The answer is option E i.e., 1 because we know that there are 3 defective batteries in the case so the probability will never be 1 for this case.

When you ask a question the answerer gets your points. So when you give a brainliest do you lose one of your own brainliests? So

No, when you give someone points for answering your question it takes them from you but when you give someone brainliest it doesn't take the ones you recieved already for some reason

Eli attended a concert. The decibel level of the music averaged 110 decibels but varied by 28 decibels from the average. Enter a
musickatia [10]

Answer:

The decibel range is   82\leq d\leq 138

Step-by-step explanation:

Let

d -----> the decibel level of the music

we know that

The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels

so

The absolute value that represent this problem is

\left|d-110\right|\le28

Solve the absolute value

<em>First solution (positive)</em>

+(d-110)\le28

Adds 110 both sides

d\le28+110

d\le138

<em>Second solution (negative)</em>

-(d-110)\le28

Multiply by -1 both sides

(d-110)\ge-28

Adds 110 both sides

d\ge-28+110

d\ge82

therefore

The decibel range is

82\leq d\leq 138

Bond [772]

Answer:

PQ = 28 cm

QR = 21 cm

Step-by-step explanation:

PQ = PS + SQ = 16 + 12= 28

QR = QS + SR = 12 + 9 = 21
