Write the slope intercept form of the equation 11x-2y=-6
Pepsi [2]
The slope intercept form is
y=ax+b
So
11x-2y=-6       /+2y
11x=2y-6      /+6 both sides
11x+6=2y     (changing sides)
2y=11x+6        /:2 divide by 2 both sides
y=\frac{11}{2}x+3 - its the result

Please help!! i am super confused

Answer:

The train appears to go the same distance each minute

9mins

The cost for each person appears to be the same

Step-by-step explanation:

So for the first qu you basically want to find  the distance the train travels each minute, so for

3mins : 9km

therefore

1min : 3km

basically divide 9 by 3

then the train travels 27km, how long does it take?

if 3km = 1min

then 27/3 = 9

so it takes the train 9 minutes

Then for the second qu you'll do the same thing

2ppl : $16

so one person : 16/2

so 1 person costs $8

so for 8 ppl you multiply 8 by 10

8ppl : $80

hope this helps:))))

An urn contains 12 balls, of which 4 are white.
wel

Answer:

a) \frac{1}{3}

b) \frac{4}{12}\,,\,\frac{4}{11}\,,\,\frac{4}{10}\,,...

Step-by-step explanation:

Number of balls in the urn = 12

Number of white balls in the urn = 4

So, number of balls which are not white = 12 - 4 = 8

We know that probability = No. of outcomes/Total number of outcomes

Let A_i\,,\,B_i\,,\,C_i denotes the event of getting white ball by A, B and C

a) each ball is replaced after being drawn.

Probability = Number of white balls/Total number of balls

Solution: P(A_i)=P(B_i)=P(C_i)=\frac{4}{12}=\frac{1}{3}

b)the balls that are withdrawn are not replaced.

Solution:

If A wins: P(A_1)=\frac{4}{12}=\frac{1}{3}

If A lost and B wins: P\left ( B_1|A_1^{c} \right )=\frac{4}{11}

If A and B lost and C wins: P\left ( C_1|A_1^{c}\,B_1^{c} \right )=\frac{4}{10}

and so on....

Compare the fraction 3/5 to 1/2 and then compare 2/6 to 1/2 .use symbols in your answer.
Feliz [49]
3/5 > 1/2 ~ because 3/5 is 60% of 1 and 1/2 is 50% of 1 
2/6<1/2 ~ because 2/6 is 33% of 1 and 1/2 is 50% of 1

Hope I helped!
