Amount of money invested: P=$4,100
Interest rate percentage in decimal form: r=7.25%=7.25/100→r=0.0725
Time in years: t=8
Total money in the account at time t: A=?
A=Pe^(rt)
A=$4,100e^(0.0725*8)
A=$4,100e^0.58
A=$4,100(1.786038431)
A=$7,322.757566
A=$7,322.76
Answer: The balance in the account after 8 years is $7,322.76
Answer:
option B...for every headband there are two hair ties
Answer:
Step-by-step explanation:
(a) R2 does not determine the level of correlation between two variables in statistics but rather it is used to determine the level of variance in a dependent variable that is explained by an independent variable. It is also known as coefficient of determination.
Pearson's correlation coefficient (r) will better explain a direct relationship between a country's literacy rate and life expectancy and the value obtained will better explain option a
(b) The slope of the line can predict an improvement in life expectancy but cannot guarantee this improvement. And as such, the use of the word "will" suggests a form of guarantee which is wrong in interpreting slopes.
4x-y=3
-y=-4x+3
y=4x-3
Since it is perpendicular, the slope must be a negative reciprocal.
therefore the slope is -x/4
Substituting the x and the y values (to find the b)
6=5/4+b
6-5/4=b
19/4=b
therefore the equation of the line is
y=-x/4+19/4
D is the answer. because
-3(12+7)=-57
