a data survey representative calls phone numbers selected at tandom until someone answers. each call has a .22 probability of someone answering it. let N be the number of calls until someone answers.
What type of variable is N?
Binomial, geometric or neither?
Since the number of trials is not fixed, N is neither a binomial or a geometric variable, it is an inverse binomial variable.
The sample is chosen at random, hence, the trials are independent, that is, each person has the same probability of answering it, hence N is not a geometric variable.
For it to be a binomial distribution, there needs to be a fixed number of trials, which there is not, hence, N is also not a binomial variable.
The distribution that counts the number of trials until x successes in the inverse binomial distribution, which means that N is an inverse binomial variable.A similar problem is given at https://brainly.com/question/25644451

5x -25 =105 fin the value of x
Answer:
26
Step-by-step explanation:
5(26)-25
5*26=130
130-25=105
Answer:
To find the value, isolate x.
5x - 25 = 105
Add 25 to both sides.
5x = 130
Divide both sides by 5.
x = 26

Tyler has $600 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $233.09.
He buys 3 bicycle reflectors for $16.38 each and a pair of bike gloves for $29.13.
He plans to spend some or all of the money he has left to buy new biking outfits for $52.48 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Tyler can purchase while staying within his budget.
I need this asap!
Answer:
5 outfits
Step-by-step explanation:
The total of Tyler's purchases will be ...
233.09 +3(16.38) +29.13 +52.48x ≤ 600
52.48x ≤ 288.64 . . . . . . . . . subtract 311.36 and simplify
x ≤ 5.5 . . . . . . . . . . . . . . divide by 52.48
Tyler can buy 5 outfits and stay within his budget.
_____
The number of outfits must be an integer. The largest integer less than 5.5 is 5.
Using the diagram and information below to create and solve an equation m<2 =(y+10)° and m<4=(3y-24)° what is m <2
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
Can someone please help how I could find the square root for 121? Please explain step by step to get marked as brainliest!
Answer:
+ or - 11
Step-by-step explanation:
To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive. I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.
Hope this helps! :)

find the slip of every line that is parallel to the graph of the equation x-8y=-1
Answer:
1/8
Step-by-step explanation:
x-8y=-1
First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
-8y = -x-1
y = 1/8x +1/8
The slope is 1/8 and the y intercept is 1/8
The slope for parallel lines is the same for all parallel lines
1/8

Hannah is organizing her jewelry box. She wants to divide the 30 charms for her bracelet into two equal
groups, so that the ratio is 2 to 3. How many charms should Hannah put in each group?
Uisng the ratio concept, the number of charms that should be put into each group would be 12 and 18 respectively
Given the Parameters :
Total number of charms = 30Ratio = 2 : 3The group with 2 :
[2 ÷ (2+3)] × 30
(2 / 5) × 30
= 12
The group with 3 :
[3 ÷ (2+3)] × 30
(3 / 5) × 30
= 18
Hence, each group will have 12 and 18 charms respectively

Answer:
X= - 1/6
Step-by-step explanation:
Well its 16/7 = -8x
We can do a proportion over here
so 16/7 = -8x/1
Now just cross multiply to solve proportion
-56x=16
divide -56 to isolate x
x= 16/-56
Now simplify 16/-56
which is -1/6
So negative 1/6
Answer: x=-2/7

1 Solve the system of equations by the substitution method. 5x+10y = 30 4x + 8y = 36 Select the correct choice below and fill in any answer boxes within your choice. A. The solution is (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions: {(x,y)|5x + 10y = 30} or {(x,y)|4x + 8y = 36}. C. There is no solution: Tor .
The system of equations:
5x + 10y = 30
4x + 8y = 36
Has no solutions, the correct option is C.
How to solve the system of equations?Here we have the system of equations:
5x + 10y = 30
4x + 8y = 36
We want to use the substitution method, then we need to isolate one of the variables. Let's work with the second equation:
4x + 8y = 36
Divide by 4:
x + 2y = 9
x = 9 - 2y
Now replace that in the other equation to get:
5*(9 - 2y) + 10y = 30
45 - 10y + 10y = 30
45 = 30
This is a false equation, thus, the system has no solutions.

Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1: If Athlete J continues at that speed, how long will it take to run one mile?
2: How long will it take Athlete J to run 5 miles at that same speed?
3: Who runs faster, J or H? Why?
The number of minutes it would take Athlete J to run one mile is 12 minutes.
The number of hours it would take Athlete h to run 5 miles is 10/11 hour.
Athlete h runs faster because his average speed is greater than that of Athlete J.
In order to determine the time it would take Athlete J to run one mile, the average speed has to be determined.
Average speed = total distance / time
2/3 ÷ 8
2/3 x 1/8 = 1/12 mile / minute
Time it would take Athlete J to run one mile = distance / speed
1 ÷ 1/12 = 12 minutes
Average speed of Athlete H = 2 3/4 ÷ 1/2
11/4 x 2 = 5 1/2 miles / hour
Time it would take Athlete H to run 5 miles = distance / speed
5 ÷ 11/2
5 x 2/11 = 10/11 hours

Answer:
218
-72
12° C
Step-by-step explanation:
The magnitude of a single number is the positive version of that number.
We write it mathematically like this:
|−218|=218
|-12|=12
The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.
For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.
