Answer:

s + g = 575

g = 75 + s

g = 325

s = 250

Step-by-step explanation:

Given that :

Total amount earned by Sharon and Geordi = $525

Also, Geordi earned $75 more than Sharon

Let amount earned by Sharon = s

Amount earned by Geordi = g

Equations :

s + g = 575 - - - equation 1

g = 75 + s - - - equation 2

Put g = 75 + s in equation 1

s + 75 + s = 575

2s + 75 = 575

2s = 575 - 75

2s = 500

s = 250

g = 75 + s

g = 75 + 250

g = 325

Using the logarithm, solve the following equation for x.<br> 6400 = (8) (2^4x)

expeople1 [14]

Answer:

x = 2.411

Step-by-step explanation:

6400 = (8) (2^(4x))

Divide both sides by 8 to get;

6400/8 = (2^(4x))

800 = (2^(4x))

Using logarithms, we can solve as;

Log 800 = 4xLog 2

4x = Log800/Log2

4x = 2.9031/0.3010

4x = 9.6449

x = 9.6449/4

x ≈ 2.411

Need help!!! Thanks!!!<br> Pre-Cal<br> 27^(2x) = (1/9)^(x-1)

DiKsa [7]

Answer:

$x = \frac{1}{4}\\$

Step-by-step explanation:

Given:

$27^{2x} = (\frac{1}{9})^{x-1}\\$

Rewriting your equation:

$(\frac{1}{27})^{-2x} = (\frac{1}{9})^{x-1} \\ ((\frac{1}{3})^3)^{-2x} = ((\frac{1}{3})^2)^{x-1} \\ (\frac{1}{3})^{-6x} = (\frac{1}{3})^{2(x-1)}$

Disregard same bases:

$-6x = 2(x -1)$

Solve for $x$ :

$-6x = 2x -2 \\ -8x = -2 \\ x = \frac{1}{4}$

If a standard dice ius rolled 50 times what s the theretical probibility of rolling a 4

saul85 [17]

We seems to be being asked the probability of rolling at least one four in fifty tries, which should be pretty high. As usual with "at least" questions, we write

p = P(at least one 4) = 1 - P(no fours at all)

The probability of a four on one roll is of course 1/6, so the probability for "not a four" is 1-1/6=5/6. We want the probability of a conjunction of 50 independent events: no four on the first roll and no four on the second roll and...

For a conjunction of independent events we multiply their probabilities. That's 5/6 times itself 50 times. So our answer is

$p = 1 - \left( \frac 5 6 \right)^{50}$

If we need a decimal approximation, it's

$p \approx 0.999890 = 99.9890\%$
