Jamie has applied for a credit card. The APR of the card is 20%. What will be the monthly interest rate?
Answer:
1.67%
Step-by-step explanation:
The APR of a card is the Annual Percentage Rate. This is the yearly rate of interest that a person has to pay on the money he or she borrowed. Interest is a price that is paid for borrowing money. In this case, if the APR is 20%, we would need to divide this number by the number of months in a year in order to get the monthly interest rate:
20 / 12 = 1.67 %

What is the letter ƒ in mathematics?
The letter f usually indicates that the equation is a function in the notation f(x).
Example: f(x) = x + 1
It is a fancier/more proper replacement for the variable 'y'. The same is used for the letter g as in g(x) and h as in h(x).
OR
It could just be a regular ole variable
Example: f + 1 = 7, solve for f
Suppose that e and f are events in a sample space and p(e) = 2/3, p(f) = 3/4, and p(f |
e.= 5/8. find p(e | f).
A video posted on the internet is becoming very popular,and the total number of views is increasing by 40% every hour if the video currently has 38,000 views how many views will it have in 2 hours
Final answer:
The video with an initial 38,000 views will have approximately 74,480 views in 2 hours when it is increasing by 40% every hour.
Explanation:
To calculate the number of views a video will have in 2 hours if it is increasing by 40% every hour, we will use the formula for percentage growth. Initially, the video has 38,000 views. After one hour, the views will be increased by 40%, and after two hours, this new amount will again be increased by 40%. The formula for calculating the number of views after each hour is:
Views after n hours = Initial views × [tex](1 + growth rate)^n[/tex]
Where:
Initial views = 38,000
Growth rate = 40% = 0.40 (as a decimal)
n = number of hours
After 1 hour:
Views after 1 hour = 38,000 × (1 + 0.40)^1
Views after 1 hour = 38,000 × 1.40 = 53,200
After the second hour, we will use the number of views from the first hour to calculate the increase:
Views after 2 hours = 53,200 × [tex](1 + 0.40)^1[/tex]
Views after 2 hours = 53,200 × 1.40 = 74,480
Therefore, the video will have approximately 74,480 views in 2 hours.
For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. the 50 paired ratings yield x overbarxequals=6.46.4, y overbaryequals=6.06.0, requals=negative 0.281−0.281, p-valueequals=0.0480.048, and modifyingabove y with caretyequals=8.128.12negative 0.323−0.323x. find the best predicted value of modifyingabove y with carety (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is xequals=55. use a 0.100.10 significance level.
To find the best predicted value of female attractiveness rating for a male rating of 5, substitute '5' for 'x' in the given regression equation, then calculate the result.
Explanation:In your given problem you have mentioned a linear regression equation, modifyingabove y with caretyequals=8.128.12negative 0.323−0.323x, that was derived from paired attractiveness ratings of males and females from 50 speed dates. The male attractiveness rating is your independent variable x and the female attractiveness rating is your dependent variable y.
You are asked to calculate the predicted female attractiveness rating if a male rates a female as 5 (x equals 5). To do this, you need to substitute x with 5 in the regression equation, which leads to the following calculation:
modifyingabove y with caret = 8.12 - 0.323 * 5.
By calculating this equation, you get the best predicted value of modifyingabove y with caret (attractiveness rating by female of male).

Looking at the ping-pong ball toss board below, whats the probability of landing on a gray square? (Note the board contains 5 rows of 5 squares.)
Answer:
Option D. [tex]\frac{1}{5}[/tex] is the correct option.
Step-by-step explanation:
Total number of solution sets n(S) (sample space) = 5×5 = 25
(Since a ping-pong ball can land on any block of the toss board so total number of events which can occur will be = 25)
Now preferred events n(E) = 5
(Since number of grey squares where ping-pong ball can land are = 5)
Therefore probability of landing of ping pong ball on a grey square P(E) = [tex]\frac{n(E)}{n(S)}[/tex]
P(E) = [tex]\frac{5}{25}[/tex]
P(E) = [tex]\frac{1}{5}[/tex]
Therefore, Option D. [tex]\frac{1}{5}[/tex] will be the answer.

5-2i and 7+6i find the midpoint
The midpoint between the complex numbers 5-2i and 7+6i is 6 + 2i.
Explanation:To find the midpoint between two complex numbers, we can use the formula:
Midpoint = (Re(z1) + Re(z2))/2 + (Im(z1) + Im(z2))/2i
Applying the formula to the given complex numbers 5-2i and 7+6i, we have:
Midpoint = (5 + 7)/2 + (-2 + 6)/2i
Midpoint = 12/2 + 4/2i
Midpoint = 6 + 2i

The current size of an image on Samuel's computer is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 8 inches and the width is labeled as width equal to 10 inches. What are the dimensions of the image at fraction 1 over 2 times its current size
Answer:
The length and the width of image is 4 inches and 5 inches respectively
Step-by-step explanation:
Given : Length of rectangle is 8 inches
Width of rectangle is 10 inches
To Find: What are the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
Solution:
Length of rectangle is 8 inches
Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
So, Length of image = [tex]\frac{1}{2} \times 8 = 4[/tex]
Thus the length of image is 4 inches.
Width of rectangle is 10 inches
Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
So, width of image = [tex]\frac{1}{2} \times 10 = 5[/tex]
Thus the width of image is 5 inches.
Hence the length and the width of image is 4 inches and 5 inches respectively.

If a function is always positive, then what must be true about its derivative? (a) the derivative is increasing (b) the derivative is decreasing (c) the derivative is always positive (d) the derivative is never negative (e) you can't conclude anything about the derivative
Though a function is always positive, it doesn't provide specific information about its derivative. The derivative can be positive, negative, or zero, depending on whether the function is increasing, decreasing, or constant. Hence, we can't definitively conclude anything about the derivative if we only know the function is always positive.
Explanation:If a function is always positive, it means that its graph lies entirely above the x-axis. However, this fact provides no definitive information about the derivative of the function.
The derivative of a function tells us the rate at which the function is changing. It can be positive, negative, or zero, depending on whether the function is increasing, decreasing, or constant, respectively. However, for a function to be always positive, does not necessarily dictate whether it is constantly increasing, decreasing, or constant.
For instance, consider the function y = x2. This function is always positive for x ≥ 0, but its derivative, which is 2x, is not always positive. It is zero when x = 0 and positive for x > 0. Similarly, think of an undulating curve-like sine function which stays above the x-axis. Its derivative oscillates between positive and negative as the function goes through its crest and trough points.
Therefore, the answer to your question is (e) you can't conclude anything about the derivative just because the function is positive.
