Hi there!

The table shows the travelling time to work of 50 people.
Crank

Answer:

24.8 mins

Step-by-step explanation:

Time > timemark > frequency

0 – 10 > 10/2 = 5 > 5

10 – 20 > (10+20)/2 = 15 > 15

20 – 30 > (20+30)/2 = 25 > 13

30 – 40 > (30+40)/2 = 35 > 10

40 – 50 > (40+50)/2 = 45 > 7

The mean time for the 50 people is given by:

Mean = summation (mid time x frequency) / total frequency

Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50

Mean = [25 + 225 + 325 + 350 + 315] / 50

Mean = 1240 / 50

Mean = 24.8 mins

2/5- -3/4 what would be the answer?
Ipatiy [6.2K]

For this case we must simplify the following expression:

\frac {2} {5} - (- \frac {3} {4})

By definition of the law of multiplication signs we have to:

- * - = +

So, rewriting the expression we have:

\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15

Thus, the answer in decimal form is 1.15.

Answer:

\frac {23} {20} = 1.15

A banana has 80 calories. This is 5 calories less than one seventh of the calories in a banana split. How many calories in a ban
viva [34]
The answer is 85 times 7. Since the banana was 5 less then the split, the split is 5 more which is 85 calories but then it says it is also 1/7 of the whole split. So you simply multiply 85 and 7 because 85 was only 1/7 of the total banana split
