Answer:
ED = 6.5 cm
BE = 14.4 cm
Step-by-step explanation
AB/BC = AE/ED is less than or eqauls ED = BC×AE/AB
so
ED = 5×26/20 = 130/20 = 6.5 cm
and
AB/AC = BE/CD => BE = AB×CD/AC
so
BE = 20×18/25 = 360/25 = 14.4 cm
There should have been an attached image.
Area of a circle is can only be computed when the radius or diameter is provided.
Area of a circle = π r²
Based on the image I saw, the radius is 5.6 inches
A = 3.14 * (5.6in)²
A = 3.14 * 31.36 in²
A = 98.47 in² ⇒ CHOICE D. 98.5 square inches.

Answer:
a) The confidence interval is 
.
Step-by-step explanation:
We have to calculate a confidence interval (CI) of a difference of proportions.
For the existing procedure, the proportion is:
For the new procedure, the proportion is:
To calculate the CI, we need to estimate the standard deviation
For a 90% CI, the z-value is 1.64.
Then, the CI is:
