Answer:
1/3.
Step-by-step explanation:
The slope of the given line = (-4 - -7)/(2-3)
= 3 / -1
= -3.
The line perpendicular to this has slope - 1 / (-3)
= 1/3.
Yes. Then the formula of the resultant water will be: 4H₂O
That, means four molecules of water.
Answer:
0.7823 = 78.23% probability that a truck drives less than 118 miles in a day.
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.
Trucks in a delivery fleet travel a mean of 90 miles per day with a standard deviation of 36 miles per day.
This means that
Find the probability that a truck drives less than 118 miles in a day.
This is the pvalue of Z when X = 118. So
has a pvalue of 0.7823
0.7823 = 78.23% probability that a truck drives less than 118 miles in a day.
So she has <span>12 dogs toys because if she has three dogs and they are a fourth of the total you can just multiply 3 four times.
do you get it?
