Answer:
3 r 4
Step-by-step explanation:
22/6= 3.6 recurring so we round down (3.6 → 3)
so 3 remainder 4.
The remainder means left-overs known as 'r'.
The midpoint of that segment is (-8,-8).
The anchor point would be placed at the center of the triangle. In order to find this point, you have to construct three angle bisectors. Start from one vertex and intersect it to the midpoint of the opposite side. These angle bisectors are drawn in blue lines. The intersection of these bisectors, represented by the red dot, is the anchor point.
You have to use the formula to find the area of the triangle Remember,the area equation is b times h to the b divided by 2.Doing this will get you 600 m.
Answer:
(52.30 ; 52.62)
Step-by-step explanation:
Given :
Sample size, n = 20
Mean, xbar = 52.46
Standard deviation, s = 0.42
We assume a t - distribution
The 90% confidence interval
The confidence interval relation :
C.I = xbar ± Tcritical * s/√n
To obtain the Tcritical value :
Degree of freedom, df = n - 1 ; 20 - 1 = 19 ; α = (1 - 0.90) /2 = 0.1/2 = 0.05
Using the T-distribution table, Tcritical = 1.729
We now have :
C.I = 52.46 ± (1.729 * 0.42/√20)
C. I = 52.46 ± 0.1624
C.I = (52.30 ; 52.62)
