Answer:21
Step-by-step explanation:12 times three is 36 and 7 times 3 is 21
Answer:
a=-0.5
Step-by-step explanation:
Distributive property for left side, difference of squares for right side.
8a-9a^2=-40+36-9a^2
-9a^2 cancels out
8a=-4
a=-0.5
Answer: 601
Step-by-step explanation:
When the prior estimate of population proportion is not given , the formula we apply to find sample size :

, where z* = critical z-value
E=Margin of error
Given : Margin of error = 0.04
Confidence level = 95%
We know that , according to the z-table , the critical value for 95% confidence interval = z*= 1.960
Then, the required sample size : 


Hence, the required minimum sample size = 601
Sum of interior angles formula = (n-2) x 180
where n = number of sides
so,
( 19-2 ) x 180
= 17 x 180
= 3060
ans : A

Answer:
<em>Slope - intercept form y = 5x+17</em>
<em>The equation of the parallel line to the given line is 5x-y +17=0</em>
Step-by-step explanation:
<u><em>Explanation</em></u>
The equation of the straight line is y= 5x+2
5x - y +2=0
The equation of the straight line is 5x-y+2=0
Given that the point(-3,2)
The equation of the parallel line to the given line is
5x -y +k=0
5(-3) - 2+k=0
-15 -2 +k =0
-17 +k=0
k =17
The equation of the parallel line to the given line is 5x-y +17=0
<u><em>Final answer:-</em></u>
<em>Slope - intercept form y = mx+c</em>
<em>Slope - intercept form y = 5x+17</em>
