Find the length of the other two side of the isosceles right triangle

Valentin [98]

Answer:

The other two sides are 7 units each.

Step-by-step explanation:

The triangle is isosceles.

The sides are in the ratio of

$x : x : x \sqrt{2}$

The hypotenuse is

$7\sqrt{2}=x \sqrt{2}\\\\x = 7$

So, the other two sides are 7 units each.

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distribute

bulgar [2K]

Answer:

The area of the shaded region is 0.2898.

Step-by-step explanation:

Let <em>X</em> represent the IQ scores of adults.

It is provided that $X\sim N(100,15^{2})$ .

Compute the probability of an adult having an IQ between 106 and 124 as follows:

$P(106$

$=P(0.40$

*Use a <em>z</em>-table.

Thus, the area of the shaded region is 0.2898.

what is the sum of the first five ferms of a geometric series with a1=10 and r=1/5? express your answer as an important fraction

mote1985 [20]

The sum of any geometric sequence, (technically any finite set is a sequence, series are infinite) can be expressed as:

s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=term number

Here you are given a=10 and r=1/5 so your equation is:

s(n)=10(1-(1/5)^n)/(1-1/5) let's simplify this a bit:

s(n)=10(1-(1/5)^n)/(4/5)

s(n)=12.5(1-(1/5)^n) so the sum of the first 5 terms is:

s(5)=12.5(1-(1/5)^5)

s(5)=12.496

as an improper fraction:

(125/10)(3124/3125)

390500/31240

1775/142
