Answer:
Step-by-step explanation:
Calculate z-score firstly
z-score = (x-mean)/SD = (2.75-2.5)/0.25 = 0.25/0.25 = 1
P( x greater than or equal to 2.75) = P(z greater than or equal to 1)
= 1 - p(z <1)
P(z<1) from table = 0.84134
1-p(z<1) = 0.15866 or 15.866%
Answer:
26.69 square meters
Step-by-step explanation:
A=r(3.14)
A= 8.5(3.14)
A=26.69 meters
the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
558,739 is the correct answer.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We know that:
First, we need to change the 'y' sign.
- => -y = -x + 6
- => y = x - 6
Now, let's compare both of the equations to find slope.
- => (y = x - 6) = (y = mx + b)
We can see that the slope is 1 and the y-intercept is -6.
<u>Conclusion:</u>
Therefore:
Hoped this helped.
