Given:
The set of ordered pairs in the options:
(a) (2, 3), (2, 2), (2, 4), (2, 9), (2, –2)
(b) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4)
(c) (1, 0), (2, 0), (1, 3), (4, 3), (5, 7)
(d) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
To find:
The set of ordered pairs that could represent a function.
Solution:
A set of ordered pairs represent a function, if there exist unique output (y-value) for each input (x-value).
In option (a) we have, five output values y=3,2,4,9,-2 for single input x=2. So, it is not a function.
In option (b) we have, three output values y=5,6,4 for single input x=1. So, it is not a function.
In option (c) we have, two output values y=0,3 for single input x=1. So, it is not a function.
In option (d), all inputs has unique output.
Therefore, the correct option is (d).
Answer:
(5, 1), (7,3), (9,5), (11, 7), (13, 9)

Aimee and Stan work in the same department for a large corporation. They are curious about the proportion of their coworkers who have children. Aimee obtains a list of all the workers in the department, randomly picks 20 names from the list, and asks those coworkers if they have children. She finds that 72% of those surveyed have children. Stan waits in the break room one morning and asks the first 20 coworkers that pass by if they have children. He finds that 85% of those surveyed have children. Which result is the better estimate of the proportion of coworkers who have children?
Neither result is a good estimate.
85%
72%
Both results are equally good estimates.

Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card how many spaces forward or backward does a Player move after drawing a yellow card justify your answer
Complete question :
designs a board game in which a card is drawn on each turn. • A blue card means move forward 4 squares. • A red card means move back 6 squares. Liam suggests adding some other cards to Sia's game Part A Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card. How many spaces forward or backward does a player move after drawing a yellow card? Justify your answer.
Answer:
2 squares backward
Step-by-step explanation:
Given the rule :
Blue card = 4 squares forward
Red card = 6 squares backward
Yellow card = drawing a blue followed by a red
Spaces moved after drawing a yellow card:
Yellow equals :
Blue = + 4 squares ; then
Red = - 6 squares
Net total movement :
Blue + red
+4 + (-6)
4 - 6
- 2
2 squares backward

180 feet / day is how many centimeters (cm) /hour?
Answer:
1.27cm/hour
Step-by-step explanation:
there are 24 hours in a day, and 30.48 centimeters in a foot.
180 / 24
7.5
so that is 7.5feet / hour
convert the feet into centimeters
228.6 cm/hour
Unit conversion is a way of converting some common units into another without changing their real value. 180 feet per day in centimeter per hour will be equal to 228.6.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value.
for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given the rate as 180 feet per day. This can be written in cm/hour as,
180 feet per day
= 180 feet / 1 day
Since 1 feet equal to 30.48 centimeters, also, 1 day has 24 hours, therefore,
= (180 × 30.48) centimeters / (1 × 24) hours
= 228.6 centimeters/ hour
= 228.6 centimeters per hour
Hence, 180 feet per day in centimeter per hour will be equal to 228.6.
