Answer:
Well to start with, a coefficient is a number that is placed before a variable. In this case we have 10x+8, so the coefficient is well 10.
Step-by-step explanation:
Answer:
numbers ABC sign <u>each</u><u> </u><u> </u><u> </u><u>following</u><u> </u><u> </u><u>find</u><u> </u><u>formula</u><u> </u>
Percent is parts out of 100 so
45%=45/100=9/20
'of' means multiply
18 =9/20 times something
multiply both sides by 20/9 to clear fraction
360/9=something
40=something
the value is 40
Step 1. Solve both inequalities for

:




Step 2. To check a point in the solution of the given system of inequalities, look for the intercepts of the lines

and

:

(1)

(2)
Replace (1) in (2):

Solve for

:


(3)
Replace (3) in (1):



We can conclude that the point (-2,3) is in the solution of the system if <span>
inequalities</span>
; also any point inside the dark shaded area of the graph of the system of inequalities is also a solution of the system.
Answer:
B- It cannot be answered without additional information.
Step-by-step explanation:
From the question, we have α= 0.01 and α= 0.05.
Thus;
We can decide to look at the critical values and check if test statistic is less or more than the tabulated value for α= 0.01 and 0.05.
However, that will not be sufficient as neither the level of significance nor confidence level is clearly mentioned in the question and thus, we can not answer it without additional information.
