Answer:
b
Step-by-step explanation:
80% +15% +5%=100
15/100= 0.15
5/100= 0.05
therfore
0.15 + 0.05 = number of flaws
=0.20
Based on the flaws that the manufacturer notices, we can infer that the expected number of flaws will be 0.25 which is e. none of the above.
The expected number of flaws is a weighted average of the percentages that have flaws:
=∑ (Percentage of flaws x Number of flaws)
The expected number of flaws is therefore:
= (80% x 0) + (15% x 1) + (5% x 2)
= 15% + 10%
= 0.25
In conclusion, you would expected the number of flaws to be 0.25.

Pls show work
Answer: x=0.3
Step-by-step explanation:
The solution of the linear equation 72 ÷ x = 3.6 ÷ 0.015 will be 0.03.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation with one variable is given as,
72 ÷ x = 3.6 ÷ 0.015
Simplify the equation, then the value of 'x' is given as,
72 ÷ x = 3.6 ÷ 0.015
x ÷ 72 = 0.015 ÷ 36
x / 72 = 0.015 / 36
x / 2 = 0.015
x = 0.03
The solution of the linear equation 72 ÷ x = 3.6 ÷ 0.015 will be 0.03.

X^2 + 10x = 0
How do I solve for a completed square ?
Answer:
12x=0
Step-by-step explanation:
x=0 because it is
Answer:
x = 0 x = -10
Step-by-step explanation:
First, use the AC method to figure out, what times what equals 0 and what adds up to equal 10, which would be 0 and 10.
Secondly, you would factor it out and be with
(x + 0)(x +10)=0
Third, you would set each one equal to 0
x + 10 = 0 x + 0 = 0
Solve from there to get your two x's
x = 0 and x = -10

Find the future value of an ordinary annuity of $200 paid quarterly for 6 years, if the interest rate is 10%, compounded quarterly. (Round your answer to the nearest cent.)
Answer:
Future value is $1543.12
Step-by-step explanation:
From the question, present value = $200, rate = 10%, years = 6.
So that future value of ordinary annuity can be calculated by,
FV = [tex]\frac{A{[(1+r)^{n} - 1]}}{r}[/tex]
where: FV is the future value, A is the annuity, r is the rate, and n is the number of years.
FV = [tex]\frac{200[(1+0.1)^{6}-1] }{0.1}[/tex]
= [tex]\frac{200[1.1^{6}- 1] }{0.1}[/tex]
= [tex]\frac{200*0.771561}{0.1}[/tex]
= [tex]\frac{154.3122}{0.1}[/tex]
FV = $1543.122
The future value of the ordinary annuity is $1543.12.

Are the angles 117 in degrees and 477 in degrees coterminal?
Answer:
Yes, they are coterminal.
Step-by-step explanation:
Coterminal angles are angles that are in multiples of -360 degrees or +360 degrees away from the initial angle.
Therefore, the easiest way to check if an angle is coterminal is set up an equation.
[tex]x + 117 = 477\\\\360 + 117 = 477\\\\477 = 477 \ \checkmark[/tex]
We get a true statement, which means that 117 is a coterminal angle of 477 and 477 is a coterminal angle of 117.
We can also determine the value in radians.
[tex]\displaystyle117 \times \frac{\pi}{180}\\\\\frac{117\pi}{180} = \frac{13\pi}{20}[/tex]
117° in radians is [tex]\displaystyle\frac{13\pi}{20}[/tex]. Coterminal angles for radians are multiples of [tex]2\pi[/tex], either negative or positive.
However, we also need to determine the value of 477 in radians too.
[tex]\displaystyle477\times\frac{\pi}{180}\\\\\frac{477\pi}{180} = \frac{53\pi}{20}[/tex]
So, if we add [tex]2\pi[/tex] to [tex]\frac{13\pi}{20}[/tex]:
[tex]\displaystyle\frac{13\pi}{20} + 2\pi\\\\\frac{13\pi}{20} + \frac{40\pi}{20} = \frac{53\pi}{20}[/tex]
Therefore, even in radians, 477° is an angle coterminal to 117°.
You are given 117°.
To find angles that are coterminal with 117°, we do the following:
117° + 360° = 477°
117° - 360° = 243°
As you can see, when we added 117° to 360°, we got 477°.
To answer your question, YES.
You now know that 117° and 477° are coterminal angles.
Keep in mind that 477° is not the only coterminal angle to 117°.

Hope this helps :D
Answer:
1.666......
( 1.6 recurring).
Step-by-step explanation:
As both numbers are multiples of 10 it makes it a bit easier to divide both by 10 to give 25 and 15. This will give the same result as 250/150.
Now do a long division , 25 divided by 15:
1 .66 <----------- 25 / 15 = 1 . 1*15 goes below the 25.
-------------------------
15 ) 25.0
15 <---------- subtract 25 - 15 = 10
100 <- bring down the zero(after the decimal point) & append to 10
90 < 15 divides into 100 6 times to give 90 . Place 6 above line.
100 < subtract 100 - 90 to give 10 then add 0
90 < as before 100/15 = 6 to give 6*15 = 90
If you carry on as above you'll see that we get 1.6666... and we could go on for ever. This is a recurring decimal and is usually written as 1.6 with a bar above the 6.
Let C(t) be the amount of U.S. cash per capita in circulation at time 1. The table, supplied by the Treasury Department, gives values of C(t) as of June 30 of the specificd year. Interpret and estimate the value of C'(1980).
Answer:
Following are the solution to this question:
Step-by-step explanation:
C'(t) was its time, in years, or t shift of cash per unit. That C'(1980) meaning, therefore, becomes the change of cashier's population to t = 1980.
They could either use t = 1970 or t = 1990 to approximate the C'(1980) price. When using t = 1970:
[tex]C'(1980) = \frac{[C(1980) - C(1970)]}{[1980 - 1970]}\\\\[/tex]
[tex]= \frac{(571 - 265)}{10}\\\\ = \$ \ 30.6 \\[/tex]
t = 1990:
[tex]C'(1980) = \frac{[C(1980) - C(1990)]}{[1980 - 1990]}[/tex]
[tex]= \frac{(571 - 1063)}{ -10} \\\\= \$ \ 49.2[/tex]

Answer:
multiplicative inverse of 0.13 is -100/30
The required inverse of 0.13 is 1 / 0.13.
Given that,
To find the multiplicative inverse of 0.13.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
The inverse of the particular number is that number when it is multiplied by the number that gives the unit. i.e. ab = 1
Here,
Let the required multiplicative inverse be x,
The product of a number and its multiplicative inverse is equal to 1
So,
0.13*x = 1
x = 1 / 0.13
Thus, the required inverse of 0.13 is 1 / 0.13.

The diameter of a pipe is normally distributed, with a mean of 0.4 inch and a variance of 0.0009. What is the probability that the diameter of a randomly selected pipe will exceed 0.418 inch
Answer:
P(X > 0.418) = 0.27425
Step-by-step explanation:
We are given;
Population mean; μ = 0.4 inch
Variance; Var = 0.0009
Sample mean; x¯ = 0.418
First of all let's get the standard deviation which is;
σ = √Var
σ = √0.0009
σ = 0.03
Now, z - score formula is;
z = (x¯ - μ)/σ
z = (0.418 - 0.4)/0.03
z = 0.6
We want to find the probability that the diameter of a randomly selected pipe will exceed 0.418 inch. Thus;
P(X > 0.418) = 1 - P(X ≤ 0.418)
From z-distribution table attached, P(X ≤ 0.418) = P(Z) = 0.72575
Thus;
P(X > 0.418) = 1 - 0.72575
P(X > 0.418) = 0.27425
