Answer:

UCL (x bar) = 424

LCL (x bar) = 376

Step-by-step explanation:

Given:

Average calories contained, μ = 400

Standard deviation, σ = 30 calories

Sample size, n = 25

a) UCL (x bar) = $\mu+\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

UCL (x bar) = $400+\frac{4\times30}{\sqrt{25}}$

UCL (x bar) = 424

Similarly,

LCL (x bar) = $\mu-\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

LCL (x bar) = $400-\frac{4\times30}{\sqrt{25}}$

LCL (x bar) = 376

Part A Prove that when x > 1, a triangle with side lengths a = x2 − 1, b = 2x, and c = x2 + 1 is a right triangle. Use the Py

Nataly [62]

Step-by-step explanation:

Given : A triangle with side lengths $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

To find : Prove that when x > 1, it is a right triangle. Use the Pythagorean theorem and the given side lengths to create an equation. Use the equation to show that this triangle follows the rule describing right triangles. Explain your steps ?

Solution :

For right triangle the Pythagorean theorem is to be satisfied.

i.e. $c^2=a^2+b^2$

Here, $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

Substitute the values,

$(x^2+1)^2=(x^2-1)^2+(2x)^2$

$x^4+1+2x^2=x^4+1-2x^2+4x^2$

$x^4+1+2x^2=x^4+1+2x^2$

LHS=RHS

It is a right triangle.

Please help <br>cos40∘=sin(x+30∘)

iVinArrow [24]

Answer:

x = 20 degrees.

Step-by-step explanation:

cos40∘=sin(x+30∘)

sin (x + 30) = 0.766

x + 30 = arcsin 0.766 = 50

x = 50 - 30 = 20.
