Answer:
0.8770
Step-by-step explanation:
We are dealing with a mean of a sample, so we use the formula
![z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B%5Cbar%7BX%7D-%5Cmu%7D%7B%5Csigma%20%5Cdiv%20%5Csqrt%7Bn%7D%7D)
Our mean, μ, is 174.9 and our standard deviation, σ, is 35.2. Our sample size, n, is 35. To find P(X > 168),
z = (168-174.9)/(35.2÷√35) = -6.9/(35.2÷5.9161) = -6.9/5.9499 = -1.16
Using a z table, we see that the area under the curve to the left of this value is 0.1230. However, we want the area to the right; this means we subtract from 1:
1-0.1230 = 0.8770
Answer:
y=-2/3 x +2
y=-x+2
Step-by-step explanation:
slope intercept form : y=mx+b
first find the slope :
two points from the graph : (0,2) (3,0)
y=b=2 when x=0 y = the constant b
m=(y2-y1)/(x2-x1)
m=0-2/3-0
m=-2/3
<h2>y=-2/3 x +2</h2>
question 26: two points from graph: (0,2),(1,1)
b=2 ( when x=0, y=b=2)
m=1-2/1-0
m=-1
<h2>y= - x+2</h2>
