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.

[tex]16^1[/tex]=16

Answer:

im not sure but i think this is the answer

Step-by-step explanation:

I think it would be 130 + 0.75m

Which simplified could be 130.75m Hope it helps! :)

0.75m - 20

[tex]130+0.75\left(m-200\right)\ =\ 0.75m-20[/tex]

[tex]0.75(m-200) + 130[/tex]

The slope is 0.75

Substitute m for 0 ( [tex]0.75(-200) + 130[/tex])

Evaluate the equation ( [tex]0.75(-200) + 130[/tex]) = -20, this is the y-intercept

now the equation is [tex]slope + intercept[/tex] = [tex]0.75 -20[/tex]

The surface area of the solid shape is the amount of space on it

The radius of the two cones is 2.93 cm

The given parameters are:

The surface area of the shape is calculated using:

T = πr(L + l)

So, we have:

135.21 = πr(2r + 3r)

Evaluate

135.21 = 5πr²

Divide both sides by 5π

r² = 135.21/5π

Evaluate the quotient

r² = 8.61

Take the square root of both sides

r = 2.93

Hence, the radius of the cones is 2.93 cm

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

Answer:

4.699

Step-by-step explanation:

The graph that shows the proportional relationship y = 0.7x is Graph A.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, 7 out of 10 customers preferred the restaurants new spaghetti sauce, hence the constant is given by:

k = 7/10 = 0.7.

And the equation is:

y = 0.7x.

When x = 0, y = 0, which already eliminates graphs C and D. When x = 10, y = 7, which means that Graph A is the answer to this question.

Given:

Circumference

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

Answer:

the radius of circle s is point,radius,arc,

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).
