Brianna earned a total of approximately $400,652 over the 5 years.

A grouping of variables, symbols, and/or numbers used to represent a mathematical quantity or relationship is known as an expression in mathematics. Expressions might be straightforward with just one number or variable or complex with many terms, operations, and functions.

To find the total amount of money Brianna earned over 5 years, we need to calculate her salary for each of the 5 years and add them up.

In the first year, Brianna's salary was $77,000.

In the second year, her salary increased by 2%, so it became:

$77,000 + 0.02 x $77,000 = $78,540

In the third year, her salary increased by another 2%, so it became:

$78,540 + 0.02 x $78,540 = $80,106.80

In the fourth year, her salary increased by 2% again, so it became:

$80,106.80 + 0.02 x $80,106.80 = $81,700.94

In the fifth and final year, her salary increased by 2% once again, so it became:

$81,700.94 + 0.02 x $81,700.94 = $83,303.11

To find the total amount of money Brianna earned over the 5 years, we just need to add up her salaries from each year:

$77,000 + $78,540 + $80,106.80 + $81,700.94 + $83,303.11 = $400,651.85

Therefore, Brianna earned a total of approximately $400,652 over the 5 years.

The improper fraction is 45/8.

Answer:

45/8

Step-by-step explanation:

to get an improper fraction, you multiply the denominator by the whole number and add the numerator to the total. So for this problem 5(8)=40+5= 45/8

Answer:

Option c

Step-by-step explanation:

-7 + (19 + 5) = (-7 + 19) + 5

LHS = -7 + (19+5)

       = -7 + 24

       =  17

RHS = (-7 + 19) + 5

       = 12 + 5

        = 17

LHS = RHS

Step-by-step explanation: I think it is right but I don't know I am sorry if I get it wrong!

Step-by-step explanation:

=> p=1(l+b)

=> P = 1l + 1b

=> 1l - P = 1b

=> b = 1l - P/1

~Done~

Or

p=1(l+b)

Step 1: Flip the equation.

b+l=p

Step 2: Add -l to both sides.

b+l+−l=p+−l

b=−l+p

Answer:

b=−l+p

Answer:

B. Function A has a vertical asymptote at x = 1.

Function B has a vertical asymptote at x=−3.

Step-by-step explanation:

You can see from the diagram that the asymptope is x = -3, but to find the asymtope for the function make denominator equal to 0 and solve because the denominator can never equal 0, (you divide a number by 0, which is mathematically impossible) therefore the function will never reach that line.

Answer:

[tex]583 - 37 = 546[/tex]

Answer:

546

Step-by-step explanation:

subtract the numbers Frome each other

The line of best fit for the data of week and the corresponding miles run is evaluated to be: y = 4.699 + 1.671x

Firstly, there is a data set. Then, we try to fit a line which will tell about the linear trend. This line is made using the least squares method.

The following data for the Week and miles run variables are provided to construct linear regression model:

Week miles run

      1    5

      2    8

      4    13

     6    15

     8    19

    10    20

The independent variable is Week(represented by x), and the dependent variable is miles run(represented by y). In order to compute the regression coefficients, the following table needs to be used:

Let week = x, and miles run = y, then we get this table:

              x      y      xy    [tex]x^2[/tex]     [tex]y^2[/tex]

----------------------------------------------------

             1       5       5      1      25

             2      8       16    4     64

             4      13      52   16   169

             6     15       90   36  225

            8      19      152   64  361

           10     20     200  100 400

-----------------------------------------------------

Sum =  31   80    515   221  1244

Based on the above table, the following is calculated:

[tex]\bar X = \frac{1}{n} \sum_{i=1}^{n} X_i = \frac{ 31}{ 6} \approx 5.167[/tex]

[tex]\bar Y = \frac{1}{n} \sum_{i=1}^{n} Y_i = \frac{ 80}{ 6} \approx 13.33[/tex]

[tex]\large SS_{XX} = \sum_{i=1}^{n} X_i^2 - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} X_i\right)^2 = 221 - 31^2/6 \approx 60.833[/tex]

[tex]\large SS_{YY} = \sum_{i=1}^{n} Y_i^2 - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} Y_i\right)^2 = 1244 - 80^2/6 \approx 177.33[/tex]

[tex]\large SS_{XY} = \sum_{i=1}^{n} X_i Y_i - \displaystyle\frac{1}{n}\left(\sum_{i=1}^{n} X_i\right) \left(\sum_{i=1}^{n} Y_i\right) = 515 - 31 \times 80/6 \approx 101.67[/tex]

Therefore, based on the above calculations, the regression coefficients (the slope m, and the y-intercept n) are obtained as follows:

[tex]m = \frac{SS_{XY}}{SS_{XX}} \approx \frac{ 101.67}{ 60.833} \approx 1.6712[/tex]

[tex]n = \bar Y - \bar X \cdot m = 13.33- 5.167 \times 1.6712 = 4.6986[/tex]

Therefore, we find that the regression equation is:

miles run = 4.6986 + 1.6712 Week

y = 4.6986 + 1.6712x (approximately)

To the thousandths place, it becomes:

y = 4.699 + 1.671x

Therefore, based on the information provided above, the following scatter plot and regression plot are obtained as the image attached below.

Thus, the line of best fit for the data of week and the corresponding miles run is evaluated to be: y = 4.699 + 1.671x

How often do you recycle?

Step-by-step explanation:

Statistical questions are questions where results may vary meaning that depending on who you ask this question you can get very different but measurable answers.

Step-by-step explanation:

the formulas can be easily found on the internet.

remember, the diameter of a circle is 2 times the radius.

so, the radius of our circle here is 4/2 = 2 cm.

circumference :

2×pi×r = 2×3.14×2 = 12.56 cm

area :

pi×r² = 3.14×2² = 3.14×4 = 12.56 cm²

hey, your teacher gave you the circle, where the circumference and the area have the same quantity ! funny !

so, make double sure you use the correct unit dimensions (remember, a distance has only one dimension, an area has 2 dimensions, and a volume has 3 dimensions).

The distance between the points (3,4) and (-2,-1) is found being 5√2 units.

The shortest distance(length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

We've to find the distance between two points

(p,q) = (3,4)

and (x,y) = (-2, -1)

We get it as:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2}\\\\D = \sqrt{(-2-3)^2 + (-1-4)^2} \\\\D = \sqrt{5^2 + 5^2} = 5\sqrt{2} \: \rm units[/tex]

Thus, the distance between the points (3,4) and (-2,-1) is found being 5√2 units.

Answer:

36 sq in

Step-by-step explanation:

First find the area of the square: 12*12 = 144 in^2

next find the area of 1 circle, im assuming the circles are tangent to the sides of the square and to each other, so each circle has a radius of 12/4 or 3in, the area of each circle is then pi*3^2 or 27 in^2

the total area of the 4 circles is then 27*4 = 108in^2

144-108=36in^2
