Answer:
Step-by-step explanation:
In order to identify the equation of line from the given graph, we need to find the slope and the y-intercept.
Slope of a line is the ratio of rise to run or change in over change in .
The y-intercept is a point on the line for which the value is 0. In other words, it is on the y-axis.
Here, from the graph,
y-intercept is at point (0,4). So, y-intercept is the value which is,.
Also, slope is given as,
Therefore, the equation of the line is:

Answer:
The minimum score required for an interview is 73.4.
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:
If test scores are normally distributed, what is the minimum score required for an interview?
Top 25%, which is at least the 100-25 = 75th percentile, which is the value of X when Z has a pvalue of 0.75. So it is X when Z = 0.675.
The minimum score required for an interview is 73.4.
Answer:
about $342 or $171 per airpod
Step-by-step explanation:
the airpods cost about $171 each
1,200 ÷ 7 = 171 x 2 = 342
