Answer: $17,000 invested in bonds and $13,000 in certificate of deposit
Step-by-step explanation: let x = amount invested in bonds
y = amount invested in certificate of deposits.
According to the question, amount invested in bonds is $4000 more than the amount invested in certificate of deposits.
x = y + $4000 — (1)
Also from the question, the total money for investment is $30,000
x + y = $30,000 — (2)
By substituting eqn (1) into eqn (2), we have
y + 4000 + y = 30, 000
2y + 4000 = 30,000
2y = 30,000 - 4000
2y = 26,000
y = $ 13,000
But x + y = 30,000 where y = 13,000
x + 13, 000 = 30,000
x = 30,000 - 13,000
x = $17,000
Hence $17, 000 is invested in Bonds and $13, 000 in certificate of deposit

Answer:
18/36 in simplest form is 1/2.
1 5/8 to an improper fraction is 13/8
19/5 to mixed fraction is 3 4/5 in simplest form
Step-by-step explanation:
18 and 36 in share a common denominator of 18. 18 divided on 18 is 1. 36 divided on 18 is 2. so 1/2 is equivalent to 18/36.
1 5/8 equals one whole (8) plus 5. 8 + 5= 13. 13/5 is your answer
19 divided on 5 is 3.8. 3.8 converted to a fraction is 3 and 0.75. 0.75 in fraction form is 4/5. your answer is 19/5 = 3 4/5 or 3 and 8/10.
If this was correct then mark as brainliest.

Answer: 0.045</h3>
Explanation:
The sample proportion 0.617 is at the exact midpoint of the interval from 0.572 to 0.662
We can confirm this by applying the midpoint formula.
The distance from the center (0.617) to either endpoint will be the margin of error. In other words, it is half the width of the confidence interval
L = lower boundary of confidence interval = 0.572
C = center of confidence interval = 0.617
U = upper boundary of confidence interval = 0.662
We have three methods to find the confidence interval
- margin of error = U - C = 0.662-0.617 = 0.045
- margin of error = C - L = 0.617 - 0.572 = 0.045
- margin of error = (width)/2 = (U-L)/2 = (0.662-0.572)/2 = 0.045
Each yielding the same result of 0.045
With the third method, you don't need to know the center of the confidence interval.
