identify each of the following as rational or irrational.

Answers

Answer:

Step-by-step explanation:

A rational number can be written as a fraction of two integers.

√23 is irrational because we do not know what the square root of 23 is in terms of integers in a fraction.

104.42 is rational because it can be expressed as 10442/100 . We can express it as this because

104.42 * 1 = 104.42 * 100/100 = 10442/100, and multiplying something by 1 keeps it the same

√64 is rational because it is equal to 8, and 8/1 is equal to 8

49.396 with the 6 repeating is rational because we can express 49.39 as

49.39 * 1 = 49.39 * 100/100 = 4939/100, and we are then left with

49.396- 49.39 = 0.006 (with the 6 repeating). A repeating decimal can be expressed as x/9, with the x representing all values before the repetition begins multiplied by 10.

For example, 0.6 with the 6 repeating can be represented as 6/9. This is because 0.6 * 10 = 6, and we divide that by 9. Similarly, 0.006 with the 6 repeating can be represented by 0.06/9

We add the two fractions together to get

4939/100 + 0.06/9

multiply both fractions by the other's denominator to even them out and make the numerator of the second fraction an integer

(4939*9)/(100*9) + (0.06*100)/(9*100)

= 44451/900 + 6/900

= 44460/900

Assuming that the last number has only the digits given, that is rational because, similarly to 104.42, it can be multiplied by a power of 10 to result in (integer)/(integer), making it rational. If the dots represent infinite digits, then it is not rational because there are infinite digits that are not repeating, and there is no way to know the last digit, so it is impossible to write a fraction from it

In Exercise 6, suppose that there is a probability of .01 that a digit is incorrectly sent over a communication channel (i.e., that a digit sent as a 1 is received as a 0, or a digit sent as a 0 is received as a 1). Consider a message that consists of exactly 60% 1s. a. What is the proportion of 1s received at the end of the channel

Answers

Answer:

The proportion of 1s received at the end of the channel is of 0.598.

Step-by-step explanation:

In this question:

60% of the bits sent are 1, 100 - 60 = 40% of the bits sent are 0.

For each bit receive, 0.01 probability of an error, so 0.99 probability it is correct.

a. What is the proportion of 1s received at the end of the channel?

99% of 60%(sent 1s, received 1).

1% of 40%(sent 0s, received 1). So

[tex]p = 0.99*0.6 + 0.01*0.4 = 0.598[/tex]

The proportion of 1s received at the end of the channel is of 0.598.

Step-by-step explanation:

(I'm assuming you need to find the missing side of the triangle)

To find missing values in a right angle. we will use the pythagoras theorem which states that:

h^2 = a^2 + b^2

16^2 = 14^2 + b^2

256 = 196 + b^2

256 - 196 = b^2

60 = b^2 (take sqaure root)

b= 7.75

Answer from Gauthmath

Answer:

7.75

Step-by-step explanation:

*I’m a big starter to brainly so I’ll appreciate if I can get brainliest please thank you*

Solve the right triangle is a incomplete question. Instead the correct question should’ve been: “Solve for the missing side length”.

Two things we need to understand for this

• Pythagorean theorem
• A, b and c sides
——————————————————————

Pythagorean theorem: a formula used to solve for a missing side length.

Pythagorean theorem = a^2 + b^2 = c^2 where a^2 would be 14 b^2 would be missing side and c^2 would be 16.

Makes sense cause the two sides added (a^2 & b^2) add up to c^2 which is the largest side.

Now we’re going to get right into the steps!

Step 1. Find the missing side length of the right triangle

a^2 + b^2 = c^2

Substitute the side lengths to the formula

14^2 + b^2 = 16^2

Simplify the exponents

196 + b^2 = 256

Solve for b^2

b^2 = 256 - 196

b^2 = 60

Note: that’s not the final answer that is just side b being squared now to undo the square we must square root 60.

Sqrt rt 60 = 7.75

So the missing side length of the triangle would be 7.75

Question 2.
If 0 is an angle in the first quadrant, and cos(θ) = 0.669, determine the value of
cos(π - θ), cos(π + θ), and cos(4π - θ) using Symmetry.

Answers

Answer:

1) -0.669

2) -0.669

3) 0.669

Step-by-step explanation:

Since we are subtracting or adding multipled of pi, we will either obtain 0.669 or -0.669 as our answer for each of the three different questions.

Cosine is the x-coordinate in our orderes pairs. If our point ends up on the right side of the y-axis, the cosine will be positive. If our point ends up on left side, it will be negative.

Choose a thetha (I'm going to choose it in degrees) in the first quadrant to help with a visual.

If theta=70:

1) then 180-70=110 which is in second quadrant, so our cosines will be opposite in value.

2) then 180+70=250 which is in third quadrant, so our cosines will be opposite in value.

3) then 4×180-70=720-70=650 =1(360)+290 which ends up in the 4th quadrant which means the consines will have the same value.

Answer:

O

Step-by-step explanation:

We can answer this by using the process of elimination

We want to find the position of 0.5

So let's begin

Looking at the number line...

D and E are both in between negative numbers

0.5 is not a negative number so immediately we can eliminate D and E

So it is between O and M

O is between 0 and 1

.5 is between 0 and 1 so O might be the answer

However let's look at M just to be safe.

M is located between 3 and 4.

Both 3 and 4 are greater than .5 meaning that M cannot represent .5

So we can conclude that O is the best answer

Answers

Slope is -2 and the y intercept is on the table where x is 0 so y intercept is 12
Answer:

The slope is -2, and the y-intercept is 12

Step-by-step explanation:

Slope = y2 - y1 / x2 - x1

Slope = 18 - 12/ -3 - 0

Slope = 6/-3

Slope = - 6/3

Slope = -2

So the slope is -2

When x was 0 y intercept was 12. Therefore, y-intercept = 12

y-intercept = 12

Step-by-step explanation:

Given that :

Number of cards in a standard deck = 52

Number of 3's in s standard deck = 4 (each suit has one card each)

Number of 8's in a standard deck = 4 (each suit has one card each)

Probability, P = required outcome / Total possible outcomes

Choosing without replacement :

P(top card is a 3) = 4 / 52

P(second draw is 8) = 4 / 51

P(top card is a 3 and second is 8) :.

4/52 * 4/51 = 16 / 2652 = 4 / 663
