C.) 3 points because you can't have 2 points on the same y axis line.
Step-by-step explanation:
When X is - 5 then y is 3
When X is-1 then y is - 2
When X is 3 then y is -4
Answer:
The reading speed of a sixth-grader whose reading speed is at the 90th percentile is 155.72 words per minute.
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:

What is the reading speed of a sixth-grader whose reading speed is at the 90th percentile
This is the value of X when Z has a pvalue of 0.9. So it is X when Z = 1.28.




The reading speed of a sixth-grader whose reading speed is at the 90th percentile is 155.72 words per minute.
Answer:
P = 2(x + 5) + 2(2x - 3)
Step-by-step explanation:
GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate?
The shape of the gate is rectangular.
Hence, the Perimeter of a rectangle (the gate) = 2L + 2W
Where :
L = GR = x + 5
W = GP = 2x - 3
Hence,the perimeter of the gate is
P = 2(x + 5) + 2(2x - 3)
