The number 4 is written on my whiteboard. Every time it rains, I multiply the number on the whiteboard by 2/3, erase the origina

l number, and write the new number on the whiteboard. When it snows, I multiply the number on the whiteboard by 3/5, and I replace the original number with the new number. It has rained 5 times and snowed 4 times this month. At the end of the month, what number is on the whiteboard?

Use what you know about translations of functions to analyze the graph of the function f(x) = (0.5)x−5 + 8. You may wish to grap
IrinaVladis [17]

Answer:

The Translation is 5 units to the right and 8 units up

Step-by-step explanation:

* Lets talk about some transformation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Now lets solve the problem

∵ The parent function is y = (0.5)^x

∵ f(x) = (0.5)^x - 5 + 8 after translation

- The x in the first function is (x - 5) in the second function

∴ There is a horizontal translation to the right 5 units

- the first function is (0.5)^x in the second function y = (0.5)^x - 5 + 8

∴ There is a vertical translation up 8 units

* The Translation is 5 units to the right and 8 units up

- Look to the attached graph to more understand

- The purple graph is y = (0.5)^x

- The black graph is f(x) = (0.5)^x-5 + 8

- To check the answer take a point from the y = (0.5)^x as (0 , 1), the

 image of this point on f(x) is (5 , 9)

-The point (0 , 1) is shifted 5 units to the right and 8 units up

∴ Its x- coordinate move from 0 to 5, y- coordinate move from 1 to 9

-4(3/2x - 1/2) = -15
adelina 88 [10]

Answer:

2.8333333333333333333

Step-by-step explanation:

I have high iq

-4(3/2x - 1/2) = -15

Distribute -4

-6x + 2 = -15

Subtract 2 from both sides

-6x = -17

Divide 6 from both sides

x = 2.83333333333333333

fermium-253 has a half-life of three days. a sample contains 400 g. how long will it take for the sample to decay to 100 g?
sladkih [1.3K]
This is a relatively easy half life calculation.
After one half-life period, half of the isotope remains.
After two half-life periods, one quarter of the isotope remains.
That being the case, we see this will take 2 half-life periods or 6 days.

Upper A baseball organization tests players to see whether they are using​ performance-enhancing drugs. Officials select a team
aleksklad [387]

Answer:

Cluster sampling

No

Step-by-step explanation:

Missing part of Question

Find:

a) Which type of sample is this?

b) Is it the correct choice ?

Solution:

- Simple random sample is the one in which every individual would have equal chance of being selected.

- Stratified random sample draws simple random sample from the independent sub-groups.

- Systematic sampling is letting every kth individual be in the sample ( k as an integer )

- Convenience sampling is used for example voluntary response or a sub-group from the population.

a)

Cluster sampling was used in our case because one of all the teams were chosen and this entire team is in this sample.

b)

No. This method has limitation of giving us a shortsighted view which lacks the overview on the use of performance-enhancing drugs, we can only use this sample to draw conclusions on the team.
