Answer:
A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm
Step-by-step explanation:
This is a geometric sequence.
a%5B1%5D=1.5m=150cm, r=0.74
The formula is
a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29
Just substitute a1 = 150cm and r = 0.74
a%5Bn%5D=150%280.74%29%5E%28n-1%29
That's the rule.
For the second part, substitute n = 6
cm.
7x²-14x=0
7x²=-14x
sry idk the rest hope this helped a little bit
Answer:
1st one: (x-2)(x+10)
2nd one: (x-7)(x-3)
Step-by-step explanation:
Answer:
49.2 - 12.3 = 36.9
Step-by-step explanation:
Difference in Math terms means Subtract
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
