X-5/x<4
times both sides by x
x²-5<4x
minus 4x both sides
x²-4x-5<0
factor
(x-5)(x+1)<0
hmm
special points at x=-1 and x=5
when x=-2, we get 10<0 which is false
when x=0, we get -5<0 which is true
when x=6, we get 7<0 which is false
so the solution must be the range between -1 and 5
so if x<0
whaat
just pick the 3rd grah
6.5 because you add up all your numbers and then divide by the amount of numbers you added
5+0+12+9=26
26/4=6.5
Answer:
No
Step-by-step explanation:
Speed: 300 mi/hr, Gives how fast you go
Velocity: 300 mi/hr west, includes speed and direction
Acceleration: No, it does not say a starting speed or if it was a constant speed.
Hope this helps :)
Answer:
n = 98, that is, she scored at the 98th percentile.
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
She scored 38, so 
Test scores are normally distributed with a mean of 25 and a standard deviation of 6.4.
This means that 
Find the percentile:
We have to find the pvalue of Z. So



has a pvalue of 0.98(rounding to two decimal places).
So n = 98, that is, she scored at the 98th percentile.
