Answer:
Therefore, the solutions of the quadratic equations are:
The graph is also attached.
Step-by-step explanation:
The solution of the graph could be obtained by finding the x-intercept.
Finding the x-intercept by substituting the value y = 0
so
∵ y = 0
So, when y = 0, then x values are 3, and 5.
Therefore, the solutions of the quadratic equations are:
The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.
You can do any problem first because they will all come out to be the same answer. The property that I am going to be using for all of them is commutative property of multiplication. -5*1=-5 is the first step you could do. -5*4=-20, it doesn't matter is you skip a number or not it will be okay. -20*11=-220. You can start with any one and the answer will still be -220.
Divide seven by eight. the answer is 0.875, or 0.88 if you round to the hundreth place.
Answer:
b). Reject the null hypothesis and conclude the means are different.
Step-by-step explanation:
A hypothesis is characterized as null when the data/statistics display that there is no distinction between the particular features of the groups. As per the details provided, the decision would be to 'reject/deny the null hypothesis and deduce that the means of the processes are different.' This <u>shows that there is no association among the variables due to the distinction in the means of the two processes and other data provided</u>. Thus, <u>option b</u> is the correct answer.
