True.

Because, OAC forms a triangle where:

- the base is AC,
- the other two sides are OA and OC with same length equal to OP (the radius of the circle)
- when you trace the bisectriz of AC you realize it is a line perpedicular to AC that intersects the center of the the circle, O

Suppose the scores of students on a statistics course are normally distributed with a mean of 476 and a standard deviation of 85
soldi70 [24.7K]

Answer: 47.72 %

Step-by-step explanation:

Given : The scores of students on a statistics course are normally distributed with a mean of \mu=476 and a standard deviation of \sigma=85.

Let x be the random variable that represents the scores of students on a statistics course .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 476

z=\dfrac{476 -476 }{85}=0

For x= 646

z=\dfrac{646 -476 }{85}=2

Now, the probability of the students scored between 476 and 646 on the exam will be :-

P(476

Hence, the percentage of the students scored between 476 and 646 on the exam = 47.72 %

What is the general form of the equation of a circle with center at (a, b) and radius of length m?
pochemuha
The equation of a circle with center (h,k) and radius r is
(x-h)^2+(y-k)^2=r^2

convert it to that form by comleting the square for the x and y terms
or, we can just expand what we know

expand (x-a)^2+(y-b)^2=m^2 and make it equal to 0
so expanding we get
x^2-2ax+a^2+y^2-2by+b^2=m^2
minus m^2 from both sides
x^2-2ax+a^2+y^2-2by+b^2-m^2=0
arranging in decreasing power order with m² at the end
x^2+y^2-2ax+-2by+a^2+b^2-m^2=0
that is option A


answer is A
