The answer is !5/ 4 because when dividing a fraction by a fraction you multiply the first fraction by the second fractions reciprocal.
Wilson's question is not a statistical question because the students my not a have tall person in their class
there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29
145-29=116
116 is this year number of boys on honor role
For girls.
=0.25*60=15
60-15=45
45 is this year number of girls on honor role.
Total number of students on honor role this year is 116+45 =161
Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100
= 0.215*100
= 21.5%
The resulting triangle is a right triangle with the third side given:
First, the angle can be solved using the given rise and run of the cable. So,
tan θ = 2 / 5
θ = 15.95°
Next, the lengths b and c can be solved using the solved angle:
tan 15.95 = 1320 / b
b = 3300 ft
The hypotenuse or c can be solved by trigonometric functions or using Pythagorean theorem, using the sine function:
sin 15.95 = 1320 / c
c = 4804 ft
