The answer is:
(x-5 - sq root 29) (x-5 + sq root 29)
Answer:
Step-by-step explanation:
The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. The empirical rule is further illustrated below
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations.
From the information given, the mean is 500 and the standard deviation is 100.
95% of the scores of students would fall within two standard deviations.
2 standard deviations = 2 × 100 = 200
500 - 200 = 300
500 + 200 = 700
Therefore, the probability that a randomly selected student math score is between 300 and 700 is
95%
Answer:
It is very useful because now, we use Diagrams and labels.
Step-by-step explanation:
we have
-----> equation A
-----> equation B
we know that
If the system has infinite number of solutions then, the equation A is equal to the equation B
so
isolate variable y in the equation B
Multiply by both sides
-------> new equation B
To find the value of b, equate equation A and equation B
therefore
<u>the answer is</u>
A4 * b4 * a4 * b4
make the 4s exponents in the same order
