Answer:

Step-by-step explanation:

3y = -x + 6

y = -1/3x + 2

y - 3 = -1/3(x + 1)

y - 3 = -1/3x - 1/3

y - 9/3 = -1/3x - 1/3

y = -1/3x + 8/3

Allushta [10]

Answer: 1st train = 364 mph, 2nd train = 356.2

Step-by-step explanation:

Train 1: x + 7.8

Train 2: x

Train 1 + Train 2 = Sum

x + 7.8 + x = 720.2

7.8 + 2x = 720.2

2x = 712.4

x = 356.2

Train 1: x + 7.8

= 356.2 + 7.8

= 364

If the class contains 11 boys and 14 girls, what is the probability of calling on a girl?

Ronch [10]

Answer: P (girl) = 14 / 25

Concept:

Here, we need to know the idea of probability.

Probability is a measure of the likelihood of an event to occur.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Number of boys = 11

Number of girls = 14

Total number of people = 11 + 14 = 25

P (girl) = Favorable / Total (refer to the attachment)

P (girl) = 14 / 25

Hope this helps!! :)

It would cost somehow less than $1000 and you would know that because 347 students is a large number, but since it hold 44 students in each bus, it’ll take not to long to get to 347. So since each bus is $95, it would at least reach to 700+

(All is estimated)
