Answer:
-11
Step-by-step explanation:
Find the slope using the formula [ y2-y1/x2-x1 ].
-9-(-12)/-15-(-24)
3/9
1/3
Find the y-intercept using the formula [ y = mx + b ].
y = 1/3x + b
-12 = 1/3(-24) + b
-12 = -8 + b
-4 = b
Use (18, 2) to see if the line passes through it
y = 1/3x - 4
2 = 1/3(18) - 4
2 = 6 - 4
2 = 2 TRUE
Thus, the line does pass through (18, 2).
Best of Luck!
Answer:
30
Step-by-step explanation:
Answer:
19
Step-by-step explanation:
1st you will use a^2+b^2=c^2
next you plug them in so it would be a^2+16^2=25^2
next you would solve it to a^2+256=625
then you would get 369 and square root it
and your answer will be 19.2.
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
