Answer:
angle 2 = 22°
Step-by-step explanation:
When added together, angles 1 and 2 equal angle ABD.
Thus, angles 1 and 2 added together results in 109°.
Represent angle 1 as angle 2 plus 65°.
Our equation then becomes angle 2 + 65° + angle 2 = 109°.
Subtracting 65° from both sides, we get: 2·angle 2 = 44°.
Dividing both sides by 2 results in:
angle 2 = 22°
answer is 2.2 66 88862 u88272
Answer:
And using the normal standard distribution or excel we got:
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 weights of a population, and for this case we know the distribution for X is given by:
Where and
Since the dsitribution for x is normal then we know that the distribution for the sample mean is given by:
We want to find this probability:
And we can use the z score formula given by;
And if we find the z score for the limits given we got:
So we can calculate this probability like this:
And using the normal standard distribution or excel we got:
