Multiply 9/10 by 2/3:

9 * 2 3*1

--------- = --------- = 3/5 (answer)

10*3 5*1

Three fifths of the whole class has all-correct answers.

The surface of the water is 0 feet. So 10 feet down means it is 0 - 10, or -10 feet as its final position.

Which equation(s)

GalinKa [24]

Answer: A) y = 7x

<u>Step-by-step explanation:</u>

In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates

A) 0 = 7(0) ---> 0 = 0 TRUE

B) 0 = 2 + 3(0) ---> 0 = 2 False

C) 0 = Vz(0) ---> Too many variables so False

D) 0 = 5 - 0 ---> 0 = 5 False

Answer:

X=45

Step-by-step explanation:

You see the congruency markings use B.A.T to determine that the unmarked angle is x, therefore 4x=180 and x=45

The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to agi

fenix001 [56]

Answer:

Step-by-step explanation:

Given that

$\alpha =2.5$ , $\beta =220$

The weibull distribution with parameters $\alpha \ \ and \ \ \beta$

where $\alpha =0 \ \ , \beta =0$

$F(x,\alpha ,\beta) \left|\begin{array}{cc}\frac{\alpha }{\beta } x^{\alpha-1e^-(x/\beta)^\alpha &x\geq 0\\0&x$

Then,

$F(x,\alpha ,\beta )=\left|\begin{array}{cc}0&x$

A) The probability that a specimen's lifetime is at most 250 is

$P(X\leq 250)=F(250,2.7,220)\\\\=1-e^-^(250/220)^{2.7}\\\\=1-0.2436\\\\=0.7564$

The probability that the specimen's life time is more than 300 is

$P(X>300)=1-P(X\leq 300)\\\\=1-F(300;2.7,220)\\\\=1-(1-e^-^{(300/220)^{2.7}$

$=e^-^{(300/220)^{2.7}$

= 0.0992

b)The probability of the specimen's lifetime is between 100 and 250

$P(100$

c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is

$P(X>x)=0.50\\\\1-P(X$

x = 192.07
