A bag contains 6 red marbles and 30 white marbles. If a representative sample contains 3 red marbles, then how many white marbles would you expect it to contain?

Answers

Answer 1

Answer: there are 36 marbles total.
if the sample contains 3 red marbles, then that is half of the total amount of 6. therefore, half of each color is being taken for the sample. this means that you should expect for there to be 15 while marbles in the sample.

4.79+ what=37 100-what=52.7

Answers

4.79 + x = 37
-4.79 -4.79 4.79 + 32.21=37
x=32.21

100 - x =52.7
-100 -100 100- 47.3=52.7
-x= -47.3
-x -x
x= 47.3

Question 1)

solve your equation step-by-step.

4.79+x=37100

Simplify both sides of the equation.

x+4.79=37100

Subtract 4.79 from both sides.

x+4.79−4.79=37100−4.79

x=37095.21

Question 2)

solve your equation step-by-step.

100−x=52.7

Simplify both sides of the equation

100−x=52.7

100+−x=52.7

−x+100=52.7

Subtract 100 from both sides.

−x+100−100=52.7−100

−x=−47.3

Divide both sides by -1.

−x−1=−47.3−1

x=47.3

Answers

Answer:

22x5z8

Step-by-step explanation:

xz3*4x4z5

Final result :

22x5z8

Step by step solution :

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.
