Proving that EFGH is a square: points E,F,G,H
separate the sides of the square ABCD into two lines. if AE=BF=CG=DH then
AH=DG=EB=FC and it shows that if we connect the points E,F,G,H to each other with line we will have a square
HAE~EBF~FCG~GDH by rule SAS
(141 + 162 + S) / 3 = 160
(303 + S) / 3 = 160
101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3
S= 177
Jacques needs at least a 177 to get a 160 average

Step-by-step explanation:
Answer:
Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.
Step-by-step explanation:
Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.
We want to find the area between the z-scores of -3 and 3.
The <u>Empirical Rule</u> tells us that 99.7% of the data lies <em>within three standard deviations</em> under the normal curve.
Therefore, the <u>area</u> between <em>-3 < z < 3</em> is about <u>.997</u>, or around <u>99.7%</u>.
