Answer:

The answer is below

Step-by-step explanation:

a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.

b) Given that:

μ = 11.2 minutes, σ = 4.8 minutes, n = 45

The z score determines how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma} \\For\ a\ sample\ size(n)\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]

For x < 10 minutes

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\ z=\frac{10-11.2}{4.8/\sqrt{45} }= -1.68[/tex]

Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) =  0.0465

Answer:

Bachelors = $51,000

Masters = $66,000

Step-by-step explanation:

M + B = 117,000

M = 2B - 36,000

2B - 36,000 + B = 117,000

3B = 153,000

B = 51,000

M = 2(51,000) - 36,000 = 66,000

The yearly salary of a bachelor's degree and a master's degree is 51 thousand and 66 thousand dollars respectively.

To write numerical expressions from given statements use logic as what is twice of a number what is 6 times of a number and many more.

Suppose a is thrice of b means a is 3 times as big as b.It can be written as a = 3b.

According to the given question  the average yearly salary of an individual whose final degree is a masters is 36 thousand dollars less than twice that of an individual whose final degree is a bachelors.

Assuming yearly salary of a bachelor's degree is x thousand dollars.

∴ yearly salary of an individual with master's degree is

= (2x - 36) thousand dollars.

Given combining these two individual they make 117 thousand dollars.

∴ x + (2x - 36) = 117

 3x = 117 + 36

 3x = 153

   x = 153/3

   x = 51.

So, Yearly salary of an individual who has a bachelors degree is 51 thousand dollars and yearly salary of an individual who did masters is {(2×51) - 36} = 102 - 36 = 66 thousand dollars.

b) The difference that changing from a weighted average to FIFO method of inventory valuation is likely to have on an entity's profit or loss:

The weighted average method of inventory valuation accumulates and assigns cost of inventory based on the weighted average.  This simply means that the cost of goods available for sale is obtained and then divided by the number of goods available for sale.  The average cost obtained is used to value the cost of goods sold and the ending inventory.

On the other hand, the FIFO method assumes that goods that are first to be in the store are the ones that are sold first.  This means that the cost of goods sold is valued at the cost of the first goods that are available for sale and the ending inventory is valued at the cost of newly purchased goods, since they are the ones that are still in stock by the FIFO assumption.

The implication of moving from the weighted average method to the FIFO method is that the FIFO method reflects the cost of newly acquired goods in the ending inventory better than the average cost using the weighted average, especially if prices are rising.

Step-by-step explanation:

The total number of individuals included in this summary is the sum of the counts {119, 179, 239, 299, 359).  That comes to 1195 individuals.

No, the info given here is insufficient to enable identifying the exact values of all the service times.

Answer:

[tex]\bold{t = f(s) = \dfrac{6.2}{s}}[/tex]

Step-by-step explanation:

Given that distance is 10,000 meter or 6.2 miles.

Time taken is [tex]t[/tex] minutes.

Average speed is [tex]s[/tex] miles/minutes

To find:

Equation to determine time 't' as a function of average speed 's' = ?

t is in minutes and

s is in miles/minute

Solution:

First of all, let us have a look at the formula for Average Speed:

[tex]\text{Average Speed} = \dfrac{\text{Total Distance Traveled}}{\text{Total Time Taken}}\\\Rightarrow \text{Total Time Taken} = \dfrac{\text{Total Distance Traveled}}{\text{Average Speed}}\\[/tex]

Now, we are given that Time, [tex]t[/tex] should be in minutes and

Average speed, [tex]s[/tex] must be in miles per minute

That means, we must have distance in miles.

Putting all the values in above formula.

So, the formula or equation becomes:

[tex]t = \dfrac{6.2}{s}[/tex]

Therefore the equation to find time, [tex]t[/tex] in minutes as a function of Average Speed, [tex]s[/tex] is given as:

[tex]\bold{t = f(s) = \dfrac{6.2}{s}}[/tex]

Answer:

y = 3x + 26

Step-by-step explanation:

Plug in the slope and the given point into the equation, y = mx + b

Solve for b (y intercept)

8 = 3(-6) + b

8 = -18 + b

26 = b

Now, plug this into the equation with the slope:

y = 3x + 26 will be the equation

Answer:

y=3x+26

Step-by-step explanation:

We can start by writing this line in point-slope form.

Point-slope form is:

y-y1=m(x-x1)

This is where m is the slope

x1 and y1 are the x and y coordinates of a given point on a line.

With the given info, we are able to write the following equation:

y-8=3(x-(-6))

y-8=3(x+6)

We can now simplify that to slope-intercept form which is y=mx+b

m is slope and b is y-intercept in this form.

y-8=3(x+6)

Distribute

y-8=3x+18

Add 8 to both sides.

y=3x+26

Answer: undefined

Step-by-step explanation:

#1 use the horizontal and vertical line concept

- when the line is horizontal, the slope is 0

- when the line is vertical, the slope is undefined

- Thus, in this case, the line is vertical, the slope is undefined.

Answer:

It will be  in the total of 2 subsets.

Step-by-step explanation:

The only subsets of the set containing 5564 is the empty set and the set {5564}.

5564 belongs to the set of real numbers, the set of natural numbers, the set of integers, the set of whole numbers and the set of rational numbers.

Answer:

5564 belongs to the following subsets of real numbers:

real numbers

rational numbers

integers

whole numbers

natural numbers (counting numbers)

----

You can keep on going. You can even say this number belongs to the set of even integers.

Step-by-step explanation:

If you are looking for what subsets of the real numbers that 5564 belong to, then there is a lot of real number subsets to which this number can belong.

This number doesn't have an imaginary part so it's it a number.

We don't have to say it is complex (though it is), because we are looking at subsets of real numbers, not subsets of complex numbers (to which complex numbers are a subset of itself).

So the real numbers are divided into rational versus irrational.

The definition of rational numbers is any number that can be written as a fraction where the top and bottom are integers (of course the bottom integer cannot be 0). -(I will define integers in a second.)

Irrational numbers is any real number that isn't rational.

So since 5564 can be written as 5564/1, then it is rational.

A subset of rational numbers is integers (integers are in consequence also a subset of real numbers since rational numbers are a subset of real numbers).

Integers are numbers you count with, the opposite of those numbers you count with, or 0.

You can count to 5564 so 5564 can be further categorized as real rational integer.

Another subset of real numbers is whole numbers. The whole numbers is just the counting numbers and 0. Again since you count to 5564, then it is a whole number.

The natural numbers (counting numbers) is a subset of real numbers. Again, since 5564 can be counted to, it is a natural number.

Step-by-step explanation:

Start by recognizing the significant figures of the number in question. the first factor to include in the scientific notation should have a non-zero digit followed by a decimal point, and whatever other significant figures follow. Make sure you count how many places you need to move the decimal point to get to the first significant figure for the quantity. If you moved the decimal point to the left in order to get to the first significant figure, you have to include a positive exponent for the base ten, and that exponent is the number of places you counted. If you moved to the right when moving the decimal point to locate it after the first significant figure, you need to include the negative of the number of places you counted in the exponent of the accompanying base 10.

Step-by-step explanation:

Since AB is equal to radius of circle,

And CF is the radius of circle,

The correct one is:

Correct answer choice is C. AB=SF

The correct answer is A. 73 books

Explanation:

The first step to find the answer is to know the total volume/space in the bookcase. This can be calculated by using the formula v (volume) = h (height) x l (length) x w (width) or multiplying the three sides given because this is the formula for a cuboid and most bookcases have this shape.

v (volume) h x l x w

v = 36 in x 24 in x 12 in

v =  10368 in

According to this, the total volume of the shelf is 10368 in. The next step is to calculate the volume of 1 book. This can be found using the same process and formula.

1.5 in x 11 in x 8.5 in = 140.25 in

Finally, to know how many books can fit in the bookshelf divide the total volume of the bookshelf into the volume of one book.

10368 ÷ 140.25 = 73.9

Thus, the total books that can be fit in the bookshelf is 73

Answer: Option C.

Step-by-step explanation:

Xmin, Xmax, Ymin, and Ymax represent the minimum/maximum values that X and Y can take.

We know that the scale in Y and X is 10.

This means that each mark in each axis represents 10 units.

Now, let's go to the vertical axis (y-axis)

Counting from the (0, 0) we can count:

4 marks up

4 marks down.

So if each mark represents 10 units, 4 marks are 40 units.

Then the range for Y is {-40, 40}

Now for the horizontal axis.

We can count 3 marks on each side, and with the same reasoning as before, we can find that the range for X is: {-30, 30}

Then we have that:

Xmin = -30

Xmax = 30

Ymin = -40

Ymax = 40

Now, as a point is defined as (X, Y)

This region can be written as:

{Xmin, Xmax} by {Ymin, Ymax}

or, replacing the values:

{-30, 30} by {-40, 40)

So the correct option is C.

C] X min and X max = (-300, 300) and Y min and Y max = (-400, 400)

Xmin, Xmax, Ymin and Ymax denote minimum and maximum values of X and Y respectively.

As x and Y scale are 10 each, the minimum and maximum values can be found by multiplying the units with respective scales.

On X (Horizontal Axis), there are 3 units of line segments each on both left & right sides of origin.

Hence X min & X max = (0 - 300, 0 + 300) = (-300, +300) respectively.

On Y (Vertical Axis), there are 4 units of line segments each on both upwards & downwards sides of origin.

Hence Y min & Y max = (0 - 400, 0 + 400) = ( -400, + 400) respectively.

Answer: 15

Step-by-step explanation: To evaluate an expression, we plug the value of the variable into the expression and simplify.

Since we have 7 - 2x and x is -4, we have 7 - 2(-4).

Simplifying from here, 2(-4) is -8 so we have 7 - (-8).

Now, remember that a a minus sign followed by a

negative sign turns the two signs into a plus sign.

So 7 - (-8) can be thought of as 7 + (+8) which is 15.
