Answer:-23/16
Step-by-step explanation:
-15/16+-1/2
-15/16-1/2 Lcm of 16 and 2=16
(-15-8)/16
-23/16
25 because 29 and 34 are in the middle so on the other side the middle number will be 25
It would be 1

(d) 6 / 6 = 1
Answer:
A
Step-by-step explanation:
The data is from 75 to 100,
and the whiskers also go from that same data
The median is 93 which means the line will go there
90 + 96 = 186 / 2 = 93
The box goes from 88 to 98 because it includes the upper and lower quartile, and allows room for the middle two numbers to become the median and split the data.
Answer:
Part 1) The measure of the exterior angle is 128°
Part 2) The measure of angle x is 30°
part 3) The value of x is 25 units
Step-by-step explanation:
Part 1)
step 1
Find the measure of the third internal angle of the triangle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
Let
c----> the measure of the third internal angle
42+(9x-4)°+c°=180°
c=180°-42°-9x+4°
c=142°-9x
step 2
Find the value of x
we know that
c+(12x+8)°=180° ----> by supplementary angles
substitute
142°-9x+(12x+8)°=180°
3x=30°
x=10°
step 3
Find the measure of the exterior angle
(12x+8)°=(12(10)+8)°=128°
Part 2) Find the value of x
The figure show a equilateral triangle ( has three equal internal angles and three equal sides) and an isosceles triangle ( has two equal internal angles and two equal sides)
Remember that
The internal angles of a equilateral triangle is 60 degrees
so
The vertex angle of the isosceles triangle is equal to
180°-60°=120° ----> by supplementary angles
therefore
The base angle of the isosceles triangle is equal to
2x+120°=180°
2x=60°
x=30°
Part 3) we know that
if AB is a midsegment
then
(4x-10)/2=45
solve for x
4x-10=90
4x=100
x=25 units
