Answer:

40 m²

Step-by-step explanation:

square area = 4x4 = 16 m²

4 triangles area = 4x3x0.5x4 = 24 m²

16 + 24 = 40 m²

Answer:

Point Q lies on the circumference of the circle.

Step-by-step explanation:

We are given a circle with the point C (4,3) as its center with a radius of 3.16 units and we need to figure which of the given point lies on the circumference of the circle.

We can find this by using the distance formula:

Distance between C and P = $\sqrt{(4-2)^2+(3-1)^2} = \sqrt{8} = 2.82$

Distance between C and Q = $\sqrt{(4-7)^2+(3-4)^2} = \sqrt{10} = 3.16$

Distance between C and R = $\sqrt{(4-1)^2+(3-3)^2} = \sqrt{9} = 3$

Since the distance between the points C and Q equals to the radius of the circle, therefore point Q lies on the circumference of the circle.

An optical inspection system is used to distinguish among different part types. The probability of a correct classification of a

IrinaVladis [17]

Answer: Mean = 2.91 and Variance = 0.087

Step-by-step explanation:

Given : The probability of a correct classification of any part p= 0.97.

The number of parts are inspected : n=3

Let the random variable X denote the number of parts that are correctly classified.

For binomial experiment , the mean and variance is given by :-

$\mu=np\\\\\sigma^2=np(1-p)$

Then, the the mean and variance of X will be :-

$\mu=3(0.97)=2.91\\\\\sigma^2=np(1-p)=3(0.97)(0.03)=0.0873\approx0.087\ \ [ \text{Rounded to three decimal places}]$
