The answer is it is a statistic because the value describes a characteristic of a sample.
Answer:
3x = 1.5x + 8.4
8.4/1.5=5.6
5.6 x 3 = 16.8
5.6 x 1.5 + 8.4 = 16.8
Step 1. Cancel out the -0.4 so you add 0.4 to both sides
Step 2. Divide 8.4 by 1.5 = 5.6
Step 3. Replace X with 5.6 and check if the equation is correct
5.6 is the answer

Answer:
#1 4) 15 boys to 40 girls #2 1) 1, 3, 4, 6 #3 1) 3/5
Step-by-step explanation:
#1 3:8 Multiply both sides of this ratio by 5 15:40
#2 1, 3, 4, 6 These statements are all true.
#3 9/15 Divide both numbers by 3 3/5
The answer correct is C.
We can use the linear equation y=mx+b to help. y is the dependent variable, m is slope, x is the independent variable, and b is the y intercept.
In this case, the values of x and y were not given, so we still have y=mx+b. We can substitute 9/4 for m and -14 for b to get y=9/4x-15, which is C.
C is correct. (1,-5)
-5 - 3(1) =
-5 + - 3 = -8
