Answer:
2.8
Step-by-step explanation:
Answer:
The "3y" in the first term is a factor
The "9" in the second term is a coefficient
The "(7 + 2x)" in the first term is a factor
Step-by-step explanation:
Given in the question an expression
3y(7 + 2x) + 9xy - 10
- The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>
6y
6 is coefficient
2.Constants are terms without variables
<h3>Example</h3>
10
3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.
<h3> Example</h3>
(4x+1)(3x+7)
(4x+1) and (3x+7) both are factors
Answer:
8.93
Step-by-step explanation:
(pls mark me brainliest if u can)
Add 5 on both sides and it will give you ×=-10
Answer:
The population variance and population standard deviation are used when calculating for a population while the sample variance and sample standard deviation are used when calculating for a sample
Step-by-step explanation:
A population is defined as all members of a specified group or simply Population is the whole group. A sample is a part of a population that is used to describe the characteristics, The size of a sample can be less than 1%, or 10%, or 60% of the population.
The population variance and population standard deviation are used when calculating for a population while the sample variance and sample standard deviation are used when calculating for a sample. sample variance(or standard deviation) will be slightly higher than that of the population variance(or population standard deviation) for the same problem if solved. The purpose of this little difference it to get an accurate estimate of the population‘s variance to compensate for the fact it is a sample rather than with the whole population.
