The graph of the Evan's data is attached below.
Dylan noted the time of day and the temperature, in degrees Fahrenheit, and his findings are as follows: At 6 a.m., the temperature was 58° F. For the next 3 hours, the temperature rose 1° per hour. For the next 4 hours, it rose 2° per hour. The temperature then stayed steady until 6 p.m. For the next 3 hours, the temperature dropped 2° per hour. The temperature then dropped steadily until the temperature was 62° at midnight. The data points are in the form of time and temperature. The data points are 6 AM = 58, 7 AM = 59, 8 AM = 60, 9 AM = 61, 10 AM = 63, 11 AM = 65, 12 PM = 67, 1 PM = 69, 6 PM = 69, 7 PM = 67, 8 PM = 65, 9 PM = 63, and 12 AM = 62.

Answer:
15 bracelets =$30 and 10 sets of earrings =$30
Step-by-step explanation:
30 +30=60
Distance = Speed × Time
Distance = (4.5 mi)/(0.75 h) × (3.5 h) = 21 mi
The walker will cover 21 miles in 3.5 hours at that pace.
Answer:
![\frac{3x}{ {(x + 1)}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%7D%7B%20%7B%28x%20%2B%201%29%7D%5E%7B2%7D%20%7D%20)
Step-by-step explanation:
![(\frac{3x}{x + 1}) \div (x + 1) \\ \\ = \frac{ \frac{3x}{x + 1} }{x + 1} \\ = \frac{ \frac{3x}{x + 1} }{ \frac{x + 1}{1} } \\ = \frac{3x \times 1}{(x + 1) \times (x + 1)} \\ = \frac{3x}{ {(x + 1)}^{2} }](https://tex.z-dn.net/?f=%20%28%5Cfrac%7B3x%7D%7Bx%20%2B%201%7D%29%20%20%5Cdiv%20%28x%20%2B%201%29%20%5C%5C%20%20%20%5C%5C%20%20%3D%20%20%20%5Cfrac%7B%20%5Cfrac%7B3x%7D%7Bx%20%2B%201%7D%20%7D%7Bx%20%2B%201%7D%20%5C%5C%20%20%20%3D%20%20%5Cfrac%7B%20%5Cfrac%7B3x%7D%7Bx%20%2B%201%7D%20%7D%7B%20%5Cfrac%7Bx%20%2B%201%7D%7B1%7D%20%7D%20%20%5C%5C%20%3D%20%20%20%5Cfrac%7B3x%20%5Ctimes%201%7D%7B%28x%20%2B%201%29%20%5Ctimes%20%28x%20%2B%201%29%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B3x%7D%7B%20%7B%28x%20%2B%201%29%7D%5E%7B2%7D%20%7D%20)
Answer:
The Geometric Mean of 4 and 12 is 6.9
Step-by-step explanation:
Given Numbers are 4 and 12
To find : Geometric mean of the given No.
The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.
Formula for Geometric Mean is given by,
![Geometric\,Mean\,of\,x_1\,,\,x_2\,,\,x_3..x_n=\sqrt[n]{x_1\times x_2\times x_3\times\,...\,\times x_n}](https://tex.z-dn.net/?f=Geometric%5C%2CMean%5C%2Cof%5C%2Cx_1%5C%2C%2C%5C%2Cx_2%5C%2C%2C%5C%2Cx_3..x_n%3D%5Csqrt%5Bn%5D%7Bx_1%5Ctimes%20x_2%5Ctimes%20x_3%5Ctimes%5C%2C...%5C%2C%5Ctimes%20x_n%7D)
⇒ Geometric Mean of 4 and 12 = ![\sqrt{4\times12}](https://tex.z-dn.net/?f=%5Csqrt%7B4%5Ctimes12%7D)
= ![\sqrt{48}](https://tex.z-dn.net/?f=%5Csqrt%7B48%7D)
= ![4\sqrt{3}](https://tex.z-dn.net/?f=4%5Csqrt%7B3%7D)
= 6.92820323028
= 6.9
Therefore, The Geometric Mean of 4 and 12 is 6.9
