Ainat [17]3 years ago

Answer:

I think the answer is "Determine the shaded area for each line", because this is an example of an equation not an inequality. You can tell this is an equation because of the equal sign.

Inequalities are the problems in which you have to worry about shading, not equations. Inequalities can be identified by having either a greater than sign, a less than sign, a greater than-or-equal-to sign, or a less than-or-equal-to sign.

Example<br>2 (3x+11)=10​
Bumek [7]

Answer:

x = -2

Step-by-step explanation:

2 (3x+11)=10​

Divide each side by 2

2/2 (3x+11)=10​/2

3x+11 = 5

Subtract 11 from each side

3x+11-11 = 5-11

3x = -6

Divide each side by 3

3x/3 = -6/3

x = -2

In this problem we will be dealing with the probability density function (pdf) associated with a continuous random variable, X.
konstantin123 [22]

Answer:

b)\ 0.568

Step-by-step explanation:

Given

f(x) = 6x(1- x);\ 0 \le x \le 1

Required

P(0.3 < x < 0.7)

From the question, we have:

P(a < x < b) = \int\limits^b_a {f(x)} \, dx

So, we have:

P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x(1 - x)} \, dx

Open bracket

P(0.3 < x < 0.7) = \int\limits^{0.7}_{0.3} {6x - 6x^2} \, dx

Integrate

P(0.3 < x < 0.7) =  \frac{6x^2}{2} - \frac{6x^3}{3}}|\limits^{0.7}_{0.3}

P(0.3 < x < 0.7) =  3x^2 - 2x^3|\limits^{0.7}_{0.3}

Substitute 0.7 and 0.3 for x

P(0.3 < x < 0.7) =  (3*0.7^2 - 2*0.7^3) - (3*0.3^2 - 2*0.3^3)

Using a calculator, we have:

P(0.3 < x < 0.7) =  (0.784) - (0.216)

Remove brackets

P(0.3 < x < 0.7) =  0.784 - 0.216

P(0.3 < x < 0.7) =  0.568

The Sugar Sweet Company is going to transport its sugar to market. It will cost $4500 to rent trucks, and it will cost an additi
Elza [17]
C = 4500 + 150s

4500 is fixed, so what remains is just 150$ per ton of sugar (so 150 x s)

If we substitute 12 for s we get: 

C = 4500 + 150*12

C = 6300
