Cans of peas are sold with a label indicating 21 ounces by weight. In fact, the actual weight varies from can-to-can. The weight follows a Normal distribution with a mean of 21 ounces and a standard deviation of 1 ounce. What is the probability that a can contains between 19 and 20 ounces of peas

what is

step-by-step explanation:

probably .5

i can on others if necessary.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
