First off, the "write" youre trying to spell should be "right". Also, Im not sure if this is a true or false, or if Im solving for "m", so I will do my best.

The first step would be to distribute the 3 to 2.4 and -1.1m, by doing 3 times 2.4 giving you 7.2 and then doing 3 times -1.1m giving you -3.3m.

Your new equation is now 7.2 - 3.3m = 2.7m + 3.2 (This is false if this is a true or false problem)

To solve for "m" you would need to add 3.3m to 2.7m to elimate it from the side of 7.2. Your new equation is now 7.2 = 6.0m + 3.2. You now want to subtract 3.2 from the side of 6m to elimate it and also subtract from the side of 7.2, now giving you 4.0 = 6.0m

To get "m" you need to divide 6 from both sides giving you your final answer of, m = .69

$e ^{2x} = ln5$

Solve for the real domain

$e ^{2x} = ln(5)$

if $f(x) =g(x),$ then $ln(f(x))= ln(g(x))$

$ln(e ^{2x} ) = ln(ln(5))$

Solve : <span> $ln(e ^{2x} ) = ln(ln(5))$
</span>
use the logarithmic definition :

$ln(e^{f(x)} ) = f(x)$

$ln(e^{2x} ) = 2x$

$2x=ln(ln(5))$

Divide both sides by 2 :

$\frac{2x}{2} = \frac{ln(ln(5))}{2}$

$x= \frac{ln(ln(5))}{2}$

hope this helps!

In a carnival game, there are six identical boxes, one of which contains a prize. A contestant wins the prize by selecting the b

myrzilka [38]

Answer:

D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.

Step-by-step explanation:

The Number of boxes = 6

Box containing a prize = 1

Probability of success, p = box containing a price / number of boxes = 1 /6

Number of trials = 5

Probability of success on exactly 2 trials, r = 2

Hence,

P(r = 2) = nCr * p^r * (1-p)^(n-r)

n = 5 ; r = 2 ; p = 1/6

Using a binomial probability calculator :

P(r = 2) = 0.1608

Deacon had 12 1/3 ounces of juice, but he drank 3 2/3 ounces. How much juice is left?

alexandr1967 [171]

You need to know:

$a \frac{b}{c} = a + \frac{b}{c} = \frac{(a*c) + b}{c}$

Be careful though:

$a \frac{b}{c} ≠ a(\frac{b}{c})$

Using this principle, we can say:
12 1/3 = 37/3
3 2/3 = 11/3
Quantity of juice left = Initial quantity - Quantity drunk
So:
Quantity of juice left = 37/3 - 11/3 = 26/3

There will be 26/3 ounces of juice remaining after 3 2/3 are drunk from the total of 12 1/3 ounces that Deacon had initially.

What is the sum of all even numbers between 1 and 1000

weeeeeb [17]

There are 500 even numbers from 1 to 1000 starting with 2 and ending with 998. The sequence of even numbers is an arithmetic sequence with a common difference of 2. Using the equation for the arithmetic series,

S = (a1 + an)(n/2)
and substituting,

S = (2 + 998)(500/2)
we get,

S = 250,000

Therefore, the sum of all even numbers between 1 and 1000 is 250,000.
