Answer:
C. Correct
Step-by-step explanation:
The interpretation of a confidence interval of x% is that we are x% that this interval contains the mean of the population.
So, for example, the interpretation of a confidence interval of 95% is that we are 95% that this interval contains the mean of the population.
In this problem, we have that:
Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 41.5 and upper bound: 45.6.
Also, the following affiration:
(A) There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 41.5 hours and 45.6 hours.
This is correct
So, the answer is:
C. Correct
3-5w+12+2w-3
(3+12-3)=12
(-5w+2w)=-3w
-3w+12
Answer:
+4
Step-by-step explanation:
any opposite of a natural number is created with a "minus"
- (-4) = +4
The scale factor from Figure A to Figure B is 4
<h3>How to determine the
scale factor from Figure A to Figure B?</h3>
From the question, we have the following statement:
Figure B is a scaled copy of Figure A.
The corresponding side lengths of figure A and figure B are:
Figure A = 10
Figure B = 40
The scale factor from Figure A to Figure B is then calculated as:
Scale factor = Figure B/Figure A
Substitute the known values in the above equation
Scale factor = 40/10
Evaluate the quotient
Scale factor = 4
Hence, the scale factor from Figure A to Figure B is 4

Answer:
C. Directrix and Focus
Step-by-step explanation:
Given choices are :
A. Locus and Directrix
B. Axis and vertex
C. Directrix and Focus or
D. Vertex and Locus
Now we need to find about which of the above choices are the exact same distance from a parabola.
By definition of parabola, vertex lies at equal distance from directrix and focus.
Hence choice C. Directrix and Focus is correct.
