Write down an (in)equality which describes the solid ball of radius 2 centered at (-2, 5, 2). It should have a form like ????2 ?

MissTica

$\text{We know that the euation of the sphere with radius r and centered at (h,k,l)}\\
\text{is given by:}\\
\\
(x-h)^2+(y-k)^2+(z-l)^2=r^2\\
\\
\text{here we have given a solid ball of radius 2 centered at }(-2, 5,2), \text{ so the }\\
\text{region of the ball will be all the area within the ball.}\\
\text{Hence the inequality that will describe the ball is give given by}$

$(x-(-2))^2+(y-5)^2+(z-2)^2\leq 2^2\\
\\
\Rightarrow (x+2)^2+(y-5)^2+(z-2)^2\leq 4\\
\\
\text{hence the required inequality that describes the ball is:}\\
\\
(x+2)^2+(y-5)^2+(z-2)^2-4\leq 0$

In a large class of introductory Statistics students, the professor has each person toss a coin 16 times and calculate the propo

Leni [432]

Answer:

<u>A slope of 0.5.</u>

Step-by-step explanation:

Each coin toss has a 50% probability of being heads. Therefor, the histogram plot should have a slope of 0.5. To illustrate, graph the predicted probabilities of at least two sets of coin tosses, such as 6 and 16. The probable number of heads would be 3 and 8. Plot those two points and draw the line. <u>The slope of that line will be 0.5.</u>

See the attachment. I graphed more than two points, since it was easy. But you really only need two if you know it is a straight line function. Graph a third just to be certain.

GalinKa [24]

Answer:

Step-by-step explanation:

solution

variables are

Number of shirts made and number of pajamas made

and

constraints are

fabric in yd and time in hr

and

inequalities for the constraints are

we consider here

no of shirt = x

no of pajama = y

x ≥ 0 and y ≥ 0

x +2y ≤ 1000

2x +3y ≤ 1600
