In politics, marketing, etc. We often want to estimate a percentage or proportion p. One calculation in statistical polling is t
inessss [21]

Answer: |p-72% |≤ 4%

Step-by-step explanation:

Let p be the population proportion.

The absolute inequality about p using an absolute value inequality.:

|p-\hat{p}| \leq E , where E = margin of error, \hat{p} = sample proportion

Given:  A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .

|p-72% |≤ 4%

⇒    72% - 4% ≤ p ≤ 72% +4%

⇒  68%  ≤ p ≤  76%.

i.e. p is most likely to be between 68% and 76% (.

Find the radius of a circle having area 616cm square.​
OLEGan [10]

Answer:

\boxed{\sf Radius \ of \ circle = 14 \ cm}

Given:

Area of circle = 616 cm²

To Find:

Radius of circle

Step-by-step explanation:

\sf \implies Area \ of \ circle = \pi r^{2}  \\  \\  \sf \implies 616 =  \frac{22}{7}  \times  {r}^{2}  \\  \\  \sf \implies 616 \times  \frac{7}{22}  =  {r}^{2}  \\  \\  \sf \implies 28 \times  \cancel{22} \times  \frac{7} { \cancel{22}}  =  {r}^{2}  \\  \\  \sf \implies 28 \times 7 =  {r}^{2}  \\  \\  \sf \implies 196 =  {r}^{2}  \\  \\  \sf \implies  {r}^{2}  = 196 \\  \\  \sf \implies r =  \sqrt{196}  \\  \\  \sf \implies r =  \sqrt{ {14}^{2} }  \\  \\  \sf \implies r = 14 \: cm
