1. (1.35)x(.42)
1.35
x. .42
________
270
5400
________
.5670
You need to have the total number of decimal places from the original two numbers. 1.35 has two decimal places and .42 has to decimal places you have a total of four decimal places, Which means 5670 is .5670
2. (.22)x(.04)
.22
x. .04
_______
88
00
_______
.0088
you need to have the total number of decimal places from the original Two numbers. So .22 is two decimal places and .04 is two decimal places, so you will need to have for decimal places. That means that the answer 88 needs to be translated into .0088
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
An outlier causes the range of the population to move slightly towards the outlier.
Hi
The answer is : 14s^133t^5u^144v^2
Good luck :) You can trust my answer
Lets x = width
height = 2x - 4
A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7
so width = 9
height = 2(9) - 4 = 18 - 4 = 14
answer
width = 9 in
height = 14 in
