I also suggest using an app called photomath. It takes you through the steps of solving the equations and gives you the answer as well.
<span>First figure out how
many people there are all together. So mrs and mr is 2 there three
children so 2+3=5 so next round 179 to 200 and multiply 200x5. To do
that you can use the mental math way witch would be to take the whole
number out of 200 and make it 2. Then take the 5 in 200x5 and multiply
2x5. Then add the 2 zeros there were. And your estamated answer would be
1,000.
2+3=5
179=200
200x5
2x5=10
1,000
To figure out your real answer you will have to take 179 and multiply it by 5 so it will look like this:
34
179
x
5
895
Soto conculde the answer would be:
Estamated: $1,000
Exact: $895
Hope this helps!</span>
Answer:
The mean = 17.54
Step-by-step explanation:
Form a table as below;
<u>Interval Frequency{f} Midpoint of frequency{x} fx </u>
1-7 19 4 76
8-10 14 9 126
11-15 15 13 195
16-20 20 18 360
21-35 10 28 280
36-50 13 43 559
Sum 91 1596
The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency
The mean= 1596 / 91
The mean = 17.54
1. w= 52
2. x= 5
3. n=1.4
4. x= -28/9 or x=-3.1
