List the angles of triangle ABC in order from smallest to largest measure if AB=9, AC=11, and BC=10

nadezda [96]

The angles go in the same order as the sides across from them.
AB is the smallest side so angle C is across from it.
BC is the middle length so angle A is the middle angle. AC is the longest side so angle B is the largest angle.

Find the value of x and the measure of the angel labeled 6x. A. X=5; angle measure is 42 B. X=5; angel measure is 72 C. X= 5; an

Sergeu [11.5K]

Answer:

x = 5

angle measure labelled 6x is 30degrees

Step-by-step explanation:

Find the diagram attached

from the diagram;

6x = 30 (vertically opposite angle)

Divide both sides by 6

6x/6 = 30/6

x = 5

Get the angle labelled 6x

6x = 6(5)

6x = 30degrees

The lifetime of two light bulbs are modeled as independent and exponential random variables X and Y, with parameters lambda and

Scorpion4ik [409]

Answer:

$\bf h(x)=max(\lambda,\mu) e^{-max(\lambda,\mu) x}\;(x\geq0)$

Step-by-step explanation:

The PDF of X is

$\bf f(x)=\lambda e^{-\lambda x}\;(x\geq0)$

The PDF of Y is

$\bf g(x)=\mu e^{-\mu x}\;(x\geq0)$

The means of X and Y are respectively,

$\bf \displaystyle\frac{1}{\lambda}\;,\displaystyle\frac{1}{\mu}$

so we can see that the larger the parameter, the smaller the mean. Hence the PDF of Z = min(X, Y) is an exponential with the largest parameter of the two.

Therefore, the PDF of Z is

$\bf h(x)=max(\lambda,\mu) e^{-max(\lambda,\mu) x}\;(x\geq0)$

Find each product by distributing.<br> (2a - 5)(a? – 2a + 1)

Westkost [7]

Answer:

A = 1 , 1 , $\frac{5}{2}$

Step-by-step explanation:

Given equation as

(2a -5) (a² -2a +1) = 0

Or, (2a - 5) (a - 1 )² = 0

Or, (2a - 5) (a - 1) (a - 1) = 0

So, value of a are :

2a - 5 =0, a - 1 =0, a- 1 = 0

i.e a = $\frac{5}{2}$

and a = 1 , 1
