X = 4/15 or 0.26
First add the numbers on the left side of the equation.
0.72 = 0.8 - 0.3x
Then move the variable to the left as well.
0.3x + 0.72 = 0.8
Move the constant to the right by subtracting.
0.3x = 0.8 - 0.72
Subtract the numbers
0.3x = 0.08
Divide both sides by 0.3.
And that should yield your answer.
Hope this helps. ^^
Answer:
152 sq. ft
Step-by-step explanation:
to determine the square you multiply the length by the width (16 by 8)
to determine to area of the triangle you must subtract 12 by 16 in order to get the length of the triangle. then multiply the length (4) of the triangle by the height of the triangle (6)
finally add the areas of the triangle and square together to get the total length of the whole thing.
Using it's concept, the relative frequencies are given as follows:
- Republican residents of County 1: 37.9%.
- Democratic residents of County 1: 62.1%.
- Total Republican residents: 58.9%.
- Total Democratic residents: 41.1%.
<h3>What is a relative frequency?</h3>
A relative frequency is given by the<u> number of desired outcomes divided by the number of total outcomes</u>.
In County 1, we have that there are 6,520 residents, out of which 4,050 are Democratic and 2,470 are Republican, hence the relative frequencies are given as follows:
- Republican residents of County 1: 2470/6520 = 37.9%.
- Democratic residents of County 1: 4050/6520 = 62.1%.
In total, there are 24,505 residents, out of which 10,075 are Democratic and 14,430 are Republican, hence the relative frequencies are given as follows:
- Total Republican residents: 14430/24505 = 58.9%.
- Total Democratic residents: 10075/24505 = 41.1%.
