The probability that both I and my best friend get the 100 classroom credits is 0.06%.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Since Mr Q's class is having a give-away where his students can receive 100 classroom credits, he will pull names out of a hat and select two winners, and once a student wins, they are not eligible to win a second time, if there are 40 total people in the class, including me and my best friend, to determine what is the probability that both I and my best friend get the 100 classroom credits, the following calculation must be performed:
I = 1/40 = 0.025
my best friend = 1/39 = 0.02564
0.02564 x 0.025 = X
0.0006410 = X
X x 100 = 0.064
Therefore, the probability that both I and my best friends get the 100 classroom credits is 0.06%.

What is the product of 0 and any number?
Answer:
It will always be 0 because the rule is anything times 0 is 0
Answer:
0
Step-by-step explanation:
Hey there!
The product of any number and 0 is zero
To explain why this is, just think of it visually
So lets say we are visually explaining 7 x 3
Here is a visual explanation
There are 7 strawberries
You take 7 more strawberries
You take 7 more strawberries again
This means that you are taking 7 strawberries 3 times thereby forming the equation, 7 x 3
Now lets say a numeber [tex]x[/tex] times zero is equal to what
Well we can visualize this again
There are [tex]x[/tex] strawberries in a group
You are taking zero of those groups
Meaning there are no groups
So if there are no groups
There are no strawberries
Meaning [tex]x[/tex] times zero is zero
Since [tex]x[/tex] is any number, the statement, the product of 0 and any number is 0 is true
This is why the product of 0 and any number is 0

Mrs. norris is assigning the line up of the trumpet players in the parade. tell whether the events are dependent or independent. explain your answer.
event a: kadonna is chosen to be the first trumpet player in line
event b: jerome is chosen to be the second trumpet player in line
a: the choice of the first trumpeter does not affect the choice of the second, so the events are independent.
b: the choice of the first trumpeter does not affect the choice of the second, so the events are dependent.
c: the person chosen to be first cannot also be second, so the events are independent.
d: the person chosen to be first cannot also be second, so the events are dependent
The event A is an independent event while the event B is a dependent event.
How to find dependent or independent events?
An independent event is one that is not affected by the occurrence of other events while a dependent event is one that is affected by the occurrence of another event.
Event A is an independent event because the first player does not have to wait for any player before he plays.
However, event B is a dependent event as Jerome has to wait for for the first player to play before he can play.

Answer:
1.7.
Step-by-step explanation:
2x^3 + 9x^2 - 2x + 8 = 40
Substituting values for x in the range 1 to 2:
when x = (1.1):
f(1.1) = 2(1.1)^3 + 9(1.1)^2 - 2(1.1) + 8 = 19.32.
x = 1.3:
f(1.3) = 25.004
F(1.5) = 32
F(1.6) = 36.032
F(1.7) = 40.436 which is just greater than 40.
So the root is between 1.6 and 1.7.
f(1.65) = 38.19
Therefore the root is > 1.65 and < 1.7
and to 1 DP it is 1.7.

What is the divisible rule of 9 and 5?The divisible rule of 9 and 5 are:
Divisible rule of 9- When the addition of all number is divisible by 9, then that number also divisible by 9.Divisible rule of 5- When a number has a digit 0 or 5 in the last of it, then that number also divisible by 5.Two digits of the 6-digit number are missing.
[tex]X = 345 * 8*[/tex]
The smallest possible number from this is divisible by 45. The factors of 45 are 9 and 5.
[tex]45=9\times5[/tex]
Thus, the 6-digit number which is divisible by 45, must be divisible by 9 and 5.
To be divisible with 5, the number has 0 or 5 in last. So the numbers can be,
[tex]X = 345 * 85\\X=345 * 80[/tex]
For first number, when the blank is filled with number 2 to make sum 9 and for second the blank number should be 7. Thus, the numbers,

The distance from B to B is 5.
This is because the distance between the original and new coordinates would remain the same. This is because it is done by translation and not because of the rotation. The distance between the two will still remain as 5.
Zendaya has $700 to spend at a bicycle store for some new gear and biking outfits. assume all prices listed include tax. she buys a new bicycle for $242.33. she buys 3 bicycle reflectors for $7.17 each and a pair of bike gloves for $33.68. she plans to spend some or all of the money she has left to buy new biking outfits for $77.40 each. write and solve an inequality which can be used to determine xx, the number of outfits zendaya can purchase while staying within her budget.
Answer:
she could buy 5 outfits
Step-by-step explanation:
you multiply 7.17 by 3 = 21.51
700 - 21.51 = 678.49
678.49 - 242.33 = 436.16
436.16 - 33.68 = 402.48
402.48 divided by 77.40 = 5
The function is defined over the interval [2, 5]. if the interval is divided into equal parts, what is the value of the function at the right endpoint of the th rectangle?
The value of the function at the right endpoint of the rectangle is 5 +6k/n.
What is the endpoint about?In the question above;
Th width of the interval is said to be (5 -2) = 3.
So, the width of one of n parts of it = 3/n
To solve for the differences that exist between the left end point of the interval and the value of x at the right end of the k-th rectangle, one can say that:
k·(3/n) = 3k/n
Note that the value of x at shows the point of difference added to the interval's left end and thus it will be: 2 + 3k/n
Therefore, the value of the function for the value of x will be:
f(2 +3k/n) = 2(2 +3k/n) +1 = (4 +6k/n) +1
= 5 +6k/n

The experimental probability that the next train to pull in will be full is [tex]\rm \frac{4}{5}[/tex]. Probability is the ratio of the favorable event to the total number of events.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.
The experimental probability that the next train to pull in will be full is found as;

Estimate 17.26+4.556 by first rounding each number to the nearest tenth. I need help
Answer:
21.9
Step-by-step explanation:
When rounding to the nearest tenth, we are rounding to 1 decimal place.
If the number in the hundredth place is 5 or more, we round up.
If the number in the hundredth place is less than 5, we round down.
17.26 rounded to the nearest tenth is 17.3
as 6 is in the hundredth place, so we round 2 tenths up to 3 tenths.
4.556 rounded to the nearest tenth is 4.6
as 5 is in the hundredth place, so we round 5 tents up to 6 tenths.
Therefore, 17.3 + 4.6 = 21.9

Answer: Commutative Property of Addition
Explanation:
This is the rule which says that we can add two numbers in any order.
For example, 3+2 = 2+3 since both sides result in 5. The rule can be extended to involve variables, because variables are placeholders for actual numbers. Also, the rule can be extended to any number of terms and not just two.
A more generalized form of the rule could be something like x+y = y+x

-2x + 4y = 12
5x - 2y = 10
To answer please type altogether with no spaces. For example if your answer is negative three positive four, type (-3,4)
Answer:
(4,5)
Step-by-step explanation:
-2x + 4y = 12
5x - 2y = 10
make them both set to y
4y = 2x + 12 -> y = 1/2x + 3
2y = 5x - 10 -> y = 5/2x - 5
since they're both equal to y, they are equal to each other
1/2x + 3 = 5/2x - 5
2x = 8
x = 4
plug it back in to get y
y = 1/2 (4) + 3
y = 5
