Step-by-step explanation:
I think it is not true because all sides are triangle except the one on the bottom is a square
Answer:
0.989
Step-by-step explanation:
The formula for Margin of Error is:
z × Standard deviation/√n
Where
z = z score for 99% confidence Interval
= 2.576
n = 61 people
Standard deviation = $3
Hence,
Margin of Error
= 2.576 × 3/√61
= 0.989
Answer: C y= -3/2x + 11
Step-by-step explanation:
So you have to know the parallel lines have the same slopes but different y- intercepts. so we will use the same slopes but we will calculate the y -intercept.
in the points (4,5) 5 is the y value and 4 is the x value. and we will plot it into the formula y=mx + b where m is the slope and we already know the slope is -3/2 but we need to find the y intercept.
5 = -3/2(4) + b
5= -6 + b
+6 +6
b= 11 so now we know the y intercept is 11 so the equation will be y= -3/2x + 11
