8 0

The mole fraction of the solute is given as 0.3019

<h3>The vapor pressure of the volatile solvent</h3>

The formula for the vapor pressure of the volatile solvent is given as

P = NP°

Using Raoult's law

N is defined to be the mole fraction

Po is the vapor pressure.

From P =  NP°

N = P/P°

N = 18.5/26.5

N = 0.6981

<h3>The  mole fraction</h3>

1-  0.6981

= 0.3019

The mole fraction of the solute is given as  0.3019

(b) suppose a simple random sampling process is used to select the sample of 100 women. what is the probability that at least 30
xz_007 [3.2K]

Based on the information given, the probability

of a randomly sampled woman not being

qualified for the internship will be 0.223.

The probability of a randomly sampled woman

not being qualified for the internship will be:

= P(x<20) = P(x=17) + P(x=18) + P(x=19)

= 0.005 + 0.107 + 0.111 = 0.223

Also, the probability that at least 30 percent of

the women in the sample will not meet the age

requirement for the internships will be 0.03216

In conclusion, from the information given,

a woman who does not meet the age

requirement is more likely to be selected with

a stratified random sample than with a simple

random sample.

Which graph represents the function f (x) = startfraction 4 over x endfraction?.
Fynjy0 [20]

The graph of the function is plotted below

<h3 /><h3>Graphs and functions</h3>

Graph of functions is plotted on the xy-plane. The graph can be a curve or a line depending on the nature of the function.

<h3>Linear and polynomial graphs</h3>

Most linear equations are represented by a straight line while curves can be an exponential or polynomial function.

According to the question, we are to plot the function f(x) = \dfrac{4}{x}. The equivalent graph of the function is as shown in the attachment.
