Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?

Answers

Answer 1

Answer:

12 inches

Step-by-step explanation:

1 x 4 = 4

16 - 4 = 12

Answer 2
Answer:

Snow after 4 hours: 16 Show after t hours: -1t

Step-by-step explanation:

Snow after 4 hours:

starting amount =  16

melted snow=   inches per hour×4

=1×4

=

4

final amount=  starting amount−melted snow

=  16−4

=12

​

Snow after t hours:

starting amount=  16

melted snow=  inches per hour×t

=1×t

=1t

final amount=  starting amount−melted snow  =16-1t

R and T are two mutually exclusive events.
P(R) = 0.2 and P(R or 1) = 0.69
Work out P(not T).

Answers

Answer:

P(not T ) =  0.51

Step-by-step explanation:

Step(i):-

Given that the R and T are two mutually exclusive events

P(R∩T) = 0

Addition theorem on probability

P(RUT) =P(R)+P(T) - P(R∩T)

P(RUT) =P(R)+P(T) - 0

P(RUT) =P(R)+P(T)

Step(ii):-

Given P(R) = 0.2 and P(RUT) = 0.69

P(RUT) =P(R)+P(T)

P(T) =  P(RUT) -P(R) = 0.69 -0.2

P(T) = 0.49

P(not T) = 1- P(T)

P(not T ) = 1 - 0.49 = 0.51

Final answer:-

P(not T ) =  0.51

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that  guitar factory has a cost of production C(x)=75x+50000. If the company needs to break even after 150 units sold, then;

C(x)=75x+50000

75x + 50000 = 150x

C(x)= 50000 = 75x

x = 50000/75

x = 666.67

Therefore, The price of the each guitar would be; 666.7 rounded to the nearest greatest cent.
