Here are the shopping times (in minutes) of ten shoppers at a local grocery store.

d1i1m1o1n [39]

The frequency which is to filled in the table is 3,1,2,4.

Given shopping time of ten shopkeeper: 36,20,32,18,20,33,28,34,37,23.

We have to complete the frequency in the table. Frequency of something is the number of times that number is coming.

Shopping time is given as 36,20,32,18,20,33,28,34,37,23.

Intervals for which frequency is given is 18 to 22, 23 to 27, 28 to 32, 33 to 37.

Numbers in the range 18 to 22=18,20,23 therefore 3

Numbers in the range 23 to 27=23 therefore 1

Numbers in the range 28 to 32=32 , 28 therefore 2

Numbers in the range 33 to 37=36, 33, 37, 34 therefore 4.

Hence the frequency which is to filled are 3,1,2,4.

Simplify this number 300mm:9m

DIA [1.3K]

Answer:

1 : 30

Step-by-step explanation:

300mm:9m

We need to change the meters to mm

1 meter is 1000 mm

so 9 m is 9000 mm

300mm:9000mm

Divide both sides by 300

300mm/300 : 9000/300

1 : 30

Estimate the sum to the nearest whole number 29.1 +78.9 + 41.5

lesya692 [45]

I rounded each number to the nearest whole number and added those.

29 + 79 + 42 = 150

If you add the original numbers you would get 149.5, which rounds to 150.
