Sorry I had to upload a question
2*8(16+12)=16*28
448 m^2
448/2=224
224*50= Rs 11,200
Answer:
The margin of error E that corresponds to a 95% confidence level is: 
Step-by-step explanation:
The propocion is 
The sample size 
95% confidence level
Level of significance = 1-level of confidence
Level of significance = 1-0.95 = 0.05
The formula for the error is:

The value for
according to the normal table
So:

2r-3.1=1.7 add 3.1
2r=1.7+3.1 divide by 2 to isolate r
2r/2=4.8/2
r=2.4
check
2(2.4)-3.1=1.7
4.8-3.1=1.7
1.7=1.7
4t+3.5=12.5 sub 3.5
4t=12.5-3.5 divide by 4
4t/4=9/4
t=9/4
check
4(9/4)+3.5=12.5
9+3.5=12.5
12.5=12.5
8m-5.5=10.1 add 5.5
8m=10.1+5.5 divide by 8
8m/8=15.6/8
m=1.95
check
8(1.95)-5.5=10.1
15.6-5.5=10.1
10.1=10.1
Answer:
x < -2
Step-by-step explanation:
1. Original Inequality: 10 – 2(2x + 2) > 14
2. 10-4x-4>14
<em>Distribute the -2 to 2x and 2. </em>
3. Simplify the left side: 6-4x>14
<em>Do 10-4 </em>
4. Subtract: -4x>8
<em>Subtract 6 from both sides to get x by itself</em>
5. Divide: x< -
<em>You want to divide by -4 that way you can find what x is. When you divide OR multiply by a negative number in an inequality you are going to need to switch the way the sign is facing.</em>
6. Simplify: x< -2
7. Check:
10-2(2(-3) +2) > 14
10-2(-6 + 2)
10-2(-4)
10+8
18 > 14
