<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The tables show linear functions representing the estimated time it takes for the math and language arts portions of standardized tests with different numbers of questions.

The table is shown below.

The slope of math will be

Slope of math = (207 - 87)/ (65 - 25)

Slope of math = 120/40

Slope of math = 3

The slope of language arts will be

Slope of language arts = (248 - 88)/(60 - 20)

Slope of language arts = 160/40

Slope of language arts = 4

The language arts function has the greater slope, which shows that the estimated time per question for language arts is less than the estimated time per question for math.

Grace [21]

Answer:

calculate P(X=1) + P(X=2) +...+ P(X=12) using the binomial formula or an individual table in excel

calculate the P(X ≥ 12) using the binomial formula or a cumulative table in excel

Step-by-step explanation:

For a binomial distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

n = number of trials = 12 ; x = number of successes

p = probability of success = 0.2% = 0.002

1 - p = 1 - 0.002 = 0.998

Probability that atleast 1 is broken ;

p(1) + p(2) + p(3) +... + p(12) ;

This can be calculated by summing the values obtained using the binomial formula or in excel.

Alternatively, using the binomial formular or excel, the cumulative probability could be obtained as P(x ≥ 1)

A painting company will paint this wall of a building. The owner gives him the following dimensions.

Masja [62]

The given area of the $52\frac{1}{2}$ ft. by 33 ft. wall less the areas of the Windows and the Door give the area of the painted part of the wall as $\underline{1642\frac{9}{16}}$ ft.²

<h3>How can the area of the painted part be calculated?</h3>

The area of the painted part of the wall is $\underline{1642\frac{9}{16}}$ ft.²

The given dimensions of the wall are;

The width of the wall = $52\frac{1}{2}$ ft.

The height of the wall = 33 ft.

The painted area = Area of the wall - (Area of the widows + The door)

Which gives;

$52\frac{1}{2} \times 33 - \left(6\frac{1}{4} \times 5\frac{3}{4} + 3\frac{1}{8} \times 4 + 9\frac{1}{2} + 4 \times 8 \right) = \mathbf{ 1642 \frac{9}{16}}$

The area of the painted part of the wall is $\underline{1642\frac{9}{16}}$ ft.²
