Answer:

it should be the top answer! (x>-3 or 2< x)

Step-by-step explanation:

since none of the circles at the end of the line are filled in. the signs are not an equal to. You dont need to bother looking at the numbers outside of the line.

take the nubers inside the line as x so x would be more than -3. and would be less than 2.

alexgriva [62]

Answer:

86

Step-by-step explanation:

Given that there are 30 students in class 10R and the mean marks for the entire class was 70%. Therefore, total mark of class = 70 x 30 = 2100

Given that there are 20 boys in the class and the mean marks for the boys was 62 %. Therefore, total mark of boys = 62 x 20 = 1240

To calculate the mean mark for the girls we need to find the total number of girl and total mark of girls. total number of girl = 30 - 20 (boys) = 10 total mark of girls = total mark of class -  total mark of boys = 2100 - 1240 = 860 mean mark for girls = 860 / 10 = 86

Eurostar is a high-speed railway service connecting
Setler79 [48]

Answer:

649 trains

Step-by-step explanation:

If there are 30 seats per carriage, and there is 18 carriages per train.

You multiple 30 and 18 to get how many seats there are in a train.

30*18 is 540 seats.

To figure out how many trains would be needed to seat 350,000 passenger, you have to divide 350,000 with 540 to get how many trains would be needed.

350,000/540 is 648.1

Since the answer is 648.1 and you can't chop a train into 10 pieces, you would need 649 trains to seat 350, 000 passengers.
