konstantin123 [22]3 years ago
7 0

Answer:

1

Step-by-step explanation:

The range is the difference between the largest and smallest values.

range = 9 - 2 = 7

If 2 is replaced by 3 then 3 becomes the smallest value and

range = 9 - 3 = 6

That is the range decreases by 1

posledela

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Have a Spanish Jury possibility= 0.40

Jury member No. to be chosen= n= 12

Hispanic Juror Expected = np = 12\times 0.40 = 4.8

The jury group will be constituted by Hispanic Jurors 4.8

OR

The binomial distribution defines the behavior of a count variable X, provided:

There are a set number of data points n.

Set n=12

Each perception is independent. This will not affect others if your first juror is selected

One of two results is that each observation ("success" or "failure"). English or not

Each result has the same chance of "success" p. for every p=0.40

Well by the binomial distribution. Mean=E(x)=np=4.8

Estimate the number of DVDs that will be checked out for every 100 patrons.
anastassius [24]

The number of DVDs that will be checked out for every 100 patrons will be 20.

<h3>How to find that a given condition can be modeled by binomial distribution?</h3>

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

 

X \sim B(n,p)

The probability that out of n trials, there'd be x successes is given by

P(X =x) = \: ^nC_xp^x(1-p)^{n-x}

The expected value of X will be:

E(X) = np\\

The information is given in the table.

The probability of getting DVDs will be

\rm p = \dfrac{2}{10}\\\\p=2

The value of n is 100.

Then the number of DVDs that will be checked out for every 100 patrons will be

\rm E(X) = 100 \times 0.2\\\\E(X) = 20

If a mole of sodium chloride weighs approximately 58 grams, and you have 29 grams of sodium chloride, how many moles of sodium c
Alexus [3.1K]
The answer is <span>A.0.5 moles 

</span><span>a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
</span><span>you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g

1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M</span>

Karl set out to Alaska in his truck.
Ivenika [448]

Considering the linear function described, 500 liters of fuel were initially in the tank.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Researching this problem on the internet and looking at the graph, we have that when x = 0, y = 500, that is, the y-intercept is of 500. From the bullet points, the y-intercept is the initial value, hence 500 liters of fuel were initially in the tank.

(5/6)^4x=(36/25)^9-x, please help solve for x, and the 9-x is all superscript
stiks02 [169]
\frac{36}{25}=\frac{6^2}{5^2}=\left(\frac{6}{5}\right)^2=\left(\frac{5}{6}\right)^{-2}\\\\therefore:\\\\\left(\frac{5}{6}\right)^{4x}=\left[\left(\frac{5}{6}\right)^{-2}\right]^{9-x}\\\\\left(\frac{5}{6}\right)^{4x}=\left(\frac{5}{6}\right)^{-2(9-x)}\iff4x=-2(9-x)\\\\4x=-2\cdot9-2\cdot(-x)\\\\4x=-18+2x\ \ \ \ \ |subtract\ 2x\ from\ both\ sides\\\\2x=-18\ \ \ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{x=-9}


Use:\\a^{-n}=\left(\frac{1}{a}\right)^n\\\\\left(a^n\right)^m=a^{n\cdot m}\\\\\left(\frac{a}{b} \right)^n=\frac{a^n}{b^n}
