Which function could be a stretch of the exponential decay function shown on the graph?
dezoksy [38]

Answer:

f(x) = (\frac {1}{2})^{(6x)}

Step-by-step explanation:

The given options are,

a) f(x) = 2^{(6x)}

b) f(x) = (\frac {1}{2})^{(6x)}

c) f(x) = 2 \times (\frac {1}{6})^{x}

d) f(x) = \frac {1}{2} \times (\frac {1}{6})^{x}

Now, clearly a) is a monotonically increasing function, hence discarded, and both of c)  and d) don't pass through (0, 1) hence they are also discarded.

Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.

What is the length for the 3rd side? write in simplest radical form if needed
9966 [12]

Answer:

10

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

Let the third side be x , then

x² + 6² = (2\sqrt{34} )²

x² + 36 = 136 ( subtract 36 from both sides )

x² = 100 ( take the square root of both sides )

x = \sqrt{100} = 10

Of all vehicles sold by a certain car dealership, 35% are sports cars. From 50 randomly selected vehicle purchases, use the norm
PolarNik [594]

Answer:

a) 0.1178

Step-by-step explanation:

The calculation is shown below:-

Mean = np

= 50 × 0.35

= 17.5

Standard deviation is

= \sqrt{n\times p\times q}

= \sqrt{50\times 0.35 \times 0.65}

= 3.373

Therefore, as we know that

P which is Less than 14

So,

= P(X < 13.5)

= P(z < (13.5 - 17.5) ÷ 3.373

= P(z < -1.186)

= 0.1178

Hence, the correct option is a. 0.1178

basically we used the above formulas i.e mean and standard deviation
