<h2>The common denominator of $4\dfrac{6}{7}+7\dfrac{3}{14}$ = 7</h2>

Step-by-step explanation:

We have,

$4\dfrac{6}{7}+7\dfrac{3}{14}$

To find, the common denominator of $4\dfrac{6}{7}+7\dfrac{3}{14}$ = ?

∴ $4\dfrac{6}{7}+7\dfrac{3}{14}$

= $\dfrac{4\times 7 +6}{7} +\dfrac{7\times 14 +3}{7}$

$=\dfrac{34}{7} +\dfrac{101}{7}$

Taking the common as $\dfrac{1}{7}$ , we get

= $\dfrac{1}{7}$ $(34+101)$

The denominator = 7

∴ The common denominator of $4\dfrac{6}{7}+7\dfrac{3}{14}$ = 7

Hence, the common denominator of $4\dfrac{6}{7}+7\dfrac{3}{14}$ = 7

The SAT scores have an average of 1200 with a standard deviation of 60. A sample of 36 scores is selected. a) What is the probab

LiRa [457]

Answer:

a) 0.0082

b) 0.9987

c) 0.9192

d) 0.5000

e) 1

Step-by-step explanation:

The question is concerned with the mean of a sample.

From the central limit theorem we have the formula:

$z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$

a) $z=\frac{1224-1200}{\frac{60}{\sqrt{36} } }=2.40$

The area to the left of z=2.40 is 0.9918

The area to the right of z=2.40 is 1-0.9918=0.0082

$\therefore P(\bar X\:>\:1224)=0.0082$

b) $z=\frac{1230-1200}{\frac{60}{\sqrt{36} } }=3.00$

The area to the left of z=3.00 is 0.9987

$\therefore P(\bar X\:$

c) The z-value of 1200 is 0

The area to the left of 0 is 0.5

$z=\frac{1214-1200}{\frac{60}{\sqrt{36} } }=1.40$

The area to the left of z=1.40 is 0.9192

The probability that the sample mean is between 1200 and 1214 is

$P(1200\:$

d) From c) the probability that the sample mean will be greater than 1200 is 1-0.5000=0.5000

e) $z=\frac{73.46-1200}{\frac{60}{\sqrt{36} } }=-112.65$

The area to the left of z=-112.65 is 0.

The area to the right of z=-112.65 is 1-0=1

A translation is a transformation that slides each point of a figure the same distance in the same direction. The lines connecting each point of the preimage to its image are congruent. One type of transformation that is not an isometry is called a dilation<span>.</span>
