Answer:
There are 6,296 children at the carnival
Step-by-step explanation:
The number of each group of people can be expressed as;
Number of boys (b)+number of adults (a)=7,052
b+a=7,052....equation 1
Number of girls (g)=Number of adults (a)-756
g=a-756....equation 2
But Number of girls (g)=number of boys (b)
Replacing the value of b in equation 1 with that of g in equation 2;
(a-756)+a=7,052
a+a=7,052+756
2 a=7,808
a=7,808/2
a=3,904
Replace the value of a in equation 2 with 3,904
g=3,904-756
g=3,148
But since g=b
g=b=3,148
b=3,148
Total number of children=Total number of boys (b)+total number of girls (g)
Total number of children=b+g
where;
b=3,148
g=3,148
replacing;
Total number of children=(3,148+3,148)=6,296
There are 6,296 children at the carnival
Answer:
Calico Crayfish has the largest range ⇒ The range = 9
Step-by-step explanation:
∵ The rang is the difference between the largest value
and the smallest value
In the Calico Crayfish the largest value is 10 and the smallest value is 1
∴ The range = 10 - 1 = 9
In the Zebra Mussel the largest value is 10 and the smallest value is 2
∴ The range = 10 - 2 = 8
In the Blue-back Herring the largest value is 10 and the smallest value is 4
∴ The range = 10 - 4 = 6
In the Shield Darter the largest value is 9 and the smallest value is 2
∴ The range = 9 - 2 = 7
∴ The largest range is 9 in Calico Crayfish
