What is the value of a when we rewrite 15^x as a^x/6

jarptica [38.1K]

Answer:

a = 11,390,625.

Step-by-step explanation:

a^x/6 = (a^1/6)^x

(a^1/6)^x = 15^x so:

a^1/6 = 15

1/6 ln a = ln 15

ln a = 6 ln 15

ln a = 16.2483

a = 11390625.

How do you multiply -5 that has an exponent of 4 but no parenthesis with 4? Please explain

muminat

A negative sign in front of any expression, is in effect a factor of -1, so -7 for example is really the same as saying -1 * 7, because the -1 is multiplying it right in front of it, therefore

$\bf -5^4\implies -1\cdot 5^4\implies -1\cdot 625\implies -625
\\\\\\
\textit{as opposed to }(-5)^4\implies (-1\cdot 5)^4\implies (-1)^4\cdot 5^4
\\\\\\
(-1\cdot -1\cdot -1\cdot -1)(5\cdot 5\cdot 5\cdot 5)\implies 1\cdot 625\implies 625$

ohaa [14]

Answer:

C. the life of Supplier B's tires is more predictable than the life of Supplier A's tires.

Step-by-step explanation:

A: The distributions have the same mean, but different standard deviation. They are not the same distribution.

B: The distributions have the same mean, which means on average the tire lifetimes are the same from both suppliers.

C: A smaller standard deviation means values tend to be closer to the mean, hence more predictable. Supplier B's tires have a more predictable life.

D: "Dispersion" is another way to describe the measure provided by standard deviation. Supplier B's tires have a lower tire life dispersion.
