Answer:

x=\frac{1}{4}

Step-by-step explanation:

81^{x+1}+3^{4x}=246

81=3^4

Rewrite equation: 3^{4\left(x+1\right)}+3^{4x}=246

3^{4\left(x+1\right)}=3^{4x}\times 3^4

3^{4x}\times 3^4+3^{4x}=246

Factor out 3^{4x}:

3^{4x}\left(3^4+1\right)=246

Divide both sides by (3^4+1):

\frac{3^{4x}\left(3^4+1\right)}{3^4+1}=\frac{246}{3^4+1}

3^{4x}=\frac{246}{3^4+1}

3^{4x}=\frac{246}{82}

3^{4x}=3

Anything to the power of 1 is itself. Hence,

4x=1\\

x=\frac{1}{4}

2. What is the sample proportion of heads in your sample of 40? Report this value to your teacher.
Alexeev081 [22]

Answer:

\frac{18}{40}=0.45

Though it may vary, it's going closer to 0.5 as long as we enlarge our sample.

Step-by-step explanation:

1) Since a coin has heads and tails, then a sample proportion of 40 we can simulate it using some applets.

2) Here are the most common outcomes, as long as we continue on flipping coins.

\frac{18}{40}=0.45

If we continue enlarging our sample (80, 120,160...) the probability goes closer to 0.5

This shows: the theoretical probability goes closer and closer to the experimental probability of heads and tails

S_{80}=0.503\\S_{120}=0.50
