Write the equation in standard form 3x + 1 = 2y
yulyashka [42]
The standard form of an equation is
ax + by = c

In the question, we have the following formula
3x + 1 = 2y

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)
3x - 2y + 1 = 0

Finally we subtract 1 from both sides (since we need the number on the right side)
3x - 2y = - 1

Hence, 4. is the correct answer.

For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the standard deviation.
Yakvenalex [24]

Answer:

Sd(X) =\sqrt{1.2}=1.095

Step-by-step explanation:

Previous concepts

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".

Solution to the problem

Let X the random variable of interest, on this case we now that:

X \sim Binom(n=5, p=0.4)

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=\frac{n!}{(n-x)! x!}

The mean for the binomial distribution is given by:

E(X) =np=5*0.4=2

And the variance is given by:

Var(X) = np(1-p) =5*0.4*(1-0.4)=1.2

And the deviation is just the square root of the variance so we got:

Sd(X) =\sqrt{1.2}=1.095

The length of an alligator in a zoo is 14 5/6 feet.The everglades national parks list the longest alligator ever reocord in flor
astraxan [27]

Answer:

The difference in the lengths of the two alligators = 3

Step-by-step explanation:

First, let us make the lengths improper fractions, then we will find the difference from there.

Alligator 1:

Length = 14\frac{5}{12} = \frac{173}{12}

To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]

Alligator 2:

Length = 17\frac{5}{12} = \frac{209}{12}

Now Let us find the difference between the lengths:

\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3

Therefore the difference in the lengths of the two alligators = 3
