Answer:
Intrest Income= 434.87, Account Balance= 4434.87
Step-by-step explanation:
To solve this problem, we can use the exponential growth formula.
To find the decimal for 3.5%, divide it by 100. 3.5/100=0.035
The formula is F(T)= A(1+R)^T
A= Initial Amount
R= Regrowth rate
T= Time period
Now insert everything,
F(T)= 4000(1+0.035)^3
Now solve the problem,
4000(1.035)^3 (First do the exponent, then multiple)
1.035^3= approx 1.108717875 or 1.11
4000*1.108717875=
Our account balance is 4434.87, after 3 years.
4434.87-4000 will give us the interest income after three years,
The interest income is 434.87.
Answer: 0.4286
Step-by-step explanation:
Given : Total components = 7
Number of bad component in 7 electrical components = 1
Number of good component in 7 electrical components = 7-1=6
The number of combinations of selecting any 4 components =
The number of combinations of selecting all 4 good components =
Then, the probability that all selected components function properly will be :
Hence, the probability that all selected components function properly. is 0.4286 .
The cost of swimming lesson in winters is $60.
Step-by-step explanation:
Given,
Cost of lessons in summer = $50 per month
Raise in winter = 20%
Amount of raise = 20% of summer's cost
Amount of raise =
Amount of raise =
Cost of lesson in winter = Cost in summer + Amount of raise
Cost of lesson in winter = 50+10 = $60
The cost of swimming lesson in winters is $60.

Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm
