3x4=12 gives him 12 baseballs. he has 5 fewer tennis balls than base balls so you subtract 5 from 12 and you get 7 tennis balls.
The best answer I believe is t - 2
You would cancel the common factors in the numerator and denominator.
Exact Form:
2/9
Decimal Form:
0.222222222.....
1) Call x the sample mean = 3.56
2) Call s the sample standard deviation = 0.2
3) Given that the variable is normally distributed and the sample is large, you determine the interval of confidence from:
x +/- Z(0.5) s/√n
Wehre Z(0.5) is the value of the probabilities over 5% (90% of confidence mean to subtract 10%, which is 5% for each side (tails) of the normal distribuition) and is taken from tables.
Z(0.5) = 0.3085
Then the inteval is
x +/- 0.385 *s /√n = 3.56 +/- 0.385 * 0.2/√45
3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.
Answer:
(2, 9)
Step-by-step explanation:
We've been given the exponential function;
f(x) = 25(3/5)^x
We need to determine the value of f(x) when x = 2, that is;
f(2) = 25(3/5)^2
Using a calculator we obtain
f(2) = 9
Thus the next point she plots on the graph will be (2, 9)
