Answer:

$926.45

Step-by-step explanation:

$871.95 x .0625 = $54.50

$871.95 + $54.50 = $926.45

$926.44

Step-by-step explanation:

sales tax = price*sales tax rate

sales tax = $54.49

871.95+54.49 = answer I think

8/9 - 1/3

To subtract these two fractions, first find a common denominator.

The common denominator will be the

least common multiple for the two denominators.

In this case, the least common multiple of 9 and 3 is 9.

So to subtract, a denominator of 9 is needed in each fraction.

8/9 already has 9 in the denominator so it stays the same.

To get a 9 in the denominator of 1/3, multiply top and bottom by 3.

This gives us 3/9.

So we have 8/9 - 3/9 which is 5/9.

Answer:

Five-ninths

Step-by-step explanation:

Since the denominators are different (9 and 3) we need to change one of them.

9 is divisible by 3 therefor we do not need to change Eight-ninths.

3 times 3 = 9, nine becomes the new denominator, but remember, whatever we do to the bottom (denominator), we must also do to the top (numerator).

1 times 3 = 3

Now the equation is 8/9 - 3/9, we must only subtract the numerators. The answer is 5/9.

Answer:

Michaela = h

Michaela's sister = 3h

Answer = 3h

If Michaela has h hair ties and Michaela's sister has triple number of hair ties then the expression which shows the number of hair ties that Michaela's sister has is 3h.

Expression is a combination of number, symbols, variables, coefficients, indeterminants, functions, etc. It is usually not present in equal to form.

We have been given that Michaela has h number of hair ties and Michaela's sister has triple the number of hair ties that Michaela has, so if h is the expression for Michaela then 3h will be the expression for Michaela's sister.

Hence the expression which shows the number of hair ties that Michaela's sister has is 3h.

Hello, we know that

[tex]|x|=\begin{cases}x &\text{if } x \geq 0\\ -x &\text{if } x < 0 \end{cases}[/tex]

And we can write that 12x-5=0 <=> 12x =5 <=> x = 5/12

So,

[tex]|12x-5|=\begin{cases}12x-5 &\text{if } x \geq \dfrac{5}{12}\\\\ -12x+5 &\text{if } x < \dfrac{5}{12}\end{cases}[/tex]

Answer:

segment AD

Step-by-step explanation:

LOD is the far side of the cube.

ABC is the left side.

So the intersection is the vertical EDGE AD, on the far-left.

The two planes ABC and LOD intersect each other at the segment AD.

A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates. These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.

Given that there is a cube made of six sides. The two planes ABC and LOD intersect each other at the line segment AD or AD is the common line between the two planes. LOD is the far side of the cube. ABC is on the left side. So the intersection is the vertical EDGE AD, on the far left.

Therefore, the two planes ABC and LOD intersect each other at the segment AD.

Answer:

This week's batch had the greater ratio of sugar to berries

Step-by-step explanation:

Last week's ratio was 2:18

This week's ratio was 4:30

Now, we can simplify both of these:

Divide last week's by 2:

1:9

Divide this week's by 2:

2:15

1:9 is equivalent to 0.11, and 2:15 is equivalent to 0.13

So, this week's batch had the greater ratio of sugar to berries

The batch with 4 cups of sugar and 30 cups of berries has a greater ratio of sugar to berries and is given by the proportion B = 4/30 = 0.1333

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion equation be represented as A and B

Now , for the last week's batch

Alec used 2 cups of sugar and 18 cups of berries

So , the ratio of sugar to berries is 2 : 18

The proportion is 2 / 18 = 0.1111

Now , for this week's batch

Alec used 4 cups of sugar and 30 cups of berries

So , the ratio of sugar to berries is 4 : 30

So , the proportion is 4 / 30 = 0.1333

Now , the proportion of 4 : 30 is greater than 2 : 18

Hence , this week's batch had a greater proportion

Answer:

h = 10 m

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Area = 100 m²

base = 20 m

therefore,

100 m² = 1/2 * 20 m * h

h = 100 / 10

h = 10 m

The height will be 10 m.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, the area of a triangle is 100 m² and base is 20 m.

The area of a triangle = 1/2xbasexheight

100 = 1/2x20xh

h = 100/10

h = 10

Hence, The height will be 10 m.

Step-by-step explanation:

Immunisation is used to lower the risk factor that may arise due to change in interest rate . For it, cash inflow and cash outflow are matched in terms of their timing . In other words, effective duration of asset and liability are matched with the help of methods like cash flow matching , duration matching etc.

Even lowering of interest  rate in long term may entail risk because it may increase the bond price which may affect the business adversely in some way if bond is kept as liability . It may reduce the price of asset if it is held as asset .

Exact matching is possible only when matching of cash flow is achieved along with its timing . Matching of present value will not serve the purpose .

Macaulay or modified duration can be used to develop an immunization strategy . Both of them calculate the duration of asset and liability with some change in the method of calculation.

x =  -   ------------

                7x

Step-by-step explanation:

N = 2 r t² - 7 r x

solve for x

N = 2 r t² - 7 r x

N + (-2 r t²) = (2 r t²  - 7 r x) + (-2 r t²)

N - 2 r t² = 2 r t² - 7 r x - 2 r t²

N - 2 r t²  - 2 r t² +  2 r t² = - 7 r x

N - 2 r t² = 7 r x

x is 7

Step-by-step explanation:

3x - 5(y + x)^2 = 16

3x - 16 = 5(y + x)^2

(y + x)^2 = 1/5(3x - 16) ------ eqn(I)

4x + 2(y + x)^2 = 30

2(y + x)^2 = 30 - 4x

(y + x)^2 = 1/2(30 - 4x) ------- eqn(II)

Equate eqn (I) & (II)

1/5(3x - 16) = 1/2(30 - 4x)

Multiply both sides by 10

2(3x - 16) = 5(30 - 4x)

Case-Control Calculation Enter only numeric values into the answer line. Place a leading 0 before the decimal and remember to round to two decimal places. Note your answers for the next short essay question. Swine Influenza (SI) is a growing concern at the local Broncoville Health Department in Lawrence, Kansas. You are working for a pharmaceutical company which is developing a human vaccine against SI. You are in charge of testing the vaccine’s effectiveness. You need to determine if one or two doses of vaccine is required to provide immunity. You field test and collect the following information about the vaccine status of persons who did and did not contract SI after getting either one or two doses of vaccine. Develop a 2 x 2 table with the following information: Of the 727 cases of SI, 203 received two doses of vaccine. Of 1,239 controls, 771 received two doses of vaccine for SI. What is the likelihood of contracting SI with only one dose of vaccine?

1. Calculate the incidence of persons with one dose of vaccine for SI

2. Calculate the incidence of persons with two doses of vaccine for SI

3. Calculate the odds ratio of developing SI among those with one dose of vaccine for SI

answer : 1) ≈ 0.53 , (2)  ≈ 0.21,  (3)  ≈ 1.12

Step-by-step explanation:

cases of SI = 727

number of SI cases that received two doses of vaccine = 203

number of SI cases that received one dose of vaccine = 727 -203 = 524

controls = 1239

number of controls that received two doses of vaccine = 771

number of controls that received one dose of vaccine = 1239 - 771 = 468

I) The incidence of persons with one dose of vaccine for SI

= 524 / 992 = 0.528 ≈ 0.53

2) The incidence of persons with two doses of vaccine for SI = 203/974 = 0.208 ≈ 0.21

3) The Odds of SI in one dose group

=  524/468 = 1.119 ≈ 1.12

[tex]V(n) =225000*0.7^n[/tex]

Step-by-step explanation:

In this problem we are expected to model the depreciated value of the machine after some years of purchase (n years)

initial value of the machine is $225,000

after a year it reduces by 30%

Therefore the new value is now 70% of the initial value

[tex]= 225000*0.7= 157,500[/tex]

= $157,500

After another year it reduces by 30%

Hence the new value is

[tex]=225000*0.7^2\\\=225000*0.49\\\\\=110250[/tex]

= $110250

that after n years the value will be
