Find the amount of the increase and divide that by the original amount:

7.70 - 7.00 = 0.70 increase

0.70 / 7.00 = 0.1

Multiply by 100 to get the percentage:

0.1 x 100 = 10 %

The increase was 10 %

Answer:

$\mathbf{ 0.6 \times 0.5 = 0.3 }$

Step-by-step explanation:

Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.

It is given that $P(M) = 0.6$

Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event $D | M^{c}$ (D given M does not occur) is a null event, i.e

$P(D|M^{c}) = 0$

It is also given that,

$P(D|M) = 0.5$

Recall that : $P(D|M) = \frac{P(D \cap M)}{P(M)}$

Here, we are required to find $P(D \cap M)$

$P(D \cap M) =P(D|M) \times P(M)= 0.5 \times 0.6 = 0.3$

12) Why doesn't SSA prove two triangles are congruent? *

Svet_ta [14]

Ans: Four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. The same is true for side angle side, angle side angle and angle angle side.
