Answer:
G=(T²+N²)/4
Step-by-step explanation:
(√4G-N²)²=T²
4G-N²=T²
4G=T²+N²
G=(T²+N²)/4

Answer:
1.
2.
3.
4.
Step-by-step explanation:
1. For the equation , subtract 13.5 from both sides of the equation:
And divide both sides by 5:
2. For the equation , subtract 16 from both sides of the equation:
And divide both sides by -14:
3. For the equation , add 18 to both sides of the equation:
And divide both sides by -32:
4. For the equation subtract 4 from both sides of the equation:
And multiply both sides by 5:
Answer:
The answer is The number 5
Step-by-step explanation:
-5 is an integer and a rational number but not a whole number
3.5 and ½ are rational numbers they are neither whole numbers nor integers
5 is a whole number an integer and a rational number
Answer:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with the normal standard distribution table:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with the normal standard distribution table:
