Step 1 :
Equation at the end of step 1 :
(22xz3 • x4) • z5
Step 2 :
Multiplying exponential expressions :
2.1 z3 multiplied by z5 = z(3 + 5) = z8
Final result :
22x5z8
Final answer:
The given expression xz^3*4x^4z^5 can be simplified by adding the exponents of same variables when they are multiplied resulting in the simplified expression 4x^5z^8.
Explanation:
Yes, it's possible to simplify the expression xz^3*4x^4z^5. The rule here involves combining the same variables and adding their exponent parts. First, let's look at x terms. You have x in both terms, one is x^1 (since an x without any shown exponent has 1 as exponent) and another is x^4, so when you multiply them (x^1 * x^4), you add their exponents to get x^5. Similarly for the z term: you have z raised to the power of 3 in the first term and z raised to the power of 5 in the next. When you multiply them (z^3 * z^5), you add their exponents to get z^8. The constant 4 is also being multiplied here and is retained in the final answer. In conclusion, the simplified expression will be 4x^5z^8.

I don’t understand how to solve it
c = 4w + 3
B. c = w + 9
c = w − 3
C. w = c + 9
w = c − 3
D. w = c − 9
w = 4c + 3
Answers
The answer will be option B that is [ c = w + 9 ] and [ c = w − 3 ].
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
- Variable c is 9 more than variable w.
- Variable c is also 3 less than variable w.
From the given data in the question, the expression will be given as:-
[ c = w + 9 ]
[ c = w − 3 ]
Therefore the answer will be option B that is [ c = w + 9 ] and [ c = w − 3 ].

statistical analyses. The researcher administers a survey to 15 students who

Answers
Answer:
B. Select a random sample of students who go to the work laboratory
Step-by-step explanation:
The best way to get acurate results is by selecting a random sample of students. If the students administers a survey to the students that are seated at the front of the laboratory he could get biased results.
The students that are seated in fron of the laboratory could obey to a certain characteristic (ie. They could be very applied students), which could definitely provide us with a different result.
The survey is just fine. We don't need any instrument to test statistical analysis understanding. Also, using a larger sample size of students seated in front of the laboratory won't make much difference. Finally, Administering instruments to a group who does not go to the work laboratory makes no sense. You can not measure effectiveness on people that don't assist to class.
