<h2><u>Answer:</u></h2><h3>The Line Plot is Below.</h3><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Turn each fraction into a decimal:</h3>

$1\frac{1}{2}=1.5$

$2\frac{3}{4}=2.75$

$3=3$

$2\frac{3}{4}=2.75$

$2\frac{1}{2}=2.5$

$2\frac{3}{4}=2.75$

$3\frac{3}{4}=3.75$

$3=3$

$3\frac{1}{2}=3.5$

$2\frac{1}{2}=2.5$

$3\frac{1}{2}=3.5$

(I've included the line plot below.)

Which statement is true about this argument?

wariber [46]

Answer:

The argument is true by the law of syllogism

Explanation:

Law of syllogism states that for a valid argument form which is a syllogism having a conditional statement for one or both of its premises.

Premises:

1. If p , then q

2. if q, then r

Conclusion: if p, then r.

Let p be the statement "two angles form a linear pair",

let q be the statement "they are supplementary" and

let r be the statement "the sum of their measures is 180°"

If p, then q

if q, then r

then by the Law of syllogism statement , conclusion if q then r is true,

i,e If two angles form a linear pair, then the sum of their measures is $180^{\circ}$ .

Alejandro needs to buy bird seed from the local pet store for his parrots. A

Gnesinka [82]

First take note he only has $20 and the bag he must buy is $12.55. Also the loose seeds are $1.49 per pound.

To solve subtract 12.55 from 20

20-12.55=7.45

So after buying the 10 lb bag he has $7.45 left now divide that by 1.49

7.45/1.49=5

So after buying the 10 lb bag he can also buy 5 lb of the loose seeds!

Grasshoppers are distributed at random in a large field according to a Poisson process with parameter a 5 2 per square yard. How

HACTEHA [7]

In this question, the Poisson distribution is used.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Parameter of 5.2 per square yard:

This means that $\mu = 5.2r$ , in which r is the radius.

How large should the radius R of a circular sampling region be taken so that the probability of finding at least one in the region equals 0.99?

We want:

$P(X \geq 1) = 1 - P(X = 0) = 0.99$

Thus:

$P(X = 0) = 1 - 0.99 = 0.01$

We have that:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-5.2r}*(5.2r)^{0}}{(0)!} = e^{-5.2r}$

Then

$e^{-5.2r} = 0.01$

$\ln{e^{-5.2r}} = \ln{0.01}$

$-5.2r = \ln{0.01}$

$r = -\frac{\ln{0.01}}{5.2}$

$r = 0.89$

Thus, the radius should be of at least 0.89.
