Which product is positive?

Answers

Option D:

$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$ is positive product.

Solution:

Some basic rules of product:

If the negative sign is in even number of times then the product is positive.

If the negative sign is in odd number of times then the product is negative.

To find which product is positive:

Option A:

$$\left((2)/(5)\right)\left(-(8)/(9)\right)\left(-(1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative signs = 3 which is odd

So, the product is negative.

Option B:

$$\left(-(2)/(5)\right)\left((8)/(9)\right)\left(-(1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative signs = 3 which is odd

So, the product is negative.

Option C:

$$\left((2)/(5)\right)\left((8)/(9)\right)\left((1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative sign = 1 which is odd

So, the product is negative.

Option D:

$$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$

Here, number of negative sign = 2 which is even

So, the product is positive.

Hence option D is the correct answer.

$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$ is positive product.

Answer:d’s right

Step-by-step explanation:

153.8=3.14(r)squared

Answers

153.8 = 3.14r^2

Divide each side by 3.14 to get r alone.

48.9 = r^2

Take the square root of each side to isolate r.

r = 6.999

r= 7

r=12.27

153.8-3.14=150.66

150.66 square root is 12.27

Give the numerical value of the parameter p in the following binomial distribution scenarioA softball pitcher has a 0.721 probability of throwing a strike for each pitch and a 0.279 probability of throwing a ball. If the softball pitcher throws 19 pitches, we want to know the probability that more than 15 of them are strikes.

Answers

Answer:

$P(X>15)= P(X=16)+P(X=17)+P(X=18)+P(X=19)$

$P(X=16)=(19C16)(0.721)^(16) (1-0.721)^(19-16)=0.112$

$P(X=17)=(19C17)(0.721)^(17) (1-0.721)^(19-17)=0.051$

$P(X=18)=(19C18)(0.721)^(18) (1-0.721)^(19-18)=0.015$

$P(X=19)=(19C19)(0.721)^(19) (1-0.721)^(19-19)=0.002$

And replacing we got:

$P(X>15)= P(X=16)+P(X=17)+P(X=18)+P(X=19) =0.112+0.051+0.015+0.002= 0.1801$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^(n-x)$

Where (nCx) means combinatory and it's given by this formula:

$nCx=(n!)/((n-x)! x!)$

Solution to the problem

For this case our random variable is given by:

$X \sim Binom(n = 19, p = 0.721)$

For this case we want this probability:

$P(X>15)= P(X=16)+P(X=17)+P(X=18)+P(X=19)$

$P(X=16)=(19C16)(0.721)^(16) (1-0.721)^(19-16)=0.112$

$P(X=17)=(19C17)(0.721)^(17) (1-0.721)^(19-17)=0.051$

$P(X=18)=(19C18)(0.721)^(18) (1-0.721)^(19-18)=0.015$

$P(X=19)=(19C19)(0.721)^(19) (1-0.721)^(19-19)=0.002$

And replacing we got:

$P(X>15)= P(X=16)+P(X=17)+P(X=18)+P(X=19) =0.112+0.051+0.015+0.002= 0.1801$

$P(X> 2)=1-P(X\leq 2)=1-[0.0211+0.0995+0.211]=0.668$

Final answer:

In this binomial distribution scenario, the parameter 'p', representing the probability of success on each trial, is the probability of the pitcher throwing a strike, which is 0.721.

Explanation:

In the binomial distribution scenario you described, the softball pitcher throwing a pitch is the independent trial with two possible outcomes: throwing a strike (success) or a ball (failure). The parameter p represents the probability of success on each independent trial. From the question, we can see that the probability, or p, of the pitcher throwing a strike (success) is 0.721. Therefore, p = 0.721.

Please note that the binomial distribution model can be used when all trials are independent, the outcome of a trial is success or failure, and the probability of success remains the same for each trial. It doesn't appear that we need the number 'n' of independent trials or the random variable 'X' representing the number of successes (strikes in this case) for your question, as we were only asked for the value of 'p'.

#SPJ12

A null hypothesis is that the mean nose lengths of men and women are the same. The alternative hypothesis is that men have a longer mean nose length than women. A statistical test is done and the p-value is 0.225. Which of the following is the most appropriate way to state the conclusion? a. The mean nose lengths of the populations of men and women are identical. b. There is not enough evidence to say that the populations of men and women have different mean nose lengths. c. Men have a greater mean nose length. d. The probability is 0.225 that men and women have the same mean nose length

Answers

Answer:

b. There is not enough evidence to say that the populations of men and women have different mean nose lengths.

See explanation below.

Step-by-step explanation:

Develop the null and alternative hypotheses for this study?

We need to conduct a hypothesis in order to check if the means for the two groups are different (men have longer mean nose length than women), the system of hypothesis would be:

Null hypothesis: $\mu_(men) \leq \mu_(women)$

Alternative hypothesis: $\mu_(men) > \mu_(women)$

Assuming that we know the population deviations for each group, for this case is better apply a z test to compare means, and the statistic is given by:

$z=\frac{\bar X_(men)-\bar X_(women)}{\sqrt{(\sigma^2_(men))/(n_(men))+(\sigma^2_(women))/(n_(women))}}$ (1)

z-test: Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other.

Let's assume that the calculated statistic is $z_(calc)$

Since is a right tailed test test the p value would be:

$p_v =P(Z>z_(calc))=0.225$

And we know that the p value is 0.225. If we select a significance level for example 0.05 or 0.1 we see that $p_v >\alpha$

And on this case we have enough evidence to FAIl to reject the null hypothesis that the means are equal. So then the best conclusion would be:

b. There is not enough evidence to say that the populations of men and women have different mean nose lengths.
