Answer:
The z-score for the trainee is of 2.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean of the test scores is 72 with a standard deviation of 5.
This means that 
Find the z-score for a trainee, given a score of 82.
This is Z when X = 82. So



The z-score for the trainee is of 2.
Answer:

Step-by-step explanation:
Answer:
b/15 = 13/5
Step-by-step explanation:
The complete question in the attached figure
we have that
f(x)=x²-5x+6
and <span>g(x) has a vertex at (2,4) and the parabola opens downwards
using a graph tool
see the attached figure
</span><span> statements
a) </span><span>The y-intercept of function f is less than the y-intercept of function g
this is not correct, because the </span>y-intercept of function f is greater than the y-intercept of function g
b) <span>The minimum of function f is at (-5,6)
this is not correct, because the minimum of function f is at (2.5,-0.25)
c)</span><span>The y-intercept of function f is greater than the y-intercept of function g
this is correct
d) </span><span>The minimum of function g is at (2,4)
this is not correct because the maximum of function g is </span>(2,4)
the answer is the option
The y-intercept of function f is greater than the y-intercept of function g
Answer:
B y = (-7/4)x - 7
Step-by-step explanation:
Slope intercept form is
y = mx + b
Where m is the slope and b is the y-intercept
m = rise/run
m = ∆y/∆x
m = (y₂ - y₁) / (x₂ - x₁)
m = (-7 - 0) / (0 - -4)
m = -7/4
From the graph the y-intercept
b = -7
-------------------------
y = (-7/4)x - 7
