Answer:

\log _3\left(\frac{x^{\frac{1}{2}}}{\left(y+8\right)^2}\right)

Step-by-step explanation:

-> Apply log rules

\log _3\left(x^{\frac{1}{2}}\right)-2\log _3\left(y+8\right)

->

\log _3\left(x^{\frac{1}{2}}\right)-\log _3\left(\left(y+8\right)^2\right)

-> Apply basic math rules

\log _3\left(\frac{x^{\frac{1}{2}}}{\left(y+8\right)^2}\right)

Please help me with my Algebra homework!!!

Answer:

B) No Unique Solutions

Step-by-step explanation:

Given:

z=x+5y-14

-2y=-4\\y={-4}{-2}=2

3x+y-3z=14

now we now the value of y = 2 so we will substitute in equation  z=x+5y-14

z=x+5\times2-14\\z=x+10-14\\z= x-4

Now, We have value of y=2 and value of z=x-4 Substituting in both the value in equation 3x+y-3z=14

3x+2-3(x-4)=14\\3x+2-3x+12=14\\14=14

which means that the equation has Infinite solutions.

A particular battery claims to have a mean life of 400 hours with a standard deviation of 30 hours. Approximately what percent o
Svetach [21]

Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, we have that the mean and the standard deviation are given, respectively, by:

\mu = 400, \sigma = 30.

The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{420 - 400}{30}

Z = 0.67

Z = 0.67 has a p-value of 0.7486.

1 - 0.7486 = 0.2514.

0.2514 = 25.14% of the batteries will last more than 420 hours.
