The coordinates of the point B are given as (2, - 4)

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Under a reflection in the y- axis

A point (x, y) → (- x, y), hence

A(- 2, - 4) → B(2, - 4)

Therefore the coordinates of the point B are given as (2, - 4)

Answer:

Step-by-step explanation:

slope is rise over run  2/5,  and it's positive b/c the line goes up hill.

when X =0  then the line is at -6

y = (2/5)X - 6

slope = 2/5

y intercept is -6

If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.

Hunger strikes and she wants to make it to Kono's for lunch; see picture.

Brooke can paddle at 7 mph and walk at 14 mph.

Distance from Brooke to shore will be

→ √(5² + x²)

Then the time will be

[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]

Then the distance from shore to Kono's will be

→ 6 - x

Then the time will be

t₂ = (6 - x) / 4

Then the total time will be

t  = t₁ + t₂

Then we have

[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]

t = 1/4[2√(5² + x²) + 6 - x]

If she paddles directly to point A will be

t = 1/4[2√(5² + 0²) + 6 - 0]

t = 1/4 (10 + 6)

t = 16 /4

t = 4 hr

If she paddles directly to Kono's, then we have x = 6. Then the time will be

t = 1/4[2√(5² + 6²) + 6 - 6]

t = 1/4[2√61]

t = 3.9 hr

Answer:

the answer to this question is 19

Answer: m=19

Step-by-step explanation:

First you cross multiply the two fractions. So you get 9*m = 57*3.

When you put 57*3 in a calculator you get 171. So the equation is 9m=171 and then to isolate the x you divide by 9. So when you put 171/9 in a calculator you get 19. So the correct answer is C. 19.

Answer:

By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232Step-by-step explanation:The Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:Mean = 190Standard deviation = 14Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?148 = 190 - 3*14So 148 is 3 standard deviations below the mean.232 = 190 + 3*14So 232 is 3 standard deviations above the meanBy the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232

Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:

[tex]C - O = \frac{3}{8}(P - O)[/tex]

Then, for the x-coordinate:

[tex]x + 10 = \frac{3}{8}(-2 + 10)[/tex]

x + 10 = 3

x = -7

For the y-coordinate:

[tex]y + 8 = \frac{3}{8}(8 + 8)[/tex]

y + 8 = 6

y = -2

The coordinates of point C are given as follows: C(-7, -2).

Answer:

The median of the data set:

6, 15, 30, 45, 47, 49

The middle numbers are 30 and 45 so

You have to do 30 + 45

= 75

Then do 75 ÷ 2

= 37.5

The mean of the data set:

47, 15, 6, 49, 45, 30 (add them all)

= 192

Then divide 192 by 6 (because there are 6 numbers)

192 ÷ 6

= 32

So the median is 37.5 and the mean is 32.

Answer:

y = 2x + 5

Step-by-step explanation:

Here we have the two points as (x1=1, y1=7) and (x2 = -3, y2 = -1)

Slope of this line = (y2-y1)/(x2-x1) = (-1 -7)/(-3 - 1)  = 8/4 = 2

Using slope intercept form of y = mx + c

we get y = 2 x + c

Substituing the coordinates (1,7) in this equation gives us

7 = 2.1 + c or c =5

hence y = 2x + 5

Check

if x = -3 then y = (-2)(-3) + 5 = -6 + 5 = -1 which satisfies the coordinates for the second point

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

From the stem leaf table, we can find different statistical measures.

From the picture attached, we can find different data

The minimum value  = 12

The maximum value = 49

Total number of observation = 30

The sum of the all data = 986

Mean of the data = 986/30 = 32.87

Median of the data = 34.5

Answer:

The price of other chair is $3841.25

Step-by-step explanation:

Step 1: Write equations.

First equation: The price of one type of chair is three times the price of the other.

Let x be the price of one type of chair and y the price of the other type of chair.

[tex]x = 3y[/tex]

Second equation: The total price for both is $15365

[tex]x + y = 15365[/tex]

Step 2: Solve the system of equations.

1) [tex]x = 3y[/tex]

2) [tex]x + y = 15365[/tex]

Substitute x in the second equation with x from first.

[tex]x + y = 15365\\(3y) + y = 15365[/tex]

Now solve for y (y is the price of the other chair).

[tex]4y = 15365\\y = \frac{15365}{4}\\y = \$3841.25[/tex]
