Answer:
40n
Step-by-step explanation:
(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.
(n-40): This one is using subtraction, so this one is an obvious no.
(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.
(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.
Answer:
20
Step-by-step explanation:
A data is given and the mean of data is 19.6 .The data is ,
12 , 16 , 22 , x , 28 .
We know that the mean is sum of observations divided by Total number of observations . So that ,
⇒ 12 + 16 + 22 + x + 28/ 5 = 19.6
⇒ 78+x/5 = 19.6
⇒ 19.6 × 5 = 78 + x
⇒ 78 + x = 98
⇒ x = 98 - 78
⇒ x = 20
<h3>
<u>Hence </u><u>the</u><u> value</u><u> of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u><u>.</u></h3>
[Step 1] Put data in order least to greatest
-> Data is already in order, fantastic!
[Step 2] Find the medium of all the data
-> We will find the middle value
-> See attached, in black
-> The value is 7.5
[Step 3] Find the medium of our halves
-> We will find the middle value of each of the halves
-> See attached, in white
-> For this, the value of the first quartile it is 3.5
-> For the, the value of the third quartile it is 9
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Answer:
all possible y values
Step-by-step explanation:
any y value that goes in the function is in the range , an easier way to determine that would be using graphs.
The circumference of a circle is <span>πd
You know the circumference of the rim of the wheel is 48 inches so to find the diameter (d) you divide 48/3.14 which gives you 15.29 inches.
As the spoke goes from the center to its rim, it it is the radius, which is half of the diameter.
15.29/2 is B) 7.64 inches.</span>
