Please help me with this question!

Answer:

The capability index for the process is 0.889

Step-by-step explanation:

Here, we want to compute the capability index for the process

To get this, we need some important parameters which we already have stated in the question

USL ( upper standard limit) = 0.048

LSL (lower standard limit) = 0.032

mean = 0.04

standard deviation = 0.003

We apply the formula as seen in the attachment below

Kindly understand that we are to calculate the Z upper and Z lower

The smallest value between the two will be our Z minimum

This is what we shall apply in the capability index formula which mathematically is;

Z minimum/3

From calculation:

Z lower = Z upper = 2.67

So therefore;

capability index = 2.67/3 = 0.889

Answer:

The roots of the polynomial are;

3 + 2i

and 3-2i

Step-by-step explanation:

Here, we want to solve the given polynomial using the completing the square method

We start by dividing through by 8

This will give;

x^2 - 6x = -13

To complete the square, we simply divide the coefficient of x by 2 and square it

We have this as -6/2 = -3

square it;; = (-3)^2 = 9

Add it to both sides

x^2 - 6x + 9 = -13 + 9

x^2 - 6x + 9 = -4

(x-3)^2 = -4

Find the square root of both sides

x-3 = ±2i

x = 3 + 2i

or x = 3-2i

Answer:

Here's just the answers without all the work for easier reading. Answers are bolded.

Step-by-step explanation:

First problem answer: x2 + -6 x = -13

Second problem answer: x2 – 6x + 9 = –13 + 9

Third problem answer: (x + -3)² = -4

Fourth problem answer: 3 + 2i

Step-by-step explanation:

The slope of the line with equation y=2x+3 is 2 . So, any line parallel to y=2x+3 has the same slope 2 .

Hello!

Parallel lines have the same slope. So if one line has a slope of 2, the line parallel to it has a slope of 2 as well.

Therefore, the slope is 2. Hope it helps.

Answer:

12

Step-by-step explanation:

There are 32 female casts in a school play

The ratio of male to the female role is 3:8

Therefore the number of male casts in the school play can be calculated as follows

3/8= x/32

Cross multiply

8x = 32×3

8x= 96

x= 96/8

= 12

Hence there are 12 male casts in the school play

Answer:

a) A sample of 256 was used in this survey.

b) 45.14% probability that the point estimate was within ±15 of the population mean

Step-by-step explanation:

This question is solved using the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

a. How large was the sample used in this survey?

We have that [tex]s = 25, \sigma = 400[/tex]. We want to find n, so:

[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]

[tex]25 = \frac{400}{\sqrt{n}}[/tex]

[tex]25\sqrt{n} = 400[/tex]

[tex]\sqrt{n} = \frac{400}{25}[/tex]

[tex]\sqrt{n} = 16[/tex]

[tex](\sqrt{n})^2 = 16^2[tex]

[tex]n = 256[/tex]

A sample of 256 was used in this survey.

b. What is the probability that the point estimate was within ±15 of the population mean?

15 is the bounds with want, 25 is the standard error. So

Z = 15/25 = 0.6 has a pvalue of 0.7257

Z = -15/25 = -0.6 has a pvalue of 0.2743

0.7257 - 0.2743 = 0.4514

45.14% probability that the point estimate was within ±15 of the population mean

Answer:

0.1169

Step-by-step explanation:

We solve the question using the z score formula

z = (x-μ)/σ/√n where

x is the raw score = 4800 miles

μ is the population mean = 4550 miles

σ is the population standard deviation = 1470 miles

n is the random number of samples = 49 drivers

Greater than sign = >

For x > 4800 miles

z = 4800 - 4550/1470/√49

= 4800 - 4550/1470/7

= 4800 - 4550/210

= 1.19048

Probability value from Z-Table:

P(x<4800) = 0.88307

P(x>4800) = 1 - P(x<4800)

P(x>4800) = 1 - 0.88307

P(x>4800) = 0.11693

Approximately to 4 decimal places = 0.1169

Therefore, the probability that these drivers have a sample mean greater than 4800 miles is 0.1169

Answer:

The point (-2, -4) is a minimum.

Hence, option A is correct.

Step-by-step explanation:

We know that graph of a Parabola illustrates a U-shaped curve.

The graph of Parabola has an important characteristic, it consists of an extreme point which is termed as 'vertex'.

When a parabola opens up, the vertex will be the lowest point on the Parabola graph.

When a parabola opens up, the vertex will be the lowest point on the Parabola graph. This lowest point is the minimum value of the parabola function.

From the given Parabola graph, it is clear that the parabola opens up.

Thus, the vertex will be the lowest point on the Parabola graph which is also the minimum value.

It is clear that the vertex of the parabola is located at (-2, -4).

Therefore, the point (-2, -4) is a minimum.

Hence, option A is correct.
