A process produces a certain part with a mean diameter of 3 inches and a standard deviation of 0.05 inches. The lower and upper engineering specification limits are 1.80 inches and 3.05 inches. What is the Cp (measure of potential capability)
Answer:
The correct answer is 4.167
Step-by-step explanation:
According to the given scenario, the calculation of the Cp i.e. measure of potential capability is as follows;
= (USL - LSL) ÷ 6 × standard deviation
= (3.05 inches - 1.80 inches) ÷ 6 × 0.05
= 1.25 ÷ 0.3
= 4.167
hence, the calculation of the Cp i.e. measure of potential capability is 4.167
why is 10 x 10 is 1 less than 9 x 11
Answer: It's the other way around and it is because 10 x 10 is adding 10+10+10+10+10+10+10+10+10+10, while 11x9 is just 9 11s added together.

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of the group should like MATH 123?
Answer:
680 students
Step-by-step explanation:
The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.
Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:
number of people that like MATH 123 = 68% of the population
number of people that like MATH 123 = 0.68 * 1000
number of people that like MATH 123 = 680 students
A skating rink charges $6.25 for skate rentals for people of all age groups. If C
represents the total number of children who rented skates and A represents the
total number of adults who rented skates, which expression best represents the
total money earned by the skating rink for the rental of skates?
a. 6.25 + a + c
b. 6.25a + 6.250
c. 6.25 (a + c)
d. 6.25a X 6.250
Answer:
C: 6.25 (a+c)
Step-by-step explanation:
Since the price for all ages is $6.25
Both children and adult (c,a) would be multiplied by the price to get the total money earned

The only decimal that contains a digit that represents ten times the value of the digit to its' right is; 33.458
How to Interpret Decimals?From the question, we want to find the digit that represents ten times the value of the digit to its' right.
Now, when it comes to decimals, there is the whole number part which is the left side of the decimal while there is a fraction part which is the right side of the decimal.
Now, the decimal values given are;
36.295
33.458
37.889
Let us analyze each of them;
1) 36.295 = 30 + 6 + 2/10 + 9/100 + 5/1000
We can see that there is no number that is ten times the number to it's immediate right.
2) 33.458 = 30 + 3 + 4/10 + 5/100 + 8/1000
We can see that 30 is ten times the number to it's immediate right which is 3.
3) 37.889 = 30 + 7 + 8/10 + 8/100 + 9/1000
We can see that there is no number that is ten times the number to it's immediate right.

The value of x is 6
How to determine the valueFrom the information given, we have that;
Line RS = 4x - 9Line ST = 19Line RT = 8x - 14It is important to note that line RT is a line with segments RS and ST and S and the line between R and T
This can be expressed as;
RS + ST = RT
substitute the values into the equation, we have;
4x - 9 + 19 = 8x - 14
collect like terms
4x - 8x = -14 + 9 - 19

Identify the property illustrated. (Commutative, Associative, Identity, Property of Zero, Property of -1)
1. -1 • (-6) =6
2. 0 • (-76.3) =0
3. (3x) y = 3 (xy)
4. 0.3 • (-3) = -3 • 0.3
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)
As we know that,
The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Identity property states that a number, known as the identity, can be added to, subtracted from, multiplied by, or divided into a number without changing the number.
Zero property of multiplication is defined as “when we multiply any number by zero, the resulting product is always a zero”.
Multiplicative property of -1 atates that any number multiplied by -1 gives the same but with its opposite sign.
From the given example we can say that
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)

Answer:
Draw an arrow from the origin to (4, 0)
Step-by-step explanation:
u-v+w
= <-3, -4> - <-4, -1> + <3, 3>
= <4, 0>
We want to perform a sum of vectors and draw the resultant vector. The resultant vector will be <4, 0> and its graph can be seen at the end.
If we see the image, we can write the vectors as:
w = <3, 3>u = <-3, -4>v = <-4, -1>Now we want to sum:
u - v + w
Remember that in the sum of the vectors we just add (subtract) the correspondent components, then we will have:
u - v + w = <-3, -4> - <-4, -1> + <3, 3> = <-3 + 4 + 3, -4 + 1 + 3> = <4, 0>

Suppose lines EF and GH are reflected over the line y = x to form the lines JK and LM. Which statement would be true about the lines?
A.
Line JK and line LM will be parallel.
B.
Line JK and line LM will be perpendicular.
C.
The slope of line JK will be the same as the slope of line EF.
D.
The slope of line LM will be the negative reciprocal of the slope of line GH.
Answer:
A.
Step-by-step explanation:
I believe the answer is A. (Line JK and line LM will be parallel) because lines EF and GH are parallel. Therefore if the are just reflected, the new set of lines will also be parallel.
EF: (-9,1) (-4,9)
[tex]\frac{1-9}{-9+4}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
GH: (-5,-2) (0,6)
[tex]\frac{-2 - 6}{-5-0}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
Same slope and different y-intercept means the lines a parallel

If the function h(t) = tan(5t +4 ) using chain rule we found values h'(1)= 6.02 and h"(1) = -27.24
What is chain rule for differentiation?Chain rule for differentiation states that the differentiation of the composition of two functions f, g
(fоg)' = f'(g(x))* g'(x) , where ' represents first derivative with respect to independent variable x .
For three functions : x, y, t
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
Given h(x) = tan(5t+4)
Let f(t) = tan t and g(t) = 5t+4
f'(t) = sec² t and g'(t) = 5
Then h(t) = fоg(t)
Using chain rule of differentiation:
h'(t) = (fоg(t))' = f'(g(t))* g'(t) = sec²(5t+4) *(5) = 5 sec²(5t+4)
let x(t) = 5t², y(t) = sec(t), z(t) = 5t+4
x'(t) = 10t , y'(t) = sect tan t , z'(t) =5
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
h"(t) =(x(y(z(t))))'= 10 sec(5x+4) * sec(5t+4)tan(5t+4)*5
h"(t) = 50sec²(5t+4)tan(5t+4)
The value of h'(t) at t =1
h'(1 ) = 5 sec²(5(1)+4)= 5 sec²(9) =6.02
h"(1) = 50sec²(5(1)+4)tan(5(1)+4) = 50sec²(9)tan(9) = -27.24
Therefore, the values h'(1 ) = 6.02 and h"(1) = -27.24

5. Find JK to the nearest whole number.
A
Answer:
JK ≈ 63 units
Step-by-step explanation:
Using the sine ratio in the right triangle
sin44° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{90}[/tex] ( multiply both sides by 90 )
90 × sin44° = JK , that is
JK ≈ 63 ( to the nearest whole number )
Answer:
Sin(x) = Opposite ÷ Hypotenuse
Sin(44) = JK ÷ 90
0.6946583705 = JK ÷ 90
0.6946583705 × 90 = JK

Joshua drove his car a distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
6 liters of gasoline
Step-by-step explanation:
Since, 1 km = 0.6214 miles
Therefore, 100 km = 0.6214 × 100 = 62.14 miles
∵ For 431.8 miles of driving Joshua required amount of gasoline = 10.4 gallons
∴ For 1 mile of driving gasoline required = [tex]\frac{10.4}{431.8}[/tex] gallons
∴ Gasoline required to drive 62.14 miles = [tex]\frac{10.4}{431.8}\times 62.14[/tex] gallons
= 1.4967
≈ 1.5 gallons
∵ 1 gallon of gasoline = 3.8 liters
∴ 1.5 gallons of gasoline = 3.8×1.5
= 5.7
≈ 6 liters
The number of liters of fuel should be 6 liters.
Calculation of number of liters:Since distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol).
So,
Since, 1 km = 0.6214 miles
Now
100 km = 0.6214 × 100 = 62.14 miles
The number of liters should be
[tex]= 10.4 \div 431.8 \times 62.14 \times 3.8[/tex]
