Answer: 600*78= 46,800
Step-by-step explanation:
"the original price of a skateboard was reduced by $15. the new price is $49."
B. p-15=49
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
Answer:
12.56
Step-by-step explanation:
The equation for the area of a circle is πr² (pi x r²). The first step is squaring r, the radius, which is 2. 2²=4. 4 x 3.14= 12.56
