![A= ab \frac{sin \theta}{2}](https://tex.z-dn.net/?f=A%3D%20ab%20%5Cfrac%7Bsin%20%5Ctheta%7D%7B2%7D)
where A is area
a is side a lets say its 8cm
b is side b lets say its 7 cm
theta is 28
Firts, Let
![x](https://tex.z-dn.net/?f=x)
be the repeated decimal that we are trying to convert , so
![x=10.9090909090](https://tex.z-dn.net/?f=x%3D10.9090909090)
equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:
![100x=1090.90909090](https://tex.z-dn.net/?f=100x%3D1090.90909090)
(2)
Subtract equation (1) from equation (2):
![100x-x=1090.90909090-10.90909090](https://tex.z-dn.net/?f=100x-x%3D1090.90909090-10.90909090)
![99x=1080](https://tex.z-dn.net/?f=99x%3D1080)
Solve for
![x](https://tex.z-dn.net/?f=x)
![x= \frac{1080}{99}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B1080%7D%7B99%7D%20)
We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>
![\frac{1080}{99}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1080%7D%7B99%7D%20)

Answer:
Step-by-step explanation:
pop 1 n₁ = 260, p₁ = 58% = 0.58
pop 2 n₂ = 260, p₂ = 8% = 0.08
Null hypothesis: p₁ ≤ p₂
Alternative hypothesis: p₁ > p₂
The test statistic : p₁-p₂ / √{p-sample (1 - p-sample) (1/n₁ + 1/n₂)}
where p-sample is sample proportion = p₁n₁ +p₂n₂ / n₁+n₂
Thus, p-sample = 0.58x260 +0.08x260 / 260+260 =150.8+20.8 / 520 = 171.6 / 520 = 0.33.
Thus, the test statistic is (0.58 - 0.08) / √[0.33 (1-0.33) (0.0038+0.0038)
= 0.5 / √[0.33(0.67) (0.0076)
= 0.5 / √0.00168036
= 0.5 / 0.04099
= 12.20
P = P(Z>12.20) = 1-P(Z≤12.20) at a significance level of 0.1= the p-value is less than the hypothesized thus, we have sufficient evidence to reject the null hypothesis and concluding that vinyl gloves have a greater virus leak than latex gloves.
X - 14 = 52
move - 14 for + 14
x = 52 + 14
x = 66
