5x = -1
x = -1/5 = -0.2
That means that any ordered pair for the line will be (-0.2, y)
You can put any number in for y.
So two ordered pairs could be:
(-0.2, 1)
and
(-0.2, 2)
Answer:
Z scores between -0.995 and 0.995 bound the middle 68% of the area under the stanrard normal curve
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.
Middle 68%
Between the 50 - (68/2) = 16th percentile and the 50 + (68/2) = 84th percentile.
16th percentile:
X when Z has a pvalue of 0.16. So X when Z = -0.995
84th percentile:
X when Z has a pvalue of 0.84. So X when Z = 0.995.
Z scores between -0.995 and 0.995 bound the middle 68% of the area under the stanrard normal curve
Answer: $2.67 per person
Step-by-step explanation: Well hello again, so the question said two of his friends had an emergency now there are three people left going to New York including Eric himself. So, the equation is 8 ÷ 3 = ?. Now we solve the equation 8 ÷ 3 = ? which is $2.67.
Answers:
- Red = 1/3
- Yellow = 7/15
- Blue = 1/5
====================================================
Explanation:
Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.
- Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3
- Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15
- Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5
(2)2+1=5
3(1)+1=4 is your answer
