Answer:
Step-by-step explanation:
From the information given:
For Adult Men
Mean 
= 69.5
Standard deviation 
= 2.4
observed value X = 74
For Adult Women
Mean = 63.8
Standard deviation = 2.6
observed value X = 70
Therefore ; the values for their z scores can be obtained in order to determine who is more unusually tall within his or her respective sex
For Adult Men :
z = 1.875
For Adult Women :
z = 2.3846
Thus; we can conclude that , the women is more unusually tall within his or her respective sex
x + 7 = 2(3x - 4) Remove the brackets
x + 7 = 2*3x - 4*2
x + 7 = 6x - 8 Subtract 7 from both sides.
x + 7 - 7 = 6x - 8 - 7
x = 6x - 15 Subtract 6x from both sides
x - 6x = - 15
-5x = - 15 Divide by -5
-5x/-5 = -15/-5
x = 3
Answer:
13/4
Step-by-step explanation:
To find the slope we use the equation
m= (y2-y1)/(x2-x1)
= (85-20)/(20-0)
= 65/20
= 13/4
Since DE is the perpendicular bisector of JL.
The perpendicular bisector is a line that divides a line segment into two equal parts. It also makes a right angle with the line segment. Each point on the perpendicular bisector is the same distance from each of the endpoints of the original line segment.
Since, a perpendicular bisector is a line that divides a line segment into two equal parts.
So, JK=KL. (which is not given in the option)
Since ED is a perpendicular bisector. So, each point on ED is the same distance from the endpoints of line segment JL.
So, EJ=EL.
Therefore, Option 1 is the correct answer.
Answer:
The area of whole square is 396 sq mm
the area of triangle = 99
396 - 99 = 297 sq mm
Answer - 297
