Answer:
The answer is 11,337,408
Step-by-step explanation:
6^2 = 36, 3^2 = 9, 3^3 = 27, and 6^4 = 1296.
when you multiply them all together, you get 11,337,408.
Answer:
a) when x approaches negative infinity, A(x) approaches positive infinity and when x approaches infinity, A(x) approaches positive infinity
Step-by-step explanation:
there are 2 ways to figure this out:
1. when you multiply the factors together, you end up with . use the end behavior chart to figure out the end behavior.
look at the . the exponent is even and the coefficient is positive. therefore, the graph's end behavior goes towards infinity in both directions
2. graph problem and look at the end behavior
Answer:
In order to find the variance we need to find first the second moment given by:
And replacing we got:
The variance is calculated with this formula:
And the standard deviation is just the square root of the variance and we got:
Step-by-step explanation:
Previous concepts
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).
Solution to the problem
LEt X the random variable who represent the number of defective transistors. For this case we have the following probability distribution for X
X 0 1 2 3
P(X) 0.92 0.03 0.03 0.02
We can calculate the expected value with the following formula:
And replacing we got:
In order to find the variance we need to find first the second moment given by:
And replacing we got:
The variance is calculated with this formula:
And the standard deviation is just the square root of the variance and we got:
Answer: 900
Step-by-step explanation:
25 *9=225
225*4=900
Answer:
Prisms have two congruent — or identical — bases, and pyramids only have one base. The shape of the base on pyramids and prisms can vary, depending on the shape of the overall three-dimensional object. A prism has two identical bases that are parallel, while a pyramid has one base.
