Answer
m=4
Step-by-step explanation:
41/50%=82
28800-82= 28718.
That may be the answer.
Sunscreen A will likely last longer than Sunscreen B since the IQR is larger for A than B (the Boxed portion) therefore it's likely to be more reliable.
Answer:
B : y = 0.1x + 5
Step-by-step explanation:
using the y = mx + b equation
b is the intercept on the y axis ( x = 0)
m is the slope of the line.
From the graph we can see that the intercept is (0,5), therefore b = 5;
To calculate slope (m) pick two pints on the line e.g (100, 15) and (0, 5)
m = (y2 - y1)/(x2 -x1) = (15 - 5)/(100 - 0) = 10/100 = 0.1
m = 0.1
therefore in y = mx + b
y = 0.1x + 5
It is indeed 70, you divid 63 by 90 and your answer should be .07 so if you add that to your starting 63 you get 70
