The two different quantities to measure which school has higher academic performance are :

• Graduation rate / Budget per student

• SAT average / Budget per student

In other to define a quantity which measures academic achievement;

We take the ratio of a related metric or parameter which is a measure of the academic performance of the student in each school and the budget per student for each school .

The parameters which could be used to measure academic achievement are :

• The graduation rate of each school.

• The SAT average of each school.

Hence, defining the quantity to measure academic achievement relative to budget per student could be expressed as :

• Graduation rate / Budget per student

• SAT average / Budget per student

An example of a survey is A. Interviewing college students to find what percentage expects a job immediately after graduation.

A survey is defined as the collection of the data or o=interpretation of the data using a list of questions asked to a particular sample of a population which determines the whole population.

From the given options, we can clearly say that C and D are not an example of a survey since survey doesn't make use of the comparison process.

In both C and D, effectiveness of mouthwash and hair product are done by comparing two groups.

So it is not a survey.

In the case of cholesterol readings, only the elderly people is taken in to account.

So, the best option is A.

Hence the survey example is Interviewing college students to find what percentage expects a job immediately after graduation.

Answer:

UW = 36 units

Step-by-step explanation:

The question is incomplete. Here is the complete question

Point V lies between points U and W on Line segment U W. A line has points U, V, W. The length between U V is 2 x minus 4. The length between V W is 4 x + 10. If UW = 9x – 9, what is UW in units?

If a point V lies between points U and W on line segment UW, then based on vector notation, UV + VW = UW.

Given parameters

The length between U and V i.e UV = 2x-4

The length between V and W i.e VW= 4x + 10.

UW = 9x – 9

Required

The length between U and W in units

Since UW = UV+VW, we will substitute the given functions into the formula as shown;

9x-9 = 2x-4+4x + 10.

9x-9 = 2x+4x-4+10

9x-9 = 6x+6

collect like terms on both sides;

9x-6x = 6+9

3x = 15

x = 15/3

x = 5

Substitute x = 5 into the function UW = 9x-9 to ge the length of UW in units.

UW = 9(5)-9

UW = 45-9

UW = 36 units

Hence the required length between line segment U and W in units is 36units.

Answer and Step-by-step explanation:

H= {all numbers of the form 3n+1, for n natural number} under multiplication:

Sol: all number of the form 3n+1, for n natural number so, put n=2, 3(2) +1 = 7, which is a natural number. A natural number under multiplication does not form a group because its inverse does not exist.

J= {all number of the form 3n+2, for n natural number} under multiplication:

Sol: all the number of the form 3n+2, n is the natural number does not form a group under multiplication because the identity element does not form in this set, and inverse does not exist.

K= {perfect squares of integers} under addition:

Sol: perfect square of integers under addition does not form a group because the inverse does not exist. For example, for any element x, inverse (-x) does not exist because of a square integer.

L= {perfect squares of integers} under multiplication:

Sol: a set of the perfect square of integers under multiplication is not a set, because it does not have the inverse property

M= {all numbers of the form 2, for n natural number} under addition:

Sol: natural number in the form of 2n, n is a natural number under addition is not a group as it does not have identity property. Identity property, under addition, is zero.

N= {all number of the form 2n, n is natural number} under multiplication:

All number of the form 2n, n is the natural number under multiplication is not a group. Because its inverse does not exist. For example, an element x belongs to a natural number; its inverse (1/x) does not exist in this set.

Answer:

1, 1, 1, 2, 2, 2, 2, 3, 3, 3

Step-by-step explanation:

Since the standard deviation = 0

And the mean of the number = 2

If X is the sum of all the numbers, then

X/10 = 2

Cross multiply and make X the subject of formula

X = 2 × 10 = 20

The sum of the numbers will be 20

The number will be

1, 1, 1, 2, 2, 2, 2, 3, 3, 3

The sum of the above numbers is equal to 20 and the average value of the numbers is equal to 2.

Answer: 58

Step-by-step explanation:

From 10 AM to 1 PM the numbers are 161, 368, 842, and 1918

So now we find the difference between the numbers.

368 - 161 = 207

842 - 368 = 474

1918 - 842 = 1076

now it asked for the average so you add them together then divide by 3

which is (207+474+1076)/3 = 585.66666666....

Then it says to round to the nearest integer which is 586

Answer:

The correct answer is H. Independent variable.

Step-by-step explanation:

The independent variable, typically represented with the variable x, is the input of the function.  In an experiment, this is the variable that the scientist changes in order to see a change in the dependent variable.  The independent variable is usually plotted along the x-axis and its values represent the domain of the function.

The dependent variable, conversely, is typically represented with the variable y, and represents the output of the function.  In an experiment, the dependent variable would represent that change that occurs due to a change in the independent variable.  The dependent variable is usually plotted along the y-axis and its values represent the range of the function.

Answer:

The conditional form of this statement is false.

Step-by-step explanation:

Angles that are less than 90°, also known as right angle, are known as acute angles.

So, any angle that has a measure between 0° and 90° are known as acute angles.

The statement provided is:

"An angle with a measure of 88° is an acute angle."

The conditional form of this statement provided is:

"If an angle is an acute angle, then its measure is 88°."

This statement is false.

This is because an acute angle can measure between 0° and 90°.

It is not necessary that the measure of an acute angle is 88°.

Thus, the conditional form of this statement is false.

Answer:

this angle would be acute

Step-by-step explanation:

Answer:

6 markers

Step-by-step explanation:

5000/800 = 6.25

We can't have a quarter of a marker

If we were to round up it would have to be 5.6 km to fit 7 so we have to round down, and the answer is 6

In addition, along the 5000 m trail there will be one at 800, 1600, 2400, 3200, 4000, and 4800

We can only fit 6 of them along the trail if they are spaced 800 m apart so 6 markers will be able to fit on a 5k trail

Answer:

We need to calculate how many times there are 800 meters on 5000 meters.

To know so, we can divide 5000 by 800:

5000/800 = 6.25

So now, we know there are 800 meters 6.25 times on this trail.

So, how many markers have to be used? There have to be used 6, as the other 0.25 times will be the last 200 meters of the trail (800*0.25) and we only have to put a mark each 800.

We can also do this manually, from the start:

First mark would be at 800, next at 1600, next at 2400, next at 3200, next at 4000 and the last one at 4800. As we have said, 6 markers.

Answer:

By using the energy conservation law, the input energy must be equivalent to the output energy.  If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.

Thus, the energy not output by the machine is lost in the process within the machine.

Answer/Step-by-step explanation:

m<MAH = 90° (linear pair. It is also supplementary to m<MAK = 90°)

m<MAL + m<HAL = m<MAH

Which is:

(9x + 1) + (x + 9) = 90°

Solve for x

9x + 1 + x + 9 = 90

Collect like terms

9x + x + 1 + 9 = 90

10x + 10 = 90

Subtract both sides by 10

10x + 10 - 10 = 90 - 10

10x = 80

Divide both sides by 10

x = 8

Find m<MAL

m<MAL = 9x + 1

Plug in the value of x

m<MAL = 9(8) + 1 = 72 + 1 = 73°

Find m<HAL

m<HAL = x + 9

m<HAL = 8 + 9 = 17°
