Answer:
1. 3/8
Step-by-step explanation:
Total tossed times = 3
Total Possibilities = 8
Possibilities = (Head, Head, Head), (Tails,Tail,Tails), (Head,Head,Tails), (Head,Tail,Head), (Tails,Head,Head), (Head,Tail,Tail), (Tail,Tail,Head), (Tail,Head,Tail)
Number of options with a head and two tails = 3
So, Probability = Number of correct options ÷ Number of total possibilities
= 3 ÷ 8 or 3/8
Answer:
The monthly growth rate is 2.1%
Step-by-step explanation:
To find the monthly growth rate, we have to consider what is inside the bracket
Mathematically, what we have in the bracket should be written as;
1 + r
Thus;
1 + r = 1.021
r = 1.021-1
r = 0.021
This is same as 2.1%
Step-by-step explanation:
Morning is 4 hr 15 min
afternoon is 4 hour 15 min
together is 8 hour 30 min
8.5*14 = 119 dollars
So even postive integers are by defention in form 2k where k is a natural number so
let the sum of even integers to n=S
S=2(1+2+3+4+5+6+7+8+......+k-1+k
divide bith sides of equation 1 by 2
0.5S=1+2+3+4+5+...........+k-1+k
S=2(k+(k-1)+..............................+2+1)
divide both sides of equation 2 by 2
0.5S=k+k-1+..............................+2+1)
by adding both we will get
___________________________
S=(k+1)(k)
so the sum will be equal to
S=

so let us test the equation
for the first 3 even number there sums will be
2+4+6=12
by our equation 3^2+3=12
gave us the same answer so our equation is correct
