Answer:

The sample  is calculated by adding the samples and dividing by the number of sample size.

X ± 2.58(6$)/√64

Step-by-step explanation:

Given:

Data were collected  by 64 customers for lunch.

Based on past studies, the population standard deviation is known with =∂= $6

a) At 99% confidence

By using given information,

∂= $6, n= 64,

At 99% confidence, the value of z = 2.58

By using formula of margin error:

ME=za/2 ∂/√n

       = 2.58 $6/√64

        = 15.48/8

       =1.935

b) Find the 99% confidence interval for mean amount spent on lunch?

By using given information:

∂= $6, n= 64,

At 99% confidence, the value of z = 2.58

By using the formula:

X ± z∂/√n

Where x is the sample means, z is the %99 confidence level, which is equal to 2.58

The sample  is calculated by adding the samples and dividing by the number of sample size.

X ± 2.58(6$)/√64

Answer:

1/3

Step-by-step explanation:

2 - 1 is 1

Denominator stays the same

Answer:

1/3

Step-by-step explanation:

when adding and subtracting fractions you need to make sure there is a common denominator (same number on the bottom of the fractions). luckily these fractions already have that so you just add them! when they have a common denominator the number stays the same. so 3+3 in this equals 3 lol

Answer: 1388

Step-by-step explanation:

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + R/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

The amount in the account after 19 years is $1388.

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + R/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $580

R = 4.6%

n = 12 ( compounded monthly)

t = 19 years

Now,

Convert R as a percent to r as a decimal

r = R/100

r = 4.6/100

r = 0.046 rates per year,

Now,

A = P [tex](1 + R/n)^{nt}[/tex]

A = 580 [tex](1 + 0.046)^{12\times19}[/tex]

A = 580 [tex](1.0046)^{228}[/tex]

A = $1,387.64

Rounding to the nearest dollar we get,

A = $1388

Thus,

The amount in the account after 19 years is $1388.

Answer:

the answer would be 34

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/2, 2/17

For the denominators (2, 17) the least common multiple (LCM) is 34.

LCM(2, 17)

Therefore, the least common denominator (LCD) is 34.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/2 = 1/2 × 17/17 = 17/34

2/17 = 2/17 × 2/2 = 4/34

Area of A = [tex]8 \cdot 2x = 16x[/tex]

Area of B = [tex]8 \cdot x = 8x[/tex]

Area of shape = Area of A + Area of B = [tex]16x + 8x[/tex]

The area of the figure can be given from the expression 24x

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

The entire figure can be split into 2 figures of different length and width

Let the top figure be A and the bottom figure be B

So , Area of the figure = Area of A + Area of B

Now , the Length of B = 16

Width of B = x

Area of B = Length of B x Width of B

So , Area of B = 16x

And from figure , we can conclude that

Length of A = 16 - 8

                          = 8

And Width of B = x

Area of B = Length of B x Width of B

So , Area of B = 8x

Therefore , total area of figure = Area of A + Area of B

                                                   = 16x + 8x

                                                   = 24x

Hence , the area of the figure is 24x

[tex]G = (2,6)[/tex]

Step-by-step explanation:

See Attachment for Complete Question

From the attachment, we can see that F is plotted at

[tex]F = (5,4)[/tex]

On the x axis, G is 3 units to the left;

And on the y axis, G is 2 units above

So, the coordinates of G is calculated as:

[tex]G = (5-3,4+2)[/tex]

[tex]G = (2,6)[/tex]

Hence:

Answer:

y = 16

Step-by-step explanation:

Given

40 = 2.5y ( isolate y by dividing both sides by 2.5 )

16 = y

========================================================

Work Shown:

I'm assuming your teacher is applying the restriction that both 'a' and 'b' are positive integers.

L = LCM(a,b) = LCM of 'a' and 'b' = 9

G = GCD(a,b) = GCD of 'a' and 'b' = 378

L = (a*b)/G .... this shows how the LCM and GCD are connected

G*L = a*b

a*b = G*L

a*b = 9*378

ab = 3402

b = 3402/a

-------------------

a+b = a + (3402/a)

a+b = (a^2)/a + (3402/a)

a+b = (a^2+3402)/a

Replace 'a+b' with y. Replace every copy of 'a' with x. We get this equation

y = (x^2+3402)/x

Use a calculator or calculus to find that the lowest point occurs at the approximate location (x,y) = (58.3266662412, 116.6533325713)

Check out the diagram below. The graph was made with GeoGebra.

At this point we would stop since we found the lowest y value; however, keep in mind that 'a' and 'b' are integers. There is no way to have a+b add to the non-integer result 116.6533325713

---------------------

What we must do is look at a table of values where we see what integer x values lead to y being an integer as well. Those pairs are

x = 54, y = 117

x = 63, y = 117

Which are highlighted in the same diagram as the graph.

I restricted the table so that [tex]50 \le x \le 60[/tex] due to the lowest point found earlier having an x coordinate of roughly 58.3266662412

Based on what the table says, the smallest a+b can be is 117.

Answer:

107.50

Step-by-step explanation:

Given the following :

Midpoint (S)____F

S y 93 95 97 99 101 103 105 107 109 111 f 19 25 38 17 12 10 5 4 4 2

Calculating the mean and standard deviation using a calculator :

The mean(m) of the data above = 98.12

Standard deviation (sd) = 4.02

Proportion = 99% of population

From z table = 2.33

Using :

Zscore =(x - m) / sd

2.33 = (x - 98.12) / 4.02

2.33 * 4.02 = x - 98.12

9.3666 = x - 98.12

9.3666 + 98.12= x

x = 107.4866

X = 107.50
