Answer:
456.73 cm²
Step-by-step explanation:
Area of a circle = πr²
The radius of the hub cap
= 75.74÷3.14÷2
= 12.06 cm (rounded to the nearest hundredth)
The area of the hub cap
= 3.14 × 12.06²
= 456.7314968152...
= 456.73 cm² (rounded to the nearest hundredth)
Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.
So the area of the hub cap will be smaller.
Find the volume. Round to the nearest tenth if necessary?
answer:
v=1282.8 or 1282.82
step-by-step explanation:
v=πr²h/3
=π*7²*25/3

https://socratic.org/questions/how-do-you-solve-2sinx-1-0#270365
If the value of a in the quadratic function f(x) = ax2 + b3 + cis , the function will:
open down and have a maximum
open down and have a minimum
open up and have a minimum
open up and have a maximum
If the value of a in the quadratic function f(x) = ax² + bx + c is 1/2, the function will: C. open up and have a minimum.
What is the general form of a quadratic function?In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;
y = ax² + bx + c
Where:
a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.Since the leading coefficient (value of a) in the given quadratic function f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

because the formula for the triangle is 1/2×b×h
and the formula for the rectangle nos l×w and then add those.
Answer:
A = 60yd
Step-by-step explanation:
First "separate" the rectangle and the triangle in your head.
Now calculate the area of the rectangle and then the area of the triangle.
Rectangle: 6*8 = 48
Triangle: (6*4)/2 = 24/2 = 12
Now we add them together:
48 + 12 = 60yd

What is the perimeter?
meters
Answer: 20+21+20+21=40+42=82
Step-by-step explanation:
Add up the sides
Multiply by 2
Try:
20+21=41
Multiply by 2:82
Answer:
82 meters
Step-by-step explanation:
to get the perimeter of a rectangle or square you have to add the lengths of all the four sides
P=20+20+21+21
P=2x20+2x21
P=2x(20+21)
P=2x41
P=82
The National Sleep Foundation recommends that teenagers aged 14 to 17 years old get at least 8 hours of sleep
per night for proper health and wellness.
A statistics class at a large high school suspects that students at their school are getting less than 8 hours of
sleep on average. To test their theory, they randomly sample 42 of these students and ask them how many hours
of sleep they get per night. The mean from the sample is 2 = 7.5 hours.
Here's their alternative hypothesis:
H : The average amount of sleep students at their school get per night is...
What is an appropriate ending to their alternative hypothesis?

Ms. Strickland is practicing the piano for an upcoming recital. The table list the number of minutes she practiced in the past few weeks.
a. What is the median number of minutes she practiced?
b.What is the range of the data?
c.What is the mean number of minutes that she practiced?
Answer:
a. 20
b. 32
c. 20.6
Step-by-step explanation:
Median is the middle number- so put the numbers in order from least to greatest, and find the middle number
8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40
Median is 20
the range is the difference between the largest and the smallest value- 40-8 is 32
Mean is the average- add all the values and divide by the total number of values (13)
268 minutes divided by 13 days
mean is about 20.6 minutes
Help please !!! Need help
Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234

Step-by-step explanation:
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Joseph sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 103 visitors purchased no costume. 161 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase more than one costume as a decimal to the nearest hundredth.
The probability that the next person will purchase more than one costume is 0.03
How to solve for the probabilityWe have the following details to solve the problem with
The people that did not purchase any costume = 103
Those that purchased exactly one costume = 161
Those that purchased more than one costume = 7
The total number of persons that we have here would be
103 + 161 + 7
= 271
We are to find the probability that the next would purchase more than 1 costume.
This is given as:
7 / 271 = 0.0258
To the nearest hundredth = 0.03
Hence, 0.03 is the probability that the next person is going to buy more than one costume.

Answer:
81%
Step-by-step explanation:
27 no costume, 112 exactly one costume, 3 more than one costume.
27+112+3=142
There were a toal of 142 customers. 112+3=115 visitors purchased one or more costumes costumes.
Probability the next visitor will purchase one or more costumes:
115/142=0.809859
0.809859 times 100% = 80.9859%
which rounds to 81%
The probability as a percent to the nearest whole number is 81%
