Two companies, A and B, drill wells in a rural area. Company A charges a flat fee of 3681 dollars to drill a well regardless of

Answer:

Mean costing = $3,768

Step-by-step explanation:

Given:

Mean A(x) = 260

Rate = $10 per feet

Fixed charge = $1,168

Computation:

Assume;

depth = x ft

So,

Cost of company B = 10x + 1,168

So,

Mean costing = 10A(x) + 1,168

Mean costing = 10(260) + 1,168

Mean costing = 2,600 + 1,168

Mean costing = $3,768

A machine has four components, A, B, C, and D, set up in such a manner that all four parts must work for the machine to work pro

olchik [2.2K]

Answer:

0.756

Step-by-step explanation:

It is given that a machine has four components, A, B, C, and D.

$P(A)=P(B)=0.93, P(C)=0.95,P(D)=0.92$

If these components set up in such a manner that all four parts must work for the machine to work properly.

We need to find the probability that the machine works properly. It means we have to find the value of $P(A\cap B\cap C\cap D)$ .

If two events X and Y are independent, then

$P(X\cap Y)=P(X)\times P(Y)$

Assume the probability of one part working does not depend on the functionality of any of the other parts.

$P(A\cap B\cap C\cap D)=P(A)\times P(B)\times P(C)\times P(D)$

Substitute the given values.

$P(A\cap B\cap C\cap D)=0.93\times 0.93\times 0.95\times 0.92$

$P(A\cap B\cap C\cap D)=0.7559226$

$P(A\cap B\cap C\cap D)\approx 0.756$

Therefore, the probability that the machine works properly is 0.756.

Find the smallest solution to the equation 2/3 x^2=24

klio [65]

Ok so solve
2/3 times x^2=24
m ultply both sides by 3/2 to clear fraction
x^2=36
x=-6 or 6
-6<6
answer is x=-6 is smalles solution
