Answer:

$64222.22

Step-by-step explanation:

If we call the original value as x, we can write:

1445 = x * (0.15)²   (Note: We write 1 - 0.85 = 0.15 and not 0.85 because 0.85 is the decay factor)

1445 = 0.0225x

x ≈ 64222.22

Answer:

<h2>$ 2000</h2>

Step-by-step explanation:

Let the original value be $ X

Decay factor = 0.85

Time = 2 years

Reduced value = $ 1445

Now,

Reduced value = original value * (decay){}^{number \: of \: years}

Plug the values

1445  = x  \times  {(0.85)}^{2}

Evaluate the power

1445 = x \times 0.7225

x =  \frac{1445}{0.7225}

Calculate

x = 2000

Hope this helps...

Best regards!!

In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.

What is the slope and the Y intercept of -12x-4Y=10
denis-greek [22]
To find the slope and y-intercept, you need to get the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. 

-12x - 4y = 10
+12x          +12x

-4y = 12x + 10
/-4          /-4

y = -3x - 10/4

olga nikolaevna [1]

Answer:

The probability of selecting three Democrats and two Republicans is 0.349

Step-by-step explanation:

Given:

The Number of Democrats = 6

The Number of Republicans = 8

To Find:

Probability of selecting 2 Democrats and 4 Republicans. = ?

Solution:

we have to select a committee of 6 people

Now the probability of selecting 2 Democrats and 4 Republicans.

 =>\frac{\mathrm{P}(\text { Selecting two Democrats }) \cdot \mathrm{P}(\text { Selecting four Republicans })}{\mathrm{P}(\text { Selecting } 6 \text { member from total } 14)}

=>\frac{C(6,2) \cdot C(8,4)}{C(14,6)}

=>\frac{ 6 C_{2 } \cdot 8 C_{4}}{14 C_{6}}

=>\frac{15\cdot 70}{3003}

=>\frac{1050}{3003}

=>0.349
