Answer:
x = 7; y = 3
Step-by-step explanation:
I used the Trial and Error Method and found that x = 7 and y = 3
=> 7 + 3 = 10
=> 10 = 10. ✔
=> 7 - 3 = 4
=> 4 = 4. ✔
Therefore, x = 7 and y = 3
Hoped this helped.
<span>I = Prt, where P is the principal, r is the annual </span>interest<span> rate in decimal form, and t is the loan period expressed in years.
</span>
First, Let us convert 3.4% into decimal form. <span>Move the decimal point two places to the left, adding in zeros as needed. 0.034</span>
Second, lets plug in our information.
250 * 0.034 * 3 = 25.50
Your simple interest is: $25.50
Primary equation: A(x)= (5y)(3X)
Secondary equation: 5y+3X=1000
y=200-(3X)/5
A(x)=3X(1000-3X)
A(x)=3000X-9X²
Now, find the derivative of A(x) to find the max... here's the work for that, or you could guess and check.
A'(x)=3000-18X
Set derivative equal to 0
0=3000-18X
166.6666666=X
Now test the intervals
(0,166.6666) (166.66666, 1000)
1st derivative is + 1st derivative is -
Plug the X value back into the secondary equation
5y+3(166.666666)=1000
5Y=500
Y=5
Answer:
X= 166.6666666666
Y=5
Please note, this is entry level calculus, and your teacher may expect you to use a different, longer route such as guess and check.
I think they are the same.
Answer:
1/4
Step-by-step explanation:
numbers > 3 are 4,5,6
number of numbers >3=3(4,5,6)
probability=3/6=1/2
probability of drawing a head=1/2
reqd. probabilty=1/2*1/2=1/4
