x = 2

Collect terms in x on one side of the equation and numeric values on the other

subtract 7x from both sides

1 + 4x - 7x = - 5

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 5 - 1 = - 6 ( divide both sides by - 3 )

x = $\frac{- 6}{- 3}$ = 2

1 + 4x = -5 + 7x

-4x - 4x

1 = -5 + 3x

+5 +5

6 = 3x

$\frac{6}{3} = \frac{3x}{3}$

2 = x

Answer: x = 2

The AAA system contains 3 independent components in parallel, each with probability of failure 0.4. Find the expected number of

Gre4nikov [31]

Answer:

Step-by-step explanation:

For each component, there are only two possible outcomes. Either it fails, or it does not. The components are independent. We want to know how many outcomes until r failures. The expected value is given by

$E = \frac{r}{p}$

In which r is the number of failures we want and p is the probability of a failure.

In this problem, we have that:

r = 1 because we want the first failed unit.

$p = 0.4[\tex]So[tex]E = \frac{r}{p} = \frac{1}{0.4} = 2.5$

The expected number of systems inspected until the first failed unit is 2.5

At Centertown Middle School, 25% of the 124 students Mrs. Wade teaches buy their lunches in the cafeteria.

cluponka [151]

Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.

Step-by-step explanation:

It is given that,

The 25% of 124 students are taught to buy their lunches in cafeteria.

Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.

To find the number of students who are capable to buy lunches in cafeteria:

Replace the % symbol into the numeric form.
The % is represented by 1 ÷ 100.

The 25% of 124 students is written as,

⇒ 25×(1/100)×124

⇒ (1/4)×124

⇒ 31

The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
