Explanation

For the given data, we will have the following:

We are given grouped data, from which we will obtain the mean and standard deviation

Thus, we will have

From the above,

We have the mean to be approximately 44.68.

For the standard deviation

We will have

Thus, we have the standard deviation to be 10.22

Answer: 126°

Step-by-step explanation:

Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get

2x + 3x = 90°

5x = 90°

x = 18°

Plug in x for Angle 2, giving us Angle 2 = 54°

Angle 1 and angle 2 must add up to 180°

Subtract 54° from 180° and we get 126°

By definition, the Rate of change is also called "Slope".

The slope of a line can be found dividing the difference between the y-coordinates of two points, by the difference between the x-coordinate of those points:

In this case you know that:

Knowing the following point on the line:

You can set up the following (substituting the slope and the coordinates of those point into the formula)

Now you can solve for "a":

The answer is: Third option.

0. From the given graph, the cumulative frequency value indicates the number of students, we have 100 total number of students .

• so,Median is half of the students = 100/2 = 50

the value of test score that corresponds with 50 = 55 test score

• This means that the median , 50 students scored 55 % in the exa,m.

2. Finding the lower quartile Q1 :

since we have 100 students , 100/4 = 25, so Q1 = 25

the value that corresponds with cumulative frequency of 25 = 45

• This means that 25 students scores 45 %

3. Finding the Interquartile range :

IQR = Upper Quartile -Lower Quartile

Upper quartile = Q3 = 75 students : 60 %

and lower quartile = 45%

So,

IQR = 60-45

= 15

• This means that 15 students got 35 %

We will find the quotient and remainder as follows:

The quotient is 749 and the remainder is 2.

Step-by-step explanation:

We have to write the facts..

It's a little bit easy to understand if you put that numbers in a table.. like this

Now, they ask you an integer that represents a change per hour, and they say you that assume a constant change... then we complement the table with different values per hour until arrive at midnight..

now, you can see that you have two points.. with two coordinates, and you can find a line equation assuming that you have a constant change like this case...

that you place in the cartesian axes.. like this..

You know that you put x values in the horizontal line and y values in the vertical line..

for example, we're gonna place the point (2,1) that means that 2 in x axe and 1 in y axe..

Answer: 8 days

Step-by-step explanation:

1) Set up an equation. Let x be the day

3,500 >= 2(816) + x(100+95)

The 816 is just two times (Plane ticket back and forth) so it doesn't go into the x. 100 and 95 do as it is one day.

2) Solve the equation

3,500 >= 2(816) + x(100+95)

1868 >= 195x

9.57 >= x

3) Rounding

Since the x has to be less than 9.57, our next option is 8

Answer:

C 700

Step-by-step explanation:

7271 is close to 7000

12 is close to 10

So 7000/10 = 700

The given function is expressed as

y = (6x + 12)/2

In order to determine the inverse of the given function, we would substitute x for y and y for x. Then we would solve for y. It becomes

x = (6y + 12)/2

x = 3y + 6

3y = x - 6

y = (x - 6)/3

y = x/3 - 2

The inverse is

y = x/3 - 2

f(x)=x ^2

Translate 8.5 units to the left

f(x)= (x + 8.5 )^2

vertical Stretch of a factor of 3

f(x)= 3 (x + 8.5 )^2

7 units down

f(x)= 3 (x + 8.5 )^2 - 7

Step-by-step explanation:

your teacher is not very precise, I fear.

the yearly salary ($29,700) is the gross pay she gets.

the gross pay minus the taxes ($2,948 and $2,573) is then the net pay she receives.

in many cases the employer also withholds the health insurance premium (and then that has to be subtracted too before getting the net pay).

I just think your teacher means by "net pay" how much she will have left are all the monthly costs.

her annual net pay amount is

$29,700 - $2,948 - $2,573 = $24,179

the monthly net pay is $24,179/12 = $2,014.916666... ≈

please pick based on what you think your teacher means by net pay : the actual net pay by her employer, or how much money she has monthly left after paying all bills.

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

To find the equation for both 'm' and 'q' requires a bit of work. Because neither  'm' nor 'q' has two points to find the slopes of the line, we have to get creative.

The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.

For finding the slope of 'n'

The slope of the 'n'    =  (y₂ - y₁) ÷ (x₂ - x₁)      

=  (4 - (- 1)) ÷ (4 - 1)  

=  5 ÷ 3

=  ⁵/₃

To estimate the slope of 'q' and 'm'

When two lines exists parallel, they contain the exact slope.

Since 'n' and 'q' exists parallel,

then the slope of q = ⁵/₃

When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.  

Since 'n' and 'm' exists perpendicular

then the slope of m = - ³/₅

Write the equation for 'q' and 'm'

We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines

For both 'q' and 'm' let (x₁, y₁) be (2, 6)

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

Substitute 12 for t in eqn(1), we get

When t =24,

C(24) = 0 , ( does not exist since the graph did not touch the graph)

Hence, the correct answer are:

t =12, C(12) = 104 degrees Fehrenheit, and

t =24, C(24) = 32 degrees Fehrenheit

The linear equation parallel to y = 3x - 2 that passes through the point (4, 6) is:

y = 3*x - 6

Here we want to find a linear equation parallel to:

y = 3x - 2

Now, a general linear equation is:

y = m*x + b

Where m is the slope and b is the y-intercept.

Remember that two lines are parallel if and only if the lines have the same slope and different y-intercept.

So our linear equation will be something like:

y = 3*x + c

Now we also want our line to pass through the point (4, 6), then we can replace these values:

6 = 3*4 + c

6 = 12 + c

6 - 12 = c

-6 = c

So the linear equation is:

y = 3*x - 6

Jenny's age is 20 years, Lynn is 14 years and Kim is 23 years.

Let's take Jenny as J, Kim as K and, Lynn as L.

From the given statement we get the equation.

As the sum of the age of the three sisters is 57. So we have an equation,

J + K + L = 57 ........(i)

Jenny is 6 years older than Lynn. So the next equation is,

J = 6 + L .......(ii)

Kim is 5 years less than twice her age Lynn. So the equation is,

K = 2L -5 .........(iii)

Putting equations (ii) and (iii) in equation (i)

6 +L + 2L - 5 + L = 57

4L = 56

L = 14

Put the value of L in equations (ii) and (iii)

J = 6 + 14

 = 20

K = 2(14) -5

   = 28 - 5

   = 23

Therefore the age of Jenny is 20 years, Lynn is 14 years and Kim is 23 years.

102 students course earned C.

94 students course earned D.

53 students failed the course.

To find:-

How many degrees would be used to indicate the region A.

Total number of students is,

Now we find the degrees to indicate the region A. we get,

So the required soluion is 53.29 degrees.

whenever you have an equation with one variable on both sides, you might end up with one of the following case:

1. You might end up with an inconsistent equation, therefore there is not solution. Example

x = x+3. If you subtract x on both sides, you get 0=3 which is impossible.

2. You might end up having infinite solutions. Example:

x+6 = x+6. If you subtract x on both sides you get 6 =6 which is true regardless of the value of x.

3. You might end up having only one solution. Example:

3x +2 = x +5

If you subtract x on both sides and subtract 2 on both sides, you get

2x = 3.

then if you divide by two on both sides, you find

x = 3/2. So this equation has one unique solution.
