It looks like you want to find the height of the green region. If so then that would be about 5.2 mL since the top part of the green area is around the first smaller tick above the 5.

Each smaller tickmark is 1/5 = 0.2 of a full unit. Note how there are 5 smaller tickmark spaces to make up a full unit (when we go from 5 to 6, there are 5 smaller tickmark spaces we have to move)

<h3>Answer: 5.2  mL</h3>

An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (An ordinary (fair) coin is tossed 3 times. Ou)
shepuryov [24]

Answer:

Probability distribution

X    P(X)

0    1/8

1     3/8  

2    3/8

3     1/8

Step-by-step explanation:

When a coin is tossed there are two outcomes head and tail. When three coins are tossed the possible outcomes are

Sample space=S={HTH,THH,TTH,HHH,HTT,THT,TTT,HHT}

The total number of outcomes is n(S)=8. The X be the random variable counting number of tails in each outcome and so X can take values as 0,1,2,3. The probabilities can be computed as P(X)=n(X)/n(S). The probabilities are calculated as under:

X   Outcomes           P(X)

0    HHH                    1/8

1     HHT,THH,HTH    3/8  

2    TTH,HTT,THT     3/8

3    TTT                        1/8

The probability distribution of X is as under:

X    P(X)

0    1/8

1     3/8  

2    3/8

3     1/8

(Retry) Which of the following simplifies to a negative number? <br> -- It isn't C, apparently.
Simora [160]

Answer:

The answer would be A, -4^{-4}

Step-by-step explanation:

Remember, x^{-n} ≠ -x^{n}, x^{-n} = \frac{1}{x^{n} }.

a = -4^{-4} = -(4^{-4})

a = -\frac{1}{4^{4} }

a = -\frac{1}{256}

-\frac{1}{256} is negative

-\frac{1}{256} = -4^{-4}, so -4^{-4} is negative

The function f(x) = (x - 4)(x - 2) is shown below. What is true about the domain and range of the function?​
Arlecino [84]

Answer:

Dom\{f(x)\} = \mathbb{R} (Since polinomial functions are continuous)

Ran\{f(x)\} = [-1, +\infty) (As this quadratic function has an absolute minimum, represented by its vertex)

Step-by-step explanation:

Graphically speaking, quadratic functions are represented by parabolas. In this case, we have a parabola in factorized form. From Theory of Functions, we get that domains of function represents the set of values of x so that exist an image, whose set is known as range is represented by values of f(x).

x is represented by horizontal axis in the figure, whereas f(x) is represented by the vertical axis. By using this approach we get that domain and range of the function are, respectively:

Dom\{f(x)\} = \mathbb{R} (Since polinomial functions are continuous)

Ran\{f(x)\} = [-1, +\infty) (As this quadratic function has an absolute minimum, represented by its vertex)
