Answer:
a=-0.01
Step-by-step explanation:
Divide by -20 on both sides:
0.2/-20=-20a/-20
which will be:
-0.01=a
Answer: 1
Step-by-step explanation:
substitute x with 0 in the polynomial so we get,
-3^x
= -3^0
= 1 ( because any number raised to 0 is 1)
Hope it helps:)
In form ax + b = c: 2x - 8.4 = 5
Solution to equation: x = 6.7
Step-by-step explanation:
4x - 8.4 = 2x + 5
2x - 8.4 = 5
2x = 13.4
x = 6.7
60 000 plus 50 000 gives u the total amount
Answer:
False
Explanation:
A linear correlation coefficient is used to measure the the level of relationship between two seemingly dependent and independent variables. A relationship exists between two variables in linear correlation if one affects the other, either negatively or positively never zero. If linear correlation has a negative value then one variable increases while the other decreases. If linear correlation coefficient is positive then both variables increase together. If zero then there is no relationship as one variable's increase or decrease has nothing to do with the other. In the case above, correlation is positive at 0.08 hence we can say that there is a relationship between the two variables.
