Nearest hundredth = 7.95
Nearest ones = 8
Answer:
(5x²y⁴z/2x^5z³)
Step-by-step explanation:
That's a wacky looking multiplication! All you really need to do here is multiply straight across as you usually would; reducing terms and combining like terms where applicable.
(4x²y³z/9)•(45y/8x^5z³)=
(4•45•x²y⁴z/9•8x^5z³)= (<-- I reduce here)
(5•x²y⁴z/2x^5z³)=
(5x²y⁴z/2x^5z³)
You could put the "x" into the denominator as well and combine those terms, but I don't really see a good reason to do so.
Answer:
The correct answer is $3300 for simple interest and $3312.24 for compound interest.
Step-by-step explanation:
Income as working as a lifeguard = $3000
We deposit the money in a bank which offers 2% interest annually for a period of 5 years.
Case 1 : Calculating simple interest for the given situation.
Amount after 5 years = 3000 + 3000 × 2 × 5 × = $ ( 3000 + 300) = $3300.
Case 2 : Calculating compound interest for the given situation.
Amount after 5 years = 3000 × = $ 3312.24.
Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24
This is a binomial probability problem
p = 0.35 = chance of picking 1 person who uses smartphones during meeting/class
n = 7 = sample size
k = 4 = target number of people who use their smartphone
Compute nCk = 7C4 using the nCr combination formula
nCr = (n!)/(r!*(n-r)!)
7C4 = (7!)/(4!*(7-4)!)
7C4 = (7*6*5*4!)/(4!*3!)
7C4 = (7*6*5)/(3!)
7C4 = (210)/(6)
7C4 = 35
Use this coefficient to find the binomial probability
B(k) = binomial probability for input k
B(k) = (nCk)*(p^k)*(1-p)^(n-k)
B(4) = (7C4)*(0.35^4)*(1-0.35)^(7-4)
B(4) = 35*(0.35^4)*(0.65)^3
B(4) = 0.144238
So the approximate answer is 0.144238
This value is accurate to 6 decimal places
