An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Answer:
translation 2 units left
; reflection across the y-axis
Step-by-step explanation:
The y-coordinates of the points do not change from the pre-image to the image. This means there is no translation down (this would add or subtract to the y-coordinates) and no reflection across the x-axis (this would negate the y-coordinates).
This leaves us with a translation 2 units left and a reflection across the y-axis.
The translation 2 units left adds 2 to the x-coordinates, and the reflection across the y-axis negates the x-coordinates. If we add 2 first, the coordinates would be (-4+2, 6) = (-2, 6); (-2+2, 2) = (0, 2); and (-6+2, 2) = (-4, 2).
Negating each of these would give us (2, 6); (0, 2); and (4, 2). These are the desired image coordinates.
Answer:
We are 90% confident that the true proportion of teenagers who have used at least one informal element in school writing assignments is between 0.464 and 0.518
Step-by-step explanation:
We can begin finding the estimator for the proportion of interest:
The confidence level is 90% , and the significance level would be given by and . And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
Replacing the info given we got:
We are 90% confident that the true proportion of teenagers who have used at least one informal element in school writing assignments is between 0.464 and 0.518
Answer:
radius is 7.16
Step-by-step explanation:
The equation to find the radius of a circle is r=C/2 with C being the circumference, r being the radius
