Answer:
Step-by-step explanation:
For this case we want to find this probability:
Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:
The other possibility is use the normal standard table and we got a similar result.
Answer:
<h3>The answer is option B</h3>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find an equation of a line given two points first find the slope / gradient
Slope of the line using points (-1,4) and (-2,2) is
So the equation of the line using point (-1,4) is
<h3>y - 4 = 2( x + 1)</h3>Hope this helps you
