Answer:

Jason = 20yrs.old

Mandy = 15yrs.old

Explanation:

Let

J = Jason's age

M = Mandy's age

J+M=35 ..... eq. 1

J−10=2(M−10) ..... eq. 2

From eq. 1

J=35−M

Substitute this in eq. 2.

(35−M)−10=2(M−10)

35−10−M=2M−20

35−10+20=2M+M

45=3M

453=3M3

15=M

J=35−M

J=35−15

J=20

An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL.

iogann1982 [59]

Answer:

An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL. The solution which has lowest cost and operational burden is as follow:

B. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to write SQL queries against the stream.

Explanation:

The option A is not correct as this solution doesn't have lowest cost and operational burden as set up a streaming data ingestion application on Amazon EC2 and connect it to a Hadoop cluster for data processing will have more cost and operational burden.
The lowest cost and operational burden solution is that we configure input stream using Amazon Kinesis Data Streams. We can use Amazon Kinesis Data Analytics to write SQL queries against the stream.
The option c and d are also more pricey in terms of cost and operational burden as compared to Amazon Kinesis Data stream and analytics.

There is a population of owls in a forest. In one year there are 20 new owls born and 10 owls die. In this same year, 5 owls ent

Simora [160]

Answer:

The owls population increased by 13 in one year

Explanation:

The given data on the owl population are as follows;

The number of new owls born = 20 (positive increase in population)

The number of owls that die = 10 (negative decrease in population)

The number of owls that enter the forest = 5 (positive increase in population)

The number of owls that left the forest = 2 (negative decrease in population)

Let 'w' represent the number of new owls born, let 'x' represent the number of owls that die, let 'y' represent the number of owls that enter the forest and let 'z' represent the number of owls that left the forest, we get;

The change in population, ΔP = w - x + y - z

By plugging in the values, we get;

ΔP = 20 - 10 + 5 - 2 = 13

The change in the population of owls in one year is an increase in 13 owls.
