Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their
ages is 92. Which equations could be used to find Hannah's age, h, if she is the older sibling?

Answer:

20 feet up

Step-by-step explanation:

its quite simple really, just add 15+5 and you get 20

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

Step-by-step explanation:

Answer:

irrational because the square root of 51 is irrational.

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.

Answer:

29

Step-by-step explanation:

What we do here is that we plug in 2 here like a puzzle.

f(2-5) = f(-3)

So, when we plug in 2 to the function, we get a f(-3)

Nowe take f(-3)

= 3(-3)²-4(-3)-10

= 3(9)+12-10

= 27+12-10

= 29

Answer:

Step-by-step explanation:

divide the figure into 2 rectangle the one on top and bottom. Th one on top's dimensions would be length = 9 width = 3.

the bottom rectangles dimensions would be length = 5 (because 9-4) and width would be 3 (because 6-3)

so top rectangle : 9*3 = 27

bottom rectangle: 5*3 = 15

27+15 = 42

Answer:

[tex]A_{total} = 42\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the left rectangle

[tex]A = l * w[/tex]

[tex]A = 6\ cm * (9\ cm - 4\ cm)[/tex]

[tex]A = 6\ cm * 5\ cm[/tex]

[tex]A = 30\ cm^2[/tex]

Step 2:  Determine the area of the right rectangle

[tex]A = l * w[/tex]

[tex]A = 4\ cm * 3\ cm[/tex]

[tex]A = 12\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 30\ cm^2 + 12\ cm^2[/tex]

[tex]A_{total} = 42\ cm^2[/tex]

Answer: [tex]A_{total} = 42\ cm^2[/tex]

Step-by-step explanation:

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:

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

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:

y=36,x=108,z=30

Step-by-step explanation:

1)180°=72°+(3y)°

=>(3y)°=180°-72°

=>(3y)°=108°

=>3y=108

=>y=36

2)(x)°=(3y)°=>x=108

3)(3z+18)°=108°=>3z+18=108=>3z=90=>z=30

Answer:

x = 108

y = 36

z = 30

Step-by-step explanation:

(x)° + 72° = 180° (interior angles on the same side of transversal)

-> (x)° = 180 - 72°

-> (x)° = 108°

-> x = 108

(3y)° = (x)° (corresponding angles)

-> 3y = x

-> 3y = 108

-> y = 108/3

-> y = 36

(3z + 18)° = (x)° (corresponding angles)

-> 3z + 18 = x

-> 3z + 18 = 108 - 18

-> 3z = 108 - 18

-> 3z = 90

-> z = 90/3

-> z = 30
