Sample space ={5G, 2Y, 8R, 3P} =18 POSSIBLE OUTCOME

1st draw: P(R) = 8/18 = 4/9 = 0.444
2nd draw (no replacement, means already one Red is picked up, so the sample space has been reduced): P(another one more RED) = 7/17 =0.411

PLEASE HELP! We can translate ()=2|−2|−5 to the right 3 units and up 5 units to create (). Write the equation for function g.
alisha [4.7K]

Answer:

g(x)=2\,|x-5|

Step-by-step explanation:

Recall that a horizontal translation (shift) in 3 units to the right involves directly subtracting 3 from the variable x (horizontal axis variable) , and that moving the function up 5 units involves adding to the whole function 5 units. That is:

g(x)=2\,|x-3-2|- 5+ 5\\g(x)=2\,|x-5|+0\\g(x)=2\,|x-5|

One condition for performing a hypothesis test is that the observations are independent. Marta is going to take a sample from a
AleksandrR [38]

Answer:

The correct answer to the following question will be "60 students".

Step-by-step explanation:

Marta will be taking a sampling frame from some kind of 600 student group.

Mean,

N = 60  

Although the sampling method could perhaps consist of the following components 10% of the population,

⇒  600\times 10 \ percent

⇒  60

In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.

Complete the sequence.<br><br>37.25​, 35.5​, 33.75​, __, __.
Leviafan [203]

Answer:

37.25​, 35.5​, 33.75​, <u>32</u>, <u>30.25</u>.

Step-by-step explanation:

Subtract the first term from the second term:

35.5 - 37.25 = -1.75

Subtract the second term from the third term:

35.5 - 33.75 = -1.75

The common difference is -1.75.

To find each subsequent term, add the common difference to the current term.

33.75 + (-1.75) = 32

32 + (-1.75) = 30.25

Answer:

37.25​, 35.5​, 33.75​, <u>32</u>, <u>30.25</u>.
