borishaifa [10]

Answer:

GCF = 5

Step-by-step explanation:

Given:

The numbers are given as:

10, 30 and 45

A factor of a number is a number by which the given number is evenly divisible.

Example: 2 is a factor of 4 as $4\div 2 =2$ . So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.

Now, factors of 10 = 1, 2, 5, 10.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 45 = 1, 3, 5, 9, 15, 45.

So, the greatest common factor in all the three numbers is 5.

Hence, the greatest common factor of 10, 30 and 45 is 5.

Elodia [21]

Answer:

C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number

Step-by-step explanation:

Rational function: In mathematics, the term "rational function" is determined as any specific function that can be described through any "rational fraction", in other words, an algebraic fraction, involving both the denominator and the numerator are considered as polynomials. Therefore, the coefficients of specific polynomials are ought not to be in rational numbers and can be considered in the K field.

In the question above, the given statement represents option C is correct.

Students went on a picnic. They recorded a list of the number of animals

lorasvet [3.4K]

Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.

Step-by-step explanation:

It is imperative to create a data in a tabular column before analyzing.
Once the data is created use tally marks or frequency distribution.
Frequency distribution helps the data to provide occurrence of event.
Very important to number which is a counting numbers are discrete.
Continuous of data are ones which are in decimal.
Descriptive statistics is the 1st level of Statistics.
It finds, where the data stands. Minimum, Maximum is understandable.
Range is at what level data is expanded.
Average is the one numeric of a number.
Median is the mid point of data
Mode is the repetitive number of the data.
Skewness is whether data is having extreme directions.

Diano4ka-milaya [45]

Simplify the expression

$(5*10^5)^-2$

It can be simplified as below:

$(5*10^5)^{-2}=\frac{1}{(5*10^5)^2} \\\\(5*10^5)^{-2}=\frac{1}{25*10^{10}} \\\\(5*10^5)^{-2}=\frac{1}{25}*10^{-10}\\\\ (5*10^5)^{-2}=0.04*10^{-10}\\$
