Answer:

Step-by-step explanation:

Start with the slope intercept equation: y=mx+b

y=-2x+1

m=-2 and b=1

Now draw a graph on your paper, place a point at +1 on the Y axis.

Next, solve for y with x=1.

y=-2(1)+1

y=-2+1

y=-1

Now graph (1,-1)

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

Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.

galina1969 [7]

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed= $\frac{Distance}{time}$

Using proportion

$\frac{a}{b}=\frac{c}{d}$

$\frac{135}{3}=\frac{36}{x}$

$x=\frac{360\times 3}{135}$

$x=8$

Hence, the time taken by Casi to drive 360 miles=8 hours

Need help with ixl please give right answer fill in the blanks please

Natasha_Volkova [10]

Answer:

y=2x-8

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept value.

It says the slope is 2, so we know that y = 2x+b. To find b, plug in a point given. We are given (9,10), so plug that into the equation, where y = 10 and x = 9. 10=2(9)+b, solve for b.

b equals -8, so the answer is y=2x-8.
