Answer:
the area of the glass is 1000cm^2
Step-by-step explanation:
Given that
The side is 50 cm
And, the power is 40 cm
We need to find out the area of the glass
So, the area of the glass is
= (50 × 40 ) ÷ 2
= 2,000 ÷ 2
= 1,000 cm^2
Hence, the area of the glass is 1000cm^2
The same is to be considered and relevant
Answer:
6x x 9= 54x
Step-by-step explanation:
product=multiplication so six the product of six and a number means to multiply and then multiply it by 9. to solve just multiply both numbers.
Answer:
C.I = 0.108 ± 0.022
Step-by-step explanation:
In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.
Therefore, the sample proportion will be:


= 0.108
p' = 0.108
To find the margin of error, we have:
M.E = ½ * length of confidence interval
Where length of confidence interval = 0.130 - 0.086
= 0.044
Therefore,

Margin of error = 0.022
The confidence interval is expressed as:
p' ± M.E
= 0.108 ± 0.022
Answer: D) 60x-45y = - 1 where A = 60 , B = -45 , and c = - 1
Step-by-step explanation: Clear it : 45y=60x+1
Step 2: Isolate the constant on one side: ( -1 = -45y +60x)
step 3: A= 60 , B= - 45 , C= - 1
