Step-by-step explanation:
The candy produced by a company has a sugar level that is normally distributed with a mean of 16.8 grams and a standard deviation of 0.7 grams. The company takes readings of every 10th bar off the production line. The reading points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4. Is the process in control or out of control and why?
Answer:
It is not in control because at least two of the of the data points are more than 2 standard deviations from the mean are far apart.
18.3,18.4 > 18.2 Upper Control limit
14.9, > 15.4 Lower Control Limit
Step-by-step explanation:
Find the limits using μ ± 3σ and μ ± 2σ
Using μ ± 3σ
Upper Control Limit = μ + 3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9
Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7
Using μ ± 2σ
Upper Control Limit = μ + 2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2
Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4
The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.
Rearranging these data points 14.9, 16.1, 16.5, 17.3, 17.4, 18.3,18.4.
We see from the above that it is out of control because the values jump above and below the mean.
It is not in control as two of the of the data points are more than 2 standard deviations from the mean are far apart.

a circle has a diameter of 6 centimeters what is the approximate area of the circle
Answer:
28.26 [tex]cm^{2}[/tex]
Step-by-step explanation:
The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.
The formula for the area of a circle is: π[tex]r^{2}[/tex]
Plugging 3 into the radius, we have:
[tex]3^{2}[/tex] × π =
9 × π
We can round π to 3.14
9 × 3.14 = 28.26

Which of the following best defines an input? (4 points)
a
An input is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.
b
An input is a special type of relation for which there is a rule that pairs each input with exactly one output.
c
An input is a set of ordered pairs in which no y-value repeats.
d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Answer:
d
Step-by-step explanation:
hope this helped!!!!!
Answer: d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Step-by-step explanation: Its d because the function has one output for each input so d is the correct answer.
I also saw the question on a different persons test in brainly and it was d.

Simplify these radicals
Answer:
9) 7sqrt(2)
11) 8sqrt(2)
13) 3sqrt(7)
Step-by-step explanation:
9) factor the radicand 98 into 7*7*2, 7^2*2, and then factor out the 7 squared to the outside of the radical to get 7 square roots of 2
11) factor the radicand 128 into 8*8*2, 8^2*2, and then factor out the 8 squared to the outside of the radical to get 8 square roots of 2
13) factor the radicand 63 into 3*3*7, 3^2*2, then factor out the 3 squared outside of the radical to get 3 square roots of 7
Write an expression that represents the perimeter of triangle.
Combine like terms.
3.x
3x
15
Perimeter of triangle:
If the perimeter of the triangle is 90, what is the value of x?
The value of x is 12.5
A triangle has 3 sides: side A, side B and side C
Perimeter of a triangle = side A + side B + side C
Side A = 3x
Side B = 3x
Side C = 15
Perimeter of a triangle = 90
Perimeter of a triangle = side A + side B + side C
90 = 3x + 3x + 15
90 - 15 = 3x + 3x
75 = 6x
x = 75 / 6
x = 12 3/6
x = 12 1/2
= 12.5
x = 12.5

1. What is a function?
2. How do you calculate the y-intercept of a function based on the graph, an equation, or 2 given points?
3. What is a composite function?
Answer:
see explanation
Step-by-step explanation:
1
A function is a relationship between 2 variables that gives exactly one output value for every input value.
2
From a graph the y- intercept is the value of the y- coordinate on the y- axis where the function crosses the y- axis.
If c is the y- intercept then its coordinates are (0, c )
Given an equation to find the y- intercept, let x = 0 in the equation and solve for y ( the y- intercept )
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given 2 points, calculate m using the slope formula, then obtain the equation using either of the 2 points. The y- intercept is then the value of c
3
The composition of functions is an operation in which you use one function as the input into another and perform the operations on that input function.
Given f(x) and g(x) then
f(g(x)) and g(f(x)) represents the composition of the functions

When Aidan had his picture taken, the photographer charged a $10 sitting fee and $6
for each sheet of pictures purchased.
a. Write a function for the situation.
b. State what x and y represent in the function.
c. Graph the function.
ASAP
Answer:
10y x 6x = y = sitting fee x = $6
Step-by-step explanation:
The function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the total charge is y and the number of the sheets is x.
So according to the problem:
y = 10 + 6x
Here y represents the total charge and x represents the number of sheets.
Thus, the function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.
