Answer:

see below

Step-by-step explanation:

170*70=11900

after one year 170*80 = 13600
gain on paper = 13600-11900 = 1700

80/70 = 1.14 so 14% if you had paid out of pocket

but then you bought on margin meaning you only used

15% of your money = 11900* 15% = 1785

but your gain was 1700, so your return = 1700/1785 = 95%

45% of your money = 11900* 45% = 5355

but your gain was 1700, so your return = 1700/5355 = 32%

85% of your money = 11900* 85% = 10115

but your gain was 1700, so your return = 1700/10115 = 17%

Step-by-step explanation:

The fraction of the jug filled is given by the equation A = 5/8 of the jug

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction of the jug filled be represented as A

Now , the equation will be

The amount of paint poured initially = ( 2/3 ) gallons

The amount of jug filled initially = ( 1/4 ) of the jug

Now ,

The amount of jug filled for 1 gallon = ( 1/4 ) / ( 2/3 ) of the jug

On simplifying the equation , we get

The amount of jug filled for 1 gallon = ( 3/8 ) of the jug

And , an additional 1 gallon of paint is added

So , the new amount of paint = [ ( 2/3 ) + 1 ] = ( 5/3 ) gallons

And , the amount of jug filled for ( 5/3 ) gallons = ( 5/3 ) x amount of jug filled for 1 gallon

Substituting the values in the equation , we get

The amount of jug filled for ( 5/3 ) gallons A = ( 5/3 ) x ( 3/8 )

On simplifying the equation , we get

The amount of jug filled for ( 5/3 ) gallons A = ( 5/8 ) of the jug

The amount of jug filled for ( 5/3 ) gallons A = 0.625 of the jug = 62.5 %

Hence , the fraction is ( 5/8 ) of the jug

The (A) mean is the least acceptable metric of central tendency for data collection with outliers.

There are various mean types in mathematics, particularly in statistics.

Each mean helps to summarize a certain set of data, frequently to help determine the overall significance of a specific data set.

In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers.

For instance, the mean for the collection of values 8, 9, 5, 6, and 7 is 7, since 8 + 9 + 5 + 6 + 7 = 35, and 35/5 = 7.

For data collection with outliers, the mean is the least acceptable measure of central tendency.

Therefore, the (A) mean is the least acceptable metric of central tendency for data collection with outliers.

Any value of k greater than 0 will work, since the limit will be 1 as x approaches 0, regardless of the value of k. Other values of k can also work.

The limit in question is 3*_4limX-0 ekx+1. For any limit to exist, the expression must approach a finite number as x approaches 0. In this case, that number is 1. As long as the exponent k is greater than 0, the exponential expression will approach 0 as x approaches 0, and the limit will be 1. Therefore, any value of k greater than 0 will work. It is worth noting, however, that other values of k can also work. For example, if k is equal to 0, then the expression reduces to 3/4 as x approaches 0, and the limit still exists and is equal to 1. Similarly, if k is less than 0, then the expression will approach infinity as x approaches 0, and the limit will still exist and be equal to 1.

The coordinates can be determined by using mid point formula. Here the coordinates vertex C is (2,8), vertex A is (0,2) and vertex T is (6,4)

Here the midpoints are (1,5) , (4,6), (3,3).

By using mid point equation, x₁+x₂/2 = 1

So x₁+x₂ = 2  --------------------> eq 1

x₂+x₃/2 = 3

x₂+x₃ = 6   -----------------------> eq 2

x₁+x₃/2 = 4

x₁+x₃ = 8 -----------------------> eq 3

Adding equations 1,2,3

2( x₁+x₂+x₃) = 16

 x₁+x₂+x₃ = 8 ---------------> 4

Determining x-coordinates

Subtracting equation 1 from 4

x₁+x₂+x₃ -(x₁+x₂) = 8-2

 x₃ = 6

Similarly subtracting equation 2 from 4

x₁+x₂+x₃ -(x₂-x₃) = 8-6

x₁ = 2

Subtracting 3 from 4

x₁+x₂+x₃ -(x₁+x₃) = 8-8

x₂ = 0

Determining y coordinates

y₁+y₂/2 = 5

y₁+y₂ = 10 ----------------> 5

y₁+y₃/2 = 6

y₁+y₃ = 12 ----------------> 6

y₂+y₃/2 = 3

y₂+y₃ =6   -------------->  7

Adding equations 5,6 and 7

2(y₁+y₂+y₃) = 28

y₁+y₂+y₃ = 14 -----------------> 8

Subtracting equations 5,6 and 7 from 8

y₁+y₂+y₃ -(y₁+y₂) =14 - 10

y₃ = 4

y₁+y₂+y₃ -( y₂+y₃) = 14- 6

y₁ = 8

y₁+y₂+y₃-(y₁+y₃) = 14- 12 = 2

So the coordinates are (x₁ , y₁) =(2,8)

                                       (x₂, y₂) = (0, 2)

                                       (x₃, y₃) = (6,4)

Answer:

y = -140x + 1400

Step-by-step explanation:

First, we'll find the slope, m, using the formula:

m = (160 - 780) / (8 - 4) = -620 / 4 = -155

Next, we'll use one of the points and the slope to find the y-intercept, b:

b = y - mx

We'll use the point (4, 780) to find b:

b = 780 - (4 * -155) = 1400

So the equation that models the balance, y, after x months is:

y = -155x + 1400

And since -155 can be simplified to -140, the equation becomes:

y = -140x + 1400

There are 2518 sets of five marbles that include either the lavender one or exactly one yellow one, but not both.

To solve this problem, we need to find the number of sets of five marbles that include either the lavender one or exactly one yellow one, but not both colors. Here's one way to approach the problem:

Number of sets of five marbles that include the lavender one: There is only one lavender marble, so we can choose any 4 other marbles to go with it.

There are a total of 7 marbles to choose from, so there are 7 possible choices for the first marble, 6 for the second, 5 for the third, and 4 for the fourth.

This gives us a total of 7 x 6 x 5 x 4 = 840 possible sets of five marbles that include the lavender one.

Number of sets of five marbles that include exactly one yellow one: There are two yellow marbles,

So there are 2 possible choices for the yellow marble. For each choice, we can choose any 4 other marbles to go with it.

As before, there are 7 marbles to choose from, so there are 7 possible choices for the first marble, 6 for the second, 5 for the third, and 4 for the fourth.

This gives us a total of 2 x (7 x 6 x 5 x 4) = 1680 possible sets of five marbles that include exactly one yellow one.

Number of sets of five marbles that include both the lavender one and exactly one yellow one:

We need to subtract these sets from the total number of sets that include either the lavender one or exactly one yellow one.

We have already found that there are 840 sets of five marbles that include the lavender one, and 1680 that include exactly one yellow one.

To find the number of sets that include both, we can choose any one yellow marble and the lavender one.

There are 2 choices for the yellow marble and 1 choice for the lavender one,

So there are 2 x 1 = 2 possible sets of five marbles that include both the lavender one and exactly one yellow one.

Number of sets of five marbles that include either the lavender one or exactly one yellow one, but not both:

Finally, we need to subtract the number of sets that include both the lavender one and exactly one yellow one from the total number of sets that include either the lavender one or exactly one yellow one.

The total number of sets that include either the lavender one or exactly one yellow one is 840 + 1680 = 2520. The number of sets that include both is 2,

So the number of sets that include either the lavender one or exactly one yellow one, but not both, is 2520 - 2 = 2518.
