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)

Write the equation of the line that passes through the given points. (0,5) and (-2,-4)

Sati [7]

Answer:

$y=\frac{9}{2}x+5$

Step-by-step explanation:

To find the equation of the a line that passes through the two given points, we must first find the slope between the two points. We can do this by using the slope formula. The slope formula is:

$m=\frac{y_2-y_1}{x_2-x_1}$

where m is the slope and (x₁, y₁) and (x₂, y₂) are two points.

By plugging in (-2, -4) and (0, 5) for (x₁, y₁) and (x₂, y₂) respectively, we get:

$y=\frac{5-(-4)}{0-(-2)}=\frac{9}{2}$

So the slope is 9/2. Now we that we have found the slope, we can write an equation. Normally, when we are given two points, we would pick one of the points and plug it into the point-slope form and then solve for slope-intercept form. Here, notice that one of the points give, (0, 5), is the y-intercept. Knowing this, we can plug in 5 for the y-intercept into the slope-intercept form to get our equation. Remember, slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

Pugging in 9/2 for m and 5 for b we get:

$y=\frac{9}{2}x+5$

which would be our equation.

I hope this helps. Happy studying.

In the following equations, t represents time in hours and m represents mass in mf. Which of them (if any) would have a mass les

kodGreya [7K]

Answer:

a, b, d and f

Step-by-step explanation:

To find which equation will have a a mass less than 50 mg after 2 hours, we just need to use the value of x = 2 and then verify if the values of y are less than 50:

a. y = 100*(0.5)^2 = 25 -> apply

b. y = 500*(0.3)^2 = 45 -> apply

c. y = 80*(2)^2 = 320 -> doesn't apply

d. y = 10*(1.2)^2 = 14.4 -> apply

e. y = 30*(1.5)^2 = 67.5 -> doesn't apply

f. y = 80*(0.2)^2 = 3.2 -> apply

g. y = 100*(2)^2 = 400 -> doesn't apply
