Step-by-step explanation:

To find the slope of thine that passes through these points, use the slope formula. It can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate.”

So we have [tex]\frac{-4 - 5}{-3 - 2}[/tex] and this simplifies to -9/-5 or 9/5.

Remember, a negative divided by a negative is a positive.

Answer:it’s 31.7 cm^2

Step-by-step explanation:

The approximate area of the shaded sector is 31.7 cm² (Option A).

To find the area of the shaded sector, we need to calculate the fraction of the entire circle that the sector represents and then multiply it by the area of the whole circle.

The formula to find the area of a sector is given by:

Area of sector = (θ/360) * π * r²

where θ is the central angle and r is the radius of the circle.

In this case, the radius (r) of the circle is given as 11 cm, and the central angle (θ) is given as 30 degrees.

Let's calculate the area of the shaded sector:

θ = 30 degrees

r = 11 cm

Area of sector = (30/360) * π * 11²

             = (1/12) * π * 121

             = π * 10.0833...

Now, we can approximate the value of π as 3.14:

Area of sector ≈ 3.14 * 10.0833...

             ≈ 31.7 cm²

Therefore, the approximate area of the shaded sector is 31.7 cm².

The correct option from the given choices is A. 31.7 cm².

Answer:

apples have greater discount

Step-by-step explanation:

This is a proportional relation given by;

For apples, it's;

1.59/2.99 = x/100

Where x is the amount the second bag of apples cost in relation to the first, so:

x = 1.59 * 100/2.99

x = 53.18

So,let's now find the discount of the second bag of apples from;

Discount = 100 - 49.83 = 50.17% discount

Similarly, for oranges;

2.59/3.99 = x/100

x = 2.59 * 100/3.99

x = 64.91

So,let's now find the discount of the second bag of oranges from;

Discount = 100 - 64.91 = 35.09%

Since apples have discount of 50.17% and oranges have discount of 35.09%, thus apples have greater discount

Step-by-step explanation:

Subtract 10 from both sides, making the equation 2x=38. X means what your multipying the number by which means it is 38/2 which is 19.

Answer:

x=16

Step-by-step explanation:

The two angles are complementary, which means they must add to 90 degrees.

∠T+∠V=90

We know that ∠T is 2x+10, and ∠V is 48. Therefore, we can substitute thesae values in.

2x+10+48=90

Combine like terms by adding 10 and 48

2x+58=90

Now, we have to solve for x. To do this, we must get x by itself.

Firs,t subtract 58 from both sides

2x+58-58=90-58

2x=32

Divide both sides by 2

2x/2=32/2

x=16

Answer:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Step-by-step explanation:

For this case we can assume that the interest is find an equation for the times per minute with the temperature. So then the independent variable (x) would be the temperature and the dependent (y) the times per minute. We want to adjust a linera model like this one:

[tex] y = mx +b[/tex]

We have the following info given:

[tex] (x_1 = 94 , y_1 = 60)[/tex]

[tex] (x_2 =96 ,y_2 = 66)[/tex]

And we can estimate the slope with the following formula:

[tex] m =\frac{y_2 -y_1}{x_2 -x_1}= \frac{66-60}{96-94}=3[/tex]

And we can find the intercept using the first point given for example:

[tex] 60 = 3*94 +b[/tex]

And solving for b we got:

[tex] b = 60 -282 = -222[/tex]

And the model would be given by:

[tex] y = 3x -222[/tex]

Answer:

Step-by-step explanation:

Let " x "  denotes the temperature in degree Fahrenheit .

Let  " y " denotes the chirp rate per minute .

We have given that at 94 degree Fahrenheit , chirp rate is 64 times per minute and at 96 degree Fahrenheit , it is 118 times per minute .

We write this information in coordinate form ( x,y) .

We have ( x₁ ,y₁)  = ( 94 , 60 )  and  ( x₂ , y₂) = ( 96,66) .

                        y₂   - y ₁                     66  -   60                  6

Slope , m  =  ----------------------  =    ---------------------  =     -----------

                         x₂  - x₁                        96   -  94                   2

          Slope , m =  6/2 = 3 .

Equation of line in slope intercept form is

y = m x + b  where  ' m' is slope and ' b ' is intercept .

Plug value of m  , we get

y = 3 x + b .

To find value of b , we put ( 94 , 60 ) in place of x and y .

Put x = 94 and y = 60 , we get

60 = 3 * 94 + b

60  = 282 + b

60 - 282 =  b

- 222 = b

Thus we get b = - 222 .

So the equation become

y = 3 x - 222 .

Answer:

The answer is..

18 = x (113.4)

x = 95.4

Step-by-step explanation:

The equation 18x = 113.4 represents the sentence " the product of a number, x, and 18 113.4." and the solution of the equation is the value of variable x is 6.29.

Algebra is the estimation of mathematical representations, while logic is the manipulation of those symbols.

The given statement is "the product of a number, x, and 18 is 113.4"

According to the given question, translate the phrase into an algebraic form :

This relationship can be represented by the equation 18x = 113.4.

To find the value of x, we can solve this equation by dividing both sides by 18, which gives us x = 113.4/18 = 6.29.

Thus, the required equation is 18x = 113.4

Answer:

a) One student from the class is chosen at random. What is the probability that the student has a sister?

S/£

b)One of the students who has a brother is chosen at random. What is the probability that this student has a sister?​

BS/£²

Step-by-step explanation:

In the question, we are given the following values:

£ represents 29 students in class = Total number of students in the class.

B represents students who have a brother

S represents students who have a sister

The formula for probability = Number of events ÷ Number of possible outcomes.

a) One student from the class is chosen at random. What is the probability that the student has a sister?

Number of events = Number of students that have a sister = S

Number of possible outcomes = £ represents 29 students in class

The probability that the student has a sister = S/£

b)One of the students who has a brother is chosen at random. What is the probability that this student has a sister?​

This is calculated as

The Probability of Students that have a brother and a sister = Probability of students that have a brother × Probability of student that have a sister.

Number of students that have a brother = B

Number of students that have a sister = S

The Probability of Students that have a brother and a sister = B/£ × S/£

= BS/£²

D. She is correct; the histogram is skewed to the right because there is less data on the right side.

Step-by-step explanation:

I just did it on edge

Option D is correct. She is correct; the histogram is skewed to the right because there is fewer data on the right side.

A skewed distribution is one in which one of the two sides is biased (either left or right). It's like a mountain tilting to one side (left or right).

Like the picture, a left skewed graph has an extended tail on the left side of the main peak. A right skewed graph features an extended tail on the right side of the main peak.

She is correct; the histogram is skewed to the right because there is fewer data on the right side.

Hence, option D is correct.
