Answer:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic = 1.525

we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Step-by-step explanation:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(4.94 - 4.50) ÷ 2.10/ sqrt(53)

0.44 / 2.10/ sqrt(53)

= 1.525

α = 1 - 98% = 0.02

Decision region :

Reject H0 ; if Pvalue < α

Pvalue = p(Z < 1.525) = 0.936

Pvalue = 0.936

Since Pvalue > α ; We fail to reject H0

Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Answer:

3.35 = (3 * 100) + (3 * 1/101) + (5 * 1/102)

3.35 = (3 * 1) + (3 * 1/10) + (5 * 1/100)

3.35 = 3 + 3/10 + 5/100

3.35 = 3 + 0.3 + 0.05

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Franklin can move in 4 direction after each step, therefore, the number of choices that Franklin have is,

Number of points = 4×4×4×4×4×4×4×4×4×4 = 4¹⁰ = 1048576

Answer:

the cash flow from operation is $267,397

Step-by-step explanation:

Given that

Revenues be $876,223

General and admin expense $352,479

Depreciation expense $131,455

Leasing expense $108,195

Interest expense $78,122

Tax rate is 34%

We need to find out the cash flow from operation

As we know that

Cash flow from operation = (Revenue - general & admin expense - depreciation - leasing - interest) × (1 - tax rate) + depreciation

= ($876,223 - $352,479 - $131,455 - $108,195 - $78,122) × (1 - 0.34) + $131,455

= $205,972 × (1 - 0.34) + $131,455

= $267,397

Hence, the cash flow from operation is $267,397

Answer:

31/15

Step-by-step explanation:

First, find the common multiplier of 20 and 12 (the lowest number that both fractions can be increased to). This is 60 (12 x 5 = 60, 20 x 3 = 60) and adjust the numerators accordingly: multiply 17 by five to get 85, and multiply 13 by three to get 39. Add them up to get 124/60, and then simplify - the answer will be 31/15! Hope this helps! Sorry if this was tough to understand, typing off my phone, so feel free to ask any questions :)

Answer:

The number of particles of soil and rock particles found in the water.

Step-by-step explanation:

Since we are filtering out small particles of soil and rocks, then we can assume that they are being reduced greatly with each filter. So we can assume that since the 500 is being reduced by 65%, then the 500 is the only other thig being reduced, which in this case is the particles of soil and rocks.

Answer:

  (x, y) = (0, 4)

Step-by-step explanation:

Since we have an expression for x, substitution works nicely.

  (8 -2y) +3y = 12 . . . . . . use the first equation to substitute for x in the 2nd

  y = 4 . . . . . . . . . . . . subtract 8, collect terms

  x = 8 -2(4) = 0 . . . . substitute for y in the first equation

The solution is (x, y) = (0, 4).

Step-by-step explanation:

Answer:

b. Mean = 18.5 pounds, standard deviation = 4.48 pounds, shape non-Normal

Step-by-step explanation:

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.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Subtraction of samples:

When two samples are subtracted, we have that the mean is the difference between the means and the standard deviation is the square root of the sum of the variances.

The mean weight of dogs in a certain city is 28 pounds with a standard deviation of 14 pounds. Sample of 10

This means that [tex]\mu_{D} = 28, s_D = \frac{14}{\sqrt{10}} = 4.4272[/tex]

Mean weights of cats is 9.5 pounds with a standard deviation of 2 pounds. Sample of 8.

This means that [tex]\mu_{C} = 9.5, s_{C} = \frac{2}{\sqrt{8}} = 0.7071[/tex]

Which of the following is an accurate description of the center, spread, and shape of the sampling distribution of the difference in the mean weight dogs and the mean weight of cats?

The mean is:

[tex]\mu = \mu_{D} - \mu_{C} = 28 - 9.5 = 18.5[/tex]

The standard deviation(spread) is:

[tex]s = \sqrt{s_{D}^2+s_{C}^2} = \sqrt{4.4272^2+0.7071^2} = 4.48[/tex]

Normal distribution subtracted by non-normal(sample of cats is less than 30, so wont be normal), will be non-normal.

Answer:

H.

Step-by-step explanation:

I believe this is the answer because when you look at the problem and see the rate of change pattern months go +2 , +3, +2, and +3. Then when you look at the cards rate of change 80-44=36, so +36 then 104-80=24, so +24. as you can see when you subtract the rates if change between the cards (36-24), you get 12. Therefore y=12x. next you go along with the pattern and find the y-intercept by doing 44-24=20. Sorry it is kinda hard to explain, but hope this helps!

Allen was given 20 cards , and he buys 12 cards each month

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Let the number of cards be y

Let the number of months be x

Let the first point be P ( 5 , 80 )

Let the second point be Q ( 7 , 104 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 104 - 80 ) / ( 7 - 5 )

m = 24 / 2

m = 12 cards per month

So , the equation of line is y - y₁ = m ( x - x₁ )

y - 80 = 12 ( x - 5 )

Adding 80 on both sides , we get

y = 12x + 20

So , when x = 0

y = 20 cards in the initial month

Hence , the equation of line is y = 12x + 20 and Allen has 20 cards in his initial month
