[tex]P(x \le 10) = 0.85[/tex]
Step-by-step explanation:
Given
See attachment for properly presented question
Required
[tex]P(x \le 10)[/tex]
From the question, we understand that he takes 40 shots (trials)
So:
[tex]n = 40[/tex]
From the attached plot, the number of attempts up to the 10th is:
[tex]x \le 10 = 9+6+5+4+4+2+2+0+1+1[/tex]
[tex]x \le 10 = 34[/tex]
So, we have:
[tex]P(x \le 10) = \frac{n(x \le 10)}{n}[/tex]
[tex]P(x \le 10) = \frac{34}{40}[/tex]
[tex]P(x \le 10) = 0.85[/tex]

The crayon balloon is made up of a cone and a cylinder. What is the volume, in cubic inches, of the crayon balloon?
A) 69.12
B) 75.40
C) 138.23
D) 276.46
Answers
Answer:
A. 69.12 in.³
Step-by-step explanation:
Volume of the crayon balloon = volume of the cone + volume of the cylinder
= ⅓πr²h + πr²h
✔️Volume of Cone = ⅓πr²h
r = ½(2) = 1 in.
h = 3 in.
Volume of cone = ⅓*π*1²*3 = 3.142 in.³
✔️Volume of Cylinder = πr²h
r = ½(2) = 1 in.
h = 21 in.
Volume of Cylinder = π*1²*21 = 65.97 in.³
✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115
= 69.12 in.³ (nearest hundredth)

Step-by-step explanation:
There is not enough information to make a conclusion about the population mean. Then the correct option is B.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A class is gathering data on the amount of time spent watching videos each day.
Each student collected 10 pieces of data and will compile that data to determine a population mean.
One student, Megan, has a sample mean of 45.67.
The population mean can be approximated by the mean of an unlimited number of sampling means within the group according to the central limit theorem.
It is not possible to determine the population from Megan's sample mean because it only represents a small portion of the whole population.
There is not enough information to make a conclusion about the population mean.
Then the correct option is B.

If Sarah walks to the Springdale Town Center from the Ferguson
Corporation and then to the Subway Station, how much farther will she
walk than if she walks directly to the Subway Station from the Ferguson
Corporation? Show all of your work.
Answers
Answer:
1263.7032 feets
Step-by-step explanation:
Distance from Ferguson corporation to Springdale Town center ; let the distance = x
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 27 = x / 2000
0.5095254 * 2000 = x
1019.0508 feets
Distance from Springdale to Subway station, this is the hypotenuse :
Hypotenuse = √(1019.0508² + 2000²)
Hypotenuse = √5038464.7
Hypotenuse = 2244.6524 feets
Total distance walked from Ferguson to Springdale, then to Subway ;
(1019.0508 + 2244.6524) feets = 3263.7032 feets
Additional distance walked :
(3263.7032 feets - 2000 feets) = 1263.7032
In this exercise we have to calculate the distance knowing about the laws of a triangle, so we have to:
[tex]H=1263.7032 feets[/tex]
We can use the definition of tangent to calculate:
[tex]Tan\theta = opposite / Adjacent\\Tan 27 = X / 2000\\0.5095254 * 2000 = X\\=1019.0508 feets[/tex]
Now using the Pythagorean theorem we have:
[tex]H = \sqrt{(1019.0508^2 + 2000^2)}\\H = \sqrt{5038464.7}\\H = 2244.6524 feets\\(1019.0508 + 2244.6524) = 3263.7032 feets\\(3263.7032 feets - 2000 feets) = 1263.7032[/tex]

The required conditional probability would be 0.71.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The conditional probability is defined as:
P(A|B) = P(A∩B)/P(B)
From the given two-way table, we get
Drive to school and senior = 25
Senior = 25+5+5
= 35
Total = 2+25+3+13+20+2+25+5+5
= 100
Now,
P( Drive to School and Senior) = 25 / 100
P( Senior) = 35/ 100
Thus,
P( Drive to School | Senior) = 25 / 35 = 0.71
Therefore, the required conditional probability would be 0.71.

Maryanne went to lunch with a friend. The bill was $35.60 before tax. Sales tax rate is 7.25%, and she
decided to leave a 15% tip. What was the final total of her lunch bill?
Answers
Answer:
$43.91
Step-by-step explanation:
Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
$35.60 + $2.58 (tax) = $38.18
$38.18+ $5.73 (tip at 15%) = $43.91 total

Helen practiced the piano 5 days last week. The list below shows the number of minutes she practiced each day: 20,25,30,20,30 What is the MAD (mean absolute deviation) in Helen's practice times?
Answers
Answer:
4
Step-by-step explanation:
Given the data:
X : 20,25,30,20,30
Mean absolute deviation :
Σ(x - xbar) / n
n = sample size = 5
xbar = ΣX / n = (20+25+30+20+30) /5
xbar = 25
((20-25) + (25-25) + (30-25) + (20-25) + (30-25)) / 5
We take the absolute values, hence, negative signs are ignored :
(5 + 0 + 5 + 5 + 5) / 5
20 / 5
= 4

The value of a new car depreciates (loses value) in many ways. First, a new car can depreciate in value once it is purchased and driven off the car lot. After that the value of a car depreciates each year because it is one year older. Let's consider two different cars:
Car A Car B
Purchase Price $30,000 and $25,000
Precent of Initial Depreciation
20% 10%
Yearly Depreciation $2,000 $1,500
Based on the data answered in the previous three questions, write an equation to predict the value of Car A and Car B at the end of t years.
Car A: V =
t +
Car B: V =

Answers
Answer:
Your car's value decreases around 20% to 30% by the end of the first year. From years two to six, depreciation ranges from 15% to 18% per year, according to recent data from Black Book, which tracks used-car pricing. As a rule of thumb, in five years, cars lose 60% or more of their initial value.
