Suppose a basketball player has made 222 out of 428 free throws. If the player makes the next 2 free throws, I will pay you $12.

Otherwise you pay me $6. Step 2 of 2 : If you played this game 543 times how much would you expect to win or lose? Round your answer to two decimal places. Losses must be expressed as negative values.

Prove the polynomial identity.

aleksandr82 [10.1K]

Explanation:

Since we have given that

$(2x+1)^2-2(2x+1)$

Now, we have to prove it as

$(2x+1)(2x-1)$

Now, start the iterations:

$(2x+1)^2-2(2x+1)\\\\=4x^2+1+4x-4x-2\\\\=4x^2+1-2\\\\=4x^2-1\\\\=(2x)^2-1\\\\=(2x+1)(2x-1)$

So, first blank will be filled with

$4x^2+4x+1$

Second blank will be filled with

$4x^2-1$

Hence proved.

When simplified, what is the exponential<br>form of the following expression 3⁴.35.36

matrenka [14]

Answer:

$3^4*3^5*3^6 = 3^{15}$

Step-by-step explanation:

Given

$3^4*3^5*3^6$

Required

Simplify

To do this, we apply laws of indices:

$a^m * a^n = a^{m+n}$

So:

$3^4*3^5*3^6 = 3^{4+5+6}$

Add the exponents

$3^4*3^5*3^6 = 3^{15}$

What is the mean and median of the lengths . <br> 10,31,36,36,38,42,47,48,49,and 52

Olin [163]

Answer:

$Mean = 38.9$ $Median = 40$

Step-by-step explanation:

When you find mean, you must add all the numbers together then divide by the amount of numbers.

$10+31+36+36+38+42+47+48+49 + 52$

$==> 389$

There are 10 numbers.

$389 / 10$

$==> 38.9$

To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.

$(x + y ) / 2$

$38 + 42$

$==> 80$

Divide by 2

$80 / 2$

$==> 40$
