Answer:

(-15, 14)

Step-by-step explanation:

Let the coordinates of Z be (x,y).

$\frac{x+5}{2}=-5 \implies x=-15 \\ \\ \frac{y+6}{2}=10 \implies y=14$

2 point) what is the height of a d-heap that contains n elements? the height should be a function of n and

belka [17]

Assuming a d-heap means the order of the tree representing the heap is d.
Most of the computer applications use binary trees, so they are 2-heaps.

A heap is a complete tree where each level is filled (complete) except the last one (leaves) which may or may not be filled.

The height of the heap is the number of levels. Hence the height of a binary tree is Ceiling(log_2(n)), for example, for 48 elements, log_2(48)=5.58.
Ceiling(5.58)=6. Thus a binary tree of 6 levels contains from 2^5+1=33 to 2^6=64 elements, and 48 is one of the possibilities. So the height of a binary-heap with 48 elements is 6.

Similarly, for a d-heap, the height is ceiling(log_d(n)).

In a certain lake, trout average 12 in. in length with standard deviation 2.75 in. and the bass average 4 lb. in weight with sta

NISA [10]

Answer:

The bass fish was the better catch

Step-by-step explanation:

From the question we are told that

The population mean for trout is $\mu_1 = 12 \ in$

The standard deviation is $\sigma_1 = 2.75 \ in$

The population mean for base is $\mu _2 = 4 \ lb$

The standard deviation is $\sigma_2 = 0.8 \ lb$

The number of trout caught $x_1 = 18$

The number of bass caught $x_2 = 6$

Generally z-value(standardized value ) for the of number trout caught is mathematically represented as

$z_1 = \frac{x_1 - \mu_1}{\sigma_1 }$

substituting value

$z_1 = \frac{18 - 12}{2.75 }$

$z_1 = 2.18$

Generally z-value(standardized value ) for the of number bass caught is mathematically represented as

$z_2 = \frac{x_2 - \mu_2}{\sigma_2 }$

substituting value

$z_2 = \frac{6 - 4}{0.8 }$

$z_2 = 2.5$

From our calculation we see that $z_2 > z_1$

The fish that was the better catch is the bass fish

Describe the process you used to write the equation of a line through two points.

xenn [34]

You can use point slope formula.
$y- y_{1}=m(x- x_{1})$
By getting the slope (m) from ∆y/∆x
You can plug it into the equation and plug in either of the two points as x1 and y1. This will result in the value for b. Plug that into the final equation and you have your answer!
