f(x) = 8x + 1. Start by subtracting 1 from both sides.
f(x) - 1 = 8x. Divide both sides by 8.
(f(x) - 1) / 8 = x.
the inverse of f(x) = 8x + 1 is f^-1(x) = (x-1) / 8
A) The attachment shows the equation of the best-fit line. It is approximately
.. test average = 89.7 -2.93*(hours playing games)
b) The slope indicates the expected drop in test score for each hour spent playing games
c) The y-intercept is the expected test score if no hours are spent playing games.
d) The correlation coefficient is -0.92, a significant negative correlation. One might expect that hours spent playing games indicates a lack of interest in school subjects or studying, hence a likelihood that test scores will be lower.
e) The equation predicts a test score of about 75 for someone who spends 5 hours a week playing video games.
Answer:
down below!
Step-by-step explanation:
a) width: 2,3,4,5 length:9,8,7,6
all you need if for those numbers to add up to 11 together because the perimeter itself is 22 so you always want to be able to add those two numbers and be able to double it to the perimeter if that makes sense.
b) the greatest area there will be would be width: 5 and length: 6 because 5x6 equals 30 and multiplying the others would be less than that. hence 2x9=18, 3x8=24, and 4x7=28
please let me know if this helps if not I can try to explain another way!
Answer:
8
Step-by-step explanation:
base x height / 2 = the area
4 x h / 2 = 16
h = 8
so x is 8
