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
Answer:
56.1 cm²
Step-by-step explanation:
In any circle the area (A) of a sector is
A = area of circle × fraction of circle
= πr² × 
= π × 8.91² × 
=
≈ 56.1 cm²
In order to know that, you need to divide 28 from 126
It would be:126/28 = 4.5
So, your final answer is 4.5
Hope this helps!
Answer:
all of them except straight and reflex
Step-by-step explanation:
when angles are supplementary it means that they add up to 180
an acute angle is supplementary to an obtuse angle
an obtuse angle is supplementary to an acute angle
a right angle is supplementary to a right angle
but a reflex angle is over 180 so it's not supplementary to anything
and a straight angle is already 180 so it has no supplements either
Answer:
18 years
Step-by-step explanation:
Rule of 72
(72)/(interest)=years to double
72/4=18
