16. From past experience, a company has found that in cartons of transistors, 92% contain no defective transistors, 3% contain o
Lynna [10]

Answer:

E(x)=0.15

V(x)=0.3075

S(x)=0.5545

Step-by-step explanation:

The mean of a discrete variable is calculated as:

E(x)=x_1*p(x_1)+x_2*p(x_2)+...+x_n*p(n)

where x_1,x_2,...,x_n are the values that the variable can take and p(x_1),p(x_2),...,p(x_n) are their respective probabilities.

So, if we call x the number of defective transistors in cartons, we can calculate the mean E(x) as:

E(x)=(0*0.92)+(1*0.03)+(2*0.03)+(3*0.02)=0.15

Because there are 0 defective transistor with a probability of 0.92, 1 defective transistor with a probability of 0.03, 2 defective transistors with a probability of 0.03 and 3 defective transistors with a probability of 0.01.

At the same way, the variance V(x) is calculated as:

V(x)=E(x^2)-(E(x))^2

Where E(x^2)=x_1^2*p(x_1)+x_2^2*p(x_2)+...+x_n^2*p(n)

So, the variance V(x) is equal to:

E(x^2)=(0^2*0.92)+(1^2*0.03)+(2^2*0.03)+(3^2*0.02)=0.33\\V(x)=0.33-(0.15)^2\\V(x)=0.3075

Finally, the standard deviation is calculated as:

S(x)=\sqrt{V(x)} \\S(x)=\sqrt{0.3075} \\S(x)=0.5545

Find the number of all the 3-digit numbers which are divisible by 2 but not divisible by 10.
almond37 [142]

Answer:

They're a lot like 104, 212, 526, 618 etc

Step-by-step explanation:

104÷2=52

104÷10=10 with a remainder 4

212÷2=106

212÷10=21 with a remainder 2

526÷2=263

526÷10=52 with a remainder 6

618÷2=309

618÷10=61 with a remainder of 8

Find the area of the circle formed when a plane passes 7 cm from the center of a sphere with radius 8 cm. give your answer in te
Artyom0805 [142]

The area of the circle formed when the plane passes through the center of the given sphere is: 15π cm².

<h3>What is the Area of a Circle?</h3>

Area of a circle = πr² (radius of the circle = r).

Given the following:

  • Radius of sphere = 8 cm
  • Distance of the plane from the center of the sphere = 7 cm

Radius of the circle = √((radius of sphere)² - (distance of the  plane  from  the  center of sphere²)) = √(8² - 7²)

Radius of the circle = 3.87 cm

Area of the circle = π(3.87²) ≈ 15π cm².
