Peppers are priced 3 for $1.02 . How much would one pepper cost

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 10, 4) and (x₂, y₂ ) = (2, - 5)

m = [tex]\frac{-5-4}{2+10}[/tex] = [tex]\frac{-9}{12}[/tex] = - [tex]\frac{3}{4}[/tex], thus

y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the line

To find c substitute either of the 2 given points into the partial equation

Using (2, - 5), then

- 5 = - [tex]\frac{3}{2}[/tex] + c ⇒ c = - 5 + [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

y = - [tex]\frac{3}{4}[/tex] x - [tex]\frac{7}{2}[/tex] ← equation of line

Answer:

1.75*10 to the power of 5

Step-by-step explanation:

start by moving the decimal over until only one number is in front of the decimal. this is because in scientific notation a number can't be higher than 9.

check how many places you move the decimal over (5). 1.75000 needs to be simplified (since that's the point of scientific notation) and can be simplified to 1.75.

the answer is 1.75 multiplied by ten to the power of digits the decimal moved (5) so the answer is 1.75*10 to the power of 5

175,000 in scientific notation is 1.75 × [tex]10^5[/tex].

To express the number 175,000 in scientific notation, follow these steps:

Move the decimal point in the number to the position after the first non-zero digit. For 175,000, this is 1.75.

Count the number of places the decimal point has moved to determine the exponent of 10. In this case, the decimal point moves 5 places to the left.

Combine the number obtained in the first step with the power of 10 determined in the second step. Thus, 175,000 in scientific notation is 1.75 × [tex]10^5[/tex].

This provides a concise representation of the number.

Answer:

x=17

Step-by-step explanation:

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

In the triangle ABC

m∠A+m∠B+m∠C=180°

substitute the values and solve for m∠C

4x+49°+m∠C=180°

m∠C=180°-49°-4x

m∠C=131°-4x

In the triangle EDC

m∠E+m∠D+m∠C=180°

we have

m∠E=x

m∠D=100°

m∠C=131°-4x -----> by vertical angles

substitute the values

[tex]x+100\°+(131\°-4x)=180\°\\-3x+231\°=180\°\\3x=231\°-180\°\\3x=51\°\\x=17[/tex]

The value of x for the given geometric problem is determined to be 17 by using the concept that the sum of the internal angles of a triangle is equal to 180 degrees.

We are looking to find the value of x where two triangles are involved.

First, according to the laws of geometry, the sum of the internal angles of a triangle must be equal to 180 degrees.

So, in triangle ABC, m∠A+m∠B+m∠C=180°.

If we have m∠A = 4x and m∠B = 49°, then by substituting these values, m∠C becomes 180° - (49° + 4x) i.e 131° - 4x.

In the triangle EDC, the summation m∠E + m∠D + m∠C also equals 180°.

If m∠E=x, m∠D=100°, and m∠C=131°-4x, we can form an equation of x + 100 + 131 - 4x = 180 which simplifies to 231 - 3x = 180. Solving this equation gives x = 17.

Answer:

Yes, the total price is proportional to the pounds of oranges she purchased.

Step-by-step explanation:

The price of oranges is $0.78 per pound.

So, the price $0.78 corresponds to one pound, in a way, that is called direct proportionality.

This means that the price will increase or decrease in a constant ratio, depending on the amount of pounds purchased.

For example:

If she buys 1 pound of oranges she will pay $0.78. Ratio is 0.78 (0.78/1)

If she buys 2 pounds of oranges she will pay $1.56. Ratio is 0.78 (1.56/2)

If she buys 2.5 pounds of oranges she will pay $1.95. Ratio is 0.78 (1.95/2.5)

If she buys 3 pounds of oranges she will pay $2.34. Ratio is 0.78(2.34/3)

We can see that ratio is constant, then we can say that the total price she pays is proportional to the pounds of oranged purchased.

Answer:

[tex]45\times 32 \neq (45\times 3) + (45\times 2)[/tex]

Step-by-step explanation:

First we will evaluate the value of the expressions.

[tex]45\times 32 = 1440[/tex]

[tex](45\times 3) + (45\times 2) = 225[/tex]

Hence, Saleem made an error in the evaluation of product of 45 and 32.

Saleem did a mistake in placing the values that is in 32, 3 is at ten's place so he should have multiplied 45 by 30 instead of 3.

The product can be evaluated in a correct manner as:

[tex](45\times 30) + (45\times 2) = 1350 + 90 = 1440[/tex]

Answer:

y = -6

Step-by-step explanation:

The y intercept is when x equals 0 , and as you can see in the coordinate, the x is zero so the y is -6. Since the slope is undefined, the answer is y=-6. I know that seems confusing, but when the slope is undefined, it just means that it is a straight line.

Answer:

See below.

Step-by-step explanation:

There is an infinite number of values of x that make each answer true. The problem is asking "for which value" with value in the singular, so I thought it was asking to choose one answer from several, and only one was correct.

1a.

Any number between 8 and 9 is correct.

Examples: 8.1, 8.01, 8.2, 8.3, 8.4, 8.9, 8.95, etc.

As I wrote above, there is an infinite number of correct answers.

1b.

Examples: 8.91, 8.92, 8.93, 8.99, 8.905, 8.97, etc.

Answer:

Assuming that inequalities are a valid answer for this question:

1a. 8 < x < 9

1b. 8.9 < x < 9.1

Step-by-step explanation:

Really, there's no exact answer. For example, on 1a, it could be 8.1, 8.11, 8.2, 8.99999, etc. Inequalities are used to denote the fact that the x value can be anywhere between two values. In 1a, x is between 8 and 9, and in 2a, x is between 8.9 and 9.1.

Answer:

B) The sum of the squared residuals

Step-by-step explanation:

Least Square Regression Line is drawn through a bivariate data(Data in two variables) plotted on a graph to explain the relation between the explanatory variable(x) and the response variable(y).

Not all the points will lie on the Least Square Regression Line in all cases. Some points will be above line and some points will be below the line. The vertical distance between the points and the line is known as residual. Since, some points are above the line and some are below, the sum of residuals is always zero for a Least Square Regression Line.

Since, we want to minimize the overall error(residual) so that our line is as close to the points as possible, considering the sum of residuals wont be helpful as it will always be zero. So we square the residuals first and them sum them. This always gives a positive value. The Least Square Regression Line minimizes this sum of residuals and the result is a line of Best Fit for the bivariate data.

Therefore, option B gives the correct answer.

The only correct option that is minimized by the least squares regression line is;

Option B; the sum of the squared residuals.

We want to find the correct option that minimizes the line. Let's look at the options ;

Option A; This statement is not correct because If you do a summation of the residuals, you would get a value of 0.

Option B; Since error needs to be minimized so that the line is a close to the points as possible and as seen above that the sum of the residuals is zero. Then before we sum them, we need to first of all square the residuals which will always give a positive value. Thus, since the Least Square Regression Line minimizes the sum of residuals, then this option is correct.

Option C; This option is wrong because the sum of the absolute values of the residuals is not a method for in creation of least squares regression line

Option D; This option is wrong because the influence of outliers has nothing to do with the topic in question.

Option E; This option is wrong too because slope has nothing to do with the topic in question.

Answer: Adult tickets = 123

              Student tickets = 235

Step-by-step explanation:

Let x represent the number of adult tickets sold and

let y represent the number of student tickets sold

Then create two equations: Quantity & Cost

Cost:    3.25x + 1.50y = 752.25

Qty:           x   +        y =  358

I am going to solve the system using the substitution method.

You can also solve using the elimination method.

Since x + y = 358

then        y = 358 - x

Substitute y in the Cost equation with 358 - x    and solve for x

3.25x + 1.50(358 - x) = 752.25

3.25x  + 537  - 1.50x = 752.25

1.75x    + 537             = 752.25

1.75x                          = 215.25

      x                          = 123

Now substitute x with 123 into the Quantity equation to solve for y

 x  +  y = 358

123 + y = 358

         y = 235

The required measure of the angle x and y is 45° and 109° respectively.

A triangle with two sides and two congruent angles is called an isosceles triangle.

Here,
A)

triangle is isosceles, so the two angles will be equal, and the sum of the angles in the triangle is 90°.
2x + x + x = 180
4x = 180
x = 180 / 4

x = 45

Similarly,
(B)
Some of the remote interior angles is equal to the remote exterior angle,
71 + (180 - 142) = y
y = 71 + 38
y = 109°

Thus, the required measure of the angle x and y is 45° and 109° respectively.

Answer:

y - 1 = 3(x - 2)

y - 1 = 3x - 6

y = 3x - 5

Answer:

The point slope form of the line is y-1=3(x-2).

Step-by-step explanation:

If a line passes through a points [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is

[tex]y-y_1=m(x-x_1)[/tex]              .... (1)

where, m is slope.

It is given that the slope of a line is 3 and it passes through the point (2,1).

Substitute m=3, [tex]x_1=2\text{ and } y_1=1[/tex] in equation (1), to find the point slope form of the line.

[tex]y-(1)=(3)(x-(2))[/tex]

[tex]y-1=3(x-2)[/tex]

Therefore the point slope form of the line is y-1=3(x-2).

You want to keep the variable on the left and number on right.

So, we need to get rid of 9 and -4y. Let's start with 9.

8y=-16

Finally, divide both sides by 8 to get y=-?.

8y/8=-16/8

The expression is (80w+300)

Step-by-step explanation:

Let

y ----> the total amount of money in both accounts

s ----> the  amount of money in saving account

c ----> the amount of money in checking account

w ----> the number of weeks

we know that

saving account

s=50w+200 -----> equation A

checking account

c=30w+100 ----> equation B

To find out the total amount of money in both accounts, sum equation A and equation B

y=s+c

substitute

y=(50w+200)+(30w+100)

y=(50w+30w)+(200+100)

y=80w+300

therefore

The expression is (80w+300)

Final answer:

To find the ratio of nonwinners in group A to nonwinners in group B, subtract the number of winners from the total number of people in each group. The ratio of nonwinners in group A to nonwinners in group B is therefore 156:319.

Explanation:

To find the ratio of nonwinners in group A to nonwinners in group B, we need to determine the number of winners in each group and subtract that from the total number of people in each group to find the nonwinners.

In group A, three-fifths of the 390 people will win fuel cards, which is equal to (3/5) * 390 = 234 people winning cards. So, the number of nonwinners in group A is 390 - 234 = 156.

In group B, the same number of fuel cards will be given out, but there are 553 people in that group. So, the number of nonwinners in group B is 553 - 234 = 319.

The ratio of nonwinners in group A to nonwinners in group B is therefore 156:319.
