Answer:
P
=
A
1
+
r
t
Step-by-step explanation:
Given
XXX
A
=
P
+
P
r
t
Applying the distributive principle:
XXX
A
=
P
(
1
+
r
t
)
Dividing both sides by
(
1
+
r
t
)
:
XXX
A
1
+
r
t
=
P
The answer is 36/49.
You take the second fraction and flip it (it will be 12/14) and you multiply straight across. You get 72/98. You simplify it by finding it's greatest common factor (in this case it is 2) so you divide it the numerator and the denominator by 2. You get 36/49.
2 / -18 and 4/ a (1/2 ) I THINKKK
<span>The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard deviation of 50. what is the probability that a student uses more than 580 minutes?
Given
μ=500
σ=50
X=580
P(x<X)=Z((580-500)/50)=Z(1.6)=0.9452
=>
P(x>X)=1-P(x<X)=1-0.9452=0.0548=5.48%
