<h3>Sum of Roots =<u> (-8)</u><u> </u><u> </u></h3><h3>Product of Roots = <u> </u><u> </u><u>(-84)</u><u> </u><u> </u></h3>

Step-by-step explanation:

{x}^{2}  + 6x - 14 = 0

Roots :- 6 and -14

Sum of the roots :

[6 + (-14)]

= (-8)//

Product of the roots :

a rectangle swimming pool is 4 ft deep. one side of the pool is 2.5 times longer than the other. the amount of water needed to f
mojhsa [17]

Find the are of the pool by dividing the volume by the depth:

1960 / 4 = 490

The pool is 490 square feet.


Area is found by multiplying the length by the width.

Let the width = X

We are told the length is 2.5X ( 2.5 times longer)


So we now have 2.5x * x = 490


2.5x * x = 2.5x^2


Now we have 2.5x^2 = 490


Divide both sides by 2.5:

x^2 = 490/2.5

x^2 = 196

find X by taking the square root of 196:

x = √196

x = 14


The width is 14 feet

The length is 2.5 * 14 = 35 feet

An investment advisor believes that there is a 60% chance of making money by investing in a specific stock. If the stock makes m
inessss [21]

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

Is 7x-y=6 Independent
Stella [2.4K]
1. Slope = 7

2. x-intercept = 6/7 = 0.85714

3. y-intercept = 6/ - 1 = -6.00000

Rearrange:

Rearrange the equation by subtracting what is to the right if the equal sign from both sides of the equation:

7x-y- (6) = 0
