In the diagram, BC⎯⎯⎯⎯⎯∥DE⎯⎯⎯⎯⎯ .

RUDIKE [14]

The length of AE is $18in$

Explanation:

From the figure, we can see that the two triangles ΔAED and ΔACB are similar. Thus, the legs of the triangle are proportional to each other.

Thus, we have,

$\frac{EC}{DB} =\frac{AE}{AD}$

Substituting the values of the sides from the image, we get,

$\frac{3}{1} =\frac{AE}{6}$

Multiplying both sides of the equation by 6, we get,

$6(3)=AE$

Multiplying, we have,

$18=AE$

Thus, the length of AE is $18in$

LuckyWell [14K]

Answer: A) 0.016

Step-by-step explanation:

The standard error is also known as the standard deviation of sampling distribution.

Formula : $S.E.=\sqrt{\dfrac{\overline{p}(1-\overline{p})}{n}}$

Given : The proportion of respondents approve the job that President Barack Obama was doing handling the economy : $\overline{p}=0.44$

Sample size : n= 1000

Then, the standard error (SE) of $\overline{p}$ is

$S.E.=\sqrt{\dfrac{0.44(1-0.44)}{1000}}\\\\=\sqrt{0.0002464}\\\\=0.0156971\approx0.016$

Hence, the standard error (SE) of $\overline{p}$ is 0.016 .

Estimate the product of<br> 5<br> and 4<br> Then find the product.

Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.
