Mathematics

Answer:

(4, 4)

Step-by-step explanation:

This is the form of a hyperbola. Use this form to determine the values used to find vertices and asymptotes of the hyperbola.

\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1

Match the values in this hyperbola to those of the standard form. The variable h represents the x-offset from the origin, k represents the y-offset from origin, a.

a = 1

b = 3

k = 4

h = 4

Thus,

(x-4)^2 - \frac{(y-4)^2}{9} = 1

The center of a hyperbola follows the form of (h, k). Substitute in the values of h and k.

= (4, 4)

AfilCa [17]

Solution :

Sampling may be defined as the technique of selecting the individual members or the subset of the population to make a statistical inferences and estimates the characteristics of the entire population.

There are several sampling methods. This includes : Systematic sampling, clustered sampling, stratified sampling, quota sampling, judgement sampling, random sampling, convenience sampling and many more.

In the context, the sampling methods for each of the descriptions are :

a). The researcher use computer program to randomly choose a sample of 30 mice of the 1000 mice for using her study

   --- Simple Random

b). The researcher chose the 1st 30 mice as she can reach the door to the mouse room

   --- Convenience sampling

c). The mice those whose are kept in the cages on 10 various shelves in mouse room. The researcher or the experimenter chose the three mice from each shelve.

  ---- Stratified sampling

d). Each of the cage have 5 mice and the researcher randomly chooses 6 cages for her study

----- Cluster sampling

e). The researcher generates the list of the identification numbers which has been sorted from the smallest to the largest. The researcher randomly picks 1 mouse form the list and selects every 4 mouse until the researcher has 30 mice.

 ---- Systematic sampling

Anastaziya [24]
Easy.

7x + 2 = 2

7x = 2 - 2

7x = 0

x = 0 / 7

x = 0

Verify this by putting x = 0 ...

7 ( 0 ) + 2 = 2

0 + 2 = 2

2 = 2

Hence, "0" is the final answer.

Hope helps ........

-2+6x=12-x please help me solve this
Sidana [21]

Answer:

X=2

Step-by-step explanation:

-2+6x=12-x

add 2 to both sides

6x=14-x

now add 1x to both sides

7x=14

and finally divide both sides by 7 so you x is left alone

<h2>x=2</h2>
