The employees of a company were surveyed on questions regarding their educational background (college degree or no college degre

taurus [48]

Answer: D) 0.733.

Step-by-step explanation:

Let C denotes the number of employees having college degree and S denote the number of employees are single.

We are given ,

Total = 600 , n(C)=400 , n(S)=100 , n(C∩S)=60

Then,

$n(C\cup S)=n(C)+n(S)-n(C\cap S)\\\\=400+100-60=440$

Now, the probability that an employee of the company is single or has a college degree is

$P(C\cup S)=\dfrac{n(C\cup S)}{\text{Total}}\\\\=\dfrac{440}{600}=0.733333333\approx0.733$

Hence, the probability that an employee of the company is single or has a college degree is 0.733

Since SSS guarantees that two triangles are congruent, one might think that SSSS guarantees that two quadrilaterals are congruen

timurjin [86]

Answer:

Below.

Step-by-step explanation:

When you graph this you'll see that it is a rhombus, which has 4 equal sides and the 4 angles are not 90 degrees.

You could draw a square on the coordinate plane using A(0.0). B (0,3), C(3,3) and D(3,0). The sides of the square are all equal to the sides of the rhombus but the 2 quadrilaterals are not congruent because the angles have different values,

the slipperiness of a floor (demoted by S) can be defined as a function of the number or banana peels (denoted by P) and the are

QveST [7]

We have been given that the slipperiness of a floor (demoted by S) can be defined as $S=\frac{P}{A}$

Here P= number or banana peels

A=area of the floor

Number of bananas peels can be measured (units ) in peels

Area can be measured in $m^2$

Since, slipperiness of a floor is the ratio of these two hence, we have

$\text{slipperiness of a floor}=\frac{\text{Peels}}{m^2}$

A is the correct option.
