Answer:
Answer choice A(57%)
Step-by-step explanation:
The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)
the answer is probably sas, but im just guessing cuz there's like no context whatsoever in the picture.
Answer:
r=20
Step-by-step explanation:
34-2=32 32 - 12 =20 r= 20
Answer:
![P (X = 140) = 0](https://tex.z-dn.net/?f=P%20%28X%20%3D%20140%29%20%3D%200)
Step-by-step explanation:
We know that the heron wingspan follow a normal distribution with an mean of 125 cm.
In this case we seek to find
![P (X = 140)](https://tex.z-dn.net/?f=P%20%28X%20%3D%20140%29)
If X is a random variable that represents the length of the heron wingspan, then X follows a normal distribution and therefore is a continuous random variable.
Then by definition of continuous random variable we have to:
where a is a constant.
That is to say that only the ranges of values can have a different probability of zero. The probability that a continuous random variable is equal to some exact value is always zero.
Finally we can conclude that
![P (X = 140) = 0](https://tex.z-dn.net/?f=P%20%28X%20%3D%20140%29%20%3D%200)
Answer:
c.s.a of cone = pie r^2 + pie r l
radius = diameter/2 = 13/2
slant height (l) = 17
pie (13/2)^2 + pie 13/2 * 17
3.14 * 169/4 * 3.14 * 13/2 * 17
368246/8
= 46030
