Answer:

We are finding hypotenuse

3^2 + 2.5^2

9 + 6.25 = 15.25

3.9^2 = 15.21 close enough.

3.9 would be your answer.

When finding the hypotenuse, we square the two given lengths add them up and then that number you get from adding them up, there should be a number that will be squared that will equal that number that you added up.

Answer:

$\large\boxed{\large\boxed{10/21}}$

Explanation:

There are only two mutually exclusive possibilities for each complex electronic system: being defective or being not defective:

Number of complex electronic systems: 7
Nmber of defective systems: 2
Number of not defective systems: 5

Probability that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:

Porbability the first is not defective × probability the second is not defective

5/7 × 4/6 = 20/42 = 10/21

The ratio of students who wear glasses to the total number of students in the class is 2:5 if there are 14 students who wear gla

vazorg [7]

Answer:

35 students in the class.

Step-by-step explanation:

If there are 5 students in the class, then 2 of them would wear glasses and 3 of them wouldn't. (Equation 1)

Now, there are 14 students how are wearing glasses.

We just times the whole Equation 1 by 7.

If there are 5 x 7 = 35 students in the class, then 2 x 7 = 14 of them would wear glasses and 3 x 7 = 21 of them wouldn't.

So, there are 35 students.
