How do i Evaluate In 7. ?

Mathematics
1 answer:
Pachacha [2.7K]2 years ago
3 0

Answer:

  (b)  1.95

Step-by-step explanation:

One of the easiest ways to evaluate an arithmetic expression of almost any kind is to type it into an on-line calculator. Many times, typing it into a search box is equivalent.

<h3>Application</h3>

See the attachment for the search box input (at top) and the result. This calculator has the benefit that it <em>always follows the Order of Operations</em> when evaluating an expression. (Not all calculators do.)

  ln(7) ≈ 1.95

__

<em>Additional comment</em>

If your math course is asking you to evaluate such expressions, you have probably been provided a calculator to use, or given the requirements for a calculator suitable for use in the course.

There are some very nice calculator apps for phone and tablet. Many phones and tablets already come with built-in calculator apps. For the purpose here, you need a "scientific" or "graphing" calculator. A 4-function calculator will not do.

As with any tool, it is always a good idea to read the manual for your calculator and work through any example problems.

__

Years ago, handheld calculators were not available, and most desktop calculators were only capable of the basic four arithmetic functions. Finding a logarithm required use of a table of logarithms. Such tables were published in mathematical handbooks, and extracts of those often appeared as appendices in math textbooks used in school.

Answer:

x = 5

Step-by-step explanation:

4x + 3 = 23 ( subtract 3 from both sides )

4x = 20 ( divide both sides by 4 )

x = 5

What is the volume of a cube, if the length of one side is 12 cm?
irinina [24]
The formula for the volume of a cube is length times width times height. Since the sides of a cube are all the same, it would be 12 cubed (12 x 12 x 12). The answer is 1,728 centimeters cubed.

For the following distribution,
Musya8 [376]

Answer:

Option B) 0.63

Step-by-step explanation:

We are given the following in the question:

X:            0          1           2            3

P(x):   0.027   0.189    0.441     0.343

We have to find the variance for the given discrete probability distribution.

E(X) = \displaystyle\sum x_iP(x_i)\\\\E(X) = 0(0.027) + 1(0.189) + 2(0.441) + 3(0.343)\\E(X) = 2.1\\\\E(X^2) = \displaystyle\sum x_i^2P(x_i)\\\\E(X^2) = 0^2(0.027) + 1^2(0.189) + 2^2(0.441) + 3^2(0.343)\\E(X^2) = 5.04\\\\Var(X) = E(X^2) -[E(X)]^2\\Var(X) = 5.04 - (2.1)^2\\Var(X) = 0.63

The variance of given distribution is 0.63

A. Using a protractor, draw a triangle that has two angles of 40°. Label all angle measures on your drawing and include your dra
PtichkaEL [24]

Answer:

Step-by-step explanation:

By terms of angle based conclusion triangle can be Obtuse angled triangle and by considering the sides as all angles are different It will be Scalene Triangle.

Step-by-step explanation:

Given:

Two angles of 40 degree

To Find :

How many triangles are possible Construct the triangle with given condition and Describe it.

Solution:

For Construction ,

Consider Triangle ABC with

∠A+∠B=40

So for 1st possibility as ∠A=10 then ∠B=30

2nd possibility as ∠A=20 then ∠B=20

3rd Possibility as ∠A=30 then ∠B =10

And angle c will remain the same for all three possibility i.e

Sum of all angles in triangle is 180

so angle c=140 degrees.

Hence there 3 Possibilities by which triangles can be made

So both angle A and B are acute angle since they measure less than 90 degree.

And angle C is Obtuse angle always

So angles in triangles are 2 acute and one Obtuse angle.

So One angle is Obtuse then triangle is Obtuse angled triangle

So triangle ABC is Obtuse angled triangle.

we can say that all three side will be different as all angles are different measures

So Triangle ABC is scalene triangle.

hope this helps =)
