A machine is shut down for repairs if a random sample of 100 items selected from the daily output of the machine reveals at least 15% defectives. (Assume that the daily output is a large number of items.) Suppose that a random sample of 20 items is selected from the machine. If the machine produces 5% defectives, find the probability that the sample will contain at least three defectives, by using the following methods.

Chris said that a fraction equivalent to 9/12 is 3/6

Answers

Answer:

9/12 is equal to 3/4.

Step-by-step explanation:

9 and 12 can both be divided by 3. In the fraction, divide both the top and the bottom by 3 and you get 3/4.

9/12 simplified is 3/4.

I suspect where Chris went wrong was that he though 9 divided by 2 was 3. In reality, it's 4.5.

Maybe he went wrong because he accidentally divided 12 by 2 instead of 3.

The fraction 9/12 and 3/6 are not equivalent as 91/2 is 3/4.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Chris said that a fraction equivalent to 9/12 is 3/6.

We know we write fractions in the simplest form.

Now, In the fraction 9/12 we can factor out 3 to both the numerator and the denominator.

Therefore, The fraction 9/12 is equivalent to 3/4.

The cost of 12 oranges and 7 apples is 5.36. Eight oranges and 5 apples cost 3.68. Find the cost of each

Answers

Answer:

Apple costs $0.26

and orange costs $0.32

sorry i don't have time to explain but if u have doubts don't hesitate to ask

Make two equations
O = orange, A = allele
(12O + 7A = 5.36) 2
(8O + 5A = 3.68) 3
Make one of them same coefficient
24O + 14A = 10.72
24O + 15A = 11.04
Subtract both equations
-1A = -0.32
A = 0.32
24O + 14(0.32) = 10.72
24O + 4.48 = 10.72
24O = 6.24, O = 0.26
Solution:
One apple = $0.32
One orange = $0.26

Answers

The correct answer is A.

The area of the square with a side length of 19 meters is 361 square meters.

To determine the area of a square, you multiply the length of one side by itself.

In this case, the side length is given as 19 meters.

To calculate the area of a square, you can use the formula:

Area = side length × side length

Area = 19 meters × 19 meters

Area = 361 square meters

So, the area of the square with a side length of 19 meters is 361 square meters.

C In circle K, segment is tangent to the circle at point A. If the radius of the circle has a length of 5 units and the tangent has a length of 12 units, then what is the length of ?

Answers

The length of segment BC is approximately 10.92 units.

To find the length of segment BC, we can use the properties of a tangent to a circle.

In a circle, a tangent is perpendicular to the radius drawn to the point of tangency. Therefore, triangle ABC is a right triangle with AB as the hypotenuse.

Given that the radius of the circle is 5 units and the tangent AB has a length of 12 units, we can apply the Pythagorean theorem to find the length of segment BC.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (AB) is equal to the sum of the squares of the lengths of the other two sides (BC and AC).

Applying the theorem to triangle ABC:

AB^2 = BC^2 + AC^2.

Substituting the given values:

12^2 = BC^2 + 5^2.

144 = BC^2 + 25.

Rearranging the equation:

BC^2 = 144 - 25.

BC^2 = 119.

Taking the square root of both sides:

BC = √119.

Therefore, the length of segment BC is approximately equal to √119 units.

Since it's not possible to represent the square root of 119 exactly as a whole number or fraction, we can leave the answer as √119 or approximate it as a decimal. The decimal approximation for √119 is approximately 10.92.
