Answer:

y intercept = (0, ~-\frac{5}{2} )

x intercept = (-2, ~0)

.

Step-by-step explanation:

-5x - 5y = 10

.

y intercept

\to x = 0

-5(0) - 4y = 10

-4y = 10

y = \frac{10}{-4}

y = -\frac{5}{2}

so, the answer is (0, ~-\frac{5}{2} )

.

x intercept

\to y = 0

-5x - 4(0) = 10

-5x = 10

x = \frac{10}{-5}

x = -2

so, the answer is (-2, ~0)

.

Happy to help :)

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

Check all the answers to represent the same level of precision. A-0.59 B-100.6 C-98.42<br> D-1.045
sp2606 [1]
A) 0.59 uses 2 sig figs
B) 100.6 uses 4 sig figs (the zeros in this case are significant)
C) 98.42 uses 4 sig figs
D) 1.045 uses 4 sig figs (the zero is between other sig figs so it's significant)

Every choice but choice A has 4 sig figs. So the answers are B, C, and D
