Surface area = 90 cm²

Step-by-step explanation:

Given net of the rectangular prism shows the dimensions as,

Length = 5 cm

Width = 5 cm

Height = 2 cm

`Expression for the surface area of a rectangular prism = 2(lb + bh + hl)

Here, l = length

w = width

h = height

By substituting the values in the expression,

Surface area = 2(5×2 + 5×2 + 5×5)

                      = 2(10 + 10 + 25)

                      = 90 cm²

Answer:

0.013 = 1.3% probability that fifteen employees must be tested in order to find three positives.

Step-by-step explanation:

For each employee, there are only two possible outcomes. Either they test positive, or they do not. The probability of an employee testing positive is independent of any other employee, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

40% of the employees have positive indications of asbestos in their lungs

This means that [tex]p = 0.4[/tex]

Find the probability that fifteen employees must be tested in order to find three positives.

2 during the first 14(given by P(X = 2) when n = 14).

The 15th is positive, with 0.4 probability. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{14,2}.(0.4)^{2}.(0.6)^{12} = 0.0317[/tex]

0.0317*0.4 = 0.013.

0.013 = 1.3% probability that fifteen employees must be tested in order to find three positives.

Answer:

[tex](f\cdot g)(x) = 2x^3 + 5x^2-x-6[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=2x^2+x-3\text{ and } g(x)=x+2[/tex]

And we want to find:

[tex](f \cdot g)(x)[/tex]

Recall that this is equivalent to:

[tex]=f(x)\cdot g(x)[/tex]

Substitute. Hence:

[tex](f\cdot g)(x)= (2x^2+x-3)(x+2)[/tex]

Expand if desired:

[tex]\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6[/tex]

Answer:

2x^3+5x^2-x-6

Step-by-step explanation:

f(x) = 2x^2 + x − 3 and g(x) = x + 2.

(f • g)(x) = (2x^2 + x − 3 ) * (x + 2)

Distribute

           =  (2x^2 + x − 3 )*x + (2x^2 + x − 3 )*2

            = 2x^3 +x^2 -3x + 4x^2 +2x -6

Combine like terms

            =2x^3+5x^2-x-6

The distance AB across the river is approximately 171.4 meters

The known parameters are;

The distance BC laid off on one side of the river = 415 m

The measure of ∠B = 112.2°

The measure of angle ∠C = 18.3°

The unknown parameter;

The distance AB across the river

Strategy;

Taking the points A, B, and C, being the vertices of the triangle, ΔABC, and apply sine rule to find distance AB;

By the angle sum property, the measure of angle, ∠A = 180° - (∠B + ∠C)

∴ ∠A = 180° - (112.2° + 18.3°) = 49.5°

By sine rule, we get;

[tex]\mathbf{\dfrac{a}{sin (\alpha)} = \dfrac{b}{sin (\beta)} = \dfrac{c}{sin (\gamma)}}[/tex]

Therefore;

[tex]\mathbf {a = sin (\alpha) \times \dfrac{b}{sin (\beta)}}[/tex]

Plugging in α = AB, [tex]\alpha[/tex] = ∠C = 18.3°, b = BC = 415, β = ∠A = 49.5°, we get;

[tex]AB = sin (18.3 ^{\circ}) \times \dfrac{415}{sin (49.5^{\circ})} \approx 171.4[/tex]

The distance across the river, AB ≈ 171.4 m

Answer:

The approximate percentage of cars that remain in service between 36 and 39 months is of 2.35%.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 45 months, standard deviation of 3 months.

What is the approximate percentage of cars that remain in service between 36 and 39 months?

36 = 45 - 3(3)

39 = 45 - 2(3)

So within 2 and 3 standard deviations below the mean.

99.7 - 95 = 4.7% of the measures are between 2 and 3 standard deviations of the mean, however, this is two-tailed, considering both above and below the mean.

In this case, both 36 and 39 are below the mean, and due to the symmetry of the normal distribution, this percentage is divided by half, so 4.7/2 = 2.35.

The approximate percentage of cars that remain in service between 36 and 39 months is of 2.35%.

Answer:

y - 1 = 4x - 20.

The slope of the line y = 4x +1 is the coefficient of x, so the slope is 4. Parallel lines have the same slope, so the slope of the "other" line is also 4. Using the point-slope form of a line, the equation of the line in question is: y - 1 = 4(x - 5). Distributing 4, we get y - 1 = 4x - 20. i dont know correct me if im wrong

Answer:

Dado que el área de un triángulo es igual a la multiplicación de su base por su altura, si la base de un triángulo se duplica, su área se incrementará, con lo cual la afirmación es incorrecta, ya que el área no se reducirá a la mitad. Así, por ejemplo, un triángulo de base 10 y altura 15 tendrá un área de 50 (10 x 5), mientras que si su base se duplica a 20, pasará a tener un área de 100 (20 x 5), con lo cual su área también se duplicará.

Answer:

A. 9

Step-by-step explanation:

First find the slope (m) using two given pairs of values form the table, say (1, 6) and (2, 3):

Slope (m) = change in y/change in x

Slope (m) = (3 - 6)/(2 - 1) = -3/1

Slope (m) = -3

Next, substitute (1, 6) = (x, y) and m = -3 into y = mx + b and solve for y-intercept (b).

Thus:

6 = -3(1) + b

6 = -3 + b

Add 3 to both sides

6 + 3 = -3 + b + 3

9 = b

b = 9

y-intercept = 9
