Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

suppose that the lifetime of a transistor is a gamma random variable x with mean of 24 weeks and standard deviation of 12 weeks.
emmainna [20.7K]

The probability that the transistor will last between 12 and 24 weeks is 0.424

X= lifetime of the transistor in weeks E(X)= 24 weeks

O,= 12 weeks

The anticipated value, variance, and distribution of the random variable X were all provided to us. Finding the parameters alpha and beta is necessary before we can discover the solutions to the difficulties.

X~gamma(\alpha ,\beta)

E(X)= \alpha \beta                 \beta= 12^{2}/24=6 weeks

V(x)= \alpha \beta ^{2}                \alpha=24/6= 4

Now we can find the solutions:

The excel formula used to create Figure one is as follows:

=gammadist(X, \alpha, \beta, False)

P(12\leq X\leq 24)

P(12/6\leq G\leq 24/6)

P(2\leq G\leq 4)

P= 0.424

Therefore, probability that the transistor will last between 12 and 24 weeks is 0.424

Describe what is being done in each step while solving the equation -2x + 6 +6x = 6 ( 2x -3 )
Serggg [28]

-2x + 6 + 6x = 6 (2x - 3) <em>this is the equation</em>

-2x + 6 + 6x = 12x - 18 <em>distributive property has been applied</em>

4x + 6 = 12x - 18 <em>like terms have been added</em>

6 = 8x -18 <em>4x has been</em><em> </em><em>subtracted from both sides</em>

24 = 8x <em>-18 has been added to both sides</em>

3 = x <em>8 has been divided from both sides</em>

<em></em>

I hope this helps! Let me know if I need to explain more or if I got something wrong. Have a nice day!
