Answer:
There are 48 children.
Step-by-step explanation:
Given :There are 3 times as many boys as girls.
There are 24 more boys than girls,
To Find : how many children are there?
Solution:
Let the number of girls be x
Now we are given that there are 3 times as many boys as girls.
So, no. of boys = 3x
Now we are given that there are 24 more boys than girls.
So, 
So, no. of girls = 12
No. of boys = 3x = 3(12) = 36
Now the total no. of children = 12+36 = 48
Hence there are 48 children.
Answer
No missing money
Step-by-step explanation:
Original money given to the waiter = $30
Each person paid $10
The waitress comes back with the waitress comes back and said the bill is $25
They gave her $2 for the tip
if each got $1.00 back
Balance = $1.00 × 3
= $3.00
That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)
Each of them got $1.00 back
Total money spent = (cost of meal + tip) + balance of $3.00 given to them
= $27 + $3
= $30
Therefore, there is no missing $1.00
Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. From this definition,
For sample 1, Every fifth person who enters Little Casesars Arena for a Red Wings game. This is not biased because no person is more likely to be selected than another
For sample 2, Every tenth name in the phone. This is also not biased
because no person is more likely to be selected than another
