Answer:

75%

Step-by-step explanation:

What percent of 24 is 18?

24x = 18

x = 18/24 = 3/4 = 0.75 = 75% passed

A fair die is rolled in a board game to determine how many spaces a player can move on their turn. It has one of the numbers 1,2

Jet001 [13]

Answer:

(a)6 (b)3 (c)0.5

Step-by-step explanation:

Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.

Event A is the event of rolling an even number

Event B is the event of rolling an odd number.

(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}

There are 6 outcomes in the sample space.

n(S)=6

(b)

Event A is the event of rolling an even number

Sample space of A = {2,4,6}

There are 3 outcomes in event A.

n(A)=3

(c)The probability of event A

$P(A)=\dfrac{n(A)}{n(S)} =\dfrac{3}{6} =0.5$

P(A) =0.5 is the probability that you choose an even number.

Assume that f(x)=ln(1+x) is the given function and that Pn represents the nth Taylor Polynomial centered at x=0. Find the least

WINSTONCH [101]

Answer:

the least integer for n is 2

Step-by-step explanation:

We are given;

f(x) = ln(1+x)

centered at x=0

Pn(0.2)

Error < 0.01

We will use the format;

[[Max(f^(n+1) (c))]/(n + 1)!] × 0.2^(n+1) < 0.01

So;

f(x) = ln(1+x)

First derivative: f'(x) = 1/(x + 1) < 0! = 1

2nd derivative: f"(x) = -1/(x + 1)² < 1! = 1

3rd derivative: f"'(x) = 2/(x + 1)³ < 2! = 2

4th derivative: f""(x) = -6/(x + 1)⁴ < 3! = 6

This follows that;

Max|f^(n+1) (c)| < n!

Thus, error is;

(n!/(n + 1)!) × 0.2^(n + 1) < 0.01

This gives;

(1/(n + 1)) × 0.2^(n + 1) < 0.01

Let's try n = 1

(1/(1 + 1)) × 0.2^(1 + 1) = 0.02

This is greater than 0.01 and so it will not work.

Let's try n = 2

(1/(2 + 1)) × 0.2^(2 + 1) = 0.00267

This is less than 0.01.

So,the least integer for n is 2

Is y = 0 the asymptote of all functions of the form f(x) = ab^x? Explain your reasoning.

xeze [42]

Y=0 would be a horizontal line. An asymptote is a line that a function approaches, but never reaches. Exponential functions such as these are a smooth curve. If both numbers are positive numbers greater than or equal to 1, the curve increases. If at least one of the numbers is a positive number between 0 and 1, the curve decreases. If a is a negative number, the curve decreases as well. If either a or b is zero, then the graph would stay constant at 0. However, as long as neither a nor b is zero, then this graph will never touch that point. The only way to get an answer of y=0 is to multiply by 0. If neither a nor b is zero, this won't happen.

Line CD contains points A (4, -7) and B (4, 8). The slope of line CD is

mylen [45]

To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:

slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION

The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.
