Step-by-step explanation:
Mean average = (84 + 72 + 90 + 95 + 87) / 5 = 85.6
For the mean score to increase, the new score must be greater than 85.6.
Hence the correct options are 90, 86 and 92.
Hi there!
There are four different types of transformations:
-Reflections
-Translations
-Rotations
-Dilations
In a reflection, the shape is simply reflected across a line of reflection. It does not change size or shape, so therefore it is a congruence transformation.
In a translation, the shape is moved up, down, left, or right. It does not change size or shape, so therefore it is a congruence transformation.
In a rotation, the shape is rotated around a point of rotation. It does not change size or shape, so therefore it is a congruence transformation.
In a dilation, the shape is made larger or smaller by a scale factor. It does change size, so therefore it is not a congruence transformation.
The transformation that is not a congruence transformation is a DILATION.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Type of error: <u>Run-on(comma splice).</u>
Best revision to fix it: <u>Adding a semicolon after beginners
</u>.
Explanation:
A run-on sentence is described as a sentence in which two independent clauses are joined inappropriately. It could be either comma splice where the two independent clauses are incorrectly linked using a comma or fused sentence when the two clauses run-on without employing appropriate coordinating conjunction or punctuation marks to separate the two ideas.
In the given sentence, it exemplifies a comma splice type of run-on sentence error. To fix this error, a semicolon after 'beginners' can be employed instead of a comma. This <u>will help in connecting the two ideas appropriately where the first idea leads the second</u>. Thus, the final sentence reads as:
'The guitar is another excellent instrument for beginners; however, it takes more practice than a recorder.'
