Answer:

9b /a^5/2

Step-by-step explanation:

9√(a^-5 b^2)

9 sqrt( a^ -5 b^2)

Rewriting sqrt as ^1/2

9 ( a^ -5 b^2)^1/2

9 ( a^ -5) ^1/2 ( b^2)^1/2

we know that  an exponent to an exponent means multiply

9 a^ (-5*1/2)  b^(2*1/2)

9 a^-5/2 b^1

9b a^ -5/2

We know that x^-y = 1/x^y

9b /a^5/2

A random sample of 100 people was taken. Eighty of the people in the sample favored Candidate A. We are interested in determinin
stepan [7]

Answer:80 percent

Step-by-step explanation:

From the question, the total number of sample is 100 that is hundred(100) people . Eighty (80) people from the sample are in favour of candidate A.

Therefore, the mean statistic is one(1), that is, 0.8+0.05+1.15+2.00= 1.

So, total number from the hundred people supporting Candidate A divided by the total number of sample of the population multiply by a 100 percent;

= 80/100 × 100= 80%.

80% which is greater than 75%

Which of the following algebraic expressions is not simplified?
AlladinOne [14]

Answer:

Option D. a^2+6ab-2ba

Step-by-step explanation:

Option D because we have like terms: 6ab and -2ba=-2ab, then

a^2+6ab-2ba=a^2+6ab-2ab

Simplifying on the right side of the equation adding like terms:

a^2+6ab-2ba=a^2+4ab

What is 48,100,000,000,000 in scientific notation? 4.81×10−11 4.81×10−13 4.81×1011 4.81×1013
SSSSS [86.1K]
Given number is 4,8100,000,000,000. 

In this number of zero is 11. So we can write it as 481 * 10^{11}

But for scientific notation we will enter decimal after two place in reverse direction.For this we will also multiply number by 10^2.

So number will be 4.81 * 10^{11} *10^2 = 4.81 * 10^{13}

So fourth option is correct.
