Letter F
Because:
1/5 = 2/10
and
1/2 = 5/10
2/10+5/10=7/10
(+24) - (-83) =
24 + 83 = 107
(0.0974, 0.1226)
Step-by-step explanation:
We first find the sample proportion;
255/ 2373
0.11
The Z value for a 95% confidence interval is 1.960
Therefore;
0.11 +- 1.96 * √ (0.11(1 – 0.11))/2373
0.11 +- 1.96 * 0.00642
0.11 +- 0.0126
= 0.1226
= 0.0974
(0.0974, 0.1226)
Answer:
The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is .
Step-by-step explanation:
We are given the area of an Equilateral triangle which is A = . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
So, the area of an equilateral triangle =
where, s = side of an equilateral triangle
A =
Cross multiplying the fractions we get;
Now. moving to the right side of the equation;
Taking square root both sides we get;
Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
