Which of the following is true of a histogram? (Check all that apply.)

igor_vitrenko [27]

Answer:

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

A peak is a bar that is higher than the other bars around i

If the graph is symmetrical, the data is evenly distributed.

Write the equation of the graph obtained when the graph of y=1/x is compressed vertically by a factor of 0.25, translated 4 unit

NARA [144]

Answer:

$y=\frac{0.25}{x-4}+3$

Step-by-step explanation:

Notice that we are requested to perform three transformations in order: first a vertical compression (of the variable "y"), second a horizontal shift (affecting therefore the horizontal variable "x"), and lastly a vertical translation (affecting the variable "y")

1) Recall that a vertical compression by a factor 0.25 involves multiplying the full function y(x) by the factor 0.25:

$y=0.25 * \frac{1}{x} \\y=\frac{0.25}{x}$

2) the horizontal translation of 4 units to the right involves subtracting 4 from the variable "x":

$y=\frac{0.25}{x-4}$

3) the vertical translation 3 units up involves adding 3 to the full expression for "y":

$y=\frac{0.25}{x-4}+3$

The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?

seraphim [82]

Answer:

$\frac{5\sqrt{34}}{34}$

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = $\sqrt{a^{2} + b^{2} }$ .

In the equation you'd write that as r = $\sqrt{10^{2} + 6^{2}$ which can be simplified to $\sqrt{136$ .

You end up with $\frac{10}{\sqrt{136} }$ and you simplify this by doing $\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }$ , ending with the result of $\frac{5\sqrt{34}}{\sqrt{34} }$ .

(I also got this answer right on the test.)
