Answer:

$3\frac{3}{8}$

Step-by-step explanation:

we have

$(10-6\frac{5}{8})$

we know that

$10=9+\frac{8}{8}=9\frac{8}{8}$

substitute

$(10-6\frac{5}{8})=9\frac{8}{8}-6\frac{5}{8}$

$=(9-6)\frac{8-5}{8}$

$=3\frac{3}{8}$

Answer:

cos P = 71.09

Step-by-step explanation:

cos = $\frac{adajcent}{hypotenuse}$

cos P = $\frac{24}{74}$

cos P = 0.324

cos-1 of 0.324 is 71.09

cos P = 71.09

For safety reasons, 4 different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills

Evgen [1.6K]

Answer:

<em>99.93%</em>

Step-by-step explanation:

<u>Probability of Independent Events</u>

Given the probability of success of each detector is 0.84 independently of the others, their combined success/failure probability can be computed with the product rule.

We can calculate the required probability by using the binomial distribution, but it's easier to calculate the probability of the negated event an subtract from 1.

We want to know the probability that a least one of the 4 systems detects the occurrence of theft. That probability is the sum of the probabilities that one of them, two of them, three of them or all of them succeed. The negated event is that NONE of them actually detects the theft. Being p the individual probability of success, p=0.84. Being q the probability of failure, q=0.16.

The probability that none of the systems detect the theft is

$P(0)=q^4=0.16^4=0.00065536$

Thus, the probability that at least one of the systems detect the theft is

$P(x\geq1)=1-P(0)=1-0.00065536=0.9993$

That means a 99.93%

How can you represent all of the solutions to systems of inequalities?

Dimas [21]

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

hope this helps have a great night ❤️❤️❤️
