Answer:
a score of 105 is one standard deviation above the mean
the rule says that 68% of a normally distributed population lies within one standard deviation of the mean...half above the mean and half below
so 34% are within one standard deviation above the mean
this means that 16% are above that value
Step-by-step explanation:
Answer:
y=
Step-by-step explanation:
Perpendicular means opposite reciprocal of the slope. This means that the slope would change from 2/5 to 5/2 and add a negative, so it is -5/2.
y=-5/2x+b
2=-5/2 (2) +b
7=b
y=-5/2x+7
Answer:
$0.84
Step-by-step explanation:
0.28 x 3 = 0.84
0.28 0.28 0.28
= 0.84
33% 33% 33%
For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
For each of the questions we must make use of this equation in the following way:
Part A:
y = 6.81 * (1.0161) ^ t
Part B:
y = 6.81 * (1.0161) ^ 6
y = 7.49 million
Part C:
10 = 6.81 * (1.0161) ^ t
log1.0161 ((1.0161) ^ t) = log1.0161 ((10 / 6.81))
t = log1.0161 ((10 / 6.81))
t = 24.05 years
Part D:
2 * 6.81 = 6.81 * (1.0161) ^ t
log1.0161 ((1.0161) ^ t) = log1.0161 ((2 * 6.81 / 6.81))
t = log1.0161 (2)
t = 43.40 years
