Answer: Plug in x

Step-by-step explanation:

All the table is asking for you is to put in x for each equation. For question 2, y=x+5, all you have to do is add each x and get a y out for your answer. For example, 0+5=5, *+5=13, 3+5=8, etc for all problems.

erastova [34]

a) An observation.
b) A variable.
c) A population parameter.
d) A sample statistic.

Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:

(a) A Jordanian that was asked the question.

-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.

(b) The response of the Jordanian.

-A variable, since it is one of the two possible answers that the survey has.

-A population parameter, because it represents a specific percentage with respect to the total population.

(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.

-A sample statistic, since it is a statistical element that arises from the survey.

In New York City, 45% of all blood donors have type O blood. (Based on data from the Greater New York Blood Program). Find the p

quester [9]

Answer:

0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.

Step-by-step explanation:

For each donor, there are only two possible outcomes. Either they have type O blood, or they do not. The donors are selected randomly, which means that the probability of a donor having type A blood is independent from other donors. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In New York City, 45% of all blood donors have type O blood.

This means that $p = 0.45$ .

Find the probability that 5 randomly selected blood donors in NYC all have Group O blood.

This is $P(X = 5)$ when $n = 5$ . So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{5,5}.(0.45)^{5}.(0.55)^{0} = 0.0185$

0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.

A fortnight is a charming english measure of time equal to 2.0 weeks (the word is a contraction of "fourteen nights"). that is a

Hoochie [10]

In this question, you are asked to convert 2 weeks into microsecond. To answer this question you need to know how to convert weeks into days, hours, minutes, second, then millisecond. The calculation would be:

4fortnight x 2 (weeks/fortnight) x (7days/weeks) x (24 hours/day) x ( 60 minutes/hour) x (60 seconds/minute) x (1,000,000microsecond/second)= 4838400000000 or 4.384 $10^{12}$ microsecond
