Caden removed the label of a soup can like the one shown. What is the approximate area of the label if the can is 4 inches high

Dominik [7]

EXPLANATION

If the height of the can is 4 inches and the diameter is 3--> radius=1.5 inches, the area is given by the following relationhip:

$\text{Area}_{\text{label}}=2\pi rh$

Replacing terms:

$\text{Area}_{\text{label}}=2\pi\cdot1.5\cdot4=12\pi=37.7in^2$

The approximate area is 37.7 in^2

Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.

Lyrx [107]

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)

We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is

20/64 = .3125 which is 31.25%

7x-2=5x+14<br> X=?<br> (step by step needed)

prisoha [69]

Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

$7x-2-5x=5x+14-5x$
$2x-2=14$

Step 2: Add 2 to both sides.

$2x-2+2=14+2$
$2x=16$

Step 3: Divide both sides by 2.

$2x/2=16/2$
$x=8$

Step 4: Check if solution is correct.

$7(8)-2=5(8)+14$
$56-2=40+14$
$54=54$

Therefore, x = 8.
