Make a number line and mark the points that represent the following values of x. −5≤x≤34
1 answer:
The expression −5 ≤ x ≤ 34 is an inequality expression
<h3>How to draw the number line</h3>The expression is given as:
−5 ≤ x ≤ 34
This can be split as follows:
−5 ≤ x and x ≤ 34
The inequalities used in the expression are less than or equal to.
This means that the endpoints of the inequality are inclusive of the values of x.
So, the value of x starts from -5, and it ends at 34

Answer:
The minimum score needed to be considered for admission to Stanfords graduate school is 328.48.
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:
What is the minimum score needed to be considered for admission to Stanfords graduate school?
Top 2.5%.
So X when Z has a pvalue of 1-0.025 = 0.975. So X when Z = 1.96
The minimum score needed to be considered for admission to Stanfords graduate school is 328.48.
