The answer is d. I got that by adding 1/3 + 1/3 + 1/3 + 1/2 + 2/3 = 2 1/6
Answer:
14.13 cubic inches
Step-by-step explanation:
Given: The diameter of an entire coconut is 5 inches, and the coconut meat is 1 inch thick.
To find: radius and volume of the inside sphere
Solution:
Diameter of an entire coconut = 5 inches
Radius of an entire coconut (R) = diameter/2 =
Radius of the inside sphere coconut (r) = 2.5 - 1 = 1.5 inches
Volume of inside sphere =
= cubic inches
Answer:
a. Yes. This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.
b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error. A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected. While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.
Step-by-step explanation:
Total number of attendees who ordered fish = 1,000
Sample size of the attendees who ate fish = 80
Number of attendees who ate the fish and got sick = 64 (80% or 64/80)
Sample size of attendees who did not eat fish = 60
Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)
The slope is the number before the variable x, so the slope is -1/2.
To answer this question, you will multiply the chance of NOT having english homework (100-70=30% chance) by the chance of her NOT having math homework (100-60=40%).
This would be 0.3 x 0.4=0.12 or 12% chance of both occurring.
