Write as a single logarithm.<br> ln(5) + 3/5 ln(32) − ln(4)
In-s [12.5K]

Answer:

ln(10)

Step-by-step explanation:

Let's rewrite the expression as a single logarithm using the next propierties:

log(x*y)=log(x)+log(y)\\y*log(x)=log(x^{y} )\\log(\frac{x}{y} )=log(x)-log(y)

So:

ln(5)+ln(32^{\frac{3}{5} } )-ln(4)

Where:

32^{\frac{3}{5} }=\sqrt[5]{32^{3} } =\sqrt[5]{32768} =8

Therefore:

ln(5)+ln(8)-ln(4)=ln(5*8)-ln(4)=ln(\frac{8*5}{4})=ln(\frac{40}{4})=ln(10)

Find the probability that a Type A bulb lasts at least 300 hours and a Type B bulb lasts at least 400 hours.
barxatty [35]

Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

Step-by-step explanation:

We require more information by I will explain in principle:

If Type A has at least 300 hours and Type B at least 400 hours.

(X>3)(Y>4)=P(X>3)P(X>4)

You need to determine the Probability density function of X and Y and then subtract 1 from both

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions.
joja [24]

Answer:

<h3>B. It has infinite solutions</h3>

Step-by-step explanation:

Given the system of equations:

2t + w = 10 ..... 1

4t = 20 − 2w ... 2

From 1:

w = 10-2t ...3

Substitute 3 into 2 to have;

4t = 20 - 2(10-2t)

4t = 20-20+4t

4t = 4t

Let t = k

Substitute t = k into 1 and get w;

From 1: 2t + w = 10

2k + w =10

w = 10 - 2k

<em>k can take any integers. This shows that the solution to the equation is infinite</em>
