Someone help me with example plzz

kati45 [8]

Answer:

Angle JML= 132( given)

Triangle JML= 180( Angle sum property)

2x+ 48= KML( Exterior angle property)

In triangle JML,

76 + ∠L+ ∠KML=180°

∠KML=∠L( angles opposite to equal sides are equal)

76+2(2x+48)=180°

2(2x+48)=104°

2x=104-48=64°

x= 32°

Step-by-step explanation:

Hope it helps : )

Of the coffee makers sold in an appliance store, 4.0% have either a faulty switch or a defective cord, 2.5% have a faulty swi

lukranit [14]

Answer: Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.

Step-by-step explanation:

Since we have given that

Let A be the event of getting a faulty switch.

Let B be the event of getting a defective cord.

Here, P(A∪B) = 4% = 0.04

P(A∩B) = 0.1% = 0.001

P(A) = 2.5% = 0.025

We need to find P(B):

As we know that

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\0.04=P(A)+0.025-0.001\\\\0.04=P(A)+0.024\\\\P(A)=0.04-0.024=0.376$

Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.
