Automated manufacturing operations are quite precise but still vary, often with distribution that are close to Normal. The width in inches of slots cut by a milling machine follows approximately the N(1,0.001)N(1,0.001) distribution. The specifications allow slot widths between 0.999750.99975 and 1.000251.00025. What proportion of slots meet these specifications

Answer:the answer is c

Step-by-step explanation:

Answer:

Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution

The formula for Z score is Z = [X - mean ]./ (standar deviation)

Here X = 930.00; mean = 900.00; and standard deviation = 15.00

Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00

Answer: 2.00

Answer:

5, -9

Step-by-step explanation:

(x - 5)(x + 9) = 0    These are factors, to get the roots, just set each one equal to zero

x - 5 = 0

x = 5

x + 9 = 0

x = -9

Answer:

Postive 5 and negative 9.

Step-by-step explanation:

So remember, all we have to do is set each of the parethese to zero and solve. It should look like this:

x-5=0 and x+9=0

For the first equation we have made, jsut add 5 to both sides so x is alone. This will get you:

x=5

So the first answer for x is 5.

Now lets solve our second equation and find the second answer for x.

So all we have to do for this one is subtract 9 from both sides. This should get you:

x=-9

So now we know that our two answers for x is 5 and -9.

These two answers seem to be on your list as #2 answer and #3 answer.

Answer:

f(4) = 7

Step-by-step explanation:

The notation for these type of problems is very confusing. Just remember that f(x) is the same thing as y (or some variable). Even if there is a number or something on the inside of the parentheses, it's still just a variable.

In our case

f(a) = 2(a + 4) -9

could be rewritten as

y = 2(a + 4) - 9

the thing on the inside of the parentheses signifies what the equation is dependent on.

so when is says f(4), it just want's you to trade out a for a 4, but the equation is still the same.

f(4) = 2((4) + 4) - 9

Now, just follow the order of operations

f(4) = 2(8) - 9

f(4) = 16 - 9

f(4) = 7

Answer:

No.

Answer:

7)Bagel costs $3.5 and muffin cost $1.25

8) Ticket is $9 while snacks are $2

9) Correct because left hand side is zero

10) Correct because they both have same slope and same y-intercept

Step-by-step explanation:

7) Let bagel be x and muffin be y.

Thus;

For Aaron;

x + 3y = 7.25 - - - (1)

For bee;

x + 2y = 6 - - - (2)

Subtract eq 2 from eq 1 to get;

y = 1.25

Put 1.25 for y in eq 2;

x + 2(1.25) = 6

x + 2.5 = 6

x = 6 - 2.5

x = 3.5

Bagel costs $3.5 and muffin cost $1.25

8) Let movie ticket be x and snacks be y.

Thus;

2x + 3y = 24 - - - (1)

3x + 4y = 35 - - - (2)

Multiply eq(1) by 3 and eq(2) by 2 to get;

6x + 9y = 72 - - - (3)

6x + 8y = 70 - - - (4)

Subtract eq 4 from eq 3 to get;

y = 2

Put 2 for y in eq 3;

6x + 9(2) = 72

6x + 18 = 72

6x = 72 - 18

6x = 54

x = 54/6

x = 9

Ticket is $9 while snacks are $2

9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.

Thus, no solution exists because we can't isolate the variable to get an answer.

10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.

In this case, their y-intercept which is when x is 0 is;

3(0) + y = 9

y = 9

Their slope is also the same equal to 3.

Answer:

  25%

Step-by-step explanation:

A percentage change is calculated using the formula ...

  pct change = ((new value) - (old value))/(old value) × 100%

For your numbers, this is ...

  pct change = (250 -200)/200 × 100% = 50/200×100% = 25%

The selling price was 25% more than the cost price.

Answer:

The answer is 0

Step-by-step explanation:

Since any number squared by zero is 1 then x^0 is 1 and since -1^4 is -1 that gives you -1+1=0

The required confidence interval is (5.5<<5.7) for the mean number of dresses purchased each year.

As per the question, the given data as

[tex]\bar{x}[/tex] = 5.6

σ = 1.3

n = 650

The Z-critical value at the 95% confidence level is 1.960.

To determine the 99% confidence interval for the mean number of dresses purchased each year.

95% CI = [tex]\bar{x}[/tex]  ± Z(Cr)(s/√n)

⇒ -5.6 ± 1.960(1.3/√650)

⇒ 5.6±0.100

⇒ (5.500,5.700)

Round to near 1 decimal place

⇒ (5.5,5.7)

Therefore, the required confidence interval is (5.5<<5.7)

Answer:

30 ft is the answer.

Step-by-step explanation:

a = 24 ft

b = 18 ft

c = ?

According to the Pythagoras theorem,

a² + b² = c²

24² + 18² = c²

576 + 324 = c²

c² = 900

c = 30 ft

∴ The opposite corners of the living room are 30 ft apart.

4 is Q2 (median)

9 is Q3

The upper quartile for the given data set is 3.

In statistics, a quartile is a type of quantile which divides the number of data points into four parts, or quarters, of more-or-less equal size. The data must be ordered from smallest to largest to compute quartiles; as such, quartiles are a form of order statistic.

Given is a data as given below -

1,1,3,4,4,4,8,9,13,15

The first quartile Q1 is the 25th percentile. It is also called as the upper quartile. So, we can say that that the upper quartile is 3.

Therefore, the upper quartile for the given data set is 3.

Answer:

443.736759 day

Step-by-step explanation:

To convert a seconds to days, divide the time by the conversion ratio.

So.....

One day is equal to 86,400 seconds, you can use this formula to convert:

 days = seconds ÷ 86,400

The time in days is equal to the seconds divided by 86,400.

Example: Convert 50,000 seconds to days (use the formula above)

50,000 sec = (50,000 ÷ 86,400) = 0.578704 day
