The double bar graph shows the number of imports and exports for a company in a certain week.

On how many days was the number of exports greater than the number of imports?

Answer: From the given double bar graph, we clearly see:

Number of imports for a company on Monday = 15

Number of exports for a company on Monday = 7

Number of imports for a company on Tuesday = 18

Number of exports for a company on Tuesday = 9

Number of imports for a company on Wednesday = 14

Number of exports for a company on Wednesday = 14

Number of imports for a company on Thursday = 15

Number of exports for a company on Thursday = 6

Number of imports for a company on Friday = 9

Number of exports for a company on Friday = 19

From the above information, we clearly see that only on Friday the number of exports are greater than number of imports. Therefore, there is only 1 day when the number of exports greater than the number of imports.

Hence the option D. 1 is correct

How do you find your y-intercept from your x-y points?

PSYCHO15rus [73]

1. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...

2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Jake drove 300 miles from his house to a soccer tournament. This graph shows the distance Jake had traveled (m) and the time tha

Bad White [126]

Part A. The trip starts at 8am which corresponds to 0 hrs, point (0hr, 0mi)

2hrs later it's 10am. .point (2hr, 140mi)

The average speed is the slope between 0 and 2 hrs. Remember the slope formula m = Δy/Δx

m = (140 - 0) / (2 - 0)

m = 70 mph

Part B. Average speed from 11am - 2pm

11am is point (3hr, 140mi)

2pm is point (6hr, 300mi)

As you can see from the graph, the speed or slope changes at 1pm (5,260). You Can just use the start and end points.

m = (300-140) / (6-3)

m = 160/3

53.3 mph

* It comes out the same solution as if you average the two different slopes. 2hrs at 60mph + 1 hr at 40mph = (120 + 40)/3 = 160/3

Part C. Total average speed = total distance / total time driving

He went 70 mph for 2 hrs

stopped for an hour (slope is zero, no speed)

60 mph for 2hrs

40mph for 1 hr

300mi /5hr = 60mph

Part D. No Question....
