A graph with a slope of -3/2

1 answer:

6 0

To find the slope you rise before you run and if you can't rise then you go downwards so it would be down -3 over positive 2

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

Tell us whether the lines for each pair of equations are parallel, perpendicular, or neither:

Hatshy [7]

Two lines are parallel if the gradient (i.e. the x coefficient) of them both is the same.
Two lines are perpendicular if the gradient has its sign changed and has it's fraction flipped (i.e. a gradient of 2/3 would become -3/2, and a gradient of 10 would become -1/10)

THe first one is in the correct form already, with a gradient of -4.
Now we need to rearrange the second: $-2x+8y=5 \\ 8y=2x+5 \\ y= \frac{2}{8} x+ \frac{5}{8} = \frac{1}{4}x+ \frac{5}{8}$
The second equation has a gradient of 1/4, which is indeed the negative and reversal of -4, therefore the two lines are perpendicular.

Fran brings home $225 per week working 15 hours of which she is able to save $40. Fran wants to have $1,400 saved at the end of

Helen [10]

Fran will have a base amount of $800 saved at the end of the 20 weeks assuming she continues to get at least 15 hours and her expenses don't increase (40x20 =800). At a net pay rate of $15 per hour (225/15=15), she will need to work an additional two hours per week for a total of 17 hours to earn the $600 needed to meet her goal. [15x2= 30, 30x20=600]

Two thirds Of a number Is 3 1/2 ( three And a half) more than three eighths Of The number. Find The number.

antiseptic1488 [7]

$\frac{2}{3}x - 3.5 = \frac{3}{8}x$
$\frac{2}{3}x - \frac{3}{8}x = 3.5$
$\frac{2}{3}x - \frac{3}{8}x = \frac{7}{24}x$
$\frac{7}{24}x = 3.5$

Multiply 3.5 by 24 and then divide by 7 and you get

x = 12
