Arandom sample of 1,250 couples was asked the question, "how many children presently reside in your household? "
number of children—frequency
0——250

2——560
3 ——201
5 or more ——59
what number of children occurred the least frequently? calculate this percent
a) 2, 55.2%
b)5 or more, 4.72%
c)5 or more, 11.91%
d)4.21.67%

Option B

4.72%

Step-by-step explanation:

We know that the total number of couples surveyed was 1250

Now identify the lowest frequency and divide it by the total of couples surveyed

The lowest frequency is that corresponding to 5 children or more.

The percentage is:

Only 4.72% of couples surveyed have 5 children or more

The answer is the option B

the axial of symmetry

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
