If you're looking for x it is 5 which also makes YZ equal 5
I believe that the answer is a
Answer:
The no of elements in set A 'n(A)' = 35
Step-by-step explanation:
From the basic relation between two sets A and B we have
Since it is given that
Applying the given values in the above relation we get
Th area of a right triangle is A = 1/2 (ab), where a and b are the legs of the right angle. So area of the base is, A = 1/2 (9 x 12) = 108 cm2. With 2 bases, total area of base is 108 times 2, which is equal to 216 cm2. The other side of the triangular base nypotenuse) can be computed by Phythagorean theorem. Hypotenuse = square root of sum of the suare of 9 and 12. This is equal to 15 cm. There are other 3 rectangular faces with the following dimensions: 9 by 10 cm, 12 by 10 cm and 15 by 10 cm. Area of the other faces are 90, 120 and 150 cm2, by multiplying the length and width, only. Total area is 576 cm2.
The difference in the average age of the sample and the population is probably due to sampling error
<h3>What is sampling error?</h3>
The sampling error in a statistical data is simply an error that arises when a sample that represents the population is not properly selected or analyzed
From the question, we have the following parameters:
-- the sample average
-- the population average
Notice that:
i.e. sample and the population averages are not equal.
This difference is often as a result of sampling error
