Step-by-step explanation:
It shows that the content of dietary fiber is negatively correlated to the blood cholesterol of college student, as the correlation coefficient is negative. However, the r=-0.45 shows the two factors are lowly correlated (absolute value of r between 0.3 and 0.5)
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40

Answer:
0.166
Step-by-step explanation:
Bought 18 cards for $2.99, so you can write it like this:
18 = 2.99
Since you want to find the value of one card, u could write that like this:
1 = x (where x is the unknown value of 1 card)
To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.
So 2.99/18 = 0.166
therefore x = 0.166
So you can say that each card costs about 17 c
