Answer:
A caucluation he can use is adding, just add 7422 and 5570 and you should get your answer.
Step-by-step explanation:
54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term.
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression
Answer:
$19,100
Step-by-step explanation:
The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.
So, we can say:
E(p) = P(p)*P + P(L)*L
Where
E(p) is expected profit
P(p) is probabilty of profit (0.7)
P is the profit (35,000)
P(L) is probability of loss (0.3)
L is the loss (-18,000)
Substituting these values, we get:
E(p) = P(p)*P + P(L)*L
E(p) = (0.7)(35,000) + (0.3)(-18,000)
E(p) = 19,100
The expected profit is $19,100
Answer:
X=1
Step-by-step explanation:
It’s 2 secant lines on a circle.

Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
