Answer:
Step-by-step explanation:
5x-2y-12=0
5x-2y+12-12=0+12
5x-2y=12
5x-5x-2y=12-5x
-2y=12-5x
(-2y)/-2=(12-5x)/-2
y=5/2x-6
slope= 5/2x up 5 over 2
y-intercept is -6
1 liter equals to 1000 milliliters
1000 - 375 equals 625 ml
1/4 + 1/2 is 3/4. the equivalent fractions would be 1/4 + 2/4 or 3/4
Answer:
1.25 miles.
Step-by-step explanation:
Let x be the length of trail. We have been given that after Paul hiked of a mile, he was of the way along the trail.
Let need to find x such that of x equals .
Therefore, the trail is 1.25 miles long.
Answer:
Replacement time of 10.064 years.
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 replacement time that separates the top 18% from the bottom 82%.
This is the value of X when Z has a pvalue of 0.82. So it is X when Z = 0.915.
Replacement time of 10.064 years.
