Answer:
5.5
Step-by-step explanation:
18 = 6(2x - 8)
18/6 = 2x - 8
3 = 2x - 8
2x = 11
x = 11/2 or 5½
Answer:
We are given a information that:
A school for learning foreign languages has 72 students who learn German, and 54 of those students also learn Russian. There are 12 students who do not learn German but learn Russian, and 10 students do not learn either German or Russian.
Based on this information we can make our table as:
Learn German don't learn German Total
LR 54 12 66
DNLR 18 10 28
Total 72 22 94
<em>DNLR represent do not learn Russian and LR represent learn Russian.</em>
Now for finding the conditional relative frequency table we divide each of the quantities by the total sum of each row i.e. first row is obtained by dividing by 66, second by dividing by 28 and third by dividing by 94 to obtain the table as:
Learn German don't learn German Total
LR 0.82 0.18 1
DNLR 0.64 0.36 1
Total 0.77 0.23 1
The power of 10 is -5
Move the decimal point to the right until the first significant number and in this problem it is 2. It took 5 places to the right until going past the 2 and the number would be negative because going right past the decimal point will make any power negative.
