B I would guess it’s kinda hard to understand
Answer:
The minimum score required for an A grade is 92.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the minimum score required for an A grade.
Top 6%, so at least the 100-6 = 94th percentile, which is the value of X when Z has a pvalue of 0.94. So X when Z = 1.555. So
The minimum score required for an A grade is 92.
Answer:
x<= 2
Step-by-step explanation:
4x-24x+30>+8-8x
-12x-24x+30>=8
-12x>=-24
x<-2
The zeros of this functions are -4, 2, -4, and -4.
-4 is a multiple zero and has multiplicity 3.
2 is a zero. I would call it a simple zero, since it's only a zero once (AKA has multiplicity of 1).
Is this a "pick one answer" or "pick all correct answers"?
The slope intercept form of a straight line is
y = mx + c where m = slope and c = y-intercept
so here we have c = 3.
and
y = mx + 3
WE can find the slope m as follows
m = (5-3) / ( 4 - 0) = 2/4 = 1/2
So our equation is
y = 1/2 x + 3
or we could write it as
2y = x + 6
or
-x + 2y = 6 (standard form)
