The appropriate option is "True". Adding programming to your skill-set is essential if you want to be a data scientist. Math and statistics provide a strong foundation for understanding the principles and concepts behind data analysis.

However, to effectively work with data at scale and solve real-world problems, data scientists need to use programming languages and tools.

Here are several reasons why programming is necessary for data scientists:

1. Data Manipulation: Data scientists often work with large and complex datasets that require cleaning, transformation, and manipulation. Programming allows data scientists to automate these tasks and perform them efficiently. Programming languages like Python and R offer extensive libraries and packages for data manipulation, such as Pandas, NumPy, and dplyr.

2. Data Visualization: Communicating insights from data is crucial, and data visualization plays a significant role in this process. Programming enables data scientists to create visualizations and interactive plots to explore and present data effectively. Tools like Matplotlib, Seaborn, ggplot, and Plotly provide powerful visualization capabilities.

3. Machine Learning and Data Modeling: Machine learning is an integral part of data science. Programming skills allow data scientists to implement and apply various machine learning algorithms and models. Libraries like scikit-learn, TensorFlow, and PyTorch provide the necessary tools and frameworks to build and deploy machine learning models.

4. Big Data Processing: With the exponential growth of data, data scientists often encounter big data challenges. Programming languages like Python and tools like Apache Spark enable data scientists to handle and process large-scale datasets efficiently. Knowledge of programming allows data scientists to leverage distributed computing frameworks and techniques to analyze and extract insights from big data.

5. Reproducibility and Collaboration: Programming facilitates reproducibility in data science workflows. By writing code, data scientists can document their analyses, share them with others, and ensure that the results can be reproduced. Programming also enables collaboration among data scientists and allows for version control and code sharing through platforms like GitHub.

The standard deviation of the total number of pages the person will read is approximately 179.3.

To find the standard deviation of the total number of pages the person will read, we need to consider that the number of pages in the romance novel and the number of pages in the detective novel are independent random variables.

The variance of the sum of two independent random variables is equal to the sum of their variances. Therefore, the variance of the total number of pages is the sum of the variances of the romance novel and the detective novel.

For the romance novel:

Mean = 364

Standard Deviation = 47

For the detective novel:

Mean = 404

Standard Deviation = 173

Variance of the total number of pages = Variance of romance novel + Variance of detective novel

Variance = (47^2) + (173^2)

Standard Deviation = √Variance = √(47^2 + 173^2) ≈ 179.3 (rounded to one decimal place)

AC = 24

Step-by-step explanation:

First you want to set up the equation to find what x equals which is AB + BC = AC

12x - 20 = x + 6 + 5x - 4

Then combine like terms and solve.

12x - 20 = x + 6 + 5x - 4

12x - 20 = 6x +2

      +20          +20

12x = 6x + 22

-6x    -6x

6x = 22

x = 11/3 or 3 2/3

Then plug in x to the AC equation.\

The weight for mom's boxes is obtained as 41.41 pounds.

What is weight?

Weight gauges how much gravity is pulling on a body.

The weight formula is provided by -

w = mg

Since weight is a force, it has the same SI unit as a force, which is the Newton (N).

Use a proportion to solve this problem.

Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -

weight of 11 art projects / 11 = total weight / 24

Solving for the total weight -

total weight = (weight of 11 art projects / 11) x 24

total weight = 2.18 x 24

total weight = 52.32 pounds

So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -

weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)

weight of 4 art projects = (24 - (7/11) x 24)

weight of 4 art projects = 10.91 pounds

So, mom would be receiving 7 art projects weighing a total of -

weight of 7 art projects = (total weight - weight of 4 art projects)

weight of 7 art projects = (52.32 - 10.91)

weight of 7 art projects = 41.41 pounds

Therefore, mom's box would weigh 41.41 pounds.

Answer:

Step-by-step explanation:

gas mileage = miles covered/gallons used

but:

miles covered = \(35\frac{1}{2}\)

                        = 35.5

gallons used     = 1\(\frac{1}{2}\)

                           = 1.5

gas mileage = 35.5/1.5

gas mileage = 23.667 miles/gallon (to 3 decimal places)

gas mileage = miles covered/gallons used

but:

miles covered = \(27\frac{1}{5}\)

                        = 27.2

gallons used     = \(\frac{4}{5}\)

                         = 0.8

gas mileage = 27.2/0.8

gas mileage = 34 miles/gallon

c)

gas mileage of blue: 23.667 miles/gallon implies the blue car will travel 23.667 miles on 1 gallon

gas mileage of silver: 34 miles/gallon implies the silver car will travel 34 miles on 1 gallon

Hence the silver car would travel a greater distance on 1 gallon than the blue car.

Answer:

The flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

Step-by-step explanation:

We can use the following formula to calculate the flow rate:

Flow rate (mL/hr) = Volume to be infused (mL) / Time of infusion (hr)

First, we need to convert the total volume of 2 liters to mL:

2 liters = 2000 mL

Next, we can plug in the values:

Flow rate = 2000 mL / 16 hours

Flow rate = 125 mL/hr

Therefore, the flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

Answer:

1,880 people will fit in 94 ft by 50 ft

Step-by-step explanation:

We can estimate this using the area

For 5 ft by 5ft ; 10 people can fit in an area of 5 * 5 = 25 ft^2

In an area of 94 ft by 50 ft, the number of people that can fit will be;

let’s start with the area

Area = 94 * 50 = 4,700 square feet

10 people will fit in 25 square feet

x people in 4,700 square feet

25 * x = 10 * 4700

25x = 47,000

x = 47000/25

x = 1,880 people

Parabolic CoordinatesParabolic coordinates are a coordinate system that can be used to define any point in 2D Euclidean space.

In this system, points are defined by two variables u and v. The parabolic coordinates of a point in 2D Euclidean space can be found using the following equations: x = (u^2 - v^2) / 2y = uvIn this coordinate system, the differential unit of length, ds2, can be found using the equation:ds2 = du2 + dv2 + dx2where du2 and dv2 are the differentials of u and v, respectively, and dx2 is the differential of x. Cylindrical CoordinatesCylindrical coordinates are a coordinate system that can be used to define any point in 3D Euclidean space. In this system, points are defined by three variables r, θ, and z.

The cylindrical coordinates of a point in 3D Euclidean space can be found using the following equations: x = r cos(θ)y = r sin(θ)z = zIn this coordinate system, the differential unit of length, ds2, can be found using the equation:ds2 = dr2 + r2 dθ2 + dz2where dr2 and dθ2 are the differentials of r and θ, respectively, and dz2 is the differential of z. The volume element dV can be found using the equation:dV = r dr dθ dz.

Question:

Hailey ran a few laps. D(n), models the duration (in seconds) of the time it took for Hailey to run her nth lap. When did the lap duration increase faster?

A. Between the 3rd and 7th lap

B. Between the 7th and 9th lap

C. The lap duration increased at the same rate over both intervals

Answer:

B. Between the 7th and 9th lap

Step-by-step explanation:

Given

See attachment for table

Required

Determine when the lap increases faster

To do this, we simply calculate the rate of change between each lap.

From the attachment, we have:

\(D(3) = 85\)

\(D(7) = 99\)

\(D(9) = 110\)

Rate of change is calculated using:

\(Rate = \frac{D(b) - D(a)}{b - a}\)

For D(3) to D(7), the rate is:

\(Rate = \frac{D(7) - D(3)}{7 - 3}\)

\(Rate = \frac{99 - 85}{7 - 3}\)

\(Rate = \frac{14}{4}\)

\(Rate = 3.5\)

For D(7) to D(9), the rate is:

\(Rate = \frac{D(9) - D(7)}{9 - 7}\)

\(Rate = \frac{110 - 99}{9 - 7}\)

\(Rate = \frac{11}{2}\)

\(Rate = 5.5\)

The rate of change between the 7th and 9th lap  is greater than the rate of change between then 3rd and 7th lap .

Hence, (b) is correct

Answer:

B) Between the 7th lap and the 9th lap

Step-by-step explanation:

From the figure we see that the function in b, only asigns values for the points in -3, -1, 1, 3 and 4 of the x axis.

Then it's domain is

To find the range of the figure in b, we have to see what values does it take in the y axis, we notice that this values are -4, 0, 1, 4 and 5. Hence

In the case of c. we notice that the lines go on (that's is why it's represented by arrows). We note that if the lines go on, eventually they will take all the values on the x axis. Then

For the range we notice that it will take all the positive values on the y axis. then

In the case of the function a, we notice that the function assigns values to every point from -4 to 4 on the x axis. Then we can conclude that the domain is

We also notice that the values that y takes are from 0 to 4, therefore
