Answer:
Step-by-step explanation:
We are given the following information in the question:
Let x and y be the two addends whose sum is being evaluated.
It is given that the sum is greater than 4 and smaller than 10. This can be written with the help of inequality:
Also, each addend is less than 5. This can the written in the form of inequality:
If we solve these linear inequalities in two variable, we may be able to get the values of x and y.
The common area of the following inequalities gives us the solution to the problem. There could be various values of x and y to give the solution of these inequities.
The value of expression 8 × 6 is,
⇒ 48
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
⇒ 8 × 6
Now, After multiplication, we get;
⇒ 8 × 6
⇒ 48

Answer:
x = -7
Step-by-step explanation:
Start with your given equation.
8x - 2 = -9 + 7x
Next, subtract 7x from both sides of the equation and add like terms.
x - 2 = -9
Finally, add 2 to both sides of the equation and add like terms.
x = -7
Answer:
Step-by-step explanation:
x = -7
account :
8x-2=-9+7x
8x-7x=-9+2
X=-7
To prevent non-response bias, it is generally recommended to aim for a response rate of at least 60% or higher, so MyBook should ideally have at least 1260 surveys returned.
The level of survey response required to prevent non-response bias depends on various factors such as the target population, the survey's objective, and the overall response rate. In general, a higher response rate is preferred to minimize non-response bias. A common rule of thumb is to aim for a response rate of at least 60% or higher.
If a substantial number of surveys are not returned, the results may not accurately represent the opinions and characteristics of the entire target population. For instance, if only 30% of the surveys are returned, it leaves a large proportion of the population unaccounted for, potentially biasing the results towards those who responded.
However, it's essential to consider the context of the survey and the population being surveyed. In some cases, achieving very high response rates might be impractical or unnecessary, especially when dealing with large populations or sensitive topics.
