Hello from MrBillDoesMath!
Answer:
The average is increased by 5
Discussion:
Let x be one number and y the other number.
Average of x,y = (1/2) ( x + y)
if, say, x is increased by 10 then the average of the numbers is
( ( x+ 10) + y) /2
= (x+y)/2 + 10/2 => (x+y)/2 is the average of the original numbers
= (x+y)/2 + 5
So the average is increased by 5
Thank you,
MrB
To solve this, you divide the price by the amount of ounces, and find the one which results in the smallest number. That was B, $4.29 for 12 ounces.
Answer:
0.1905 = 19.05%
Step-by-step explanation:
We have a total of 106 containers of oxygen, from which:
20 have oxygen not ionized, 86 have oxygen ionized.
If the first one selected is ionized, now we have 20 not ionized and 85 ionized.
So the probability of the second one selected being not ionized is the number of not ionized (20) over the total number of containers (20 + 85):
P = 20 / (20 + 85) = 0.1905 = 19.05%
Answer:
Option C is correct.
Step-by-step explanation:
An exponential function is of the form:
....[1] where a is the initial value, x is any real number and b is the growth factor
Also, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).
Then, the growth "rate" (r) is determined as b = 1 + r.
and the decay "rate" (r) is determined as b = 1 - r
- If b> 1, then it is exponential growth function.
- if 0<b< 1. then it is exponential decay function.
Also, b = 1+ 4
Given the equation: 
On comparing given equation with [1] we get;
a = 50 and b = 1.15
Since, b = 1.15 > 1
Therefore, the given equation represents the exponential growth.
(A)
Yes, this
equation represents the exponential growth.
(B)
Initial value (a) = 50
(C)
Here growth factor, b = 1.15
and
1+ r = 1.15.
⇒
1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20
