Answer:

[tex]y=\frac{1}{9}x+19/9[/tex]

Step-by-step explanation:

First get y by itself.

[tex]x-9y=-19\\-9y=-x-19\\[/tex]

Then variable y itself

[tex]y=(-x-19)*-1/9\\y=\frac{1}{9}x+19/9[/tex]

Answer:

D

Step-by-step explanation:

The set of data for which the mean is most likely greater than the median is the data given by first histogram.

A skewed distribution is a distribution having bias on one of the two sides (either left or right).

It is like leaning mountain on one side (left or right).

A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph.

This graph usually has mean < median < mode

A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph. This graph usually has:

Mode < median < mean.

For this case, we can try to find the histogram which is right skewed because for right skewed graphs, the mean of the data is greater than the median.

For being right skewed, the histogram needs to be elongated on the right. The elongation on right means the perpendicular axis of the graph (the frequency) has lower and lower values in the right end of the graph.

So, the histogram, which has all values having approx lower frequencies on the right side than any other part of the histogram, has got its mean > median.

We're given these histograms:

    Age                Frequency

0 - 1 years                   1

2 - 3 years                   4

4 - 5 years                   2

6 - 7 years                   0

8 - 9 years                   1

    Age                Frequency

0 - 1 years                   0

2 - 3 years                   3

4 - 5 years                   4

6 - 7 years                   3

8 - 9 years                   0

    Age                Frequency

0 - 1 years                   0

2 - 3 years                   1

4 - 5 years                   2

6 - 7 years                   4

8 - 9 years                   1

    Age                Frequency

0 - 1 years                   2

2 - 3 years                   1

4 - 5 years                   4

6 - 7 years                   1

8 - 9 years                   2

The second and fourth histograms are symmetric, because of symmetric values on its either side of the mid value for 4-5 years old dogs' frequencies. Thus, they're not skewed.

The third histogram is negatively skewed because of high values on right side (the last values in the table belongs to bigger ages, and on the axis for age of dogs, by sign convention, the bigger ages will be on right to the smaller age values) than the smaller values, and smaller values are forming tail on left side. Thus, its negatively skewed distribution.

The first histogram has positively skewed distribution, since at the end, it has very small values and there is mountain like structure on the left side.

Thus, for this histogram, the median  < mean is most likely to be happening. (we still use the word 'likely' since the data is not large enough to apply these approximations of mean and median and mode, as it works better for large data sets).

Thus, the set of data for which the mean is most likely greater than the median is the data given by first histogram.

The graph of the first histogram is attached below.

The equation of the line of best fit of Hannah's dataset represented by the graph is y = 1.25x  - 1

From the given figure, we have the following points on the line of best fit:

(x,y) = (2,1.5) and (4,4)

Start by calculating the slope (m) using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{4 -1.5}{4 - 2}[/tex]

Evaluate the differences

[tex]m = \frac{2.5}{2}[/tex]

Divide

m = 1.25

The equation is then calculated using:

y = m(x - x₁) + y₁

So, we have:

y = 1.25(x - 2) + 1.5

Open the bracket

y = 1.25x - 2.5 + 1.5

Evaluate

y = 1.25x  - 1

Hence, the equation of the line of best fit is y = 1.25x  - 1

The value of x will be the number of days between May 26 and May 12. That value is ...

  x = 26 -12 = 14

Then the number of mosquitos is estimated to be ...

  y = 230,000(1.06^14) ≈  520,008

About 520,000 mosquitos will inhabit the city on May 26.

Additional comment

Typically, an "estimate" is one or two significant figures. So, 520,000 is a reasonable estimate. 520,008 has more precsision than can be justified.

Answer:

The side lengths will form a triangle because 6+4 > 7

Step-by-step explanation:

For side lengths, the two smallest sides (ex. 6 and 4) must have a greater sum than then highest side length. Since 6+4 is greater than 7, it creates a triange. If it would have been 5+2 it would not have worked because it needs to be greater than, not less than or equal to.

Answer:

15 cm (to the nearest cm)

Step-by-step explanation:

Circumference of a circle = πd   (where d is the diameter)

Large disc

⇒ circumference = 3.14 × 27.3 = 85.722 cm

Small disc

⇒ circumference = 3.14 × 22.5 = 70.65 cm

Difference between circumferences

= circumference of large disc - circumference of small disc

= 85.722 - 70.65

= 15.072

= 15 cm (to the nearest centimeter)

Answer:

The value of x = -1/2

Step-by-step explanation:

=> 10(2x-4)=100x

=> 20x - 40 = 100x

=> -40 = 100x - 20x

=> -40 = 80x

=> -40/80 = x

=> -1/2 = x

18π

Step-by-step explanation:

so first you need to find the area of both semi- circles. To do this you will use the formula 1/2πr^2 since it is half the area of a circle.

So for the smaller semi circle you do 1/2×π×8^2 to get 32πcm^2.

Now for the large semicircle you do 1/2×π×10^2 to get 50πcm^3.

Now you take 50π from 32π to get just the area of the shaded region.

This is 18π or 56.55cm^2

Using proportions, considering the ratios, it is found that Danil receives 65.33 euros.

A proportion is a fraction of a total amount.

Danil, gabriel and hadley share some money in the ratios 3:5:9. Hence, the fraction of the total amount that Danil and Hadley receive are given by:

[tex]D = \frac{3}{17}n[/tex]

[tex]H = \frac{9}{17}n[/tex]

The amount of money that hadley receives is 196 euros, hence the total amount is found as follows.

[tex]196 = \frac{9}{17}n[/tex]

[tex]n = \frac{196 \times 17}{9}[/tex]

n = 370.22.

Hence, the amount received by Danil is given by:

[tex]D = \frac{3}{17}n = \frac{3}{17} \times 370.22 = 65.33[/tex]

Step-by-step explanation:

Because that's the dilation equation or formula

The equations will be re-written such that the expression on one side can be graphed and the x-intercepts of the graph would indicate the solution.

A) 3X² = 81

Rewritten, we have  3X² - 81 = 0

This is also = 3(X² - 27) = 0

B) (X - 1)(X + 1) - 9 = 5X

Open the brackets and we have X² - 1 - 9 - 5x = 0

Simplified, we have X² - 5X - 10 = 0

C) X² - 9x + 10 = 32

Collect like terms and we have:
X² - 9X - 22 = 0

D) 6x(x - 8) = 29

Expand the bracket and collect like terms such that the equation is equal to zero and we have

6X² - 48x - 29 = 0
