Consider a political discussion group of 8 democrats, 8 republicans and 6 independent suppose the teo groups meme bet are random

BartSMP [9]

Answer:

The probability of selecting two democrats is 1/380

Step-by-step explanation:

Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
Probability of an event = Number of favourable outcomes / Total number of outcomes.

Here we are given the people as,

8 democrats, 8 republicans and 6 independent.

So total number of people are: 8+6+6=20

Probability of choosing first democrat = 1/20

Probability of choosing first democrat = 1/19

Thus P( two democrats in succession ) = 1/20 ×1/19

= 1/380

Simplify 1/4-7i to get a complex number in standard a + bi form.

Romashka [77]

Answer:

$\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i$

Step-by-step explanation:

we are given

$\frac{1}{4-7i}$

Firstly, we will get rid of imaginary term from denominator

so, we will multiply conjugate to both top and bottom term

$\frac{1}{4-7i}=\frac{1\times (4+7i)}{(4-7i)\times (4+7i)}$

$\frac{1}{4-7i}=\frac{4+7i}{4^2-(7i)^2}$

$\frac{1}{4-7i}=\frac{4+7i}{16+49}$

$\frac{1}{4-7i}=\frac{4+7i}{65}$

we can also write as

so, we get

$\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i$

Find the solution(s) to the system of equations represented in the graph. They intersect at 0, negative 4 and 4, 0 (0, 4) and (4

AnnZ [28]

Answer

(0,-4) and (4,0).

Step-by-step explanation:

The solutions of a system of equation from a graph is where the graphs intersect.

From the question, you mentioned that the graphs intersect at (0,-4) and (4,0).

Therefore the solutions to the system are (0,-4) and (4,0).

Probably, you might have a straight line and a quadratic graph interesting or two quadratic graphs.
