Answer:

Option d.

Step-by-step explanation:

we know that

The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.

The curve is called the probability density function (abbreviated as pdf).

We use the symbol f(x) to represent the curve

therefore

The probability density function f(x) represents . the height of the function at x.

Troyanec [42]

Answer: $9.66\ units$

Step-by-step explanation:

The triangle CDE is shown in the image attached.

The formula for calculate the distance between two points is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Then, we can calculate the lenght of each side of the triangle:

$d_{CD}=\sqrt{(4-4)^2+(-5-(-1))^2}=4\ units\\\\d_{DE}=\sqrt{(4-2)^2+(-5-(-3))^2}=2.828\ units\\\\d_{CE}=\sqrt{(2-4)^2+(-3-(-1))^2}=2.828\ units$

Therefore, the perimeter is:

$P=4\ units+ 2.828\ units+2.828\ units=9.66\ units$

nordsb [41]

Assuming x = dimes, y = quarters

$x + y = 28 \\ 0.1x + 0.25y = 5.20$

$x + y = 28 \\ x = 28 - y$

Substitute that into,
$0.1(28 - y) + 0.25y = 5.20 \\ 2.8 - 0.1y + 0.25y = 5.20 \\0.15y = 2.4 \\ y = 16$

Answer : He has 16 quarters.

Hope this helps. - M
