sue stacked one box onto another. the bottom had the height of 2 1/3 feet and the top box had the height of 3 2/3 feet. how tall were the stacked boxes?

Answers

Height of bottom box : - 2 (1)/(3) => 7/3
Height of top box : - 3 (2)/(3) => 11/3

Thus, height of two boxes =

(7)/(3) + (11)/(3) = (18)/(3) => 6ft

Happy to help chodini!

When f(x)= -3,what is x

Answers

The value of x is, -3.

What does the X in a function mean?

  • A function defines one variable in terms of another.
  • The statement "y is a function of x" (denoted y = y(x)) means that y varies according to whatever value x takes on.
  • A causal relationship is often implied (i.e. "x causes y"), but does not *necessarily* exist.

What is the value for X?

  • Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division.
  • To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.
  • Simplify the values to find the result.

How are the functions y x?

  • The phrase "y is a function of x" means that the value of y depends upon the value of x, so: y can be written in terms of x (e.g. y = 3x ).
  • If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x"s by 4"s .

What is the value of the product (3 - 2i)(3 + 2i)

Answers

Answer:

13

Step-by-step explanation:

(3 - 2i)(3 + 2i)

FOIL

first  3*3 = 9

outer 3*2i = 6i

inner -2i*3 = -6i

last  -2i * 2i = -4i^2 = -4(-1) =4

Add together

9+6i-6i+4 = 13

The Greens Manufacturing Company makes 60% of a particular type of camera lens, the Parsons Company makes 15% of them, and the Ratten Company makes the remaining 25%. Of all the camera lenses, 5% are made by Greens and are defective, 10% are made by Parsons and are defective, and 6% are made by Ratten and are defective.. . . Lens Defective Not Defective Total .
Greens 5% 55% 60% .
Parsons 10% 5% 15% .
Ratten 6% 19% 25% .

If a camera lens is randomly selected from the general population of all lenses, what is the probability that it was NOT made by the Ratten Company, given that it is defective?



0.22



0.36



0.49

Answers

Answer:

The probability is:

                              0.71

Step-by-step explanation:

Let A denote the event it is defective

and B denote the event that it is not made by Ratten company.

             Lens Defective     Not Defective     Total .  

Greens          5%                          55%             60% .  

Parsons        10%                         5%               15% .  

Ratten            6%                          19%              25% .

Total               21%                        79%             100%

P(A)=0.21

( Since 21/100=0.21 )

P(A∩B)= 15%

( Since,  5%+10%=15%

and 15%/100%=0.15)

Hence, we are asked to find P(B|A)

We know that:

P(B|A)=(P(A\bigcap B))/(P(A))\n\n\nP(B|A)=(0.15)/(0.21)\n\n\nP(B|A)=(15)/(21)\n\n\nP(B|A)=0.71

                   The answer is:

                           0.71
