Answer:
y=2x-1
Step-by-step explanation:
y=mx+b
insert Point (0,-1)
-1 = m * 0 + b
-1 = b
slope:
m = delta y / delta x
m = 2 / 1
m = 2
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.'
Answer: The proportion of new car buyers that trade in their old car has statistically significantly decreased.
Step-by-step explanation:
Since we have given that
p = 48% = 0.48
n = 115
x = 46
So, 
So, hypothesis would be

So, test value would be

At 10% level of significance, critical value would be
z= 1.28
Since 1.28 < 1.72
So, we will reject the null hypothesis.
Hence, the proportion of new car buyers that trade in their old car has statistically significantly decreased.
Answer:
