If 400 batteries are tested, about how many are expected to be defective?

29

Step-by-step explanation:

Heer is the complete question:

A factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many are expected to be defective?

A) 14

B) 371

C) 29

D)35

Probability that a battery is defective = 1/14

Number of batteries tested= 400

Expected number of defective batteries= Probability that a battery is defective × Number of batteries tested

= 1/14 × 400

= 400/14

= 28.57

= 29 Approximately

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
