Geometric sequence

an=a1(r)^(n-1)
so

given
a1=4
and a3=36

36=a3=4(r)^(3-1)
36=4(r)^2
9=r^2
3=r


an=4(3)^(n-1)
a6 is
a6=4(3)^(6-1)
a6=4(3)^5
a6=4(243)
a6=972

a6=972

A 6-sided die with sides numbered 1 through 6 is tossed. A penny is then tossed. If the penny comes up heads, the value of the d
Montano1993 [528]

Answer:

The probability that the outcome is less than 6 is 58.333%.

Step-by-step explanation:

Since a 6-sided die with sides numbered 1 through 6 is tossed, ya penny is then tossed, and if the penny comes up heads, the value of the die is multiplied by 2, but otherwise, the value of the die is left unchanged, to determine what is the probability that the outcome is less than 6 the following calculation must be performed:

(5/6 + 2/6) / 2 = X

(0.8333 + 0.0333) / 2 = X

1.1666666 / 2 = X

0.583333 = X

Therefore, the probability that the outcome is less than 6 is 58.333%.

Sergeeva-Olga [200]

Explanation:

At each step, the product of the quotient digit and the divisor is subtracted from the dividend. This gives you the new dividend.

When the quotient digit is 7, the product of 7 and 5 is subtracted from the dividend. The dividend at that point is 35, so you have 35 - 35 = 0. The 0 is the next dividend. Among other things, that tells you you're done. (Any additional quotient digits will be zero.)
