Aisha bought 15 apples and oranges for $9. 0. Each orange costs $0. 50, and each apple costs $0. 65. Let x represent the number of oranges and y represent the number of apples. Which system can be used to find the number of apples and oranges aisha bought? x + y = 15. 0. 5 x + 0. 65 y = 9. 00 x = y. 0. 5 x + 0. 65 y = 9. 00 x + y = 9. 0. 5 x + 0. 65 y = 15. 00 x = y. 0. 5 x + 0. 65 y = 15. 0.

Answer:

Step-by-step explanation:

6x^2-2x+1=0

6*6=36

36x-2x+1=0

34x+1=0

subtract 1 on both sides

34x=-1

divide both sides by 34

x=-0.0294117647059

The smallest and largest possible range in the histogram summarizes the percentage of people in each state and the District of Columbia who identify as Hispanic or Latino is 0 - 4.9 and 45 - 49.9 respectively.

As it is clear from the term, percent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.

Given:

The histogram summarizes the percentage of people in each state and the District of Columbia who identify as Hispanic or Latino,

The Hispanic or Latino percentage of the population is shown in the x-axis, whereas the frequency of the population is shown in the y-axis.

Calculate the smallest possible range by considering the graph,

The smallest possible range = 0 - 4.9

Calculate the largest possible range by considering the graph,

The range of the graph is [-4, 11).

A graph is a diagram that depicts the relationship between two variables, usually measured along opposite axes in a pair, is used.

In the given graph,

The value of the x coordinate varies from -8 to 11.

And the values of x shows the domain,

Therefore, domain is (-8, 11).

The y coordinate varies from -4 to 11.

And the values of y coordinate shows the range.

The value of y at 11 is open circle, So it shows open interval.

And at -4 it shows close interval.

The correct interpretation regarding the y-intercept of the least squares regression line is given as follows:

For a car weighing 0 lbs we would expect a fuel efficiency rating of 68.17 mpg.

For a function, the y-intercept represents the value assumed by the output of the function when the input of the function assumes a value of zero.

For the least squares regression line in this problem, the input variable and the output variable are defined as follows:

The y-intercept in this problem has a value of:

68.17.

Meaning that when the weight is of 0 pounds, the fuel efficiency is of 68.17 mpg.

The missing part of the problem is of:

"For this data set, X represents the weight of each car in hundreds of pounds, and Y represents the predicted fuel efficiency of each car in miles per gallon (mpg). Note that 68.17 is reasonable value for the y-intercept of the least squares regression line. Which of the following is the most appropriate interpretation of the y-intercept?"

The roots of the given equation are √5, - √5, 2i, and - 2i      

The values of a variable for which the provided polynomial equals zero are referred to as a polynomial's roots. If n is the root of a polynomial p(x), then p(n) will be equal to zero.

Here we have

x⁴- x²- 20 = 0  

To find the roots of the Equation factorize the given equation

=>  x⁴- x²- 20 = 0    

Let t = x²

=>  t²- t - 20 = 0  

Split the middle term

=> t²- 5t + 4t - 20 = 0  

=> t(t - 5) + 4(t - 5) = 0

=> (t - 5) (t + 4) = 0

=> (t - 5) = 0   and  (t + 4) = 0

Take t - 5 = 0

=>  t = 5  =>  x² = 5

=> x = ±√5          

Take (t + 4) = 0

=> t = - 4 => x² = -4

=> x = ± √- 4                  

=> x = ± 2i         [ ∵ - 1 = i² ]

Therefore,

The roots of the given equation are √5, - √5, 2i, and - 2i

To find the actual size of an item, multiply the scale factor by the size of the item in the drawing

The scale factor is the ratio of the measurement of the new figure to the measurement of the original figure

Here, we are drawing an item on the paper, the size of the object on the paper maybe less than or greater than of original item

The dimensions of the actual item will be equal to the product of scale factor and the dimensions of the item on drawing.

If the scale factor is greater than 1, then the actual size will be greater than drawing, if the scale factor is between 0 to 1, then actual size will be less than drawing

Therefore, to find the actual size multiply the scale factor and size of drawing

Step-by-step explanation:

x-y=-6          (1)..

6x-3y=9       (2)...

First, multiply (1) by 6:

6x-6y=-36

Now subtract the whole eqaution:

 6x-6y=-36

- 6x-3y=9

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

-3y = -45

y=15

Now substitute y into one of the equations:

x-15=-6

x=9

So the answer is x=9, and y=15.

By using the concept of probability, it can be calculated that

Probability that the hand contains exactly two face cards = [tex]\frac{209}{833}[/tex]

What is probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

From the set of five cards, two cards can be chosen in [tex]{5 \choose 2}[/tex] ways = 10 ways

Number of face cards = 12

Number of non face cards = 52 - 12 = 40

Probability that the hand contains exactly two face cards = [tex]{5 \choose 2}\times \frac{12}{52} \times \frac {11}{51} \times \frac{40}{50} \times\frac{39}{49}\times \frac{38}{48}\\[/tex]

The slope of the line which is perpendicular to the given line is (-6/5).

Describe the negative reciprocal.

The negative reciprocal of a number, let's say "n," is "- (1/n).

We are aware of a line's equation in slope intercept form, y = mx + b, as well as the fact that perpendicular lines have slopes that are reciprocal to each other's negative values.

The slope intercept form of the line 15x - 18y = -486 can be expressed as,

-18y = -15x - 486.

- y = (-15/18)x - (486/18).

a. The scatter diagram indicates that the Number of Defective Parts found increases with Line Speed

b. The regression model is Y = 27.5 - 0.3·X

c. When the line speed is 25 feet per minute, the number of expected defective parts is 20 defective parts.

According to the Question:

The give data is presented as follows'

Line Speed;                   20,   20,    30,    30,    40,    40,    50,     50

Number of Defective;   23,    21,     19,     16,     15,     17,     14,       11  

Now,

1. From the scatter diagram there is an apparent correlation between increase line speed and the number of defective parts found.

2. The equation for linear regression by the least squares method is presented as follows;

   Y = a + b·X

Where;

b = N ∑XY - (∑X) (∑Y) / N ∑X² - (∑X)²     -------------------- (1)

and

a = ∑Y - b ∑X / N                          ---------------------------- (2)

Now, after calculation, we have;

∑X = 280, ∑Y = 136, ∑X² = 10,800, ∑XY = 4,460, (∑X)² = 78,400, N = 8

Putting in equation (1) and (2), we get;

b = (8×4460 - 280×136) / (8×10,800 - 78,400) = -0.3

and,

a = (136 - (-0.3)×280)/8 = 27.5

Therefore, we have the linear regression as follows;

                 Y = 27.5 - 0.3·X

Therefore, when the line speed is 25 feet per minute, we have;

Y = 27.5 - 0.3 × 25 = 20

The number of defective parts expected to be found when the line speed is 25 feet per minute, Y = 20 defective parts.

The answer to this Question based on Length is Yes he can easily make a bow with that

What is Length?

Length is a measurement of distance or size. It is the greatest of the three linear dimensions and is often denoted by the letter “L”. Length is commonly used to measure the size of objects, the distance between two points, or the magnitude of a displacement. Length can be measured in a variety of units such as inches, feet, meters, kilometers, or miles. Length is also used to determine the area of a two-dimensional shape, the volume of a three-dimensional shape, and the circumference of a circle. Length is an important concept in mathematics, physics, engineering, and other scientific disciplines. Length can also be used to describe how long something lasts, such as the length of a movie or a song.

we can see that length of henry ribbon that is available is 6 1/4 feet long ribbon which means 25/4 feet ribbon
= 6.25 feet of ribbon

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign.

It is an illustration of inequity.

This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.
