The 95% confidence interval for the mean of the population lies between

(17.61, 62.39)

Construct a 95% confidence interval for the mean:

To construct a 95% confidence interval for the mean of the population, we must start with finding the following:

Mean

n=4

Mean=(25+47+32+56)/n

         =(160)/4

         =40

Mean is 40

Standard deviation σ

                             = [tex]\frac{1}{n-1}( \sum x^{2} -n(mean)^{2} )[/tex]

                             = [tex]\frac{1}{3} (6994-4(40)^{2} )[/tex]

                            σ= 14.07

Now, we construct 95% confidence interval CI:

Confidence interval=mean± t-table value*(standard deviation/√n)

Given a t-table value of 3.1824 from z-distribution table, mean=40, n=4, and standard deviation=14.07, we have:

Confidence interval=(40±3.1824(14.07/√4)

                               =(40±22.39)

                               =(40-22.39, 40+22.39)

Confidence interval=(17.61, 62.39)

The opposite of an integer and negative number is a positive integer number. In this case, the opposite of -4 is +4.

The sequence of the decorative fence boards would be 66.48 feet which is the infinite geometric sequence.

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

The first fence board will be 2 feet tall, and each successive fence board will be 25% taller than the previous fence board which is given in the question.

aₙ = arˣ⁻¹   (n ≠ 0)

a₁ = 2

x = (1 +25%) = 125%

n = 10

aₙ = 2 × (125%)

The sum of the terms in a finite or infinite geometric sequence as

Sₙ = a₁ + a₂ + ... +aₙ

= a₁(1 -xⁿ)/(1-x)

= 2(1 -1.25¹⁰)/(1-1.25)

= 2(-8.31)/(-0.25)

a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds Then it would take 32 seconds to fill a carton that measures 4 ft by 4 ft by 6 ft

1) we calculate the volume of the first carton:

volume=length x width x height

volume=3 ft * 3 ft * 1 ft=9 ft³

Therefore:

A machine can fill 9 ft³ in 3 seconds.

2) we calculate the volume of the second carton.

volume=length x width x heigth

volume=4 ft * 4 ft * 6 ft=96 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

9 ft³---------------------3 seconds

96 ft³--------------------      x

x=(96 ft³ * 3 seconds) / 9 ft³=32 seconds.

Answer:

10/9

Step-by-step explanation:

We can calculate f(3) and g(-4)

f(3) = 4*3 - 2 = 12 - 2 =10

and g(-4) = -2 * (-4) + 1 = 8 + 1 = 9

Then it is easy to calculate f(3)/g(-4):

f(3)/g(-4) = 10/9

where we use the values which we calculated before.

⇒In the equation f(x) given f(3) plug in the value 3 in the place of x and simplify

[tex]f(3)=4(3)-2\\f(3)=12-2\\F(3)=10[/tex]

⇒For g(-4) in the place of x plug in -4 in the equation of g

[tex]g(-4)=-2(-4)+1\\g(-4)=8+1\\g(-4)=9[/tex]

Answer:

[tex]h = \dfrac{T - r}{n}\\\\\text{Hourly rate } = \$45\;\;\text{if T = 200, r = 20 and n= 4}[/tex]

Step-by-step explanation:

We have from #14 that
T = r + nh

where T = amount charged, n = hours worked, r = fixed rate and h = hourly rate

Subtract r from both sides:
T - r = r + nh - r

The r terms on RHS of the equation cancel out
T - r = nh

Divide both sides by n:
(T - r)/n = h

Or we can write it as
h = (T - r)/n

If r = 20, , T = 200 and n =4 we get by substitution

h = (200-20)/4

h = 180/4

h = 45

So hourly rate = $45

Answer:

1080 total inches of ribbon. 60 pieces of ribbon can be cut.

Step-by-step explanation:

Firstly, the dressmaker has 15 rolls of ribbon that are 6 feet in length. Multiply those to see how many feet in total, 90. Then multiply this by 12 (there are 12 inches in a foot) to get the amount of total inches: 1080.

This is the answer to the question below the problem.

The remainder of the polynomial 4x³-20x-50 / (x - 3) would be the expression 4x²+20x+52.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

We have to determine the remainder of the quantity 4 x cubed minus 20 x minus 50 end quantity divided by the quantity x minus 3 end quantity.

4x³-20x-50 = (4x³-4x²-16x-50) + (4x²+16x)

Divide both sides by (x - 3) to get

4x³-20x-50 = (4x³-4x²-16x-50)/(x-3)+(4x²+16x)/(x-3)

⇒ 4(x²+4x+12)+(4x²+16x)/(x-3)

The cost of renting the meeting room by the manager for the hours 1,2,3 and 4 defined by the function of (t) = function of (t-1) + 20, given that function of (1) = 100 is 520.

A function can be defined as a mapping whose co-domain is the set of real numbers.

Given the mapping defined as function of (t) = function of (t-1) + 20, for function of (1) = 100

Hence,

.f (2) = function of (2-1) + 20

.f (1) + 20

100 + 20 = 120

.f (3) = function of (3-1) + 20

.f (2) + 20

120 + 20 = 140

f (4) = f (4-1) + 20

.f (3) + 20

140 + 20 = 160

This can be seen in a table as shown above!

We can conclude with the proper mapping of the defined function of (t) = function of (t-1) + 20 for function of (1) = 100 that the total cost for the hours 1,2,3 and 4 for renting the meeting room is 520.

Adam's account balance at the end of the month is 19.13 dollars.

The amount present in Adam's bank account at the beginning of the month is $174.85.

The transactions he wrote are,

58.00

-316.35

102.96

The Transactions which have positive sign are credit amount and the transaction with negative sign are debit amount.

We can write,

The balance at the end of the month = Initial balance present + Credit amount + debit amount

So, balance in Adam's account can be found by simple addition and subtraction,

Balance = 174.85 + 58.00 + 102.96 - 316.38

Balance = 335.81 - 316.68
