Answer:
95
Step-by-step explanation:
If the mean is 400 and the standard deviation 12.5. It means that a range between 375 and 425 is the mean +- 2 standard deviations
400 - 12.5*2 = 375
400 + 12.5*2 = 425
Which means the probability is 95%
When you are looking for +- 1 deviation standard the probability is 68, and for +- 3 the probability is 99.7
There is a more complex explanation based on Z, but assuming you are only applying 68-95-99.7 rule this should be enough.
Answer:
1) Not congruent
2) AAS
3) Not congruent
4) SAS
5) SSS
6) ASA

The incorrect answer is 6.5 /50
Everything else calculates out to 0.125 pounds of lasagna per serving however the 6.5/50 calculates ti 0.13.
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -7 and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at </span></span>A(-7,-1), passing through P(8, 7) is :
(x+7)² +(y+1)² = 289
The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15 or y+1 = -15
y = 14 or y = -16
you have two points : (-15,14) , (-15, -16)</span>
