Answer:

36

Step-by-step explanation:

N = 6

S = 0 n = 1

2(1) - 1 = 1

S = 0 + 1 = 1

n = n + 1

n = 1 + 1

n = 2

S = 1 n = 2

2(2) - 1 = 3

S = 1 + 3 = 4

n = n + 1

n = 2 + 1

n = 3

S = 4 n = 3

2(3) - 1 = 5

S = 4 + 5 = 9

n = n + 1

n = 3 + 1

n = 4

S = 9 n = 4

2(4) - 1 = 7

S = 9 + 7 = 16

n = n + 1

n = 4 + 1

n = 5

S = 16 n = 5

2(5) - 1 = 9

S = 16 + 9 = 25

n = n + 1

n = 5 + 1

n = 6

S = 25 n = 6

2(6) - 1 = 11

S = 25 + 11 = 36

n = n + 1

n = 6 + 1

n = 7 > N

Rita is starting a running program. the table shows the total number of miles she runs in different weeks. what is the equation
Stolb23 [73]

Based on the table, the equation of the line of best fit to the nearest thousandths is equal to y = 1.671x + 4.699.

<h3>How to determine the equation of the line of best fit?</h3>

Mathematically, the equation of the line of best fit is calculated by using this formula:

y = mx + c

<u>Where:</u>

  • m is the slope.
  • c is the intercept.

Based on the table, the slope and intercept to the nearest thousandths are equal to 1.671 and 4.699 respectively.

Therefore, the equation of the line of best fit is equal to y = 1.671x + 4.699.

mojhsa [17]

Answer:

about 16°

Step-by-step explanation:

Make sure your calculator is in degree mode.

Drawing the right triangle, we see that the shorter leg is 34 meters, and the longer leg is 122 meters. So the angle of elevation is:

\tan( \alpha )  =  \frac{34}{122}

\alpha  =  { \tan }^{ - 1}  \frac{34}{122}  = 15.57
