Question 5). A Two way table, and Two way frequency table: is a way of displaying frequencies, or relative frequencies for two variables. (represented by rows, and columns).
Question 6). No Association/Association, is classified as perfect, strong, weak, or moderate.
Question 7). Negative association, and Positive association is one set of data values increases, and the other decreases.
Hope that helps!!!!
Answer:
f(x) = 1/2x + 6
Step-by-step explanation:
So before we even look at the first given formula, let's use the second formula: f(x) = -5.
Plug this formula into the x:
0 <= -5 <= 7
Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?
No, this is false.
So the formula, f(x) = -5, is not the graph of f.
That only leaves one possible option!
Answer:
A. 1,500m
B. 2000m
C. 1875m
Step-by-step explanation:
A. Here, we simply substitute the value of t in the equation.
t = 5min
V(t) = 400 - 20t
= 400 - 20(5)
= 400 - 100 = 300m/min
Now we know that distance = speed * time = 300 * 5 = 1,500m
2. Substitute t = 10
V = 400 - 20(10) = 400 - 200 = 200m/min
Distance = speed * time = 200 * 10 = 2000m
3. Here we need to calculate time
Rearranging the equation:
20t = 400 - V(t)
20t = 400 - 250
20t = 150
t = 150/20 = 7.5min
Distance traveled = 250 * 7.5 =1875m
Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b
