The given in this
problem are:
99% confidence level
N = 61
Mean = 2.0 kg
Standard deviation = 4.8
Z value for a 9%
confidence interval is 2.576
Confidence Interval = mean
± Z s/ sqrt n
= 2.0 ± 2.576(4.8/sqrt 61)
=2.0 ± 2.576 (0.6145770236779006736364371988794)
= 2.0 ± 1.5832

Answer:
x-intercepts: (-4,0) and (-2,0) y-intercepts: (0,-2)
Step-by-step explanation:
<u>x-intercept</u>:
y = |x+1| - 3
0 = |x+1| - 3
3 = |x+1|
The numbers -4 and 2 are the x-intercepts because if you add -4 and 1, you get the absolute value of -3, which is 3. If you add 2 and 1, you get the absolute value of 3, which is 3.
<u>y-intercept</u>:
y = |x+1| - 3
y = |0+1| - 3
y = |1| - 3
y = 1 - 3
y = -2
Answer:
1 ,5 and 3 is polynomial rest non
Answer:
(x,y) is in the Quadrant II.
Step-by-step explanation:
The Quadrant II contains the x-values that are less than 0 (negative x-values), while the y-values are greater than 0 (positive y-values). Therefore, if x < 0 and y > 0, then point (x, y) must be somewhere in Quadrant II of the Cartesian Plane.
