5 0

Answer:

Numbers greater than 4 are 5 and 6

So we have 2 numbers out of 6 numbers so the probability is equal to 2/6 = 1/3

And 1/3 of 12 is equal to 4

So Brian expect to roll a number greater than 4,

Four times.

Ludmilka [50]

Answer:

D. He forgot to subtract the area of the base from the total surface area of the  cube.

What is the sum of the first 6 terms of this geometric sequence? –4, –16, –64, –256, …
MatroZZZ [7]

a_1=-4;\ a_2=-16;\ a_3=-64;\ a_4=-256;\ ...\\\\r=\dfrac{a_{n+1}}{a_n}\to r=\dfrac{a_2}{a_1}\to r=\dfrac{-16}{-4}=4

The formula of the sum of a geometric sequence:

S_n=a_1\cdot\dfrac{1-r^n}{1-r}

We have:

a_1=-4;\ n=6;\ r=4

substitute:

S_6=-4\cdot\dfrac{1-4^6}{1-4}=-4\cdot\dfrac{1-4096}{-3}=-4\cdot\dfrac{-4095}{-3}=-4\cdot1365=-5460

Answer: C. -5460

ax - b = 3x + 5d

For x;

ax = 3x + 5d +b

x = (3x + 5d + b)/a

Now for d;

ax - b -3x = 5d

d= (ax - b - 3x)/5
