5^9/5^5= 625
You can either change the exponents to their equivalent whole numbers or subtract exponents.
The answer could also be represented as 5^4
The.value of x woukd be 2
Answer:
7:10:34
Step-by-step explanation:
1. Ratio outline:
Length 1:Length 2:Perimeter
2. Length 1 = 35 feet
3. Length 2 = 50 feet
4. Perimeter = Length of all sides
- Since, a ractangle has 4 sides and the opposite sides are equal, we do Perimeter = 35+50+35+50 = 170
5. Substitute the values into the ratio outline:
35:50:170
6. Convert into simplest form: Divide by greatest common factor (5)
7:10:34
Answer:
Step-by-step explanation:
Given that a delivery driver has an average daily gasoline expense of $55.00. The standard deviation is $10.00.
As per central limit theorem, for samples of large size drawn at random, the sample mean follows a normal distribution irrespective of the original distribution.
Hence here we can say sample mean
= N(55,1.361)
required probability =
the probability the mean of his sample will be between $45.00 and $65.00
=
i.e. almost a certain event.
