We Answer:
84.134% of the scores
Step-by-step explanation:
-This questions needs as to determine the probability of scores less than 282 then find the expectation;
-Let X be the score of a random selection:
The probability of scores below 282 is 0.84134 or 84.134%
Hence, 84.134% of the scores were below 282
let's recall that the sum of all interior angles in a triangle is 180°.
an equi-lateral, equal sides, triangle has all sides that are equal.
sides that are equal will yield an equal opposite angle.
so if all sides are equal, all angles are equal, for a sum of 180°, that's only possible with 60°, 60° and 60° angles, and all of them are acute, none obtuse.
Step-by-step explanation:
because we can also find out the value of x in second equation like this
3x=21
x=21/3
x=7
No, bc the lower quartile should be in between the minimum and middle quartile(median) Hoped this helped!
X = 80 + 20 = 100 degrees
