Answer: very too bad for you buddy study nexts time
Step-by-step explanation:
Product means the answer/result to a multiplication problem
Estimate means to form an approximation/ rough guess
126.12 x 2.2 = 277.464
This answer, 277.464, is the exact product
Its wanting us to find the estimate (there could be possible estimates, depending on what the instructions is asking for):
- 277
- 280
- 300
Answer:
153.94
Step-by-step explanation:
AB=πr2=π·72≈153.93804
Variance is the standard deviation squared but we're not going to use that now. Let's first calculate the mean:
mean = (17+13+13+22+11+20)/6 = 16.
Now for each value, let's see how far it is from this mean. We'll square these distances and average them. That's our variance.
17 distance 1 squared = 1
13 distance 3 squared = 9
13 distance 3 squared = 9
22 distance 6 squared = 36
11 distance 5 squared = 25
20 distance 4 squared = 16
Now average these outcomes:
variance = (1+9+9+36+25+16)/6 = 16.
So the variance by coincidence is the same as the mean.
Answer C is your answer.
Answer:
The point of intersection with the x axis are (-2,0) and (8,0)
Step-by-step explanation:
given circle equation x²+y² = 25
x² + y² = r²
r is the radius.
✓(25) = 5
given the center is at (3,0) and radius of 5
(3+5,0) and (3-5,0)
(8,0) and (-2,0)
