Answer:
Step-by-step explanation:
2x*2x=4x^2
2x*3=6x
Keep in mind 4x^2-6x
then next part:
3*2x=6x
3*3=9
6x-9
So totally
(4x^2-6x)-(6x-9)
Minus and minus is equal to +
(4x^2-12x+9)+2=45
4x^2-12x+11=45
-11 on both sides
4x^2-12x=34
X= -17/-2
Answer:
a) 8.2962
b) 6.3956
c) 3.845
Step-by-step explanation:
Z-score:
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

(a) What response represents the 85th percentile?
This is X when Z has a pvalue of 0.85. So X when Z = 1.037.




(b) What response represents the 62nd percentile?
This is X when Z has a pvalue of 0.62. So X when Z = 0.306.




(c) What response represents the first quartile?
The first quartile is the 100/4 = 25th percentile. So this is X when Z has a pvalue of 0.25, so X when Z = -0.675.




Answer: floating variable.

Answer(6,0)
Step-by-step explanation:
Answer:
there is no sequence
Step-by-step explanation:
The sequence is not geometric or arithmetic because there is no common difference or common ratio between each term.
Not a Geometric or Arithmetic Sequence
