Answer:
Paul earned $2.6 more interest than Monica.
Step-by-step explanation:
Giving the following information:
Monica:
Initial investment= $300
Interest rate= 4.2%
Paul:
Initial investment= $400
Interest rate= 3.8%
<u>To calculate the income earned, we need to use the following formula:</u>
I= P*r*t
P= principal
r= interest rate
t= time
Monica:
I= 300*0.042*1= $12.6
Paul:
I= 400*0.038*1= $15.2
Paul earned $2.6 more interest than Monica.
Answer: 8.50 dollars
The result is positive, so this is a gain (instead of a loss)
====================================
Explanation:
Focus on the "stock JKL" row only when it comes to the percentages we'll use. We need to convert them to decimal form
15% ---> 0.15
65% ---> 0.65
20% ---> 0.20
I just moved the decimal point over 2 spots, or you can divide by 100 (eg: 15% = 15/100 = 0.15)
Multiply each of these values by their corresponding loss or gain. Use negative numbers for losses
15% chance of losing $25 ---> 0.15*(-25) = -3.75
65% chance of winning $5 ---> 0.65*(5) = 3.25
20% chance of winning $45 ---> 0.20*(45) = 9
Now add up those results: -3.75+3.25+9 = 8.50
I think it's y=8x-2 idk.....
Answer:
19.8 years old
Step-by-step explanation:
If Z=(x-μ)/σ where Z=-1.32, σ=3.2, and μ=24, then:
-1.32=(x-24)/3.2
-4.224=x-24
19.776=x
19.8
Therefore, the age of a concert attendee with a z-score of -1.32 is 19.8 years old.
