Answer:
(3,1) ; (6,-2)
Step-by-step explanation:
We have to search the points that the line and the parabola have in common, that are the points where they intercept
(3,1) ; (6,-2)
40,829,000 = 40,000,000 + 800,000 + 20,000 + <span> 9,000
hope it helps</span>
C because the <span>interquartile range is the number in the middle but ther is no middle so what is between 70 and 80 it is 75</span>
Answer:
The answer is B
Step-by-step explanation:
Problem 1
Step 1 write the equation
Step 2 what you do to one side you have to do to the other side. + 8x to both sides.
Step 3 Divide by 4 on both sides. Answer for that would be 4y=20/4+8x/4
Step 4 y=5+2x
problem 2
I cant do sorry
Answer:
The limit that 97.5% of the data points will be above is $912.
Step-by-step explanation:
Problems of normally distributed samples can be 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 limit that 97.5% of the data points will be above.
This is the value of X when Z has a pvalue of 1-0.975 = 0.025. So it is X when Z = -1.96.
So
The limit that 97.5% of the data points will be above is $912.
