Answer:
7 square units
Step-by-step explanation:
As with many geometry problems, there are several ways you can work this.
Label the lower left and lower right vertices of the rectangle points W and E, respectively. You can subtract the areas of triangles WSR and EQR from the area of trapezoid WSQE to find the area of triangle QRS.
The applicable formulas are ...
area of a trapezoid: A = (1/2)(b1 +b2)h
area of a triangle: A = (1/2)bh
So, our areas are ...
AQRS = AWSQE - AWSR - AEQR
= (1/2)(WS +EQ)WE -(1/2)(WS)(WR) -(1/2)(EQ)(ER)
Factoring out 1/2, we have ...
= (1/2)((2+5)·4 -2·2 -5·2)
= (1/2)(28 -4 -10) = 7 . . . . square units
Answer:
1 Lawn per 3 Hours
Step-by-step explanation:
In 'Lawns : Hours' the work that she has done = 4 : 12 = 1 : 3
With this workout, we can conclude that Maya mowed 1 Lawn every 3 Hours.
95% confidence interval is given by
x - 2D , and x+ 2D
For 99% confidence interval is
x - 3D , and x + 3D
x = 100000
D = 2000
Then calculate
100000 - 3•2000= 94000
and
100000 + 3•2000= 106000
Now find √D = 44.72
Then interval is
100000 - 44.72 ,. And. 100000 + 44.72
99,956 lower limit and. 100472 upper limit
Then we see that theres only one interval ,
that is between thes 2 limits
