In a college philosophy class during the fall semester, there were 323 students,42% of whom were male and the rest of whom were female. In the springsemester, the same number of females was in the class as in the fall, but there were only 298 total students in the class. In the spring, what percent of students were female?
A. 46%B. 58%C. 63%D. 92%
Using the percentage concept, it is found that the percentage of female students in the spring was of:
C. 63%
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
During the fall semester, 58% of 323 students were female, hence:
0.58 x 323 = 187.
Then, during the spring semester, the same amount out of 298, hence:
[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

Which of the following equations best verifies the reasonableness of the solution for
log, 128 = x?
The equations best verifies the reasonableness of the solution will be log₃ 2187 = 7 and log₃ (3⁷) = 7. Then the correct options are A and E.
What is a logarithm?Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
The equation is given below.
log₃ x = 7
Take anti-log on both side, then we have
x = 3⁷
x = 2187
Then the equation is satisfied by 2187. Then we have
log₃ 2187 = 7
log₃ (3⁷) = 7
Then the correct options are A and E.

B. is the correct option to choose.
What is inequality ?An inequality is comparing of non-equal terms or expressions.
According to the given question we have to solve the given inequality and represent it in form of a number line with appropriate symbols.
Given,
-2(3x - 1) < 8.
- 6x + 2 < 8.
- 6x < 8 - 2.
- 6x < 6.
- x < 6/6.
- x < 1.
x > -1. ( Think of moving the terms to the other side to make x positive )
This will be represented in a number line with open circle staring from -1 to positive infinity.

3. Find any three rational numbers between 1/2 and 3/2
Answer:
[tex] \frac{2}{3} \\ \\ \frac{2}{2} \\ \\ \frac{4}{3} [/tex]
Step-by-step explanation:
I hope that is useful for you :)
Answer:
For example 1/1, 2/3 and 4/3
Step-by-step explanation:
There is a great way to generate rational numbers between other rational numbers using:
[tex]\textrm{If:~~~~~~} \frac{a}{b} < \frac{c}{d}\vspace{7pt}\\\textrm{Then:~} \frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}[/tex]
So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.
(1+3)/(2+2) = 1/1, so we got our first rational number.
Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2
(1+1)/(2+1) = 2/3
(1+3)/(1+2) = 4/3
We could also look for a number between 1/2 and 2/3 and find
(1+2)/(2+3) = 3/5
And so on, so forth :)
