Answer:

2x - 2

Step-by-step explanation:

There are two steps to take here. First add together the -3 + 2 in the brackets:

2(x - 3 + 2)

= 2(x - 1)

Now use the distributive property and multiply each term in the brackets by two:

2(x - 1)

= 2x - 2

And you now have it in simplest form.

The answer is 1.25.

The equation for slope is rise over run. Y is the rise and X is the run. The point equation is (y2-y1)/(x2-x-1) = slope.

Plugging in the numbers: (-4-1)/(-4-0) = 1.25

Holly deposited $10,000 in an investment account. After 6 years the account is worth approximately $13,400. Which formula repres

Nady [450]

Formula for exponential growth is:

A = P(1+r)^t

Where A is the resulting amount, P is the initial value, r is the rate, and t is the time passed.

Filling this out for this situation gets you:

13400 = 10000(1+r)^6

Solving for r:

Divide 13400 by 10000

1.34 = (1+r)^6

Take the 6th root of both sides...
1 + r = 1.05

No more work is needed, since you aren’t solving for r.

Full equation:
V = 10000(1.05)^t
Answer C is correct

Answer: This result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong

Step-by-step explanation:

Since we have given that

n = 100

p = 0.16

q = 1 - 0.16 = 0.84

So, Mean would be

$np=100\times 0.16=16$

and standard deviation would be

$\sqrt{np(1-p)}=\sqrt{100\times 0.16\times 0.84}=3.67$

Now, if there are 19 green,

so, we will check how it is far,

$\dfrac{19-16}{3.67}=\dfrac{3}{3.67}=0.817$

Since it is 0.817 standard deviations away from the mean.

So, this result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong.
