Answer:
0.249 is the required proportion.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 822
Number of people who preferred foreign cars over domestic, x = 205
We have to find the proportion of new car buyers who prefer foreign cars.
Formula:

Thus, 0.249 is the proportion of the new car buyers who preferred foreign over domestic cars..
Answer:3.73248×10^5
Step-by-step explanation:
To write (12*6)^3 as a single power,
We gets
12 × 6=72
Therefore 72^2
=373248
As a single power
3.73248×10^5
Example 1 – Constructing a frequency distribution table
Divide the results (x) into intervals, and then count the number of results in each interval. ...
Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
Answer:
Step-by-step explanation:
Hope this helps u !!
See the attached figure to better understand the problem
we know that
in the triangle ABD
<span>applying the Pythagorean theorem
y</span>²=3³+4²---------> y²=25------------> y=5 units
tan alfa=4/3-----------> equation 1
in the triangle BDC
tan alfa=DC/BD----------> tan alfa=(x-3)/4------------> equation 2
<span>matching equations 1 and 2
4/3=</span>(x-3)/4---------> 4*4=3*(x-3)--------> 16=3x-9---------> 3x=25----> x=25/3 units
the answer is
x=25/3 units
y=5 units
