Answer:
y=3x-8
Step-by-step explanation:
If the line is parallel to y=3x+3, that would mean that they would have the same slope of 3. Then, once you plug it back into the equation along with the point given, you would get 1=3(3)+b. Solve from there, and you get b= -8. In conclusion, your point slope formula comes out to be y=3x-8.
Hope this helps! :)
we have the list
12, -4, -9,2, -2
rewrite in increasing order from left to right
The answer is
<h2>-9,-4,-2,2,12</h2>
Answer:
= (- 475)
Step-by-step explanation:
Given:
(-5) × (-5) × ... × (-5) = (-5)95
Find:
Sign of the product
Computation:
(-5) × (-5) × ... × (-5) = (-5)95
= (- 475)
No, it is not compulsory to do all calculation to find sigh of product
Negative number × odd time = Negative number
Negative number × even time = Positive number number
Answer:
16/3 or 5.33
Step-by-step explanation:
Cross multiply
4/1 * 3/4
4 * 4 = 16
3 * 1 = 3
Answer:
a)
90% confidence interval for the mean grading time of all composition papers.
(12.47981 , 13.52019)
b)
Appropriate inequality
The interval is ( 12.47981 < μ < 13.52019)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
a)
Given sample size 'n' = 40
Mean of the sample = 13 minutes
standard deviation = 2 min
level of significance = 0.10 or 90%
90% confidence interval for the mean grading time of all composition papers.
( 13 - 0.52019 , 13 + 0.52019)
(12.47981 , 13.52019)
b)
The interval is ( 12.47981 < μ < 13.52019)
