Step-by-step explanation:
Let's assume Debbie paid $1700 in interest, while Jan paid $9000.
Debbie Saves = $1700* 0.28
Jan Saves = $9000 * 0.28
Debbie Saves $476 in taxes
Jan Saves $2520 in taxes
10^5=100,000
100,000*3.6
360,000
360,000/2400
I believe it’s 150 bolts per minute
Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9 , we have
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12
Answer and Step-by-step explanation:
a)
expected value for the difference in sample means=3.5-3.2=0.3
b)
standard deviation of the sampling distribution of the difference in sample means
=sqrt((0.5^2/40)+(0.8^2/40))
=0.1492
c)
z=(0.3-0)/0.1492
z=2.01
P(z>2.01)=0.0222
