<h3>(-3j²k³)²(2j²k)³</h3>
(-3j²k³)²(2j²k)³ = <em>When a power is raised to a power the exponents have to be multiplied.</em>
= (-3²j⁽²*²⁾k⁽³*²⁾)(2³j⁽²*³⁾k³) = <em>We can take out the constants</em>
= (9)(8)(j⁴k⁶)(j⁶k³) = <em>We can group the same variables</em>
= 72(j⁴j⁶)(k⁶k³) = <em>When multiplying two powers that have the same base, you have to add the exponents.</em>
= 72 j⁽⁴⁺⁶⁾k⁽⁶⁺³⁾ = 72j¹⁰k⁹
Answer = 72j¹⁰k⁹
Hope this helps!
Answer:
a. 0.0783
Step-by-step explanation:
We have these following probabilities:
A 15% probability that a flight is delayed
An 85% probability that a flight is on time
Which of the following is closest to the probability that it will take 5 selections to find one flight that is delayed?
We want the first four flights to be on time. Each flight has an 85% probability of being on time.We want the fifth flight to be late.
Each flight has a 15% probability of being late.
So
0.85*0.85*0.85*0.85*0.15 = 0.0783
So the correct answer is:
a. 0.0783
Answer:
The answer is B
Step-by-step explanation:
A farm is in the shape of a rectangle, 1/8 of a mile long and 2/5 of a mile wide. What is the area of the farm?
When looking for area, you will always multiply or divide.
The multiplication in this problem is 2/5 x 1/8, which is the same as the Multiplication Operation given.
So, the answer is B.
9(x + 3) + 15x
9x + 27 + 15x ...combine like terms
24x + 27 <==
Answer:
5750
Step-by-step explanation:
×5000=250
