Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in.

nadya68 [22]

Answer:

Step-by-step explanation:

Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.

We have to find values of x such that

$P(X\geq a) \leq 0.01\\$ and

$P(X\leq b) \leq 0.01$

a=2.33 and b =-2.33 as z values

Let us convert to X values

$x=22.1-2.33(1.2) \\x=22.1+2.33(1.2)\\$

i.e. values below 19.304 and above 25.496

Hence for x below 19.304 and above 25.496 are significantly low and high.

24.2 length is not significantly high.

A tree is broken at a height of 35 m from the ground and its top touches the ground at a distance of 12 m from the base of the t

sergij07 [2.7K]

Original height of tree = (x+5) m
In triangle ABC x square = 5 square + 12 square
X square = 25+144
X square = 169
X = 13
Thus the original height of the tree was 13+15 = 18m

the perimeter of the rectangular window glass is 26 dm. if the area is 36 sq dm, what are the dimensions of the window glass?

Anna007 [38]

The dimensions are 9x4. 9+4 adds up to 13, which is half of 26, or half of the perimeter, and 9x4 is equal to 36.

Solve the equation: <img src="https://tex.z-dn.net/?f=5%5Ex%5E%28%5Ex%5E-%5E1%5E%29%3D1" id="TexFormula1" title="5^x^(^x^-^1^)=1

Tomtit [17]

The concept:

We are given the equation:

$5^{x(x-1)} = 1$

Which can be simplified as:

$5^{x^{2} - x} = 1^{1}$

Since any number to the power '0' is 1

x² - x must be equal to 0 for the given equation to be true

Solving for x:

x² - x = 0

x(x-1) = 0

now, we can divide both sides by either x OR x-1

So we will see what we get for either choice:

x = 0/(x-1) x-1 = 0/x

x = 0 x = 1

Hence, the value of x is either 0 or 1
