Answer:
x = 11
Step-by-step explanation:
Median = The middle value of the set
There are 8 data values in the data set. You can split it up by 2 in order to get 4 and 4. There are two middle numbers that make up the median
3 4 7 9 x 12 14 18
We know that in order to find the median, we have to divide the two numbers by 2. If the median is 10, 10 by 2 equals 20. 9 plus 11 equals 20,
3 4 7 9 11 12 14 18
x = 11

Answer:
a. 12 cm
b. 90°
c. 60°
Step-by-step explanation:
The relevant relationships are ...
- all sides of a rhombus have the same length
- the diagonals of a rhombus are perpendicular bisectors of each other
- the diagonals of a rhombus divide the figure into 4 congruent triangles
__
a) The perimeter, 48 cm, is the sum of four equal side lengths, so any given side is (48 cm)/4 = 12 cm.
GH = 12 cm
__
b) Angle EJF is where the diagonals meet. It is a right angle.
∠EJF = 90°
__
c) Angle EFJ is the complement of the one marked, so is 30°. Angles EHJ and GHJ are congruent to that, so both are 30°. Angle EHG is the sum of those two congruent 30° angles, so is ...
∠EHG = 60°
Answer:
x = (-9)/2 or decimal x = -4.5
Step-by-step explanation:
Solve for x:
4 x + 18 = 0
Subtract 18 from both sides:
4 x + (18 - 18) = -18
18 - 18 = 0:
4 x = -18
Divide both sides of 4 x = -18 by 4:
(4 x)/4 = (-18)/4
4/4 = 1:
x = (-18)/4
The gcd of 18 and 4 is 2, so (-18)/4 = (-(2×9))/(2×2) = 2/2×(-9)/2 = (-9)/2:
Answer: x = (-9)/2
