Answer:
3
Step-by-step explanation:
For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c
Where m represents the slope and c represents the y intercept
Now let’s take the last point on the table;
and substitute the values of x and y;
we have;
10 = 2m + c. ••••••••(i)
let’s take the second to the last;
7 = m + c ••••••••••(ii)
So let’s solve both equations simultaneously
Just subtract second from first directly
This gives m = 3
Answer: 14s - 7s/2 = 84
Step-by-step explanation:
Given that s is the length of the unknown side:
Area of the shaded region = 84
Area of rectangle - Area of triangle = 84
Area of rectangle = L * W
= 14 * s
= 14s
Area of triangle = ¹/₂ * base * height
= ¹/₂ * 14 * s/2
= 7s/2
Area of shaded region:
14s - 7s/2 = 84
Solving for s:
14s - 7s/2 = 84
28s - 7s = 168
21s = 168
s = 168/21
s = 8 inches
It's d) 23 would be the answer
Answer: D) At the next school assembly, choose one student from each of 20 randomly selected rows.
Step-by-step explanation:
A wouldnt be correct because it is all students from the spots program
B isnt correct because it is 10 girls and 10 boys from the girls' and boys' soccer teams
C wouldnt be correct because it would be the first 20 students she sees once she leaves statistics class
D is the only unbiased, completely random selection choice.
