Answer:
$4000
Step-by-step explanation:
Let B represent amount invested in account 'b'.
We have been given that an amount of $12,000 that Boris invested in fund a returned a 6% profit.
So the profit earned from fund 'a' would be
.
We are also told that the amount that he invested in fund b returned at 2% profit. So the profit earned from fund 'b' would be
.
Further, both funds together returned a 5%. We can represent this information as:

Now, we will equate profit earned from account 'a' and 'b' with profit earned from both accounts as:









Therefore, Jason invested $4000 in fund 'b'.
Answer:
The probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514
Step-by-step explanation:
Mean of Sat =
Standard deviation = 
We will use z score over here
What is the probability that a randomly selected high school senior's score on mathe- matics part of SAT will be
(a) more than 675?
P(X>675)

Z=1.75
P(X>675)=1-P(X<675)=1-0.9599=0.0401
b)between 450 and 675?
P(450<X<675)
At x = 675

Z=1.75
At x = 450

Z=-0.5
P(450<X<675)=0.9599-0.3085=0.6514
Hence the probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514
Answer:
It is a mixture of the two.
Step-by-step explanation:
Standard form would be 70,000
