

That means the second car is 2500 feet from the point on the highway below the plane.

Add the two distances together to get the total distance from car to car:

5223.88 + 2500.00 = 7723.88

So, rounded to the nearest foot, the cars are 7724 feet apart.

Given that your p-value (0.0202) is less than the significance level of 0.05, we would reject the null hypothesis at the 0.05 significance level. This suggests that the observed data provides sufficient evidence to conclude that there is a statistically significant effect or relationship, depending on the context of the test.

In statistical hypothesis testing, the p-value is used to determine the strength of evidence against the null hypothesis. The p-value represents the probability of obtaining a test statistic as extreme as the one observed, assuming the null hypothesis is true.

In your case, the p-value of the test is 0.0202. When comparing this p-value to the significance level (also known as the alpha level), which is typically set at 0.05 (or 5%), the conclusion can be drawn as follows:

If the p-value is less than or equal to the significance level (p ≤ α), we reject the null hypothesis.

If the p-value is greater than the significance level (p > α), we fail to reject the null hypothesis.

The correct answer is C: y = -3x - 3. This equation represents the line graphed above with a slope of -3 and a y-intercept of -3.

The equation that describes the line graphed above is option C: y = -3x - 3.

To determine the equation of a line, we need to use the slope-intercept form, which is y = mx + b, where m represents the slope of the line and b represents the y-intercept.

Looking at the line graphed above, we can determine the slope by comparing the change in y to the change in x. For every 1 unit increase in x, the line decreases by 3 units in the y-direction. Therefore, the slope is -3.

Next, we need to determine the y-intercept, which is the value of y when x is equal to 0. By looking at the graph, we can see that the line intersects the y-axis at y = -3.

Putting it all together, we have the equation y = -3x - 3. This equation represents a line with a slope of -3 and a y-intercept of -3.
