In 2000 - 3250
In 2001 - 3640 

3640 - 3250 = 390 

(390/3250)*100 = 12% 

2001 - 3640 
2002 - 4100 

4100 - 3640 = 460 

(460/3640) * 100 = 12.6%

Consider the expression 12 + 12/13. Using words explain what this problem means. Solve and defend you answer.

Tems11 [23]

This problem is stating that 12 should be added to the quotient of 12 and 13. Since PEMDAS is an expression ' golden rule, first you would divide 12 by 13 to get an approximate answer of 0.92. Then, you would add 12 to 0.92. The sum of 12 and 0.92 is 12.92.

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?

Liula [17]

Answer:

3.6*10^3

Step-by-step explanation:

What is the quotient of 2.592× 10^7÷7.2×10^4

2.592× 10^7÷7.2×10^4

= (2.592/7.2)×10(7-4)

= 0.36*10^3

= 3.6*10^-1*10^4

= 3.6*10^(-1+4)

= 3.6*10^3

Hence the quotient expressed in scientific notation is 3.6*10^3

The probabilities that stock A will rise in price is 0.40 and that stock B will rise in price is 0.60. Further, if stock B rises

AleksandrR [38]

Answer:

The probability that at least one of the stocks will rise in price is 0.70.

Step-by-step explanation:

The conditional probability of event X given that another event Y has already occurred is:

$P(X|Y)=\frac{P(X\cap Y)}{P(Y)}$

Denote the events as follows:

A = stock A rises in price

B = stock B rises in price

Given:

P (A) = 0.40

P (B) = 0.50

P (A|B) = 0.50

Compute the value of P (A ∩ B) as follows:

$P(A|B)=\frac{P(A\cap B)}{P(B)}\\P(A\cap B)=P(A|B)P(B)\\=0.50\times0.60\\=0.30$

The probability that at least one of the stock rises is same as the probability of either stock A or B rising.

Compute the value of P (A ∪ B) as follows:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\=0.40+0.60-0.30\\=0.70$

Thus, the probability that at least one of the stocks will rise in price is 0.70.
