Alejandro has a computer support business. He estimates that the cost to run his business can be represented by X = 48 x + 500, where x is the number of customers. He also estimates that his income can be represented by R = 65 x - 145. How many customers he will need in order to break even?

Answers

Answer 1

The number of customers Alejandro will need in order to break even is 38 customers.

How to find the number of customers to break even?

Given data:

Cost of business = 48 x + 500

Income = R = 65 x - 145

Let x is the number of customers.

Income equation  

R= 65x- 145

Substitute 48x + 500  for y

48x + 500 = 65x -145

Substract 48x from both side

500 = 17x - 145

Add 145 to each side

645 = 17x

Divide both side by 17x

x =645 /17

x = 37.9

x = 38 customers (Approximately)

Therefore the number of customers is 38 customers.

The formula for monthly payment is a is equal to p into or divided by 12 into 1 plus or divided by 12 points the whole power and whole divided by 1 plus r divided by 12 points.The whole power n minus 1 in this formula, p is the lown amount and r is the well interest rate and n is the number of payments here. We have the number of years is 3, so the number of payments will be 36 points. Then, by this formula we have the monthly payment: a is equal to 8700 into 0.0231, divided by 12 into 0.0231 divided by 12 plus 1. The whole power 36 whole divided by 0.0231, divided by 12 plus 1, the whole power 36 minus 1, and it will be equal to 250.32 dollars. Therefore, the monthly payment is equal to 250.32 dollars.

Right triangle... One leg of a right triangle is 4 centimeters longer than the other leg. If the area of the triangle is 6 square centimeters, then what are the lengths of the legs?

Answers

Answer:

2 cm and 6 cm

Step-by-step explanation:

x = first leg

y = second leg


y = 4 + x

xy/2 = 6


y = 4 + x

xy = 12


x(4+x) = 12

x²+4x - 12 = 0

(x+6)(x-2) = 0

x = -6 (impossible because a length can’t be negative)

x = 2 cm


y = 2 + 4 = 6 cm

Answers

The sample proportion of persons with credit card debts of further than $2,000 has a distribution that is roughly normal;

μ = 0.27 and σ = 0.022.

Explain the term random sample?A straightforward random sample, where each participant has an equal chance of being selected, selects a tiny, random piece of the total population for the purpose the full data set.

According to a research conducted in one town, the percentage of persons living there had credit card debt of at least $2,000:

p = 27% = 0.27.

An adult sample from the entire city was gathered: n = 400 adults.

The following two requirements should be used to determine the whether sample is adequate before obtaining a sampling distribution of the probability value p:

np ≥ 10

       400 x 0.27  = 108

       108 ≥ 10

And,

n(1 - p) ≥ 10

      400(1 - 0.27)  ≥ 10

      292  ≥ 10

We know that the as being p is nearly normally distributed the by suing  "Central limit theorem."

Mean M; μ = Pstandard deviation σ = √(p(1 - p)/n.

Mean of a sample proportion

μ = P = 0.27

The standard deviation's sample proportion P:

σ = √(p(1 - p)/n

σ = √(0.27(1 - 0.27)/400

σ = 0.022

Since the sample proportion of persons with credit card debts of further than $2,000 has a distribution that is roughly normal;

μ = 0.27 and σ = 0.022.

As given in the question,

Let us consider cost of a racket is equal to $x

Let us consider cost of a ball is equal to $y.

Equation formed using the given data we have,

3x + 3y = $21.63  ____(1)

3x + 10y = $49.63 ____(2)

Subtract equation (2) from (1) to eliminate x

3x + 10y = $49.63

3x + 3y = $21.63

0x + 7y = $28.00

⇒7y = 28.00

⇒ y = 28 / 7

⇒ y = $4

Substitute the value of y in (1) we get,

3x + 3(4) = 21.63

⇒3x = 21.63 -12

⇒3x = 9.63

⇒ x = $3.21

Therefore, from the given relation the cost of a racket and a ball is equal to $3.21 and $4.00.

Answers

It has been suggested that 4% of all cars on the freeway are going 70 mph. If 4 cars are examined, the probability that at least 1 is going 70 miles per hour is 0.151.

A probability is a numerical representation of the likelihood or possibility that a particular event will occur. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Here, it is said that 4% of all vehicles on the roadway are going more than 70 mph.

P(speed excess of 70 mph) = 0.04. Radar is used to determine the speeds of four random cars. Then, n = 4. Then, X = the number of cars going over 70 mph.

Then, the probability that at least one car is going over 70 mph

= P(x = 1, 2, 3, 4)

The smaller triangle has a right angle and two congruent legs.

Since the legs are congruent, then the opposite angles are also congruent.

The measures of the 3 angles of the right triangle are:

3y, 3y, 90

The sum of the measures of the angles of a triangle is 180°.

3y + 3y + 90 = 180

6y + 90 = 180

6y = 90

y = 15

The larger triangle has 2 congruent sides. The opposite angles are congruent. Each of the congruent angles measures 2x + 3y. The angle above measures 50°.

2x + 3y + 2x + 3y + 50 = 180

4x + 6y + 50 = 180

4x + 6y = 130

We know from above that y = 15.

4x + 6(15) = 130

4x + 90 = 130

In multiple linear regression analysis, the correlation among independent variables is termed multicollinearity i.e. option C.

a) Homoscedasticity: Homoscedasticity, also known as homogeneity of variances, is the presumption that variations in various groups being compared are equivalent or comparable.

b) Linearity: A mathematical relationship (function) that can be graphically represented as a straight line is said to be linear. Proportionality and linearity are closely linked concepts.

c) Multicollinearity: Multiple independent variables in a model that are correlating from a statistical concept known as multicollinearity.

d) Adjusted Coefficient of Determination: The number of variables in a data collection is taken into account when calculating the adjusted coefficient of determination (also known as adjusted R-squared). Additionally, it penalizes you for any points that deviate from the model.

If the surface area of the cylinder is 8cm , then the largest possible volume of such cylinder is (16/3)√(2/3π)  cubic units  .

In the question ,

it is given that ,

the cylinder is an open top ,

given that surface area = 8cm² ,

So , the surface area is = 2πrh + πr²,

8 = 2πrh + πr²

So , h = (8 - πr²)/2πr ,

the volume of the cylinder is (V) = πr²h ,

Substituting the value of h ,

we get ,

V = (8r - πr³)/2,

to find the largest volume , we differentiate it with respect to "r" and equate to 0 ,

we get ,

(8r - πr³)/2 = 0

On Simplifying we get ,

r = √(8/3π) ,

the volume is maximum when r = √(8/3π) ,

So , Volume is = ( 8(√8/3π) - π√(8/3π)³)/2

V = 4(√(8/3π)) - (4/3)(√(8/3π))

V = (8/3)√(8/3π)

V = (16/3)√(2/3π)  cubic units .

Therefore , the maximum volume is (16/3)√(2/3π)  cubic units  .

Coordinate Plane:

A coordinate plane is a two-dimensional plane formed by the intersection of two number lines. One of these number lines is a horizontal number line called the x-axis and the other number line is a vertical number line called the y-axis.

The function rule in slope-intercept form:

The slope-intercept form is one rule to represent linear function rules. f(x)=mx + b is sometimes used. In any scenario, m and b describe the line's overall features. The slope is denoted by m, while the y-intercept is denoted by b.

According to the given figure,

We clearly see that the coordinates of the y-intercept would be (0, 1).

The value of the x-coordinate is 1 when y-coordinate is 3.

Here the line passes through points (0, 1) and (1, 3).

Let the required linear function would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]

x₁ = 0, y₁ = 1

x₂ = 1, y₂ = 3

⇒ y - y₂ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]

⇒ y - 3 = (3 - 1)/(1 - 0 )[x -1]

⇒ y - 3 = (2)[x -1]

⇒ y - 3 = 2x - 2

Explain the term regression line?The assessment of the line that depicts the actual, but unidentified, linear correlation is called a regression line. When the values of the explanatory variable is known, the regression line's equation is applied to predict (as well as estimate) the quantity of the response variable.The linear regression model is predicated on the following premises: Linearity: X and also the mean of Y have a straight line connection. Homoscedasticity: For every value of X, the variance of the residual is the same. Independent of one another: Observations are separate from one another.

Extrapolation refers to using the regression line to produce predictions outside of the data's range.
