What is bigger, 6 kilometers or 600 centimeters.

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 2) and (4, 0). Everything below and to t

yanalaym [24]

Answer:

Option C.

Step-by-step explanation:

A dashed straight line has a negative slope and goes through (0, 2) and (4, 0).

The given inequality is

$y$

We need find the point which is a solution to the given linear inequality.

Check the given inequality for point (2, 3).

$3$

This statement is false. Option 1 is incorrect.

Check the given inequality for point (2, 1).

$1$

This statement is false. Option 2 is incorrect.

Check the given inequality for point (3, -2).

$-2$

This statement is false. Option 3 is correct.

Check the given inequality for point (-1,3).

$3$

This statement is false. Option 4 is incorrect.

Therefore, the correct option is C.

Suppose a researcher is testing a new vaccine on mice to see how well it prevents the flu virus. The lab has 1000 mice available

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

A family went out to eat. Below is the number of coen dogs tbat each of the four people ate. Find the mean absolute deviation (m

Alexxandr [17]

Answer:

1.25

Step-by-step explanation:

Give the data:

X : 1 1/2 ___ 0 _____ 4 ______ 2 1/2

Mean absolute deviation (MAD) :

Σ|x - xbar| ÷ n

xbar = Σx/ n

Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8

xbar = 8/4 = 2

|x - xbar| :

|1 1/2 - 2|= 1/2

|0 - 2| = 2

|4 - 2| = 2

|2 1/2 - 2| = 1/2

Therefore,

MAD = (1/2 + 2 + 2 + 1/2) / n

MAD = 5/4

MAD = 1.25

Part A

Trava [24]

Answer:

The total water usage at the park this year, in gallons, U = 16,206 + 22.2·x

Step-by-step explanation:

The given parameters are;

The increase in water usage for both regular days and special event for the current year = 20%

The water usage for last year regular days = 13,505 gallons

The water usage per special event = 18.5 gallons

The total water usage = 13,616 gallons

Therefore, we have;

The water usage for regular days on the current year = 13,505 gallons + (20/100)×13,505 gallons = 16,206 gallons

The water usage per special event for the current year, x = 18.5 gallons + (20/100) × 18.5 gallons = 22.2 gallons

The total water usage, U, at the park this year in terms of 'x', the number of special events the park hosted is given by the sum of the amount of water used on regular days and the product of 'x', and the amount of water used per special event this year as follows;

U = 16,206 gallons + x × 22.2 gallons

∴ The total water usage at the park this year, U = 16,206 + 22.2·x
