I’ll give you 20 points if you help me

If we have a 90 in class but get a zero that is worth 15 points, 0 will be that grade.

I know it takes 3 '15' to get 'C' from 0. Knowing this, getting zero is not recommended.

Here is the information we need to know to answer the question correctly.

For example:

3 allocations of 100 each .

3 x 15 = 45

45 / 3 = 15%

But now 0:

The same 3 allocations of 15 each AND these 0...

3 x 15 = 45

45 / 4 = 11.25%  which is a 25 point drop at zero.

Let's say we have 10 allocations of 15 each...

10 x 15 = 150

150 / 10 = 15%

But we have 15 allocations of the same Questions each, which is 0.

What is an optimal solution?

An acceptable solution where the objective function reaches its highest (or minimum) value, such as the most profit or the lowest cost, is referred to as an optimal solution. When there are no other practical solutions with superior objective function values, the solution is said to be globally optimal.

Here, we have

The global optimum point may be superior to nearby points, but the local optimum point is the true optimal solution to a nonlinear programming problem.

Because when own linear model is solved this solution is merely local optimum.

The solver should consider that other local optimum Amy does not exist with better object values. The globally optimal solution is one where there are no feasible solutions with a better objective function.

However many nonlinear problems are non-convex and are likely to have multiple locally optimal solutions. The local optimum point is the true optimal solution for the nonlinear programming model.

Hence, the given statement to this question is true.

What is an angle?

When two lines come together at a common point, an angle is created. They are expressed as a number of degrees, denoted by the symbol °. Acute, right, obtuse, and reflex angles are the other three significant types of angles.

Given that ∠ADB and ∠BDC are supplementary angle.

∠ADB = (2x - 15)° and ∠BDC = 11x°.

Two angles are supplementary angle, if their sum is equal to 180°.

Therefore,

∠ADB + ∠BDC = 180°

Putting the value of ∠ADB and ∠BDC:

(2x - 15)° + 11x° = 180°

2x - 15 + 11x = 180

Combine like terms:

(2x + 11x) -15 =180

13x - 15 =180

Add 15 with both sides:

13x = 180 +15

13x = 195

Divide both sides by 13:

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

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

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as N

The value of N is given by

The product of -1.8 and 3 more than a number as the same as 1 / 10

So , substituting the values in the equation , we get

product of -1.8 and 3 more than a number

And , -1.8 x ( N + 3 ) is equal to 1/10

So , the equation will be

-1.8 x ( N + 3 ) = 1/10

Divide both sides of the equation by -1.8 , we get

N + 3 = -1/18

Subtracting 3 on both sides of the equation , we get

N = -1/18 - 3

On simplifying the equation , we get

Answer:

not a solution

Step-by-step explanation:

to determine if (- 10, 5 ) is a solution to the system of inequalities.

substitute the coordinates of the point into the left side of both inequalities and compare the result to the right side.

Both inequalities must be true for the point to be a solution.

2x - y = 2(- 10) - 5 = - 20 - 5 = - 25 < - 7 ← true

x - y = - 10 - 5 = - 15 < - 6 ← false

since both inequalities are not true then (- 10, 5 ) is not a solution

A: he percent of respondents who do not like hamburgers and burritos both = 16.09 %

B: Marginal relative frequency of all customers that like hamburgers= 0.65

C: Those who like Hamburgers but not burritos.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

                         Like Hamburgers ↓  Does Not Like Hamburgers↓    Total↓

Likes burritos →                 39                           38                                   77

Does not like burritos →    95                           33                                 128

Total →                                134                           71                                 205

So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 77-38= 39 like Hamburgers.

A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining  128 - 95 = 33 do not like Hamburgers.

A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.

Part A: The percent of respondents who do not like hamburgers and burritos both

There are 33 such respondents.  

Hence, percentage = (033/205) *100 = 16.09 %

Part B: Marginal relative frequency of all customers that like hamburgers

It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents

Hence, ratio  134/205 = 0.65

Part C: The data point that has the strongest association of its two factors.

For this, we need to find the ratio of all the four data with the total.

Those who like Hamburgers and burritos = 39/134 = 0.29

Those who like Hamburgers but not burritos = 95/134 = 0.71

Those who like burritos but not Hamburgers = 38/71 = 0.53

Those who do not like burritos or Hamburgers = 33/71 = 0.47

So, the answer is those who like Hamburgers but not burritos.

Answer:

Each pen is 2.20

Step-by-step explanation:

We first need to find the total cost of the pens

20.50 - 2.90 = 17.60

Now we can divide by the number of pens purchased.

17.60 / 8

2.20

Each pen is 2.20

Answer:

$ 2.20

Step-by-step explanation:

First, let us find the total cost of pens.

$ 20.50 - $ 2.90 = $ 17.6

And now let us find the cost per pen.

For that, let the cost of a pen be x.

Number of pens Cost

8 $ 17.6

1 x

Use cross multiplication and find the value of x.

8x = 1 × 17.6

8x = 17.6

Divide both sides by 8.

x = $ 2.2

Therefore,

Cost of a pen is $ 2.20

The fact that the sum of angles A and B are supplementary to angle C is not needed to prove triangles are similar.

Triangle - what is it?

A polygon with three edges and three vertices is called a triangle. A triangle's total number of angles equals 180 degrees. In mathematics -

∠x + ∠y + ∠z = 180°

A triangle's two sides added together are greater than its third side. In mathematics -

a + b > c

There are numerous varieties of triangles, including:

Equilateral, scalene, isosceles, and other triangles are used.

Two overlapping triangles are shown.

Angle C is supplementary to the sum of angles A and B, which can be expressed as follows:

∠C = 180 - (∠A + ∠B)

Therefore, it is not necessary to demonstrate that triangles are comparable in order to show that the sum of angles A and B is added to angle C.

Assuming simple interest rate, to reach the account value of 28500 dollars, it needs 27.2 years.

Assuming simple interest rate, the formula for the future value is:

FV = PV (1 + r x n)

Where:

PV = present value

r = interest rate per period

n = number of periods

Parameters given in the problem,

r = 8.5% = 0.085

PV = 8600

FV = 28500

Plug these parameters into the formula:

28500 = 8600 (1 + 0.085 x n)

1 + 0.085 x n = 3.313

Answer: the number of hours a student should spend on their homework to expect a score of 89 on the quiz

Step-by-step explanation:

The answer is true. The curve of t-distribution has thicker tails than the curve of the standard normal distribution.

The t-distribution is also called as Student's t-distribution which is a type of probability distribution with a bell shape which is similar to  normal distribution but has thicker tails. It is used to estimate population parameters when sample sizes are small or variances are unknown. T-distributions have a higher probability of extreme values more than normal distributions which results in thicker tails.

Tail thickness is determined by a t-distribution parameter called degrees of freedom, with lower values resulting in heavier tails and higher values resulting in the t-distribution resembles standard normal distribution with a  standard deviation of 1and mean of 0.

Thus, t-distribution has thicker tails than the normal distribution.
