he FDAL level for insect filth in chocolate is 0.6 insect fragments (larvae, eggs, body parts, and so on) per grams. Suppose that there is an average of 0.57 insect fragments per gram of chocolate bar and the distribution is following a Poisson distribution. Compute the probabilities that the number of insect fragments in a 50-gram sample of chocolate bar are:
Answer:
Step-by-step explanation:
[tex]\text{To find :} \\ \\ 1.) \ \ \text{More than 20} \\ \\ 2) \text{Less than 30 } \\ \\ 3) \ \text{Within the range of }( \mu - \sigma , \mu +\sigma)[/tex]
[tex]\ \ \ Since \ \ X \ \text{follows a poisson distribution and;} \\ \\ X\sim Poisson (0.57) per \ gram \\ \\ X \sim Poisson (28.5) \ per \ 50 \ grams \\ \\[/tex]
[tex]1) \ \ \ \text{The probability } P(X>20) = \sum \limits ^{50}_{x=21} \dfrac{e^{-28.5}\times 28.5^x}{x!} \\ \\ \mathbf{ = 0.9389}[/tex]
[tex]2) P( X<30) = \sum \limits ^{29}_{x=0} \dfrac{e^{-28.5}\times 28.5^x}{x!} \\ \\ \mathbf{=0.5861}[/tex]
[tex]\text{3) Since then mean}\ \mu = 28.5 \\ \\ \sigma =\sqrt{28.5} = 5.339 \\ \\ \mu - \sigma = 28.5 -5.339= 23.161 \\ \\ \mu + \sigma = 28.5 + 5.339 = 33.839[/tex]
∴
[tex]P(23.161 < X< 33.839) = \sum \limits ^{33}_{24} \dfrac{e^{-28.5}\times 28.5^x}{x! } \\ \\ = P(X\le 33) - P( X \le 23) \\ \\ = 0.82678 - 0.1750 \\ \\ \mathbf{= 0.6516}[/tex]
Math. Find Mid point and fx
Answer: Option B.
Step-by-step explanation:
When we have an interval with lower bound m and upper bound M, such that:
m ≤ x ≤ M
The mid-point is:
(m + M)/2
in this case, we have:
m = 22
M = 27
then the mid-point is:
(22 + 27)/2 = 24.5
and we know that f = 7, then:
f*x = f times the mid-point = 7*24.5 = 171.5
The correct option is B.

Find the area of the figure. Use 3.14 for A. N 8 m 12 m
Answer: 105m²
Formula for Area of Circle: A = π r²
so, A = 3.14 (6)² (I got 6 because radius is half the diameter)
Don't forget to divide the final area of the circle in half, because It's only a semicircle.
Formula for Triangle: A = [tex]\frac{bh}{2\\}[/tex]
so, A = [tex]\frac{6(8)}{2}[/tex] (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)
You need to multiply the final area of the triangle by 2 since there are 2 triangles.

Find sec x if sin x = -7/25 and cot x = -24/7.
Show work. Thanks.
Answer:
[tex]sec\ x = \frac{25}{24}[/tex]
Step-by-step explanation:
Given
[tex]sin\ x = -\frac{7}{25}[/tex]
[tex]cot\ x = -\frac{24}{7}[/tex]
Required
Determine sec x
Sec x is calculated as:
[tex]sec\ x = \frac{1}{cos\ x}[/tex]
Multiply by sin x/sin x
[tex]sec\ x = \frac{1}{cos\ x} * \frac{sin\ x}{sin\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \frac{sin\ x}{cos\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \tan\ x[/tex]
[tex]tan\ x = \frac{1}{cot\ x}[/tex]
[tex]sec\ x = \frac{1}{sin\ x} * \frac{1}{cot\ x}[/tex]
The equation becomes:
[tex]sec\ x = \frac{1}{-7/25} * \frac{1}{-24/7}[/tex]
[tex]sec\ x = \frac{-25}{7} * \frac{-7}{24}[/tex]
[tex]sec\ x = \frac{25}{24}[/tex]

What is the mean, median and mode of the data below. (List in that order: mean, median, mode) 18, 24, 20, 18, 21
Answer:
Mean: [tex]20.2[/tex], Median: [tex]20[/tex], Mode: [tex]18[/tex]
Step-by-step explanation:
The mean or average of a data set is calculating by dividing the sum of the data values by the number of the data values. In this case, the sum of the data values is [tex]18+24+20+18+21=101[/tex] and the number of data values is [tex]5[/tex], so the mean is [tex]\frac{101}{5}=20.2[/tex].
The median of a data set is the middle value when the data is ordered in ascending order, meaning least to greatest. Right now, the data is not in ascending order, but after ordering it, we get [tex]18,18,20,21,24[/tex]. Since there are [tex]5[/tex] data values in this set, the middle value, or median, will be the [tex]3[/tex]rd value, which, in this case, is [tex]20[/tex].
Finally, the mode of a data set is the most frequent value, or the value that shows up the most. In this case, [tex]18[/tex] shows up twice, unlike the other numbers, which only show up once, so we know that the mode is [tex]18[/tex]. Hope this helps!
A system of equations is shown below.
X + 7y = 23
3x + 14y = 48
What is the value of x + y in the solution to the system?
Answer:
A
Step-by-step explanation:
The value of x + y for the given system of equations is found to be as 5.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
The given equations are as follows,
x + 7y = 23 (1)
3x + 14y = 48 (2)
Solve the equations by substituting the value of x from equation (1) into (2) as follows,
3x + 14y = 48
=> 3(23 - 7y) + 14y = 48
=> -21y + 14y = 48 - 69
=> -7y = -21
=> y = 3
Then, x = 23 - 7y = 23 - 7 × 3 = 2
Thus, the value of x + y is given as 3 + 2 = 5.
Hence, the value of the required expression is given as 5.
