To find the equation of the line that passes through 2 points, we have to find the slope and the y-intercept
The form of the equation is y = mx + b
m is the slope
b is the y-intercept
The rule of the slope is
Since the line passes through points (0, 7) and (3, 10), then
x1 = 0 and x2 = 3
y1 = 7 and y2 = 10
Substitute m in the rule of the equation
Since b is the y-intercept (value y at x = 0)
Since the line passes through the point (0, 7), then
b = 7
The equation of the line is
The answer is C

Answer: C) Multiplying 3 and 3</h3>
=================================================
Explanation:
When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.
We also multiply the denominators together. The updated denominator is 4*5 = 20.
Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20
The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.
We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.
Answer:
Individual ratings variation from average ratings for apple devices, is on average 3.762.
Step-by-step explanation:
Standard Deviation is a measure of dispersion, around the average value (mean).
Formula : <u>Σ I (x - u)^2 I </u> , where u = mean, n = no. of units
n
Standard Deviation of the ratings for Apple devices is 3.762, implies that :-
