9/36 would be the fraction in the simplest form

Well, 84% is basically saying 84 out of 100 so as a fraction it would be 84/100. But, we need to simplify it. So we divide 4 on both the numerator and the denominator, then it becomes 21/25. So, 21/25 is 84 percent simplified into fraction form. Hope this helped.

Find the coordinates of P so that P partitions the segment AB in the ratio 6:2 if A(−4,12) and B(9,−4).

Jobisdone [24]

ANSWER

B. (5.75, 0)

EXPLANATION

If the point P(x,y) partitioned

$A(x_1,y_1)$

and

$B(x_2,y_2)$

in the ratio m:n, then

$x = \frac{mx_2+nx_1}{m + n}$

$y=\frac{my_2+ny_1}{m + n}$

If the coordinates are A(−4,12) and B(9,−4), then:

$x = \frac{6 \times 9+2 \times - 4}{6 + 2}$

$x = \frac{54 - 8}{8}$

$x = \frac{46}{8}$

$x = 5.75$

$y= \frac{6 \times - 4+2 \times 12}{6 + 2}$

$y = \frac{24 - 24}{8}$

$y = \frac{0}{24} = 0$

The correct choice is

$B. (5.75, 0)$

This problem involves the career plans of students in a biology class. Assume that the class consists of 40 percent freshmen, 10

sineoko [7]

Answer:

0.335 = 33.5% probability that the student plans to go to medical school

Step-by-step explanation:

What is the probability that the student plans to go to medical school?

Sum of:

40% of 40%(freshmen)

30% of 10%(sophomores)

35% of 30%(juniors)

20% of 20%(seniors)

$p = 0.4*0.4 + 0.3*0.1 + 0.35*0.3 + 0.2*0.2 = 0.335$

0.335 = 33.5% probability that the student plans to go to medical school

Find the volume of a sphere that has a surface area of 16π sq. in.

notka56 [123]

Sphere Surface Area = 4 • π • r²

radius = Sq Root (Sphere Surface Area / 4 • π)

radius = Sq Root (16 PI / 4 • π)

radius = Sq Root (4)

radius = 2


Sphere Volume = 4/3 • π • r³

Sphere Volume = 4/3 • π • 8

Sphere Volume = 4.1887902048 * 8

Sphere Volume = 33.51 cubic inches
