Answer:

It is irrational, & cannot be written as a fraction.

Step-by-step explanation:

$\sqrt{2}$ will give you a very odd number when plugged into the calculator.

1.414213562

With our knowledge of rational vs. irrational numbers, we know that means $\sqrt{2}$ has to be irrational because it is not a whole number, not an integer, & cannot be condensed into a fraction.

Any time you see a number that isn't a perfect square in a square root, it might be best to guess it is irrational.

Always plug it into a calculator (if possible) to check!

Hope this helps. :)

Customers experiencing technical difficulty with their Internet cable hookup may call an 800 number for technical support. Itake

Paladinen [302]

Answer:

(A) The percent of the problems takes more than 5 minutes to resolve is 60.87%.

(B) The problem solving time will be 50% as long as the difference between the two end points is 5.75.

(C) a = 0.50 minutes, b = 12 minutes.

(D) Mean = 6.25 minutes, Standard deviation = 3.32 minutes

Step-by-step explanation:

Let the random variable X represent the time it takes the technician to resolve the problem.

The random variable X follows an Uniform distribution with parameters a = 0.50 minutes and b = 12 minutes.

The probability density function of X is:

$f_{X}(x)=\frac{1}{b-a};\ a$

(A)

Compute the probability that the problems takes more than 5 minutes to resolve as follows:

$P(X>5)=\int\limits^{12}_{5}{\frac{1}{12-0.50}}\, dx$

$=\frac{1}{11.50}\cdot \int\limits^{12}_{5}{1}\, dx \\\\=\frac{1}{11.50}\cdot [x]\limits^{12}_{5}\\\\=\frac{1}{11.50}\cdot [12-5]\\\\=\frac{7}{11.50}\\\\=0.608696\\\\\approx 0.6087$

Thus, the percent of the problems takes more than 5 minutes to resolve is 60.87%.

(B)

Let the middle 50% of the problem-solving times be between u and v.

Then,

P (u < X < v) = 0.50

$\int\limits^{v}_{u}{\frac{1}{12-0.50}}\, dx=0.50\\\\\frac{1}{11.50}\cdot \int\limits^{v}_{u}{1}\, dx=0.50\\\\\frac{v-u}{11.50}=0.50\\\\(v-u)=5.75$

Thus, the problem solving time will be 50% as long as the difference between the two end points is 5.75.

(C)

The interval in which the technician can solve the problem is 30 seconds to 12 minutes.

So, the values of a and b in minutes is:

a = 30 seconds = 0.50 minutes

b = 12 minutes.

(D)

The mean time is:

$\mu=\frac{a+b}{2}=\frac{0.50+12}{2}=6.25\ \text{minutes}$

The standard deviation of the time is:

$\sigma=\sqrt{\frac{(b-a)^{2}}{12}}=\sqrt{\frac{(12-0.50)^{2}}{12}}=3.3197\approx 3.32\ \text{minutes}$

which of these can be rewritten as an exact answer without the square root symbol? √4 √125 √0.6 √12.35 Thank you :)

Goshia [24]

Answer:

$\sqrt{4}$

Step-by-step explanation:

Because

→ $\sqrt{4}$ is equal to 2

→ $\sqrt{125}$ is equal to $5\sqrt{5}$ or 11.18033989

→ $\sqrt{0.6}$ is equal to $\frac{\sqrt{15} }{5}$ or 0.7745966692

→ $\sqrt{12.35}$ is equal to 3.514256678

What is the range of the graph? A) (3, 5) B) [3, 5] C) (2, 5) D) [2, 5]

vaieri [72.5K]

Answer:

B. [3, 5]

Step-by-step explanation:

The range of a graph are the y-values that are plotted on the vertical axis (y-axis). In order words, the range values, are the possible set of output values of that are plotted on the vertical axis on the graph.

"[ ]" is usually used to denote the possible set of values.

Therefore, the range of the given graph, as we can see from the y-axis, include values from 3 to 5. Therefore, the range of the graph is [3, 5].
