Answer:
(b) 4,445
Step-by-step explanation:
If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?
Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)
So n=(Z/E)^2*p*(1-p)
=(1.96/0.015)^2*0.5*0.5
=4268.444
Take n=4269
Answer:(b) 4,445
We need to compute for the circumference of the circle and get 75% of the value because only 3/4 of the figure is a circle. 1/4 is substituted by the triangle.
I am assuming that the 35 yards is the radius of the circle.
Circumference = 3.14 * 2 * 35 yards = 219.80 yards
3/4 of the circumference = 219.80 * 3/4 = 164.85 yards
Perimeter = 164.85 yards + 45 yards = 209.85 yards
Ran round the field 3 times.
209.85 yards * 3 times = 629.55 yards
(x-1)+x+(x+1)=915
3x=915
x=305
304, 305, 306
Answer:
The number is 1/4

Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the measure of angle CQJ
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite.


substitute the values


Part 2) Find the measure of angle LIJ
step 1
Find the measure of angle IJL
we know that
The inscribed angle is half that of the arc it comprises.

substitute the values

step 2
Find the measure of angle ILJ
we know that
The measurement of the external angle is the semi-difference of the arcs it encompasses.

substitute the values

step 3
Find the measure of angle LIJ
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
In the triangle LIJ

substitute the values
