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

12x² - 11x+2<br> How do I factor this?
Mars2501 [29]

Answer:

(3x-2)(4x-1)

Step-by-step explanation:

1. take the a and the c value and multiply them together to isolate x^2. it should be x^2 -11 +24.

2. find what multiplies to 24 and adds up to -11. its -8 and -3.

3. factor like normal and get (x-8) (x-3)

4. divide the -8 and -3 in the factors by 12 (the original a value)

-8/12 = -2/3 and -3/12 = -1/4.

5. the denominator gets moved to the x value to get (3x-2)(4x-1)

Quick algebra 1 question for 10 points!
Anna35 [415]

<u>Answer:</u>

h(-2) =\boxed{ \bf -111}

<u>Step-by-step explanation:</u>

The function h(x) is defined as:

h(x) = 12x^3 - 15

To calculate the value of h(-2), we have to replace the x in the definition of h(x) with -2:

h(-2) = 12(-2)^3 - 15

       ⇒ 12(-8) -15

       ⇒ -96 - 15

       ⇒ -111
