Solving the problem systematically, the CPK for the size of the Santa on the Christmas Santa cup is approximately 0.2083.

The following formula must be used to determine the CpK (Process Capability Index) for the size of the Santa on a Christmas Santa cup:

CpK is equal to min[(USL - x) / 3 and (x - LSL) / 3].

Where: Target size + Acceptable Tolerance = 3.5 cm + 0.9 cm = 4.4 cm (USL = Upper Specification Limit)

Target size - Acceptable Tolerance = 3.5 cm - 0.9 cm = 2.6 cm x = Grand Mean = 3.4 cm LSL = Lower Specification Limit

1.28 cm is the Standard Deviation.

Let's figure out the CpK:

CpK is equal to min[(4.4-3.4)/(3*1.28), (3.4-2.6)/(3*1.28)]

adjusted to four decimal places, min[1 / 3.84, 0.8 / 3.84] = min[0.2604, 0.2083] = 0.2083

In light of this, the CPK for the Santa's size on the Christmas Santa cup is roughly 0.2083.

With regard to the study on NASA, the correct answer is Option A.

Since the mass of the Antarctic ice sheet increased each year during the given period, the function that best models this trend is an increasing function. Therefore, we can eliminate options B and D, which both suggest a decreasing trend.

Between options A and C, we can consider the rate of increase in the mass of the Antarctic ice sheet. The passage states that the mass increased by 112 billion tons of ice each year, which suggests a constant rate of increase. This is better modeled by a linear function rather than an exponential function. Therefore, the answer is option A) Increasing linear.

Answer:

Option C

The answer is 10.6

Explanation:

Here,

Total rise = 9 feet

Now, 1 foot = 12 inch

So, 9 x 12 inches = 108 inches

A riser height between 7 and 8 inches,

i.e., 8 ≤ h ≤ 7

Total riser = xh ...(1)

where x is the number of steps and h is the riser's height.

From equation (1),

x = Total riser ÷ h

Total riser = 108

h = 8 ≤ h ≤ 7

Thus,

x = 108/8 ≤ h ≤ 108/7

x = 14 ≤ h ≤ 15 ....(2)

Since the number of steps (x) is an odd number,

So, x = 15 [from equation (2)] (.°. 14 is not an odd number)

Also, from equation (1),

h = total riser/x

h = 108/x = 108/15 = 7.2 [it's between 7 and 8]

from riser-tread formula,

2h + d = 25

d = 25 - 2h

d = 25 - 2(7.2)

d = 25 - 14.4

d = 10.6

Thus, The answer is 10.6

-TheUnknownScientist

Answer:

Explanation:

The riser-tread formula states riser (R)+ tread (T) = 17 inches minimum, or 18 inches maximum.

Given R is between 7 - 8 inches, T must be between 9 - 11 inches.  So the only choices within this range are B) 9.5 and C) 10.6.

As the number of steps must be odd:

for R between 7 - 8 inches, the total rise of 9 feet i.e. 108 inches requires -

108/7 = 15.4 ~ 16 steps to

108/8 = 13.5 ~ 14 steps

15 steps is an odd number between 14 and 16.

With 15 steps, R = 108/15 = 7.2"

For choice B, R + T = 7.2 + 9.5 = 16.7" which is short of the riser-thread formula.

For choice C, R + T = 7.2 + 10.6 = 17.8" which satisfies the riser-thread formula and is the correct answer.

Edit: I missed the riser-thread formula in this question has been defined as  2h + d = 25. So the above calculation was done with a different definition of the formula but arrived at the same answer.

The weighted mean of all of Joe’s dice rolls is 7.1.

Explanation:

Since Joe is playing a game in which he has to roll two six-sided dice, and in his past ten rolls, he has rolled a sum of one 2, two 5s, three 7s, two 8s, one 10, and one 12 To determine the weighted mean of all of Joe's dice rolls, the following calculation must be performed:

(2 + (2 x 5) + (3 x 7) + (2 x 8) + 10 + 12) / 10 = X

(2 + 10 + 21 + 16 + 10 + 12) / 10 = X

71/10 = X

7.1 = X

Thus, the weighted mean of all of Joe’s dice rolls is 7.1.

The probability that the mean of a month's reviews will take Yoonie from 3.5 to 4.25 hrs is 0.7499.

We first get the z score for the two values. As z = (x - u) sqrt(n) / s, then as

x1 = lower bound = 3.5

x2 = upper bound = 4.25

u = mean = 4

n = sample size = 16

s = standard deviation = 1.2

Thus, the two z scores are

z1 = lower z score = (x1 - u) * sqrt(n) / s = -1.666666667

z2 = upper z score = (x2 - u) * sqrt(n) / s = 0.833333333

Using table/technology, the left-tailed areas between these z scores is

P(z < z1) = 0.047790352

P(z < z2) = 0.797671619

Thus, the area between them, by subtracting these areas, is

Answer:

\(S_{250} = 62750\)

Explanation:

Given

\(Sequence: 2 + 4 + 6 + ..... + 500\)

Required

Evaluate the sequence

The sequence shows an arithmetic progression and will be solved using the sum of n terms of an Arithmetic Sequence as follows:

\(S_n = \frac{n}{2}(a + L)\)

But first, we need to determine the value of n as follows:

\(L = a + (n - 1)d\)

Where

\(L = Last\ Term = 500\)

\(a = First\ Term = 2\)

\(d = Common\ Difference = 4 - 2 = 2\)

So:

\(L = a + (n - 1)d\)

\(500 = 2 + (n - 1) * 2\)

Open bracket

\(500 = 2 + 2n - 2\)

Collect Like Terms

\(2n = 500 + 2 - 2\)

\(2n = 500\)

Divide through by 2

\(n = 250\)

So:

\(S_n = \frac{n}{2}(a + L)\) becomes

\(S_{250} = \frac{250}{2}(2 + 500)\)

\(S_{250} = 125(2 + 500)\)

\(S_{250} = 125(502)\)

\(S_{250} = 125 * 502\)

\(S_{250} = 62750\)

Hence, the sum of the sequence is 62750

Answer:

0.4934

Explanation:

To obtain the area of the shaded region under then curve :

P(-2.48 < Z < 0) = P(Z < 0) - P(Z < - 2.48)

To obtain P( Z < x) = (x - μ) / s

Therefore :

P(Z < 0) - P(Z < - 2.48)

Using a Z probability calculator :

P(Z < 0) = 0.5

P(Z < - 2.48) = 0.0065691

Hence,

P(Z < 0) - P(Z < - 2.48) = 0.5 - 0.0065691

Therefore the shaded area under the normal probability curve is = 0.5 - 0.0065691 = 0.4934309

P(Z < 0) - P(Z < - 2.48) = 0.4934

Answer:

Explanation:

a) The mean of the population is given by:

Mean = (1 + 3 + 5 + 7) / 4 = 4

Therefore, the mean of the population is **4**.

b) There are six possible samples of two that can be drawn from the population:

{1,3}, {1,5}, {1,7}, {3,5}, {3,7}, {5,7}

The mean of each sample is:

{1,3}: (1+3)/2 = 2

{1,5}: (1+5)/2 = 3

{1,7}: (1+7)/2 = 4

{3,5}: (3+5)/2 = 4

{3,7}: (3+7)/2 = 5

{5,7}: (5+7)/2 = 6

Therefore, the means of all possible samples are:

2, 3, 4, 4, 5, 6

c) The sample mean of all possible samples can be calculated as follows:

Sample mean = (2 + 3 + 4 + 4 + 5 + 6) / 6 = 24 / 6 = 4

The sample mean is equal to the population mean. This is because the sample size is small and all possible samples have been considered. In general, as the sample size increases and more samples are considered, the sample mean will approach the population mean .

The 90 percent confidence interval for the population mean (μ) is (33.423, 38.577).

Confidence Interval = X ± Z * (s/√n)

Where:

s is the sample standard deviation.

Given:

X = 36

s = 7

n = 20

For a 90 percent confidence level, the Z-score is 1.645 (corresponding to the 0.05/2 critical values from the standard normal distribution table).

Plugging in the values:

Confidence Interval = 36 ± 1.645 * (7/√20)

Confidence Interval = 36 ± 1.645 * (7/√20)

= 36 ± 1.645 * (7/4.472)

= 36 ± 1.645 * 1.567

Answer:

2/5, or B.

Explanation:

Let's make the total work needed x. Then Worker A does 1/3x and 2/3x work is left for the other workers to do (we know this because 1-1/3 = 2/3). Thus, worker B comes and does 1/4 of the remaining work, which is 2/3x. So, worker B does 1/4*(2/3x), which gives you 1/6x. Then, to find the work left over for worker C, we subtract 1/6x from 2/3x, which gives us 3/6x, or 1/2x. Then. worker C does 1/5 of 1/2x, giving us 1/5*(1/2x), which is 1/10x. To find the remaining work, we do 1/2x - 1/10x to get 4/10x, which simplifies to 2/5x. Therefore, the answer is 2/5, or B.

Using the appropriate arithmetic operation, the fraction of the room which still needs to be painted is :2/5

Initial fraction = 1

Worker A : = 1/3

Worker B : = 1/4

Fraction left = 2/3 - 1/4(2/3)

Fraction left = 2/3 - 1/6 = (4 - 1)/6 = 1/2

Worker C : = 1/5

Fraction left = 1/2 - 1/5(1/2)

Fraction left = 1/2 - 1/10 = (5 - 1)/10 = 4/10 = 2/5

Hence, the fraction of the room left to be painted is 2/5
