Answer:
–9 < x – 4 < 9
Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06

Answer:
Population density =
Step-by-step explanation:
The attached figure shows the dimension of an island.
Population density is equal to total population per unit land area.
Firstly we will find the area of the triangle using Pythagoras theorem as follows :
H is Hypotenuse, B is base and P is perpendicular
Area of triangle is given by :
Hence, the population density is .
Answer:
Step-by-step explanation:
2 3/4 ÷ 4 1/8
23/4×8/41
23×8/4×41
46/41
=1.122
So the answer is 1.122
The solution after divide 2 3/4 by 4 1/8 in fraction form is,
⇒ 2/3
We have to given that,
To divide 2 3/4 by 4 1/8.
Simplify it as,
2 3/4 ÷ 4 1/8
11/4 ÷ 33/8
11/4 x 8/33
(11 x 8) / (4x33)
2/3
Therefore, The solution after divide 2 3/4 by 4 1/8 in fraction form is,
⇒ 2/3
