Can someone translate this for me
Answer: y = 0.5x + 35
Step-by-step explanation:
let x represent the number of minutes used by the customer in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (435 - 215)/(800 - 360)
m = 220/440 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 360, y = 215 and m = 0.5 into y = mx + c. It becomes
215 = 0.5 × 360 + c
215 = 180 + c
c = 215 - 180
c = 35
The equation becomes
y = 0.5x + 35
The pH of distilled water is usually LESS THAN 7, because when it contacts air CO2 gas begins dissolving into the water.
The categorical variable covers the category or the value of the label and puts a <em>person </em>into <em>one group</em>, whereas quantitative variables have a value and some measurements.
For Example: Age is a variable quantitative, as though it takes a figure value.
- Wood type (yellow, pine, cedar) — categorical
- Type (solvent, water-based) water repellent — categorical
- Paint (millimeter) — Quantitative paint thickness
- Color of paint (white, grey, blue light) — categorical
- Quantitative weathered time (months)

Answer:
{ - 33, - 23, 2, 12 }
Step-by-step explanation:
Given
f(x) = 5x - 13 with domain { - 4, - 2, 3, 5 }
To obtain the range substitute the values of x from the domain into f(x)
f(- 4) = 5(- 4) - 13 = - 20 - 13 = - 33
f(- 2) = 5(- 2) - 13 = - 10 - 13 = - 23
f(3) = 5(3) - 13 = 15 - 13 = 2
f(5) = 5(5) - 13 = 25 - 13 = 12
Range is { - 33, - 23, 2, 12 }
