Answer:
The width should be more than 5 m. So it can be 6,7 ...
Step-by-step explanation:
The length of a flower garden is = 9 m
The width of a flower garden is = w
The area of a flower garden > 45 sq. m
The area of a flower garden = l * b
l * b > 45
9 * b > 45
the width should be more than 5 m. So it can be 6,7 ...
Answer:
μ = 0.169
ME = 0.051
Step-by-step explanation:
The confidence interval is:
CI = μ ± ME
So the mean is the middle of the confidence interval, and the margin of error is half the difference.
μ = (0.118 + 0.220) / 2 = 0.169
ME = (0.220 − 0.118) / 2 = 0.051
Answer:
2
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplifying the radicals
= 
= 
× = 4
= 
= 
× = 2
Thus
+ 2 - 2
= 4 + 2 - 4 ← collect like terms
= 2

Of
Division
Multiplication
Addition and
Subtraction
go according to the BODMAS rule and solve the division first
24-(16÷4)×2+3
Then solve the multiplication part
24-(4×2)+3
Now solve like a regular sum
24-8+3
16+3
