Answer:
142125
Step-by-step explanation:
Since we given two brackets to solve we will have to take the step by step procedure
So let's solve the question
(2+377)(2-377)
Let's start with the first bracket
(2+377)
It will give us 379
So let's solve the second bracket
(2-377)
It will give us -375
So back to the question
(379)(-375)
142125
So the final answer is 142125
Answer:
The center is (5, -2) and the radius is 9/2
Step-by-step explanation:
The equation of a circle can be written by
(x-h) ^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-5)^{2}+(y+2)^{2} = 81/4
( (x-5)^{2}+(y- -2)^{2} = (9/2)^2
The center is (5, -2) and the radius is 9/2
Answer:
Option E
Step-by-step explanation:
This survey will not be reliable as it is chosen for convenience; the first 120 students to arrive in school on a particular morning and this collection of individuals may not be a representative of the population. The study may become biased because it does not take into account the latecomers among the students which might have been changed the study from systematically favoring certain outcomes.
