G
Answer:
The answer is 37
Step-by-step explanation:
180- 143= 37
The scale factor is 5
In the first image, you can see that the pre image square it 1 unit long and the image is 5. How do you get 1 to 5, you multiply by 5. So the scale factor is 5.
Answer: Choice A
The axis of symmetry for the function is x = 0.
===========================================================
Explanation:
The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).
This parabola may have 0 roots, 1 root, or 2 roots.
Answer:
c. 9.5 lb < mu < 11.1 lb.
Step-by-step explanation:
Confidence interval can be stated as M±ME where
- M is the sample mean (10.3)
- ME is the margin of error
margin of error (ME) around the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- s is the standard deviation of the sample (2.4)
- N is the sample size (37)
Putting thesenumbers in the formula we get:
ME=
≈ 0.7733 ≈ 0.8
Then the 95% confidence interval would be 10.3 ± 0.8
