Answer:

$2^5*5$

Step-by-step explanation:

Step 1: Prime Factorization

$160$ → $2 * 2 * 2 * 2 * 2 * 5$

$2 * 2 * 2 * 2 * 2 * 5$ → $2^5*5$

Answer: $2^5*5$

Sue took a test in both biology and math last week. The biology test had a mean of 70 and a standard deviation of 7 whereas the

Anna [14]

Answer:

c. the biology test

Step-by-step explanation:

To answer this problem we need to calculate the z-score of both tests, using the formula:

z = (x - μ) / σ

Where x is Sue's score, μ is the mean, and σ is the standard deviation.

For the biology test, the z-score is:

z = (76 - 70) / 7 = 6/7 = 0.857

For the math test, the z-score is:

z = (76 - 75) / 10 = 1/10 = 0.100

Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.

Which of the following explains why f(x) = log2x

Radda [10]

Answer:

There is no power of 2 that is equal to 0.

Its inverse does not have any x-intercepts.

Step-by-step explanation:

Given the function

$\:\:f\left(x\right)=\log \:_2\left(x\right)$

This function can be written as:

$y=\log _2\left(x\right)$

As the rule tells s that

$\:y=log_ax\Rightarrow \:a^y=x$

$x=2^y\:\:$

As we know that the value of x=0 at y-intercept.

$0=2^y\:\:$

For any value of $y$ , this statement is false as there is no power of 2 that is equal to 0.

Also

Lets interchange x and y in the equation $x=2^y\:\:$ to find the inverse of the function.

$y=2^x\:\:$

So, it doesn't have any x-intercepts as for any value of x, the value of $y$ can not be zero for this function.

Therefore, Its inverse does not have any x-intercepts.
