Find the value of x.
poizon [28]
We know that
Sum of angles in triangle = 180°
let third angle be Y

Now ,
60+74+Y = 180

=> 134 + Y = 180

=> Y = 46°

Now to find X

We know that angle made by straight line is 180°

So now ,
Third angle + x = 180°

=> 46 + x = 180

=> x = 180 -46
=> x = 134°

On the average,1% of a specific engine componentis found to not perform to standards when tested at the engine assembly plant. F
sasho [114]

Answer: 0.07938

Step-by-step explanation:

Let X be  a binomial variable that represents the components of a specific engine.

As per given , the probability of componentis found to not perform to standards : p= 1%=0.01

Binomial probability formula :

P(X=x)=\ ^nC_xp^x(1-p)^{n-x}

Sample size : n= 100

If more than two are found to be non-performing the entire shipment is returned.

Now, Required probability : P(X>2)=1-P(X\leq 2)

=1-(P(X=0)+P(X=1)+P(X=2))\\\\=1- (^{100}C_{0}(0.01)^0(0.99)^{100}+^{100}C_{1}(0.01)^{1}(0.99)^{99}+^{100}C_{2}(0.01)^{2}(0.99)^{98})\\\\=1-((0.99)^{100}+(100)(0.01)(0.99)^{99}+\dfrac{100!}{2!98!}(0.01)(0.99)^98)\\\\=1-(0.36603+0.36973+0.18486)\\\\=1-(0.92062)\\\\=0.07938

So, the probability that a shipment is returned = 0.07938
