sertanlavr [38]

(Y/4) +3 = 7

Subtract 3 from both sides:

Y/4 = 4

Multiply both sides by 4

Y = 16

What is the value of x pls HELP!!!!!
vovangra [49]

Answer:

70

Step-by-step explanation:

The angle is equal to the degree of the arc, so the angle, 2x, is equal to 140°.

140 = 2x

140/2 = x

70 = x

x is equal to 70.

For which rational expression is –5 an excluded value of x?<br>x-5/6<br>x+5/6<br>6/x-5<br>6/x+5
Ira Lisetskai [31]

For 6/x+5  –5 is an excluded value of x.

So, Option D is correct answer.

Step-by-step explanation:

We need to find for which rational expression is –5 an excluded value of x.

A value of x is excluded in a rational expression if it makes the denominator of that expression equal to zero and makes the expression undefined.

In the options given below, if we put x= -5 the only option D will become undefined i.e

\frac{6}{x+5}\\Put\,\,x=-5\\=\frac{6}{-5+5}\\=\frac{6}{0}

As we know 6/0 = undefined so, for 6/x+5  –5 is an excluded value of x.

So, Option D is correct answer.

Use the set of data to calculate the measures that follow.
zepelin [54]

Answer:

<h3>Mean=3.5</h3><h3>Median=3.5</h3><h3>Range=6</h3><h3>Interquartile=1</h3>

Step-by-step explanation:

Given set of data is 0, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 6

<h3>To find Mean , Median , Range and Interquartile range :</h3>

First finding Mean

  • Mean=\frac{sum of the observations}{number of observations}
  • =\frac{0+2+3+3+3+3+3+4+4+4+4+5+5+6}{14}
  • =\frac{49}{14}
  • =\frac{7}{2}
  • =3.5
<h3>Therefore Mean=3.5</h3><h3>Median:</h3>
  • Since the number of observations is even, so the meadian becomes
  • Median=\frac{sum of the two mid terms}{2}
  • =\frac{3+4}{2}
  • =\frac{7}{2}
  • =3.5
<h3>Therefore Median=3.5</h3><h3>Range:</h3>
  • Range=greatest value-least value
  • In the given observations we have greatest value is 6 and least value is 0
  • Therefore Range=6-0
<h3>Therefore Range=6</h3><h3>Interquartile:</h3>
  • From the observations we have Q_1=3 and Q_3=4
  • Interquartile=Q_3-Q_1
  • =4-3
<h3>Therefore Interquartile=1</h3><h3 />
