Answer:
x=3
y=8
Step-by-step explanation:
y-x=5
2y-x=13
subtract
-y=-8
y=8
8-x=5
x=8-5=3
Answer:
$1,958.23
Step-by-step explanation:
Annual income = $67,525
Total FCIA = 15.3% of salary
Since my annual income is $67,525 the FCIA contribution = 15.3%.
But 12.4% is for Social Security.
The remaining 2.9%(15.3% - 12.4%) will be for Medicare taxes.
The total deduction for I and my employer for medicare taxes will be:
2.9% * $67,525
= $1,958.225
The total deduction for medicare would be: $1,958.23
Note: Assuming we were asked to calculate only employee's medicare, the deduction would be 50% of $1,958.23.
Answer:
A. 0.0049
B. Yes
Step-by-step explanation:
Sample proportion = 0.64
N = 1000
Population proportion = 0.60
We solve for standard deviation
= √p(1-p)/n
= √0.60(1-0.60)/1000
= √0.60x0.40/1000
= √0.00024
= 0.0155
A.
The probability of sample >=0.64
Z>=0.64-0.60/0.0155
Z >= 0.04/0.0155
So z >= 2.5806
Using excel this equal to 0.0049
0.0049 is probability of sample proportion being 0.64 at least.
B.

Step-by-step explanation:
<u>Answer:</u>
-10,1,19
<u>Step-by-step explanation:</u>
<u></u>
x+y+z = 10 (Equation 1)
2y-x= 12 (Equation 2)
x-y+2z = 7 (Equation 3)
(Equation 2): -x = -2y+12
x = 2y-12 (Equation 4)
(Equation 1) - (Equation 3): 2y-z = 3
-z = -2y+3
z = 2y-3 (Equation 5)
Substitute (4) and (5) into (1)
x+y+z = 10
(2y-12)+y+(2y-3) = 10
5y-15 = 10
5y = 5
y=1
Substitute y=1 into (2)
2y-x= 12
2(1)-x= 12
2-x= 12
-x= 12-2
-x= 10
x= -10
Substitute y=1 and x=-10 into (1)
x+y+z = 10
-10+1+z = 10
z-9 = 10
z = 10+9
z = 19
Order: x = -10, y = 1, and z = 19
