The total number of both men and women surveyed was 305+279+152+459= 1195. Of this total, 279 women cooked dinner so 279/1195=0.23. This would compare with men which would be 305/1195=0.26 or slightly higher probability.

100 random samples were taken from a large population. A particular numerical characteristic of sampled items was measured. The
Marta_Voda [28]

Answer:

The median is Median  =  0.903

Step-by-step explanation:

From the question we are told that  

   The sample size is n =  100

   The  1^{st} \to 45^{th} measurements is  =  0.859 \to   0.900

    Generally since that after 0.900 we have  0.901 , then the

     46^{th} \  measurement \  is  \  0.901

in the same manner the  47^{th} \  measurement \  is  \  0.902,

Given that 0.902  was observed three times it means that

                                         47^{th},48^{th},49^{th}  \  measurement \  is  \  0.902,

Given that 0.903  was observed two times it means that

                                          50^{th},51^{th} \  measurement \  is  \  0.903,

Given that 0.903  was observed four times it means that

                                         52^{nd},53^{rd},54^{th},55^{th} \  measurement \  is  \  0.904,

Given that the highest measurement is  0.958 then then the  56^{th} \to  100^{th} \  measurement \  is  \  between \  0.905 \to 0.958

Generally the median is is mathematically represented as

            Median  =  \frac{ [\frac{n^{th}}{2}]  + [(\frac{n}{2})^{th} + 1 ]}{2}

=>        Median  =  \frac{ [\frac{100^{th}}{2}]  + [(\frac{100}{2})^{th} + 1 ]}{2}

=>        Median  =  \frac{ [50^{th}]  + [51^{th} ]}{2}

=>        Median  =  \frac{ 0.903 + 0.903}{2}

=>        Median  =  0.903

A customer/member owes $10.51 and pays $50.00 in cash. The change due is $39.49. Provide the amount owed using the smallest numb
Zigmanuir [339]

The number is 14 bill or coins

Step-by-step explanation:

The method to use the smallest number of bills and coins possible is to utilize the largest denominations possible.

The balance is $39.49

$39.49

-$20.00 -------------a $20 bill is the largest bill not larger than the total ($39.49)

-------------

$19.49

-$10.00--a $10 bill is the largest bill not larger than the remaining ($19.49)

----------

$9.49

-$5.00------a $5 bill is the largest bill not larger than the remaining ($9.45)

----------

$4.49

-$1.00-------a $1 bill is the largest bill not larger than the remaining ($4.49)

---------

$3.49

-$1.00-------a $1 bill is the largest bill not larger than the remaining ($3.49)

----------

$2.49

-$1.00------a $1 bill is the largest bill not larger than the remaining ($2.49)

----------

$1.49

-$1.00------a $1 bill is the largest bill not larger than the remaining ($1.49)

-----------

$0.49

-$0.25---- a quarter is the largest coin not larger than the remaining ($0.49)

----------

$0.24

-$0.10----a dime is the largest coin not larger than the remaining ($0.24)

---------

$0.14

-$0.10--a dime is the largest coin not larger than the remaining($0.14)

---------

$0.04

- a penny, ($0.01)  is the largest coin not larger than the remaining ($0.04). Here you have 4 pennies

the cross sectional area of a cylinder is 614 cm 2 the height is 8cm what is the volume of the cylinder​
Elina [12.6K]

Answer: Volume of the cylinder​ = 4912\ cm^2

Step-by-step explanation:

Volume of cylinder = Area of base x height

Also, area of cross section = Area of base

Volume of cylinder =  area of cross section x height

Given:  Area of cross section = 614\ cm^2

height = 8 cm

Volume of cylinder = 614 x 8

= 4912 \ cm^2

Hence, the volume of the cylinder​ = 4912\ cm^2
