Answer:
a. y = 7500 - 500x
b. $ 4,500
Step-by-step explanation:
a. Given,
The original value of the phone = $ 75,00
Let the linear function that shows the value of booth after x years,
y = b - ax,
For x = 0 years, y = 7500
⇒ 7500 = b - a(0) ⇒ b = 7500
For x = 15, y = 0,
0 = b - 15x ⇒ 0 = 7500 - 15a ⇒ 15a = 7500 ⇒ a = 500
Hence, the function that shows the value of car after x years,
y = 7500 - 500x
b. if x = 6,
The value of the booth after 6 years would be,
y = 7500 - 500(6) = 7500 - 3000 = $ 4,500
Answer:
250 cubic centimeters of water
Step-by-step explanation:
In this question, we are asked to calculate the volume of water in cubic centimeters given to each of the plants.
The total volume of water is 3 * 1 = 3 liters of water
Now 12 plants was watered, this means the amount of water used on each plant would be 3/12 = 0.25 liters
Answer is wanted in cubic centimeters. This means that we will have to convert.
Mathematically;
1L = 1000 cubic centimeters
0.25 L is thus 0.25 * 1,000 = 250 cubic centimeters

Answer:
6.20%
Step-by-step explanation:
Missing question and graph attached.
Given: Total number of sample collected for female between age 20-29 is 548.
34 females that weighed over 250 pounds.
Now, finding percentage of females aged 20 to 29 weighed over 250 pounds.
Percent of Female over 250 pound aged 20-29=
⇒Percent of Female over 250 pound aged 20-29=
⇒ Percent of Female over 250 pound aged 20-29=
∴ Percent of Female over 250 pound aged 20-29=
Hence, 6.20% of females aged 20 to 29 weighed over 250 pounds.
