Answer:
10
Explanation:
The distance between two points of coordinates (x1, y1) and (x2, y2) can be calculated as:
![\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
So, the distance between (-2, 5) and (8, 5) is equal to:
![\begin{gathered} \sqrt[]{(8-(-2))^2+(5-5)^2} \\ \sqrt[]{(8+2)^2+(0_{})^2} \\ \sqrt[]{(10)^2+0} \\ \sqrt[]{100} \\ 10 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%5B%5D%7B%288-%28-2%29%29%5E2%2B%285-5%29%5E2%7D%20%5C%5C%20%5Csqrt%5B%5D%7B%288%2B2%29%5E2%2B%280_%7B%7D%29%5E2%7D%20%5C%5C%20%5Csqrt%5B%5D%7B%2810%29%5E2%2B0%7D%20%5C%5C%20%5Csqrt%5B%5D%7B100%7D%20%5C%5C%2010%20%5Cend%7Bgathered%7D)
Then, the distance between (-2, 5) and (8, 5) is 10.
Answer:
0.43
Step-by-step explanation:
To calculate the relative frequency of any of the values in the frequency table, divide the value by the total (120)
For example, the relative frequency of boys who prefer math is:
43 ÷ 120 = 0.36
Reading from the frequency table, the total number of boys is 52. Therefore, the relative frequency for the total number of boys is:
52 ÷ 120 = 0.43

I am a student. Jake should receive 8.15 dollars in change. Please pick me brainliest! I am new to this website and I wanna help.
Step-by-step explanation:
Answer:
The answer would be "because 4 + (negative 7) is an equivalent expression, the answer is –3".
Step-by-step explanation:
First of all, determine if the answer is going to be positive or negative by seeing the sign of the greater number (that would be 7). So, the answer would be negative. Then do the expression using absolute values; 7-4=3. Now, just add the negative sign before 3 and that's it. You did it! Please rank Brainliest if this helps. Thank you!
