Answer:
Step-by-step explanation:
Scale= length on drawing / actual length
Let the actual length b x
3:10=2/5/x
3/10=2/5x
Cross multiply
15x=20
x=4/3
The actual length is 4/3
Answer: 68
Step-by-step explanation:
First Equation:
0.6 +(0.4+0.9) =n
Step 1: do parentheses first:
0.4+0.9 = 1.3
Step 2: Add 0.6 + 1.3
0.6 + 1.3 = 1.9
n= 1.9
Second Equation:
(1.57 + 0.75) + 0.25 + n
Step 1: do parentheses first:
1.57 + 0.75 = 2.50
Step 2: Add 2.50 + 0.25 = 2.75
Step 3: Add 2.75 and n = 2.75+n
Final Answer:
1.9 +2.75+n = 4.65 +n
Hope this helps!!
Answer:
Median
Step-by-step explanation:
The median value of a distribution is obtained by :
FIRSTLY : Arranging the data in order usually ascending order.
Then the 50th percentile of the data is determined , the value which falls in the 50th percentile is the median of the distribution. The 50th percentile is the exact mid value of the distribution.
This describes the exact same way Tia was chosen in the scenario described above. Hence the measure of the center described is the Median.
