Answer:

It's around 459. So 460 if need to round

Step-by-step explanation:

So, 40 randomly chosen people do not represent  the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)

The function call "calcNet(emp)" passes a copy of the complete emp structure to calcNet(). This is because "emp" refers to the variable name of the structure, and passing it without the "&" operator or the "*" operator means that a copy of the structure is passed instead of a reference or a pointer.

In this case, calcNet() would receive a complete copy of the emp structure and be able to perform calculations on it. However, any changes made to the structure within calcNet() would not be reflected in the original emp structure.
It is important to understand the difference between passing by value (copying the data) and passing by reference or pointer (passing a reference to the data). Passing by reference or pointer allows for changes made to the data within a function to be reflected in the original variable outside of the function.
In summary, the correct answer to the question is b) calcNet(emp), which passes a copy of the complete emp structure to calcNet().

The complete question is:-

the function call ____ passes a copy of the complete emp structure to calcnet().

a) calcNet(struct emp);

b) calcNet(emp);

c) calcNet(&emp);

d) calcNet(*emp)

Answer: The greatest number of students for whom 30 apples, 45 pears and 60 oranges can be distributed equally is 15.

Step-by-step explanation:

taking HCF

so

HCF of 30,45,60

30 = 2*5*3

45 = 3*3*5

60=3*2*2*5

HCF = 3*5 = 15

so

1 student will get = 30/15 = 2 apples

1 student will get = 45/15 = 3 pears

1 student will get = 60/15 = 4 oranges

There are 1,430 ways to choose 20 doughnuts from 5 different flavors with the given restrictions.

The solution to this problem can be found using the inclusion-exclusion principle.

(1) The universe set X: The total number of ways to choose 20 doughnuts from 5 different flavors without any restrictions. This can be calculated using the formula for combinations with repetition, which is (n+r-1) choose r, where n is the number of flavors and r is the number of doughnuts. In this case,

X = (5+20-1) choose 20 = 24 choose 20 = 10,626.

(2) The excluded subsets Ai: These are the sets of choices that include more than 5 of each of the first three flavors. There are three excluded subsets, one for each of the first three flavors.

(3) The method used to count the intersections of excluded subsets: We can use the inclusion-exclusion principle to count the number of ways to choose 20 doughnuts with the restrictions. The formula is

|X| - |A1| - |A2| - |A3| + |A1 ∩ A2| + |A1 ∩ A3| + |A2 ∩ A3| - |A1 ∩ A2 ∩ A3|.

To calculate each of the excluded subsets and their intersections, we can use the same formula for combinations with repetition, but with different values for n and r. For example, |A1| is the number of ways to choose 20 doughnuts with more than 5 of the first flavor, which is the same as choosing 15 doughnuts from 5 flavors without restrictions.

So |A1| = (5+15-1) choose 15 = 19 choose 15 = 3,876.

Using the same method, we can calculate |A2| = 3,876, |A3| = 3,876, |A1 ∩ A2| = 1,287, |A1 ∩ A3| = 1,287, |A2 ∩ A3| = 1,287, and |A1 ∩ A2 ∩ A3| = 429.

Plugging these values into the inclusion-exclusion formula, we get:

|X| - |A1| - |A2| - |A3| + |A1 ∩ A2| + |A1 ∩ A3| + |A2 ∩ A3| - |A1 ∩ A2 ∩ A3| = 10,626 - 3,876 - 3,876 - 3,876 + 1,287 + 1,287 + 1,287 - 429 = 1,430

So the answer is 1,430 ways to choose 20 doughnuts from 5 different flavors with the given restrictions.

Step-by-step explanation:

You just uhh explained the pythagorean theorem formula

\(a^{2} + b^{2} = c^{2}\)

but what's the question?

There are 5 erasers to accompany the 20 pencils based on the given ratio.

If the ratio of pencils to erasers is 4:1, and there are 20 pencils, we can determine the number of erasers by setting up a proportion.

The proportion can be written as:

pencils/erasers = 4/1

Given that there are 20 pencils, we can substitute this value into the proportion:

20/erasers = 4/1

To solve for erasers, we can cross-multiply:

\(20*1=4*erasers\)

\(20 = 4*eraser\)

Since there is only 1 unit assigned to erasers, we multiply the unit value (5) by the number of eraser units (1) to find the total number of erasers, which is 5.

Dividing both sides by 4:

20/4 = erasers

5 = erasers

Therefore, there are 5 erasers.

Answer:

Reflection

Step-by-step explanation:

With a reflection, a shape is mirrored across a line. So, while its position is changed, the points end up getting flipped too. In this problem, you can imagine a diagonal line goes right through the center of the two shapes shown (the original and its mirror). The line would be equidistant from L and G; it would be equidistant from B and D; it would also be equidistant from U and O. If you were to mirror B, U, and L across this line, you would get your reflection points D, O, and G.

The shape BUL is mirrored over a diagonal line to get DOG, which means it is a reflection

Answer:

Step-by-step explanation:

First let us get the slope of the line PQ and RS

For PQ;

Given P(6, -2) and Q(-2,8)

slope m = 8-(-2)/-2-6

slope of pQ = 10/-8

slope of PQ = -5/4

For RS

R ( − 4 , 3 ) and S(-9, y)

slope of RS = y-3/-9+4

slope of RS = y-3/-5

For PQ to be perpendicular to RS, the product of their slope must be -1

Hence -5/4 (y-3/-5) = -1

y-3/4 = -1

cross multiply

y-3 = -4

y = -4+3

y = -1

Hence the value of y for PQ to be perpendicular to RS is -1

The probability of adding either ground beef or onion as the first ingredient  0.25 or 25%.

If there are a total of 8 ingredients and 2 of them are either ground beef or onion, then the probability would be:

Probability = (Number of desired outcomes) / (Total number of possible outcomes)

           = 2 / 8

           = 1 / 4

           = 0.25

So, the probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%.

In this case, we have a total of 8 ingredients, out of which 2 are either ground beef or onion. When selecting the first ingredient, there are 8 possible outcomes. Since we want to calculate the probability of adding either ground beef or onion as the first ingredient, we count the number of desired outcomes, which is 2 (either ground beef or onion). Dividing the number of desired outcomes by the total number of possible outcomes gives us the probability.

The probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%. This means that there is a 25% chance that either ground beef or onion will be the first ingredient added, assuming the ingredients are added randomly without any specific order.

Step-by-step explanation:

z_1 and z_2 are complex number;

i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))

ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))

To calculate z₁z₂ and z₁/z₂, we need to perform the complex number operations on z₁ and z₂. Let's break down the calculations step by step:

i) To find z₁z₂, we multiply the magnitudes and add the angles:

z₁z₂ = 4cos(cos(π/4) + isin(π/4)) * 2cos(2π/3) + isin(2π/3))

= 8cos((cos(π/4) + 2π/3) + isin((π/4) + 2π/3))

= 8cos(7π/12) + isin(7π/12)

ii) To find z₁/z₂, we divide the magnitudes and subtract the angles:

z₁/z₂ = (4cos(cos(π/4) + isin(π/4))) / (2cos(2π/3) + isin(2π/3))

= (4cos((cos(π/4) - 2π/3) + isin((π/4) - 2π/3))) / 2

= 2cos(π/12) + isin(π/12)

i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))

ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))

The location of √ 7 on a number line between 2 and 3.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every number line point is considered to correspond to a real number and every real number to a number line point.

A number line is a long straight line with numbers marked at equal intervals. On a number line, we can argue that as we move to the right, the value of numbers increases. This signifies that the numbers on the right are more than those on the left.

A number line shows how numbers are related. It's a line with check marks next to each number. The numerals get smaller as you move left on the number line. The numbers grow larger as you move closer to the number line.

In this case, ✓7 is 2.65. This number can be found between 2 and 3. This should be the true statement since the options aren't given.

The depth of the water is changing at a rate of approximately 0.39 m/s when the radius of the top of the water is 10 meters.

To find the rate at which the depth of the water is changing, we can use related rates.

Given:
Height of the cone (h) = 8 meters
Base radius (r) = 26 meters
Rate of filling (dV/dt) = 12 m³/s
Radius of the top of the water (x) = 10 meters

First, we establish the relationship between the height and radius of the cone using similar triangles. The ratio of the height to the radius is constant, so we have h/r = 8/26.

Next, we differentiate both sides of the equation with respect to time (t) to find dh/dt in terms of dx/dt. This gives us (dh/dt)/(dr/dt) = 0.3077.

We can then substitute the given values into the equation: (dh/dt)/(dx/dt) = 0.3077. Rearranging the equation, we find that dx/dt = (dh/dt) / 0.3077.

To find the value of dh/dt, we can substitute the given rate of filling, dV/dt = 12 m³/s, into the equation. Solving for dh/dt, we get dh/dt = 3.693 m/s.

Finally, we substitute the values of dh/dt and 0.3077 into the equation to find dx/dt. This gives us dx/dt ≈ 0.39 m/s.

Therefore, the depth of the water is changing at a rate of approximately 0.39 m/s when the radius of the top of the water is 10 meters.

Step-by-step explanation:

There are a few equations that can be used for this, but the simplest one would be y = mx + b

We are given:

y = -3

m = -3/5 (slope)

x = -5

b = ?

Our equation is this, we are solving for b

==> -3 = -3/5 ( -5) + b

==> -3 = -3/5 ( -5) + b ( multiply the brackets)

==> -3 = 3 + b ( subtract 3 to both sides)

==> -6 = b

Now we can make the desired equation in slope intercept form;

y = -3/5x - 6
