Answer:
3 miles per hour
Step-by-step explanation:
he runs 1/3 mile in 1/9 of an hour
then
he runs (we multiply both sides by 9)
9×(1/3) mile in 9×(1/9) of an hour
then
he runs
(9/3) mile in (9/9) of an hour
then
he runs

Using an absolute-value inequality, describe the set of numbers whose distance from 4 is greater than 5 units. Draw a graph of this set on a number line. Finally, describe this set of numbers using inequalities without absolute value signs.
The solution to the absolute-value inequality is x > 9; and x < -1
What is an inequality?An inequality is an expression that shows the nonequal comparison of two or more numbers and variables.
Let x represent the unknown number, hence:
|x - 4| > 5
(x - 4) > 5; and -(x - 4) > 5
x > 9; and x < -1
The solution to the absolute-value inequality is x > 9; and x < -1

Answer:
Step-by-step explanation:
Finding the range is simple, just do 29-5 and you will get 24.
For the july one same applies 24-5=19
24-19 is 5 so It is 5 more than the range for July.
For the median, it is the middle data set meaning you will do 17-10 which is 7 meaning New years is 7 more than July.
Interquartile is For new years 12-17
The Interquartile range for July is 7-10 which means that is 5-3 which is 2 more of a range.
Use the series definition of sin to express sin (x4) as a power series centered at the origin. Explain why the power series converges for all real numbers.
Recall that
[tex]\sin(x) = \displaystyle \sum_{n=0}^\infty (-1)^n \frac{x^{2n+1}}{(2n+1)!}[/tex]
which converges for all real x. (One can show this with the ratio test, for instance.)
Then
[tex]\sin\left(x^4\right) = \displaystyle \sum_{n=0}^\infty (-1)^n \frac{\left(x^4\right)^{2n+1}}{(2n+1)!} = \boxed{\sum_{n=0}^\infty (-1)^n \frac{x^{8n+4}}{(2n+1)!}}[/tex]

If there are 20 lollipops and 40 candy bars for a gift bag, fill out all of the possible ratios of lollipops to candy bars that could be made
Answer:
20:40
Step-by-step explanation:
The required ratio of lollipops to candy bars is 1:2.
Given that,
There are 20 lollipops and 40 candy bars for a gift bag, fill out all of the possible ratios of lollipops to candy bars that could be made is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Total number of lollipops = 20, in a bag
Total number of candy bars = 40, in a bag
The ratio of lollipops to a candy bar in a bag,
Ratio = number of lollipops/number of candy bars
Ratio = 20 / 40
Ratio = 1 / 2
Ratio = 1:2
Thus, the required ratio of lollipops to candy bars is 1:2.

The graph of function g is created by applying these transformations to the parent tangent function:
• reflection over the x-axis
• horizontal stretch by a factor of 5
• vertical shift down 3 units
The transformed tangent function is:
g(x) = -5*tan(x) - 3
How to get the transformed function?We start with tangent function:
f(x) = tan(x).
First, we reflect our function over the x-axis, so we just have a change of sign as:
g(x) = -f(x).
Then, a horizontal stretch of scale factor of 5.
g(x) = -5*f(x)
Finally, a shift down of 3 units, this is:
g(x) = -5*f(x) - 3 = -5*tan(x) - 3
This is the transformed function.

Anna's mean or media
⇒ therefore we should calculate Carol's mean, median and Anna's
mean, median
Before we start calculating, let's define what is the mean and median
Mean: it is basically the average which is the sum of all numbers in the set divided by the number of numbers in that setMedian: it is the middle number of the set when the set is ordered from lowest to highestLet's calculate:
Carol's mean,median⇒ Carol's data ordered: 20, 30, 45, 60, 70
[tex]Mean = \frac{20+30+45+60+70}{5} = \frac{225}{5}=45\\ \\Median: 45[/tex]
Anna's mean, median⇒ Anna's data ordered: 30, 35, 45, 60, 65
[tex]Mean = \frac{30+ 35+ 45+ 60+ 65}{5} =\frac{235}{5} =47\\\\Median: 45\\[/tex]
Now using the data, let's compare:
first choice: Carol's mean is equal to her median--> correct
second choice: Carol's mean is not greater than Anna's mean--> incorrect
third choice: Anna's median isnot greater than her mean --> incorrect
fourth choice: Anna's mean is not equal to Carol's mean --> incorrect

a)729
b) 652
c) 693
d) 759
e) none of these
with explaination
Answer:
e) none of these
Step-by-step explanation:
35% of 242 would be 84.7%
We know this because we simply have to solve it!
We solve it by doing:
(35/100)*242
(35*242)/100
= 8470/100 = 84.7
We need to determine 35% of 242 now and the procedure explaining it as such
Step 1: In the given case Output Value is 242.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 242 = 100%.
Step 4: In the Same way, x = 35%.
Step 5: On dividing the pair of simple equations we got the equation as under
242 = 100% (1).
x = 35% (2).
(242%)/(x%) = 100/35
Step 6: Reciprocal of both the sides results in the following equation
x%/242% = 35/100
Step 7: Simplifying the above obtained equation further will tell what is 35% of 242
x = 84.7%
Therefore, 35% of 242 is 84.77

Dependent event is when two events are dependent events, one event influences the probability of another event whereas independent event has no effect on the probability of another event occurring.
↪DEPENDENT EVENT
When two events are dependent events, one event influences the probability of another event. A dependent event is an event that relies on another event to happen first. Dependent events in probability are no different from dependent events in real life. If you want to attend a concert, it might depend on whether you get overtime at work. if you want to visit family out of the country next month, it depends on whether or not you can get a passport in time. More formally, we say that when two events are dependent, the occurrence of one event influences the probability of another event.
Simple examples of dependent events
Robbing a bank and going to jail.Not paying your power bill on time and having your power cut off.Boarding a plane first and finding a good seat.Parking illegally and getting a parking ticket.↪INDEPENDENT EVENT
An independent event is an event that has no connection to another event’s chances of happening (or not happening). In other words, the event has no effect on the probability of another event occurring. Independent events in probability are no different from independent events in real life. Where you work has no effect on what color car you drive. Buying a lottery ticket has no effect on having a child with blue eyes.
When two events are independent, one event does not influence the probability of another event.
