Answer:

See below

Step-by-step explanation:

-[-(11-22)]=-[-(-11)]=-[11]= \large\boxed{-11}

$ \left( \frac{3}{2} \right) \cdot \left(-\frac{22}{33} \right) = -\frac{66}{66}=\large\boxed{-1} $

$\frac{4^2}{5^2}=\large\boxed{\frac{16}{25}}  $

$-\frac{4}{3} -\frac{4}{13} =  -\frac{4 \cdot 13}{3 \cdot 13} -\frac{4 \cdot 3}{13 \cdot 3} = -\frac{52}{39} -\frac{12}{39} = \large\boxed{-\frac{64}{39}} $

$\sqrt{\frac{27}{3} } =\sqrt{9} =\large\boxed{3}$

Write the following numbers used in these statements in scientific notation. (Note: Some of these numbers have been rounded.)
lutik1710 [3]

Answer:

So in scientific form 4000 miles will be equal to 4\times 10^3miles

Step-by-step explanation:

We have given that radius of earth is 4000 miles

4000 miles can be written as 4×1000

We have to written 4000 miles in scientific form

We know that 1000 can be written in scientific form as 1000=10^3

So 4000miles =4\times 1000=4\times 10^3miles

So in scientific form 4000 miles will be equal to 4\times 10^3miles

g Programs submitted by programs in a computer science course are examined for syntax errors and logic errors. Suppose 36% of al
Llana [10]

Answer:

The answer is below

Step-by-step explanation:

Let S denote syntax errors and L denote logic errors.

Given that P(S) = 36% = 0.36, P(L) = 47% = 0.47, P(S ∪ L) = 56% = 0.56

a) The probability a program contains both error types = P(S ∩ L)

The probability that the programs contains only syntax error = P(S ∩ L') = P(S ∪ L)  - P(L) = 56% - 47% = 9%

The probability that the programs contains only logic error = P(S' ∩ L) = P(S ∪ L)  - P(S) = 56% - 36% = 20%

P(S ∩ L) = P(S ∪ L) - [P(S ∩ L') + P(S' ∩ L)] =56% - (9% + 20%) = 56% - 29% = 27%

b) Probability a program contains neither error type= P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44

c)  The probability a program has logic errors, but not syntax errors =   P(S' ∩ L) = P(S ∪ L)  - P(S) = 56% - 36% = 20%

d) The probability a program either has no syntax errors or has no logic errors = P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44
