Answer:

201.1 mm²

Step-by-step explanation:

given that the diameter is 16mm,

radius = diameter ÷ 2 = 16÷2 = 8 mm

area of a circle is given by

A = πr², where

π=3.142

r = radius = 8 mm

Substituting these into the equation,

A = πr²

= 3.142 (8)²

= 201.088 mm²

= 201.1 mm² (rounded to nearest tenth)

Answer:

$MOE=\pm \ 1.41$

Step-by-step explanation:

-Given that $\sigma=1.91, n=7$

-We determine the z-value corresponding to the 95% confidence level:

$z_{\alpha/2}=z_{0.025}=1.96$

-The margin of error is the degree of error from the real value and is calculated as follows:

$MOE=\pm z_{\alpha/2} (\frac{\sigma}{\sqrt{n}})\\\\=\pm z_{0.025}\times\frac{\sigma}{\sqrt{n}}\\\\=\pm 1.96\times \frac{1.91}{\sqrt{7}}\\\\=\pm 1.41$

Hence, the margin of error is $\pm 1.41$

faltersainse [42]

Answer:

7 or -9, dependent on if 2y is or is not negative

Step-by-step explanation:

If 2y is NOT negative

2(4)-1=i

8-1=i

i=7

If 2y IS negative

-2(4)-1=i

-8-1=i

i=-9
