A to the middle one
B to the top one
C to the bottom one
The top one is all real numbers because any number in the "l l" absolute brackets will come out to be positive, example: l-3l=3 and l3l=3. Thats going to be equal to and since the sign says "less than or equal to" that will work.
The middle one is only positive solutions because for 7x to be more than lxl it would need to be positive since the sign is "greater than"
The bottom one is none because the absolute of anything will always be more than a negative since the absolute is always positive. Never less or equal to a negative, always more.
Answer:
70 is answer
Step-by-step explanation:
Given that a function in x is
we have to find f'(7)
we know by derivative rule derivative of a function is
For finding out at 7 we replace x by 7
=
So f'(7) = 70
answer is 70
Answer: 
Step-by-step explanation:
Given : A random sample of 700 home owners in a particular city found 112 home owners who had a swimming pool in their backyard.
i.e. n= 700 and x= 112
Sample proportion : 
z-value for 95% confidence interval : 
Now, the 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard will be :-
Hence, 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard :
Answer:336
Step-by-step explanation:5 times 6 is 24 and 24 times 14 is 336
Answer: 63 degrees.
1. The Vertical Angles Theorem marks “x” as equivalent to its opposite angle (Angle A).
2. Angle A is apart of a 90-45-45 right triangle (since Angle B is 90 degrees).
3. Angle A and C are equivalent because of the 45-45-90 relationship.
4. Angle C is the vertical angle of the angle measuring 63 degrees.
5. So Angle X=Angle A=Angle C= 63 degrees.
