Answer:

8. A = {Delaware, New Jersey, Pennsylvania}

9. |B| = 3

Step-by-step explanation:

8. Dates prior to 1 Jan 1788 are those in 1787. The three states admitted in 1787 are listed as Delaware, Pennsylvania, New Jersey. It is usually convenient to list elements of a set in lexicographical order:

A = {Delaware, New Jersey, Pennsylvania}

9. The months June and July appear 3 separate times on the list, so there would be 3 elements in the set B.

|B| = 3

In this problem we will be dealing with the probability density function (pdf) associated with a continuous random variable, X.

konstantin123 [22]

Answer:

$b)\ 0.568$

Step-by-step explanation:

Given

$f(x) = 6x(1- x);\ 0 \le x \le 1$

Required

$P(0.3 < x < 0.7)$

From the question, we have:

$P(a < x < b) = \int\limits^b_a {f(x)} \, dx$

So, we have:

$P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x(1 - x)} \, dx$

Open bracket

$P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x - 6x^2} \, dx$

Integrate

$P(0.3 < x < 0.7) = \frac{6x^2}{2} - \frac{6x^3}{3}}|\limits^{0.7}_{0.3}$

$P(0.3 < x < 0.7) = 3x^2 - 2x^3|\limits^{0.7}_{0.3}$

Substitute 0.7 and 0.3 for x

$P(0.3 < x < 0.7) = (3*0.7^2 - 2*0.7^3) - (3*0.3^2 - 2*0.3^3)$

Using a calculator, we have:

$P(0.3 < x < 0.7) = (0.784) - (0.216)$

Remove brackets

$P(0.3 < x < 0.7) = 0.784 - 0.216$

$P(0.3 < x < 0.7) = 0.568$

A package of dental floss has 175 m of floss. Dr.Pierre bought 150 packages to give to his patients. How many metres of dental f

grandymaker [24]

The total length of the dental floss in 150 packages will be 26250 meters.

Explanation

A package of dental floss has 175 m of floss.

Suppose, the number of meters of dental floss in 150 packages is $x$

So, the equation according to the ratio of "number of packages" to "dental floss" will be.....

$\frac{1}{175}=\frac{150}{x}\\ \\ x= 175*150=26250$

So, the total length of the dental floss in 150 packages will be 26250 meters.
