The diagnonals of a parallelogram bisect each other ,

so

=》 BD = 3x × 2

=》BD = 6x

and there's given that

=》

BD = \dfrac{3}{5} AC

=》

6x =  \dfrac{3}{5}  \times 40

=》

x =  \dfrac{24}{6}

=》

x = 4

so, if x = 4 , then the given quadrilateral is a parallelogram.

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x
zimovet [89]

Answer:

y = 7x - 12

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m - > slope   & b -> y-intercept

y = 7x

So, slope = 7 & (2 , 2)

y - y1 = m(x -x1)

y - 2 = 7(x - 2)

y - 2 = 7x - 14

    y = 7x - 14 + 2

   y = 7x - 12

the standard deviation of the distribution of sample means (that is, the standard error, σm) is2.94 . (note: although µ and σ ar
pentagon [3]

Using the Central Limit Theorem, the standard error for the distribution of 559 restaurants is given by:

s = 0.0398.

<h3>What does the Central Limit Theorem state?</h3>


The Central Limit Theorem states that for a population with standard deviation \sigma and sample size n, the standard error is given by:

s = \frac{\sigma}{\sqrt{n}}

For this problem, the parameters are given as follows:

\sigma = 2.94, n = 559

Hence:

s = 2.94/sqrt(559) = 0.0398.

The standard error for the distribution of 559 restaurants is given by:

s = 0.0398.
