Step-by-step explanation:
A length of chain is to be constructed by placing 36 component links end to end. The length of a link produced by a production process is known to be a random variable with a mean of 2.5 cm with a standard deviation 0.2 cm. The 36 links are chosen at random from this process to produce the chain. The mean and standard deviation of the length of chain are, respectively _________.
a. 90 cm, 7.2 cm
b. 36 cm, 1.2 cm
c. 90 cm, 2.7 cm
d. 90 cm, 1.2 cm
e. 36 cm, 7.2 cm
Answer:
d. 90 cm, 1.2 cm
Step-by-step explanation:
Given that:
The sample size n = 36
For the length of the link:
The mean [tex]\overline x[/tex] = 2.5
The standard deviation s = 0.2 cm
In a chosen 36 links, The mean and standard deviation for the length chain is as follows:
Mean = n[tex]\overline x[/tex]
Mean = 36×2.5
Mean = 90 cm
The Standard deviation = s×√n
The Standard deviation = 0.2×√36
The Standard deviation = 0.2×6
The Standard deviation = 1.2 cm

Step-by-step explanation:
A dumpling machine automatically inserts mixed vegetables and meat filled wontons into a plastic package. Past experience revealed that some packages were underweight and some were overweight, but most of them had satisfactory weight.
Weight % of Total
Underweight 2.5
Satisfactory 90.0
Overweight 7.5
Required:
What is the probability of selecting two packages that are satisfactory?
a. 0.900
b. 0.729
c. 0.810
d. 0.075
Answer:
c. 0.810
Step-by-step explanation:
Given, total % of satisfactory packages = 90% = 0.90
Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)
Hence, Probability of selecting two packages that re satisfactory
P(Selecting 2 satisfactory packages) = (0.90)^2
P(Selecting 2 satisfactory packages) = 0.90*0.90
P(Selecting 2 satisfactory packages) = 0.810
Note: We are selecting product since the chance of selecting in each trials are independent.

Step-by-step explanation:
the virus is already 28% loaded if it is loaded at the rate of 12% every 10 minutes how much time do we have before it is 100% loaded .
Answer:
You will have 40 mins before 100%
Step-by-step explanation:
The number of minutes taken to completely load is 60 minutes.
Given that, the virus is already 28% loaded if it is loaded at the rate of 12% every 10 minutes.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here,
Remaining virus to load =100-28
= 72
The rate of 12% every 10 minutes
Now, 72/12
= 6
So, 6×10 =60 minutes
Therefore, the number of minutes taken to completely load is 60 minutes.

Find an equation of the line containing the given pair of points.
(−5,−5) and (4,4)
Answer:
y = x - 9
Step-by-step explanation:
[tex]Slope=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{4-(-5)}{4-(-5)}=\frac{9}{9}=1[/tex]
[tex]y-intercept:y-y_{1}=m(x-x_{1} ) \\y-(-5)=1(x-4)\\y+5=x-4\\[/tex]
Subtract 5 from both sides;
y = x - 9

Answer:
I say first one 7-pint jug of water for 3.22
Step-by-step explanation:
because 8 pints are in 1 gallon but there is 7 pints for 3.22 if do math correctly 8 pints would be 3.68 and that is one gallon right there so 2 gallons would only be 7.36 which is way cheaper than the second one being 2-gallon jug of water for 13.44.

1. Delia purchased a new car for $23,350. This make and model straight line depreciates to zero after 13 years.
a. Identify the coordinates of the x- and y- intercepts for the depreciation equation.
b. Determine the slope of the depreciation.
c. Write the straight-line depreciation equation that models this situation.
Answer:
a. y-intercept = 23350 and x-intercept = 13
b. [tex]m = -\frac{23350}{13}[/tex]
c. [tex]y = -\frac{23350}{13}x + 23350[/tex]
Step-by-step explanation:
Given
[tex]Years = 13[/tex]
[tex]Total\ depreciation = \$23350[/tex]
Solving (a): The x and y intercepts
The y intercept is the initial depreciation value
i.e. when x = 0
This value is the value of the car when it was initially purchased.
Hence, the y-intercept = 23350
The x intercept is the year it takes to finish depreciating
i.e. when y = 0
From the question, we understand that it takes 13 years for the car to totally get depreciated.
Hence, the x-intercept = 13
Solving (b): The slope
The slope (m) is the rate of depreciation per year
This is calculated by dividing the total depreciation by the duration.
So:
[tex]m = \frac{23350}{13}[/tex]
Because it is depreciation, it means the slope represents a deduction.
So,
[tex]m = -\frac{23350}{13}[/tex]
Solving (c): The straight line equation
The general format of an equation is:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
[tex]b = y\ intercept[/tex]
In (a), we have that:
[tex]y\ intercept = 23350[/tex]
In (b), we have that:
[tex]Slope\ (m) = -\frac{23350}{13}[/tex]
Substitute these values in [tex]y = mx + b[/tex]
[tex]y = -\frac{23350}{13}x + 23350[/tex]
Hence, the depreciation equation is: [tex]y = -\frac{23350}{13}x + 23350[/tex]

At the movies, Josh
purchase tickets at a rate of
5 for $25. He also wants to
buy one $10 snack pack.
If he needs to buy 8 tickets,
and only has $50, would he
have enough money to also
buy the snack pack?
Answer:
40 + 10 = 50
Step-by-step explanation:
Yes he does, if the tickets cost 5 for 25 that means that they cost $5 each. Josh needs 8 so he needs to multiply 8x5. The price for the tickets is $40. Since he wants to buy a snack pack for $10 he needs to add that to the $40. This makes exactly $50.
Hope this helps!
