The answer is B
Cause they all have the same angle points
To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.
For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.
Likewise for the other question it would be 270/15.
Answer:
10cm (I think)
Step-by-step explanation:
2/3 = .66666666 x 6 = 4
4 +6 = 10
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.
1. Find the Greatest Common Factor (GCF)
GCF=x
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
x(2x^4/x + 5x/x) <---Fraction inside parenthesis.
3. Simplify each term in parentheses.
Answer is x(2x^3+5)
I hope this helps.
