Answer:
The value is [tex]UCL = 10.8[/tex]
Step-by-step explanation:
From the question we are told that
The sample mean is [tex]\= x = 9 \ ounce[/tex]
The sample size is n = 25
The standard deviation is [tex]\sigma = 3 \ ounce[/tex]
Given that the sample size is not large enough i.e n< 30 we will make use of the student t distribution table
From the question we are told the confidence level is 99.7% , hence the level of significance is
[tex]\alpha = (100 -99.7 ) \%[/tex]
=> [tex]\alpha = 0.003[/tex]
Generally the degree of freedom is [tex]df = n- 1[/tex]
=> [tex]df = 25 - 1[/tex]
=> [tex]df = 24[/tex]
Generally from the student t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 24[/tex] is
[tex]t_{\frac{\alpha }{2} , 24 } = 3.0 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2} , 24} * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 3.0 * \frac{3 }{\sqrt{25} }[/tex]
=> [tex]E =1.8 [/tex]
Gnerally the upper control chart limit for 99.7% confidence is mathematically represented as
[tex]UCL = \= x + E[/tex]
=> [tex]UCL = 9 + 1.8[/tex]
=> [tex]UCL = 10.8[/tex]

Answer:
A function maintains a constant slope and shows no irregularities such at x1= 10 and y2= -100 and then x2= -90 and y2= 900Hence WDominic is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The total cost of the gym membership over t months is given by the equation C=45t+100. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
The slope intercept form is y=mx+b, and b represents the y-intercept. In the given equation C=45t+100, 100 is the y-intercept. It represents the one-time fee to join the gym membership.
Answer:
y intercept is 100
which represents the one-time joining fee

Answer:
You have to divide 46 by 6. thats all I know sorry
Step-by-step explanation:
Each student gets 7 pencils.
What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Here, it is given that :
Mr. Rodriguez purchased 46 pencils to give to the students he tutors
and number of students = 6
Therefore, to find number of pencils each student get we divide 46 with 6 :
pencils will each student get = 46/6
pencils will each student get ≈ 7
as each student get equal number of pencils then 4 pencils are left with Mr. Rodriguez after giving 42 pencils to the students.
Therefore, each student gets 7 pencils.

A full 335 ml can of Coca-Cola is filtered at a rate
of 5 ml per minute into an empty can. How long
will it take for the two cans to have the same
amount, a, of Coca-Cola?
Mm
9514 1404 393
Answer:
33.5 minutes
Step-by-step explanation:
There are many ways you can look at this problem. One is to write equations for the amount in each can, and solve for the time that makes those amounts equal. Another is to consider how much time it takes to reduce the volume by half.
Using the first method, we have ...
335 -5t = 5t
335 = 10t
335/10 = 33.5 = t
It takes 33.5 minutes for the cans to have the same amount.

to find the answer subtract ( 10 3/8 - 7 1/3 = 3 1/24 ).
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]7 \frac{1}{3} + n = 10 \frac{3}{8} \\ [/tex]
[tex] \frac{21 + 1}{3} + n = \frac{80 + 3}{8} \\ [/tex]
[tex] \frac{22}{3} + n = \frac{83}{8} \\ [/tex]
Subtract sides 22 / 3
[tex] - \frac{22}{3} + \frac{22}{3} + n = - \frac{22}{3} + \frac{83}{8} \\ [/tex]
[tex]n = \frac{83}{8} - \frac{22}{3} \\ [/tex]
[tex]n = \frac{83 \times 3}{8 \times 3} - \frac{22 \times 8}{3 \times 8} \\ [/tex]
[tex]n = \frac{249}{24} - \frac{176}{24} \\ [/tex]
[tex]n = \frac{249 - 176}{24} \\ [/tex]
