Can y’all please solve this

Answers

Answer 1

A). The answer is x = -4
Work:
3 - x = 11 + x
3 - x - 3 = 11 + x - 3
-x = x + 8
-x - x = x + 8 - x
-2x = 8
-2x/-2 = 8/-2
Answer: x = -4

B). The answer is x = 6
Work:
2x + 7 = 3x + 1
2x + 7 = 3x + 1 - 7
2x = 3x - 6
2x - 3x = 3x - 6 - 3x
-x = -6
-x/-1 = -6/-1
Answer x = 6

C). Answer: x = 4/3
Work:
8 - 2x = 4 + x
8 - 2x - 8 = 4 + x - 8
-2x = x - 4
-2x - x = x - 4 - x
-3x = -4
-3x/-3 = -4/-3
Answer: x = 4/3

D). Answer: x = 2
Work:
4x + 2 = 2x + 6
4x + 2 - 2 = 2x + 6 - 2
4x = 2x + 4
4x - 2x = 2x + 4 - 2x
2x = 4
2x/2 = 4/2
Answer: x = 2

Find the average rate of change between n=1 and n=3

Answers

Answer:

there is not enough information to solve

Step-by-step explanation:

You need two ordered pairs to calculate the average rate of change.

Let's say the value of the function at n = 1 is a, and the value of the function at n = 3 is b, then the average rate of change from n = 1 to n = 3 is

(b - a)/(3 - 1) = (b - a)/2

Determine whether each relation is a function. Explain. {(2,0), (2, 2), (2, 4), (2, 6)}

Answers

A function is the relationship between an independent variable (x) and a dependent variable (y). A function can only occur when the independent variable are limited to one use. A function in this case is determined by the { } symbol.

This example is not a function, as the independent variable (2) appears more than once.

The rule is that the independent variable(x) cannot appear more than once as the same value and the dependant variable(y) can appear more than once as the same value.

Unit 10: circles homework 2: central angles & arc measures

Answers

The central angle (127 degrees) is the angle at point K

The measures of JL and JML are 127 and 233 degrees, respectively

How to determine the measures of angles JL and JML?

From the complete question, we have:

JL = 127 degrees.

The sum of angles at a point is 360 degrees

So, we have:

JML + 127 = 360

Subtract 127 from both sides

JML = 233

Hence, the measures of JL and JML are 127 and 233 degrees, respectively

At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365-day year, what position in line gives you the best chance of being the first duplicate birthday?

please explain how you got this answer. Thank you!

Answers

The best chance is an illustration of probability

The 21st position in line gives you the best chance of being the first duplicate birthday

How to determine the best position?

Assume you are in the nth position, the probability of getting a free ticket is:

P(n) = P'(first n - 1 people share a birthday) * P(birthday with first n -1 people)

Mathematically, the above can be represented as:

P(n) = [365/365 * 364/365 * 363/365 * ... * (365 - (n -2))/365] * [(n -1)/365]

Such that: n [tex]\le[/tex] 365

When simplified, the equation becomes

p(n)/p(n+1) = 365/(366 - n) * (n - 1)/n

Where

p(n)/p(n+1) > 1

So, we have:

365/(366 - n) * (n - 1)/n > 1

Evaluate the product

(365n -365)/(366n - n²) > 1

Cross multiply

365n -365 > 366n - n²

Collect like terms

n² + 365n - 366n - 365 > 0

Evaluate the difference

n² - n - 365 > 0

Solve for n using a graphing calculator;

n > - 18.6 or n >19.6

n cannot be negative.

So, we have:

n > 19.6

Approximate to nearest integer

n > 20

The least integer value of n is:

n = 21

Hence, the 21st position in line gives you the best chance of being the first duplicate birthday

For each set of three lengths, determine if they can be the side lengths of a triangle.

Answers

Answer:

Yes, No, Yes, No

Step-by-step explanation:

Use the triangle inequality theorem, which states that the sum of any two side lengths must be greater than the third side length.

Apply this to each combination.

Use one inequality, compare the sum of smallest two sides with the largest side.

1) 4, 9, 8

4 + 8 = 12 > 9, so Yes

2) 7, 25, 7

7 + 7 = 14 < 25, so No

3) 8.8, 24, 15.8

8.8 + 15.8 = 24.6 > 24, so Yes

4) 5, 9, 3

3 + 5 = 8 < 9, so No

What is the maximum age of the youngest 25% of the passengers?

Answers

Using the percentile concept, it is found that the maximum age of the youngest 25% of the passengers is of 30.

What is the percentile concept?

When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.

Researching the problem on the internet, it is found that the distribution of the ages is described by a box and whisker plot, which states that:

The 25th percentile is of 30.The median is of 45.The 75th percentile is of 60.

Hence, the maximum age of the youngest 25% of the passengers is of 30.

A bicycle costs $240 and it loses 3/5 of its value each year.

A. Write expressions for the value of the bicycle,in dollars, after 1,2, and 3 years

B. When will the bike be worth less than $1?

Answers

Answer:

A. $96.00, $38.40, $15.36

B. after 6 years

Step-by-step explanation:

An exponential function has the general form ...

y = (initial value) × (growth factor)^t

The growth factor is 1 more than the growth rate. Here, the "growth" is actually a decay at the rate of 60% per year, so the growth rate is -0.60. The initial value is $240. The value equation can be written ...

y = 240(1 -0.60)^t

We want the value after t=1, t=2, and t=3 years.

y = $240(0.4)^1 = $96 . . . value after 1 year

y = $240(0.4)^2 = $38.40 . . . value after 2 years

y = $240(0.4)^3 = $15.36 . . . value after 3 years

We want to find t when y < 1.

240(0.4)^t < 1

0.4^t < 1/240 . . . . . . . . . . . . divide by 240

t × log(0.4) < log(1/240) . . . take logs

t > log(1/240)/log(0.4) . . . . . . . inequality reverses because log(0.4) < 0

t > 5.98

The bike will be worth less than $1 after about 6 years.

Answers

Answer: B

Step-by-step explanation:

These are vertical angles, so x+97=2x+32, meaning x=65.

So, the measure of angle 1 = 65 + 97 = 162 degrees

The value of m∠1, given that m∠1 = x + 97 and m∠2 = 2x + 32 is 162° (2nd option)

How to determine the value of m∠1?

First, we shall list out the given parameters from the question. This is given below:

m∠1 = (x + 97)° m∠2 = (2x + 32)°Angle 1 (m∠1 ) =?

Next, we shall obtain the value of x. Details below:

m∠1 = m∠2 (vertically opposite angle)

x + 97 = 2x + 32

Solving for x, we have:

97 - 32 = 2x - x

65 = x

Thus,

x = 65

Now, we shall obtain the value of m∠1 as follow:

m∠1 = x + 97

x = 65

Therefore,

m∠1 = 65 + 97

= 162°

Thus, the value of m∠1 is 162° (2nd option)
