Answer:
1. r=17
2. (-15,14) or (-15,-16)
Step-by-step explanation:
The radius of the circle is the distance from the center to the point on the circle, thus

The equation of the circle is

If point lies on this circle, then its coordinates satisfy the circle's equation:

X - 3 = -5........addition property....because u add -3 to both sides
6x = 72.....either division property...because u divide both sides by 6.
or multiplication property...because u multiply both sides by 1/6
x/5 = 3.....multiplication property....because u multiply both sides by 5
7. A. -18 cm, because it changes -3 cm/per year, so multiply 6 years by -3 cm to get -18 cm
8. D. $20, because it rose +$2 over 10 days, you multiply 10 days by $2 to get $20 total
Answer: Option "B" is correct.
Step-by-step explanation:
Since we have given that
α= 0.10
Let the population variances are equal and samples are random and independent.
Let
be the mean amount spent by a customer at Burger Stop.
Let
be the mean amount spent by customer at Fry World.
So, it has given that
the mean amount is spent by a customer at Burger stop is greater than the mean amount spent by a customer at Fry World.
So, Hypothesis would be :

Hence, Option "B" is correct.
This the concept of circumference of circle. The arc length will be given by:
C=theta/360*pi*diameter
theta=62
diameter=d
thus the arc length will be:
C=62/360*π*d
C=0.54d
