Step-by-step explanation:
Answer:
3/20
Step-by-step explanation:
15 and 100 both have a common factor of <em>5</em>. To simply an expression, you have to get both the numerator (top number) and the denominator (bottom number) to be as low as possible (to make it so that both can't be divided anymore or don't have shared factors). We divide both sides by 5 (which still retains as an integer and has the same value) and so 15/3=5 and 100/5=20.
Have a nice day! :)
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.
X=number of bags of peanuts.
y=number of cups of lemonade.
We suggest this system of equations.
0.35x+0.75y=7.05
y=x+5
solve by substitution method.
0.35x+0.75(x+5)=7.05
0.35x+0.75x+3.75=7.05
1.1x=7.05-3.75
1.1x=3.3
x=3.3/1.1=3
y=x+5
y=3+5=8
Answer:
8 cups of lemonade
