Three freshmen, 3 sophomores, 3 juniors, and 3 seniors are participating on the debate team. The team's captain is randomly sele
slega [8]

Answer:

C)  \frac{3}{4}

Step-by-step explanation:

Given:

Number of freshmen = 3

Number of sophomores =3

Number of juniors =3

Number of seniors = 3

The team's captain is randomly selected from any grade level.

To find the the probability that a freshman will not be selected as captain.

Solution:

Total number of members in the team = 3+3+3+3 = 12

Probability that a freshman will be selected as captain will be:

⇒   \frac{Number\ of\ freshmen}{Total\ members}

⇒ \frac{3}{12}

Reducing to simple fraction by dividing numerator and denominator by 3.

⇒ \frac{3\div3}{12\div 3}

⇒ \frac{1}{4}

Thus, probability that a freshman will not be selected as captain will be given as:

⇒ 1-\frac{1}{4}

Taking LCD.

⇒ \frac{4}{4}-\frac{1}{4}

Subtracting the numerators.

⇒ \frac{3}{4}     (Answer)

How do you multiply -5 that has an exponent of 4 but no parenthesis with 4? Please explain
muminat
A negative sign in front of any expression, is in effect a factor of -1, so -7 for example is really the same as saying -1 * 7, because the -1 is multiplying it right in front of it, therefore

\bf -5^4\implies -1\cdot 5^4\implies -1\cdot 625\implies -625&#10;\\\\\\&#10;\textit{as opposed to }(-5)^4\implies (-1\cdot 5)^4\implies (-1)^4\cdot 5^4&#10;\\\\\\&#10;(-1\cdot -1\cdot -1\cdot -1)(5\cdot 5\cdot 5\cdot 5)\implies 1\cdot 625\implies 625

W=15 no

W= 21 no

W= 1 Yes

If im right the question is just asking which variable is less than 15. 
so the only variable that is less than 15 is 1.
