Log(7)+log(x-4)=1
log(7(x-4))=1 by the law of logarithms

ASSUMING log is to the base 10,
then by the law of logarithms, [10^log(x)=x]
7(x-4)=10^1=10
solving for x
x=(10/7)+4=38/7

Which expression is equivalent to log3 c/9?
stepladder [879]
Hello!

There is an existing logarithmic property that states that log \frac{M}{N} is equal to log M-logN.

Following that property, we can tell that log \frac{c}{9} would be equal to log(c)-log(9).

ANSWER: log(c)-log(9) (third option)

The resistance for resistors of a certain type is a random variable Xhaving the normal distribution with mean 9 ohms and standar
Y_Kistochka [10]

Answer:

P(8.6

And using the normal standard distirbution or excel we got:

P(-1

Step-by-step explanation:

Let X the random variable that represent the resistance for resistors of a population, and for this case we know the distribution for X is given by:

X \sim N(9,0.4)  

Where \mu=9 and \sigma=0.4

We are interested on this probability

P(8.6

And the z score formula is given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(8.6

And using the normal standard distirbution or excel we got:

P(-1

Jack and Nina are graphing two equations on a coordinate grid. Jack has graphed the equation y = 2x.
Pepsi [2]

ANSWER

A) For all x > 0 the graph will be higher.

EXPLANATION

Jack's graph has equation

y=2x

This graph passes through the origin and has slope 2.

Nina's graph is y=5x.

This graph also passes through the origin and has slope 5.

Since 5 is greater than 2, for all x>0, Nina's graph will be higher.
