The scatter plot shows the population P of a town (in thousands) t years after 2000. Which best linear equation to model the town’s population from 2000 to 2019? A) P(t) = 1.12t + 0.20
B) P(t) = 0.02 + 1.12
C) P(t) = 0.20t + 1.12
D) P(t) = 1.12t + 0.02
The scatter plot shows the population P of a town - 1

Answers

Answer 1
Answer:

Final answer:

The best linear model to represent the town's population could be either P(t) = 1.12t + 0.20 or P(t) = 1.12t + 0.02, depending on the specific data in the scatter plot. Both these options follow the general form of a linear equation.

Explanation:

The question is related to a scatter plot, linear equation, and population study. We're looking to determine the best linear equation that models the town's population from 2000 to 2019 based on the given scatter plot. The general form of a linear equation is y = mx + b, where m represents the slope (rate of change), and b is the y-intercept (starting value). Typically, in this kind of scenario:

  • 't' would be the years after 2000,
  • 'm' would represent the rate of change of the population, and
  • 'b' would be the starting population.

Without the actual scatter plot, it's impossible to choose the most accurate option. However, options A & D are most likely because they conform to the general form. Option A, P(t) = 1.12t + 0.20, and Option D, P(t) = 1.12t + 0.02, are both viable options depending on the specific data presented in the scatter plot.

Step-by-step explanation:

find the lowest common multiple

of 5,10,15 and 21=210

42*3, 21*9, 14*7, 10*7

126/210, 189/210, 98/210, 70/210

Write y = –2/3x + 7 in standard form using integers. 2x + 3y = 21
3x – 2y = 21
–2x – 3y = 21
–2x + 3y = 7

Answers

The standard form of an equation of a line is written as:

Ax + By = C 

where A, B and C are constants.

y = –2/3x + 7 
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21

Therefore the correct answer is the first option.

Samantha builds one birdhouse in 6 3/8 hours. How many hours does it take to build 4 birdhouses?

Answers

4 times 6 3/8 is 24 12/8, which simplifies to  25 1/2.

Final answer:

Samantha takes 6 3/8 hours to build one birdhouse. To find out how long it will take to build 4 birdhouses, multiply the time it takes to build one birdhouse by the number of birdhouses. Therefore, it will take Samantha 25.5 hours to build 4 birdhouses.

Explanation:

The subject of this question is Mathematics, more specifically multiplicative operations applied to time concepts in a real-world problem-solving scenario.

Solution for the Question

  1. First, identify the number of hours it takes Samantha to build one birdhouse. That is, 6 3/8 hours.
  2. Since, she's planning to build 4 birdhouses, you need to multiply the number of birdhouses (4) by the time it takes to build one birdhouse (6 3/8 hours). Hence, 4 x 6 3/8 hours = 25.5 hours.
  3. So, it will take Samantha 25.5 hours to build 4 birdhouses.
