Answer:
Robbie ,sarah and the trophy weigh 61.12 kg, 54.93 kg and 8.38 kg respectively.
Step-by-step explanation:
Let the weight of Robbie = x kgs
the weight of Sarah= y kgs
the weight of the trophy =z kgs
Then, from the given data in question a set of equations can be computed:
- the weight of robbie and trophy is 69.95 kgs , that is:
x+z=69.95 ......1
- the weight of Sarah and a trophy is 63.31 kilograms,
y+z=63.31 ------------------2
- the weight of Robbie and sarah is :
x+y=116.05 kg------------------3
Solving these equations:
x=69.5-z--------------------------4
then,putting this value in 3,
69.5-z+y=116.05
y-z=46.55----------5
adding equation 2 and 5
y+z+y-z=63.31+46.55
or, 2y=109.86
y=54.93 kgs
Also,
y-z=46.55
z=8.38 kgs
Again,
x=69.5-8.38
x=61.12 kgs
Answer:
option D
Step-by-step explanation:
in a shoe store survey there are 200 customers.
given in the table is that people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.23 × 200 + 0.31 ×200
= 108
percentage of people wearing basket ball shoe =
= 54 %
we can also find it by directly adding the given value and multiplying it by 100
= 0.23+0.31 = 0.54 ×100 = 54%
hence, the correct answer is option D
