13. A factory produces 500,000 nails per day. The manager of the factory estimates that there are less than 1,500 misshapen nails made per day. A random survey of 500 nails finds 4 misshapen ones. Is the manager correct in his estimate? Explain.

Answers

Answer 1

Answer:

Answer: The manager is incorrect.

Step-by-step explanation: 500,000 nails/500 nails = 1,000 nails. If a survery of 500 nails finds 4 misshapen ones, we must multiply 4 by 1,000 because multiplying 500 by 1,000 gives us 500,000. 4x1,000+4,000. 4,000 does not equal 1,500, so the manager is incorrect.

the product of 8 and a number x is equal to 32. write an algebraic expression, an equation, or an inequality

Answers

The product of 8 and a number x is equal to 32 is 4.

What is product?

A product is the result of multiplication or an expression that identifies the objects (numbers or variables) to be multiplied, called factors.

The order of multiplication of real or complex numbers does not affect the product. this is called the commutative law of multiplication. When multiplying matrices or terms of several other associative algebras, the product usually depends on the order of the factors. For example, matrix multiplication is noncommutative, as is multiplication in other algebras in general.

Given:

so the product of the two numbers (8 and x) IS equal to 32,

8x=32

x = $(32)/(8)$

x = 4

To learn more about product, refer;

The product means multiply, so the PRODUCT of the two numbers (8 and x) IS equal to 32, so...
8x=32
(-Divide 8 on both sides to isolate the variable)
x=4
(Your result is x=4) :-)

Answers

The solution of this equation is -7.
3x - 7 = 4x
3x - 7 - 4x = 0
3x - 4x - 7 = 0
-x - 7 = 0
-x = 7
x = -7

3x-7=4x
3x-4x=7
-x=7 |*(-1)
x=-7
