Okie doke. So, to find what 3/5 of the shape would be above, we should do 2/3 * 3/5. When you multiply straight across, you get 6/15 or 2/5 in simplest form. 2/5 of the original figure will be shaded after you erase 3/5 of the shaded part. The answer is 2/5.

2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.

At an ocean-side nuclear power plant, seawater is used as part of the cooling system. This raises the temperature of the water t
grandymaker [24]

Answer:

(a1) The probability that temperature increase will be less than 20°C is 0.667.

(a2) The probability that temperature increase will be between 20°C and 22°C is 0.133.

(b) The probability that at any point of time the temperature increase is potentially dangerous is 0.467.

(c) The expected value of the temperature increase is 17.5°C.

Step-by-step explanation:

Let <em>X</em> = temperature increase.

The random variable <em>X</em> follows a continuous Uniform distribution, distributed over the range [10°C, 25°C].

The probability density function of <em>X</em> is:

f(X)=\left \{ {{\frac{1}{25-10}=\frac{1}{15};\ x\in [10, 25]} \atop {0;\ otherwise}} \right.

(a1)

Compute the probability that temperature increase will be less than 20°C as follows:

P(X

Thus, the probability that temperature increase will be less than 20°C is 0.667.

(a2)

Compute the probability that temperature increase will be between 20°C and 22°C as follows:

P(20

Thus, the probability that temperature increase will be between 20°C and 22°C is 0.133.

(b)

Compute the probability that at any point of time the temperature increase is potentially dangerous as follows:

P(X>18)=\int\limits^{25}_{18}{\frac{1}{15}}\, dx\\=\frac{1}{15}\int\limits^{25}_{18}{dx}\,\\=\frac{1}{15}[x]^{25}_{18}=\frac{1}{15}[25-18]=\frac{7}{15}\\=0.467

Thus, the probability that at any point of time the temperature increase is potentially dangerous is 0.467.

(c)

Compute the expected value of the uniform random variable <em>X</em> as follows:

E(X)=\frac{1}{2}[10+25]=\frac{35}{2}=17.5

Thus, the expected value of the temperature increase is 17.5°C.

melomori [17]

It’s already in ascending order.

3/5= .6

5/8= .625

5/6= .833

7/4= 1.75

For what value of x is line m parallel to line n?   Enter your answer in the box. x =  ?
Zielflug [23.3K]

<u>Answer-</u>

<em>The value of x is </em><em>10</em>

<u>Solution-</u>

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

As m and n are parallel line, so

\Rightarrow 8x+50=130

\Rightarrow 8x=130-50

\Rightarrow 8x=80

\Rightarrow x=10
