Answer:
Hatim=37kg, Fatin=31
Step-by-step explanation:
Hatim=x, Fatin=x-x
x+x-6=68
add 6 to both sides
x+x=74
2x=74
divide both sides by 2
x=37
put in 37 fo the values determined earlier
Hatim=37, Fatin=37-6
Hatim=37, Fatin=31
check by plugging in the values
37+31=68 (or 37+37-6=68, either one works)

Answer: The mass of the remaining element = 1.1 grams .
Step-by-step explanation:
Exponential equation of decay: [tex]y=A(1-r)^x[/tex] ...(i), where A = intial value , r= rate of decay in decimal , x= time.
As per given :
Initial mass : A= 140 grams
Rate of decay : r= 21.6% per minute= 0.216 per minute.
x= 20 minutes
Substitute values in (i) , we get
[tex]y=140(1-0.216)^20\\\\=140(0.784)^2^0=1.077579422[/tex]
Hence, the mass of the remaining element = 1.1 grams .
Jean wants to invest a gift of $4,250 in the stock market. A broker suggests two companies, Solar Solutions (SOLR) and Frontline Medical (FLMD). He provides the probabilities for an annual return on $4,250 based on their historical gains: SOLR: 50% chance of $1,000 gain, 35% chance of $200 gain, 15% chance of $600 loss FLMD: 80% chance of $750 gain, 20% chance of $100 loss Which is the best analysis of these investments?
Answer:
the answer is the question with $580 in it please correct me if im wrong
Step-by-step explanation:
Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.
How to calculate the expected return?The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:
50% chance of $1,000 gain: 0.5 x $1,000 = $500
35% chance of $200 gain: 0.35 x $200 = $70
15% chance of $600 loss: 0.15 x -$600 = -$90
Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.
The expected return on FLMD is calculated in the same way:
80% chance of $750 gain: 0.8 x $750 = $600
20% chance of $100 loss: 0.2 x -$100 = -$20
Therefore, the expected return on FLMD is $600 - $20 = $580.
Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.
The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

Answer:
angle 2 = 128 because of a rule that I unfortunately cannot remember the name of....
angle 6 = 180 - 47 = 133
because a straight line = 180 degrees
angle 3 = 180 - 128 = 52
Same reason as angle 6
angle 1 = 52 + 47 = 99
180 - 99 = 81
Sum of the angles in a triangle = 180

Jamie deposits $627 into a savings account. The account has an interest rate of 3.5%, compounded quarterly. Write the function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit.
The function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit is A = 627(1.00875)^{4t} (in dollars)
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
For this case, we're given that:
Initial amount Jamie deposits = P = $627Rate of interest = 3.5% compounding quarterlyTime = t yearsRate of interest is compounding quarterly.
Each year has 4 quarters.
Rate of interest is usually annual rate of interest. Since compounding is done quarterly, let we express everything in quarter years.
Quarterly interest rate compounding quarterly = 3.5/4 = 0.875% = R%
t years has 4t quarters = T
Thus, we get the final amount in Jamie's account as
[tex]A = P\left(1 +\dfrac{R}{100}\right)^T\\\\A = 627 \left(1 +\dfrac{0.875}{100}\right)^{4t}\\\\A = 627(1.00875)^{4t} \: \rm \text{(in dollars)}[/tex]
Thus, the function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit is [tex]A = 627(1.00875)^{4t}[/tex] (in dollars)
