ANS:2113

Answer:

the sample should be 237

Step-by-step explanation:

The computation of the large the sample be used is shown below:

Given that

Standard deviation = 0.09 ounces

margin of error = 0.011

For 94% confidence interval, the z value be 1.88

As we know that

Margin of error = ((z score × standard deviation) ÷ (Sample size))^2

0.011 = (1.88 × 0.09) ÷ (Sample size))^2

0.011 = 0.1692 ÷ (Sample size))^2

So, the sample size be

= 15.38^2

= 236.60

Hence, the sample should be 237

Domain:  (-∞, 2] U (3, 6]
Range: (-∞ , 1] U (-1, 4]

Step-by-step explanation:

This is a piecewise function. It has a discontinuity at x=2 and x = 3

The domain of a piecewise function is the union of the domains of each piece of the function. Similarly the range for a piecewise function is the union of the ranges for each piece of the function

Looking at the graph, we can see two subdomains. When x ≤ 2 , we have one subdomain and when x > 3 there is another subdomain. We state this as
D = - ∞ < x  ≤ 2 or 3 < x ≤ 6
In interval notation we represent this as

D =  (-∞, 2] U (3, 6]

The nature of the brackets is important a [ or ] bracket means that the value to which it is attached is included whereas an open bracket, (    or     ) means that value is not included

For example,  (-∞, 2] means that everything below x = 2 to -∞ is part of the domain but it does not include -∞; since at -∞, a function is not defined. However it does include 2 in the domain as can be seen by the closed bracket on the right

The other subdomain is for x > 3 (note: a filled circle means the value is included, an empty circle denotes the value is excluded)

The second subdomain is
3 < x ≤ 6
In interval notation, it is (3, 6]

So the total domain is the union of the two intervals

The range is also discontinuous and there are two distinct ranges. The range is nothing but all the set of values generated by the function. So we look at all possible values for y that the function produces

The Range of this function is  -∞ < f(x) ≤ 1 or -1 < f(x) ≤ -4
In interval notation this is
R = (-∞ , 1] U (-1, 4]

Step-by-step explanation:

option 3 is correct

If you see marginal cost increasing in a graph, this implies that; b. the additional cost incurred in producing one more unit of output is decreasing.

The marginal cost is the change in total production cost that comes from making or producing one additional unit.

When marginal product is rising, the marginal cost of producing another unit of output is declining and when marginal product is falling marginal cost is rising. Thus, Option A and D are not correct.

Option C is wrong because Marginal cost helps to increase efficiency in  production.

Thus, option B is the correct answer.

Answer:

the correct ans should be 88/15

Step-by-step explanation:

since, y is directly proportional to x then,

y=kx where k=proportionality constant

when y=22/5 and x=3/5

or,22/5=k*3/5

or,22/5*5/3=k

•°•k=22/3

now, when x=4/5

we know,

y=kx

or,y=22/3*4/5

•°•y=88/15

Answer:

I believe the answer is A

Step-by-step explanation:

Since when translating down it moves the Y variable and not the X and when reflecting it will turn negative X (-3) into positive 3

Answer:

Margret need to get 4 boxes of cookies.

Step-by-step explanation:

Total friends = 3

Cookies each friend will get = 8

Each box has cookies = 6 cookies

How many boxes does Margret need to get?

Total cookies will be= Total friends x Cookies each friend will get

Total cookies will be= 3 x 8 = 24

If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes

Number of boxes = Total cookies/ number of cookies in one box

Number of boxes = 24/6

Number of boxes  = 4

So, Margret need to get 4 boxes of cookies.

2*2 - 1 = 4 - 1 = 3

Step-by-step explanation:

7 - x    If x=2

7 - 2 = 5

11 - 3x   If x=2

11 - 3*2 = 11 - 6 = 5

2x -1   If x=2

2*2 - 1 = 4 - 1 = 3

4x - 3    If x=2

4*2 - 3 = 8 - 3 = 5

The base ten numbers to base six for the following is

1. 12 (base 10) =20(base 6)

2.31 (base 10) =51(base 6)

3. 41 (base 10) =105(base 6)

The procedure to find the base ten number to base six

We have to divide the number 12 repeatedly by 6 until the quotient becomes 0.

When 12 is divided by 6 the quotient is 2 and the remainder is 0.

When 2 is divided by 6 the quotient is 0 and the remainder is 2.

Now, Write the remainder from top to bottom.

We get [tex]12_{10} =20_{6}[/tex]

Similarly we do, 31 and 41

When 31 is divided by 6 the quotient is 5 and the remainder is 1.

When 5 is divided by 6 the quotient is 0 and the remainder is 5.

Now, Write the remainder from top to bottom.

We get [tex]31_{10} =51_{6}[/tex]

When 41 is divided by 6 the quotient is 6 and the remainder is 5.

When 6 is divided by 6 the quotient is 1 and the remainder is 0.

When 1 is divided by 6 the quotient is 0 and the remainder is 1.

Now, Write the remainder from top to bottom.

We get [tex]41_{10} =105_{6}[/tex]

Therefore, The base ten numbers to base six for the following is

1. 12 (base 10) =20(base 6)

2.31 (base 10) =51(base 6)

3. 41 (base 10) =105(base 6)

Step-by-step explanation:

In the graph of the function, between the interval (-4, 4), there are 4 values of x for which the given function is not differentiable.

The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.

here,
The function from observation seems to be a discontinuous function,
And the function is not differentiable at x = -1, 0, 1, and 3.
So there are 4 points in the interval (-4, 4) where the function is not differentiable.

Step-by-step explanation:

The expressions represent the cost, in dollars, for 4 people to go horseback riding for 3 hours each is  4(3x + 2).

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The total cost to go horseback riding is a dollar per hour plus a $2 fee for renting a helmet.

Let, The number of hours is represented by 'x'.

Therefore, The cost of riding with a helmet is,

= x + 2.

By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.

In this question we find to two line segments that are collinear to each other. Each line is represented by a linear functions, whose length equations are:

AB = 4 · x + 17             (1)

AC = 96 + 2 · x            (2)

AB + BC = AC  

BC = AC - AB               (3)

Then, by (1) and (2) on (3):

BC = (96 + 2 · x) - (4 · x + 17)

BC = 79 - 2 · x

By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.

After a quick investigation, we conclude that the statement has typing mistakes, correct form is shown below:

If AB = 4 · x + 17 and AC = 96 + 2 · x, then find the expression of BC.
