Answer:
6
Step-by-step explanation:
Here, we are told to find the length of EB
Since the chords AB and CD are both 5 units(equidistant) away from the center of the circle, then we can conclude that they are both congruent and thus are equal in length
Now we use a circle theorem to solve for the length EB
The theorem is that a line that joins the center of a circle to a chord makes a perpendicular angle with the chord and splits the chord into 2 equal parts.
Now we can say that; AB = AE + EB so we split 12 into 2 which is 6 units and that is the length of EB
Answer:
y=10.75
Step-by-step explanation:
46 + 1) + y = 5(y - 1) +9
47+y=5y-5+9
47+y=5y+4
Collect like terms
47-4=5y-y
43=4y
Divide by 4
43/4=4y/4
43/4=y
y=10.75
Answer:At 95% confidence interval, the lower end is 64.306 and the upper end is 64.614
At 98% confidence interval, the lower end is 64.268 and the upper end is 64.652
Step-by-step explanation:
Ittttts obviously be greater than 3/5
5 * 3/5 to get 3!!
