The question is incomplete! The complete question along with answer and explanation is provided below.

Question:

In applying the Poisson probability distribution​ formula, ​P(x) equals  μx•e−μx!

Briefly describe what the symbol mu represents. Choose the correct answer below.A.The symbol mu is a variable that represents the area of each region.B.The symbol mu is a variable that represents the number of occurrences of the event in an interval.C.The symbol mu is a variable that represents the number of occurrences of the event.D.The symbol mu represents a static value.E.The symbol mu is a variable that represents the mean number of occurrences of the event in the intervals.

Answer:

μ is a variable that represents the mean number of occurrences of the event in the intervals.

Step-by-step explanation:

The Poisson distribution is often used to model the number of occurrences of an event in a certain interval.

P(x, μ)

Where the symbol mu (μ) represents the mean number of occurrences of an event x in a specified interval and the variable x represents a static value.

Therefore, the correct answer is option E, μ is a variable that represents the mean number of occurrences of the event in the intervals.

-7.66666, \sqrt(50,) -(157)/(20), -7.64 list these from least to greatest.
blagie [28]

Answer:

From least to greatest, the correct order is: -\frac{157}{20}; -7.666....; -7.64; and \sqrt{50}.

Step-by-step explanation:

Since \sqrt{50} is the only positive number, that means that it will be the greatest number on the list. -\frac{157}{20} is equivalent to -7.85, which makes it the smallest number. So you can conclude that the correct order is -\frac{157}{20}; -7.666...; -7.64; and \sqrt{50}.

Consider the integral 8 (x2+1) dx 0 (a) Estimate the area under the curve using a left-hand sum with n = 4. Is this sum an overe
Elina [12.6K]

Answer:

  (a) 120 square units, underestimate

  (b) 248 square units, overestimate

Step-by-step explanation:

(a) <u>left sum</u>

The left sum is the sum of the areas of the rectangles whose width is the total interval width (8-0) divided by the number of divisions (n=4). The height of each rectangle is the function value at its left edge.

We can compute the sum by adding the function values and multiplying that total by the width of the rectangles:

  left sum = (1 + 5 + 17 + 37)×2 = 60×2 = 120 . . . square units

The curve is increasing throughout the interval of interest, so the left sum underestimates the area under the curve.

__

(b) <u>right sum</u>

The rectangles whose area is the right sum are shown in the attachment, along with the table of function values. The right sum is computed the same way as the left sum, but using the function value on the right side of each subinterval.

  right sum = (5 + 17 + 37 + 65)×2 = 124×2 = 248 . . . square units

The curve is increasing throughout the interval of interest, so the right sum overestimates the area under the curve.

_____

The actual area under the curve on the interval [0, 8] is 178 2/3, just slightly less than the average of the left- and right- sums.

Peter saves $167 a month. Peter saves $37 less each month than Bill. How much will Bill save in 2 years?
Vlad [161]

Answer:

Hello! Your answer should be $2448.

Step-by-step explanation:

First, we should add 37 to 167 to find out how much money Bill makes in one month. Once we find that to be 204, we must multiply that by however many months he will be saving up for (24 months = 2 years). This will give us the expression 204 x 28, which equals 2448.

So, Bill will save $2448 in 2 years. Hope this helps!
