Let
x-----------> the number of kids
y----------> the number of adults
we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300
the answer is
the number of kids is 1300
Answer:
Option B
Step-by-step explanation:
Given that a candy manufacturer is interested in the distribution of colors in each of its packages of candy sold. The manufacturer randomly sample packages from multiple batches at one factory.
Because he resorts to only one factory, there may be bias in the sample. Other factories may have different processes of the settings and also if a diversified sample is taken then it is likely to represent the whole population, and hence results would be more accurate
Option A is incorrect since only one factory was done
C and D are not selected because one factory result cannot be generalised to all other factors in the same country or outside.
So answer would be
B) No, because the other factories may have different processes or the settings
Answer:
Step-by-step explanation:
The formula for the area of a rectangle is length times width. or a=lw.
To find each of the answers you multiply the two numbers.
a) 5(1/3)= 5/3 or 
inches squared
b) 5(4/3)= 20/3 or 
inches squared
c) 5/2(4/3)=20/6 or 
inches squared
d) 7/6(6/7)=56/56 or 1 inch squared
The second one isn’t a factor… if you meant (x+6) then the two zeros are 7 and -6
