Answer:
x = 11.5
Step-by-step explanation:
![\sin \: 35 \degree = \frac{x}{20} \\ \\ x = 20 \sin \: 35 \degree \\ \\ x = 11.471528727 \\ \\ x = 11.5](https://tex.z-dn.net/?f=%20%5Csin%20%5C%3A%2035%20%5Cdegree%20%3D%20%20%5Cfrac%7Bx%7D%7B20%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2020%20%5Csin%20%5C%3A%2035%20%5Cdegree%20%5C%5C%20%20%5C%5C%20x%20%3D%2011.471528727%20%5C%5C%20%20%5C%5C%20x%20%3D%2011.5)
No this number is not written in scientific notation
In scientific notation, it'll look like
4.8 * 10 ^14
In scientific notation it's 10 ^ n
NOT 100^n
Hope this helps
2 3/4 = 11/4
4 1/8 = 33/8
11/4 / 33/8 = 11/4 * 8/33 = 88/132 = 2/3

Answer:
Confidence interval for the population proportion of women fearing from breast cancer are 61%
Step-by-step explanation:
Point estimate of the proportion of the population of women who feared from breast cancer is:
β=61%
Standard error of the estimate:
Se= 0.154
Margin of error for 90% confidence interval for the population proportion:
0.254
90% confidence interval for the population proportion will be
(0.5846,0.6354)
