To find this, you will take the area of a circle minus area of a square.

Area of a circle: pi• r^2

R is the radius. The radius is half of a diameter. Divide 11 by 2 to get 5.5.

Keep in mind that the instructions says to use 3.14 instead of the pi button so you will just use that instead of pi.

A = (3.14)(5.5^2)
A= (3.14)(30.25)
A= 94.985

A square has the same side lengths, so you would just multiple 8 by 8 to get 64.

Area of a triangle minus area of a square:
94.985-64

= 30.985 ft^2.

** Area will always be squared.

Answer:

About 316.13

Step-by-step explanation:

We know:

Diameter (d) = <u>11</u> (of the circle)

Area of the circle: pi(11)^2 = <u>121pi </u>

Side of the square = <u>8 </u>

so area of the square is 8^2 = <u>64</u>

Area of the shaded region:

121pi-64 =316.13

hope this helped

The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.1

Anika [276]

Answer:

0.3 probability that $x \leq -3$

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x <= -3

The values that are -3 or lower are -3 and -5. So

$P(X \leq -3) = P(X = -3) + P(X = -5)$

From the table:

$P(X = -3) = 0.13, P(X = -5) = 0.17$ . So

$P(X \leq -3) = P(X = -3) + P(X = -5) = 0.13 + 0.17 = 0.3$

0.3 probability that $x \leq -3$

Another inequality question :( Can someone help pls??<br> Thanks :D

Klio2033 [76]

Answer:

$y\geq x$

Step-by-step explanation:

Again, let us begin by finding the equation of the line

The y-intercept is 0 and the slope is 1, so the equation of this line would be $y=x+0$ or just $y=x$

We can see that the shaded region is ABOVE the line, so we would use a greater than (>) sign.

This as the line is shaded in, we must also include that line in the inequality. This means that we will instead use the $\geq$ sign.

This means that our answer would be $y\geq x$
