The width of a slot of a duralumin forging is (in inches) normally distributed with μ= 0.9000 and σ = 0.0030. The specification limits were given as 0.9000 ±0.0050. Show your calculations. Draw normal curves wherever appropriate.
a) What percentage of forgings will be defective?
b) What is the maximum allowable value of σ that will permit no more than 1 in 100 defectives when the widths are normally distributed with μ = 0.9000 and σ (revised value)?
Answers
Answer:
a) 9.56%
b) 0.0019
Step-by-step explanation:
a) Find the z-scores.
z = (x − μ) / σ
z₁ = (-0.0050) / 0.0030
z₁ = -1.67
z₂ = (0.0050) / 0.0030
z₂ = 1.67
Find the probability using a chart or calculator.
P(Z < -1.67 or Z > 1.67) = 2 P(Z < -1.67)
P(Z < -1.67 or Z > 1.67) = 2 (0.0478)
P(Z < -1.67 or Z > 1.67) = 0.0956
b) Use a chart or calculator to find the z-score.
P(Z < -z or Z > z) = 0.01
P(Z < -z) = 0.005
z = 2.576
Find the standard deviation.
z = (x − μ) / σ
2.576 = (0.0050) / σ
σ = 0.0019

Answers

Answer:
86 m^2
Step-by-step explanation:
The figure is equivalent to a rectangle that is 8 m by 12 m, with a triangle cut off. The width of the triangle is (12 m-8 m) = 4 m. The height of the triangle is (8 m-3 m) = 5 m.
Then the figure's area is ...
A = LW - (1/2)bh
A = (12 m)(8 m) -(1/2)(4 m)(5 m) = 96 m^2 -10 m^2
A = 86 m^2
The area of the figure is 86 square meters.

7 Henri Plans to sell cups of coffe at his school sports event
Henri has a hot water Container that holds 16 litres.
He needs about 200ml of hot water for each cup of coffee
a How many cups of coffee can he make from a full bottle of
water. Hens will charge 80 cents per cup of coffee he hopes
to sell 250 Cups of coffee
How
many
full Containers of water will he use.
How much mony will he make ?
Answers
Quantity of water with Henri = 16 litres
Quantify of water he will need for one cup of coffee = 200 ml
Number of cups of coffee he can make with a full cup of water :-
[tex] = 16 \: litres \: = 16000 \: ml[/tex]
[tex] = \frac{16000}{200} [/tex]
[tex] = 80 \: cups \: of \: coffee[/tex]
So , Henri can make 80 cups of coffee with one full bottle of water .
Quantity of water needed to make 80 cups of coffee = 16,000 ml
Quantity of water needed to make one cup of coffee :-
[tex] = \frac{16000}{80} [/tex]
[tex] = 200 \: ml[/tex]
So , 200 ml of water is needed to make one cup coffee .
Quantity of water he needs to make 250 cups of coffee :-
[tex] = 200 \times 250[/tex]
[tex] = 50000 \: ml[/tex]
So , Henri needs 50,000 ml of water to make 250 cups of coffee .
Number of water containers he will use :-
[tex] = \frac{50000}{16000} [/tex]
[tex] = 3.125 \\ = 3 \: water \: containers[/tex]
So , Henri will use 3 full water containers to make 250 cups of coffee .
Money charged per one coffee = 8 cents
Money charged for 250 coffees :-
[tex] = 250 \times 8[/tex]
[tex] = 2000 \: cents[/tex]
So , Henri will make 2000 cents if he sells 250 cups of coffee .
Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .

what are the y values of the equation y = 3x + 4 at x values -1, 0, 1, 2
Answers
Answer:
-2; 1; 4; 7
Step-by-step explanation:
To solve for y, plug the x value in to the expression
y = 3(-1) + 1
y = -3 + 1
y = -2
When x = -1, y = -2
y = 3(0) + 1
y = 0 + 1
y = 1
When x = 0, y = 1
y = 3(1) + 1
y = 3 + 1
y = 4
When x = 1, y = 4
y = 3(2) + 1
y = 6 + 1
y = 7
When x = 2, y = 7

Which of the following variable expressions would represent the area of a rectangle if its length was represented by x+5 and its width was represented by x-2?
x[tex]x^{2} +3x+10\\
x^{2} +3x-10\\
x^{2} -10x+3\\
x^{2} -10[/tex]
Answers
Answer:
B
Step-by-step explanation:
Remember that the area of a rectangle is given by the formula [tex]A=lw[/tex].
We know that the length is [tex](x+5)[/tex] and the width is [tex](x-2)[/tex]. Therefore, the area will be:
[tex]A=(x+5)(x-2)[/tex]
Expand. Use the Distribute Property. This yields:
[tex]A=(x+5)(x)+(x+5)(-2)[/tex]
Multiply:
[tex]A=(x^2+5x)+(-2x-10)[/tex]
Combine Like Terms:
[tex]A=x^2+(5x-2x)-10\\A=x^2+3x-10[/tex]
Therefore, our answer is B.
squares of side x are cut from each corner of an 8 inches x 5 inch in rectangle, so that its sides can be folded to make a box with no top. define a function in terms of x that can represent the area of the base of the box
Answers
Answer:
When we do not have anything cut of the rectangle, the area is:
8in*5in = 40in^2.
Now, when we cut squares of length x in the corners, the measures of the base will be:
8in - 2*x
5in - 2*x
We subtract two times x in each case because we cut the squares in the four corners. (below you can see a drawing of this situation, where the doted rectangle is the area that we want to calculate)
Then the area as a function of x is:
A = (8in - 2*x)(5in - 2*x) = 40in^2 + 4*x^2 - 26*x

A. ∆ABD ≅ ∆CDB by the SAS Postulate.
B, It is not possible to determine if the triangles are congruent.
C. ∆ABD ≅ ∆CDB by the SSS Postulate.
Answers
Answer:
A. ∆ABD ≅ ∆CDB by the SAS Postulate.
Step-by-step explanation:
You know lines AB and DC are congruent because of the lines on each. Additionally, angles B and D are congruent for the alternative interior angles rule and they also are marked as congruent in the image. Finally, DB is congruent to DB because of the reflexive property. So you have two sides and the included angle, this makes the SAS postulate true.
