Explain why the binomial distribution would be classified as a discrete analytic probability distribution.

Answers

Answer:

The binomial distribution is called a probability distribution. This is a common discrete distribution that was used in the statistics.

Step-by-step explanation:

The binomial distribution is also named as a probability distribution. It is explained as the likelihood of the value will take the value of the two independent variables under the given parameters.

The binomial distribution is commonly called the discrete distribution. it is opposite to the normal distribution. The binomial distribution counts the two states which are represented as 1 and 0. It is usually used in social science statistics.

The journalist spent a year researching the foreign government's sanctions. Finally, it was time to synthesize all of the _______________ information that he had learned

Here out of four options given namely

irate, relevant, keen and strategic we find that relevant is more appropriate

So answer is relevant

Irate meaning enraged cannot suit here.

Keen is for observation and here for reading information relevant is better

Strategic is innovative ways but here not applies.

So only answer is relevant.

Step-by-step explanation:

The zeros are the values of x on the x- axis where the graph crosses.

The graph crosses the x- axis at x = - 4 and x = - 6

Then x = - 4 and x = - 6 are the 2 zeros → D

A pencil at a stationery store costs $1, and a pen costs $1.50. Stella spent $21 at the store. She bought a total of 18 items. Which system of equations can be used to find the number of pencils (x) and pens (y) she bought? x + 18y = 21 x = 1.5y 18x + y = 21 x = 1.5y x + 1.5y = 21 x + y = 18 1.5x + y = 21 x = 18y

Answers

Let x represent represent the amount of pencils that Stella bought, and y represent that number of pens that Stella bought.

We know that Stella bought 18 items total, meaning that the number of pencils and pens must equal 18 or :

x + y = 18

Additionally, we know that she spent $21, and that each pencil costs $1, and that each pen costs $1.50. Therefore,

1x + 1.5y = 21

So, the system of equations that can be used to find the number of pencils (x) and the pens (y) she bought would be:

x + 1.5y = 21
and
x + y = 18

x+1.5y=21 because you're finding the equation you would use to find the number of pencils and pens she bought.
Each pencil is $1 so that'd be 1x. When writing an equation, you don't write 1x, you just write x because that's all you have, 1 x. It's understood.
Each pen is $1.50 so that would be 1.5y.
x pencils+1.5y pens =21 dollars spent.
