Answer:
If no units then find the square of 135 to get the answer
Step-by-step explanation:
<u>Answer-</u>
<em>It </em><em>is reasonable</em><em> that the state education department claims the percentage for the entire state is 63%.</em>
<u>Solution-</u>
153 out of the 258 high school students surveyed at a local school said they went outside more during school hours as elementary school students than they do now as high school students.
Here,
x = 153,
n = 258,
Then,

And,

Putting the values,

The interval would be,

As population proportion p=63% lies in this interval, so it is reasonable.
Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
Answer:
4.17% error (i hope)
Step-by-step explanation:
120 - 125 = -5
l -5 l = 5
5/120 = 1/24
1/24 = .0417
