I need geometry help

fiasKO [112]

I believe you can do x + 2.7 = 16.

I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.

Your answer is 16 - 2.7
(13.3)

A binomial experiment has 4 trials in which p = 0.4. What is the probability of 3 successes?

Kaylis [27]

The probability of 3 successes is 0.0384

<h3>How to determine the probability?</h3>

The given parameters are:

Trials, n = 4
Probability of success, p = 0.4

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1 - p)^{n-x$

So, the probability of three successes is:

$P(3) = ^4C_3 * 0.4^3 * (1 - 0.4)^{4 -3$

Evaluate the factors in the expression

$P(3) = ^4C_3 * 0.0384$

Evaluate the combination expression

P(3) = 1 * 0.0384

Evaluate the product

P(3) = 0.0384

Hence, the probability of 3 successes is 0.0384

jerome tries to find the value of the expression 3-6+5 by first applying the communtative property. he rewrites the expression a

slega [8]

The commutative property is a property of <em>addition</em>, not of <em>subtraction</em>. It can work in a subtraction problem if you keep the sign with the number, so you're adding positive and negative numbers.

3 - 6 + 5

= (3) + (-6) + (5)

= (3) + (5) + (-6)

= 3 + 5 - 6
