What is the career for data analysis?1) A career as a Data Scientist would require data analysis skills.
2) The Data Scientist computes and analyzes large amounts of data from different sources and then uses the results for interpretations. The skills required by a data scientist are skills In Statistics, calculus, Probability, Programming, Excel, Visualization, Database management, and Machine Learning. He also needs a high level of accuracy when solving problems.
3) The median value is used when the data set contains values that occur repeatedly and which contains some extremely high values. The mean value would aggravate towards higher values while the Median value would give a salary value that is an average of the data set. That is why the median value is used in salaries and housing prices calculations.

Determine the measure of each indicated angle. Show all necessary steps!
a)
We know that a 4-sided polygon's angles add up to 360 degrees
so to find x:
360-(69+118+84)=89 degrees
b)
For a 4-sided polygon we also know that the outside angles add up to 360 degree.
so to find p:
360-(100+62+106)=92 degrees

If x=3b and y=2/6b+4, what is x in terms of y?
The values of x are (4+k)/2 and 10. The value of the variable x in terms of y is x = y -4
System of equationsThese are equations that contains several equations and unknowns.
Given the following system of equation
x+y=4
x-y=k
Add both equation
x + x = 4 + k
2x = 4+k
x = (4+k)/2
For the equation
x+y-z=8
x-y+z=12
Add both equations
2x = 8 + 12
2x = 20
x = 10
The value of x from the equation is 10
Given the equations
x=3b
y = 2/6b+4,
______________
b = x/3
Substitute
y = 2/6(x/3)+4
y = x + 4
x = y - 4
Hence the value of the variable x in terms of y is x = y -4

49(17 + 3)
Step-by-step explanation:
The Distributive Law says [tex]a(b+c)=ab+ac[/tex]. But it can be used in the other direction, [tex]ab+ac=a(b+c)[/tex]. That way, you look at ab and ac to find the common factor a.

Describe the shape of the distribution for the following and justify your answer:
a. The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution:
uniform
symmetric
skewed left
skewed right
Justification:
b. Number of hours of sleep for each night of the week (weekdays only) - The horizontal axis is the day of the week (Monday to Friday) and the vertical axis is the amount of sleep in hours for that night. Shape of distribution:
symmetric
skewed left
skewed right
uniform
Justification:
c. Age of first heart attack - The horizontal axis is age. The vertical axis is frequency (number of people who had their first heart attack at that age). The population is people in the US who have had at least one heart attack. Shape of distribution:
skewed left
symmetric
skewed right
uniform
Justification:
d. Scores on the Graduate Requirement Exam - This is a standardized test for people entering graduate school. The horizontal axis would be the person's total score. The vertical axis would be frequency (number of people with that score). The population would be all GRE test takers for a given year. Shape of distribution:
skewed left
symmetric
skewed right
uniform
Justification:
As the travelling distance to work increases, number of such people decreases. Therefore this distribution shape will be skewed right.
How to depict the shape?On each weekday, the number of sleeping hours generally remains the same. So the shape of the distribution will be uniform.
In general, most people will have their first heart attack at a higher age. So the shape of the distribution will be skewed left.
Scores of GRE will have a normal distribution in general. So the shape of the distribution will be symmetric.

Answer: 55[tex]m^{2}[/tex]
Step-by-step explanation:
First find the area of the trapezoid: [tex]\frac{b1 +b2}{2}[/tex](h) : (base 1 + base 2) ÷ 2 x height
base 1 is 5m and we know the other base is parallel to the base of the rectangle so base 2 is 9m.
Since the total height is 7 m and the height of the rectangle is 5 m, subtract to get the height of the trapezoid: 7m - 5m = 2m
put the three values into the equation and solve:
(5m + 9m) ÷ 2 x 2m
(14m) ÷ 2 x 2m
7m x 2m
14[tex]m^{2}[/tex]
Find area of the rectangle which is just base x height
Which is 9m x 5m = 45[tex]m^{2}[/tex]
To find the total area, add the area of the trapezoid and the area of the rectangle. 14[tex]m^{2}[/tex] + 45[tex]m^{2}[/tex] = 55[tex]m^{2}[/tex]

How to find the function which was used to make graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
If we know that the function crosses the x-axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
Let's assume the graph of Cheryl's commute was like the one below.
We can see that she started at 0 mph.
One minute later, she was up to 65 mph, so she had accelerated (increased her speed).
At 6.5 min (5.5 min later) her speed was still 65 mph therefore, she was driving at a constant speed.
Over the next 2.5 min, her speed dropped to 45 mph, therefore she was decelerating.

Bow, let's start with the original function f(x). If first we apply a vertical dilation of scale factor 5, then we have:

Then we apply a shift of 2 units to the right, so we have:

A trader bought 30 baskets of pawpaw and 100 baskets of mangoes for 2450. she sold the pawpaw at a profit of 40% and the mangoes at a profit of 30%. if her profit on the entire transaction was 855, find the cost price of a basket of pawpaw and the selling price of 100 baskets of mangoes.
The cost price of pawpaw is 40 and the cost if the basket of mangoes is 1250.
How to calculate the price?Based on the information given, the equations to solve the question will be:
30p + 100m = 2450 .... i
1.3 × 40p - 30 p + 1.3 × 100m = 855 ..... ii
30p + 100m = 2450
12p + 30m = 855
Solving simultaneously, the price of pawpaw is 40 and the price of mango is 12.5.
Therefore, the cost of 100 basket of mangoes will be:
= 12.5 × 100
