The set of data for which the mean is most likely greater than the median is the data given by first histogram.
How to identify skewed graph?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:
Histogram 1:Age Frequency
0 - 1 years 1
2 - 3 years 4
4 - 5 years 2
6 - 7 years 0
8 - 9 years 1
Histogram 2:Age Frequency
0 - 1 years 0
2 - 3 years 3
4 - 5 years 4
6 - 7 years 3
8 - 9 years 0
Histogram 3:Age Frequency
0 - 1 years 0
2 - 3 years 1
4 - 5 years 2
6 - 7 years 4
8 - 9 years 1
Histogram 4: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.

danil, gabriel and hadley share some money in the ratios 3:5:9 the difference between the amount of money that gabriel receives and the amount of money that hadley receives is 196 euros. work out the amount of money that danil receives
Answers
Using proportions, considering the ratios, it is found that Danil receives 65.33 euros.
What is a proportion?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]

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

D. The side lengths will form a triangle because 6 + 7 > 4
Answers
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.
During a sale, a store offered a 15% discount on a TV that originally sold for

76.5 + .06 (76.5)
76.5 + 4.59 = 81.09 Chris will pay $81.09
A better way ( if you don't care to know the tax just the bottom line of what it will cost) would be to do:
0.765x x 1.06 = 76.5 x 1.06 = $81.09 too.
Why the 1 in front of the .06? The one includes the price of the coat so you don't have to add the tax on after.
Think about it like this. When you buy something you pay (even with an employee
discount) for all of it (100%) + the tax (in this case, it's 6%) So you pay 106% of the cost of the item. 106% = 1.06

Answers
Answer:
Step-by-step explanation:
a)
First I will calculate the equation of the line that goes trough the points
C (0, 0) and (-4, 3).
y= mx + b
y = [(3-0)/ (-4 -0) ] x + 0
y = (-3/4)x →the slope of tis line is (-3/4)
The slope of line l is the negative reciprocal of (-3/4) the slop of line that goes trough points C (0, 0) and (-4, 3) because the lines are ⊥.
Slope of line l is 4/3
b)
The equation of l is
y= (4/3)x + b
for point (x= -4, y = 3) that belongs to the line l, we have
3 = (4/3) (-4) + b
3 = (-16/3) + b
3 + (16/3) = b
(9+16)/3 = b
25/3 = b
The equation of the line l in slope intercept form is :
y = (4/3)x + (25/3)
c)
The radius of circle C is the distance between C (0, 0) and (-4, 3).
d² = (x2-x1)² +(y2-y2)²
d = √(-4-0)² +(3-0)²
d = √16+ 9
d = 5 → the radius of the circle C is 5
d)
Line l intersects the y-axis at (25/3) as we previously found out.
The radius is 5.
...therefore the distance between the line l's y-intercept and the circumference of the circle is
(25/3 ) - 5 = (25 - 5·3)/3 = 10/3

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

Answers
Answer:
about 520,000
Step-by-step explanation:
Following directions, we evaluate the equation by putting the value where the variable is and doing the arithmetic.
__
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.

In game 2, the small disc is used and has a diameter of 22.5. The circumference of the flying disc for the first game is how many centimeters greater than the circumference of the flying disc used for the second game, to the nearest centimeter? Use 3.14 for \piπ.
Answers
Answer:
15 cm (to the nearest cm)
Step-by-step explanation:
Circumference of a circle = πd (where d is the diameter)
Large disc
diameter (d) = 27.3 cmπ = 3.14⇒ circumference = 3.14 × 27.3 = 85.722 cm
Small disc
diameter (d) = 22.5 cmπ = 3.14⇒ 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
