Answer: The value of 'n' is 6.

Step-by-step explanation:  Given that ΔXWZ is an isosceles triangle, where XZ = n, WZ = 2n - 5, and the perimeter of the triangle is 20 units.

We are to find the value of 'n'.

As given in the figure, in ΔXWZ,

WX = WZ.

So, WX = 2n - 5.

We know that the perimeter of a triangle is equal to the sum of its three sides, so the perimeter of ΔXWZ is given by

P=XZ+WX+WZ=n+(2n-5)+(2n-5)=5n-10.

According to the question, we have

P=20\\\\\Rightarrow 5n-10=20\\\\\Rightarrow 5n=30\\\\\Rightarrow n = 6.

Thus, the value of 'n' is 6.

ABC ~ ADE AC = 4, AE = 7, AD = 10, what is the length of AB? 1 3/7 2 1/2 5 5/7 17 1/2
Butoxors [25]

If the polygon or the figures are similar then it is known that the ratios of their corresponding sides and angles are proportional. In this item we can derive an equation that is,

<span>                        AC/AE = AD/AB</span>

Substituting the known values,

<span>                      4/7 = 10/AB</span>

<span>AB from the equation is equal to 70/4 or equal to 17 ½. </span>

Which of the following is a solution of y - x &lt; -3?<br><br> (6, 2)<br> (2, 6)<br> (2, -1)
Snowcat [4.5K]
Personally I'd solve this inequality for y first:  y < x-3.

That immediately eliminates (6,2) and (2,6).

Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?

-1 < 2 -3     NO.  -1 < -1 is false.  Was there a fourth answer choice?

The R.D. Wilson Company makes a soft drink dispensing machine that allows customers to get soft drinks from the machine in a cup
Vanyuwa [196]

Answer:

B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.

Step-by-step explanation:

to calculate mean

14.25+ 13.7 +14.02 +14.13+ 13.99 +14.04

= 84.13/6

= 14.02167

average = 14

s = 0.1837

test statistics t:

(bar(x)-mu)/(s/√n)

= 14.02167-14/0.1837/√6

0.02167/0.1837/2.4495

= 0.02167/0.07499

=0.28897

this is approximately 0.29

<u>therefore B) The null hypothesis cannot be rejected since the test statistic is approximately t = .29,which is not in the rejection region.</u>
