A survey of statistics students who had completed BUS 203 revealed that 70% sought additional help at the ICC Learning Lab, whil

Musya8 [376]

Answer:

a) P(NP/L) = 0.1

b) P(P/L) = 0.9

c) P(P) = 0.666

d) P(L/P) = 0.945

e) P(NL U NP) = 0.37

Step-by-step explanation:

given that;

P = passing the course, NP = Not passing the course, L = Using lab, NL = not using Lab

P(L) = 70% = 0.7, P(NL) = 30% = 0.3

P(P/L) = 90% = 0.9

P(P/NL) = 12% = 0.12

the probability of not passing the course given that the student went to the Learning Lab

P(NP/L) = 1 - P(P/L)

P(NP/L) = 1 - 0.9

P(NP/L) = 0.1

the probability of using the Learning Lab and passing the course

P(P/L) = 0.9

the probability of passing the class

P(P) = P(P/L) * P(L) + P(P/NL) * P(NL)

= (0.9 * 0.7) + (0.12 * 0.3)

P(P) = 0.666

the probability that a student utilized the Learning Lab given the condition that the student passed the class

P(L/P) = [P(P/L) * P(L)] / P(P)

P(L/P) = (0.9 * 0.7) / 0.666 = 0.63/0.666

P(L/P) = 0.945

the probability of not using the Learning Lab or not passing the class

P(NL U NP) = P(NL) + P(NP) - P(NP n NL)

= 0.3 + 0.334 - (0.88 * 0.3 )

= 0.634 - 0.264

P(NL U NP) = 0.37

The line of best fit for a scatter plot is shown: What is the equation of this line of best fit in slope-intercept form?

sukhopar [10]

First find the slope.

We know these two points are in the line: (0,8) and (6,5)

$\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{8-5}{0-6} = \frac{3}{-6} = \boxed{-\frac{1}{2}}$

The slope is -1/2. The y-intercept can be found when x = 0. And we know that the point (0,8) is on the line and x = 0, therefore the y-intercept is 8.

Plugging this into the slope-intercept form which is

y = mx + b, where m is the slope and b is the y-intercept, we get:

y = (-1/2)x + 8

2/3 is what percent of 1/4

asambeis [7]

Answer:

267%

Step-by-step explanation:

you need to divide the second number by the first. This will give you the percentage.

2/3 ÷ 1/4 = 8/3 = 2.67 = 267%
