Sati [7]

Answer:

$A=3.125\ cm^2$

Step-by-step explanation:

Given that,

The base of the parallelogram, b = 2.5 cm

Height of the parallelogram, h = 1.25 cm

We need to find the area of the logo. The formula for the area of the parallelogram is given by :

$A=b\times h\\\\A=2.5\times 1.25\\A=3.125\ cm^2$

So, the area of the logo is $3.125\ cm^2$ .

mixas84 [53]

Answer:

The approximate standard error of the sample proportion is $SE = 0.0454$

Step-by-step explanation:

From the question we are told that

The sample proportion is $\r p = 0.29$

The sample size is n = 100

Generally the standard error of the sample proportion is mathematically represented as

$SE = \sqrt{ \frac{ \r p (1- \r p )}{n} }$

substituting values

$SE = \sqrt{ \frac{ 0.29 (1- 0.29 )}{ 100 } }$

$SE = 0.0454$
