Answer:

lcm for cuberoot

2*2*2*5*5*5*3*3*3

for cuberoot we will make pairs of common three numbers and write them one time

2*5*3

check 30*30*30=27000

cube

multiply 27000 three times with itself

19683000000000.0 is the answer

Help me with my math please

klio [65]

Answer:

First, let's do a fast definition of a function.

A function is a relation that maps elements from a given set (the domain, is the set of the inputs, usually represented with the variable x) into elements of another set (the range, which is the set of the outputs, usually represented with the variable y)

The functions can map each element of the domain into only one output.

Now, let's solve the problem:

For the vertical table, we can see that the values of x are:

{1, 2, 3} This is the domain.

And the values of y are:

{4, 6, 8} This is the range.

This relation represents a function.

For the horizontal table, we can see that:

The inputs are:

{4, 5} (notice that the 4 is two times there) This is the domain.

And the outputs are:

{2, 3, 4} This is the range.

Here we can see that this relationship maps the input "4" into two different outputs, then this is not a function.

2) We want to know if the graph represents a function.

The first thing we can see is that if we draw a vertical line in some places, the line will touch the graph at two different points. This means that one single value of x can be mapped into two different values of y.

And as we already said, a function maps each input into only one output, then the graph does not represent a function.

A person must score in the upper 7% of the population on an admissions test to qualify for membership in society catering to hig

olya-2409 [2.1K]

Answer:

The minimum score a person must have to qualify for the society is 162.05

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

Test scores are normally distributed with a mean of 140 and a standard deviation of 15. This means that $\mu = 140, \sigma = 15$ .

What is the minimum score a person must have to qualify for the society?

Since the person must score in the upper 7% of the population, this is the X when Z has a pvalue of 0.93.

This is $Z = 1.47$ .

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

$1.47 = \frac{X - 140}{15}$

$X - 140 = 15*1.47$

$X = 162.05$

The minimum score a person must have to qualify for the society is 162.05

Margaret is dividing 829 by 4. Explain why Margaret needs to write a zero in the tens place of the quotient

aliina [53]

Quotient is the number gotten when you divide a number by a diviser.
In this case our number is 829 and the diviser is 4, and the quotient is 207.25. When the first digit 8 is divided by 4, we get 2, then since the second digit 2 is less than four we must put zero on the tens digit of the quotient so that we can pick the third digit 9 to form 29 which is greater than 4,and the process continues ...
