I'm assuming that x 8 = x⁸ and 3x 5 = 3x⁵.
So let's solve.
x⁸ + 3x⁵ = x⁵(____)
x⁸ + 3x⁵ = x⁵(x³ __)
x⁸ + 3x⁵ = x⁵(x³ + 3)
Therefore the missing expression is (x³ + 3)

The similarities are VWX ~ YVX ~ YWV. Matching corresponding letters, you have
WX/WV = VX/VY = WV/WY
The appropriate choice is ...
B. VX/VY = WV/WY
Answer:
<u>The standard error of distribution for n = 4 is 5 and for n = 25 is 2.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Population mean = 72
Standard deviation = 10
Sample₁ = 4
Sample₂ = 25
2. For finding the standard error of the mean, we use the following formula:
Standard error = Standard deviation / √Size of the sample
Standard error for Sample₁ = 10/√4
<u>Standard error for Sample₁ = 10/2 = 5</u>
Now, let's find the standard error for Sample₂
Standard error for Sample₂ = 10/√25
<u>Standard error for Sample₂ = 10/5 = 2</u>
Answer:
I'm assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes
18+0.06m≥88.56
we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.
0.06m≥70.56
Then we dives by 0.06
m≥1176
Rania has used at least 1176 minutes
