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?

One hexagonal prism has dimensions that are triple the dimensions of a similar hexagonal prism. If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
4.75 cm3
14.25 cm3
42.75 cm3
128.25 cm3
Answer:
128.25 cm³
Step-by-step explanation:
Volume of an hexagonal prism:
The volume of an hexagonal prism is given by:
[tex]V = \frac{3\sqrt{3} a^2h}{2}[/tex]
In which a and h are the dimensions.
Triple the dimensions
This means that the volume will be multiplied by 3^3, 27(as there are 3 terms which are dependent of the dimensions, a² and h).
If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
27*4.75 = 128.25 cm³
128.25 cm³ is the answer
Answer:
128.25 cm3

Answer:
A) 6.25x+7.50=26.25
Step-by-step explanation:
To find how much she payed for every round she played (woah that rhymed) you multiply 6.25 by the amount of rounds she played, which is x.
That's where we get 6.25x
7.50 is the base cost, so she will pay that much regardless of how much she played.
26.25 is the total amount of money spent. The admition cost and how much she spent on playing ads up to her total cost

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%

Andrew picks one marble at a time from a box and replaces it. He
repeats this process 25 times and records the results in the table. Based
on the table, which color marble has an experimental probability of 1/5?
4
Green
10
Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.

2. The half-life of BRADIUM-29 is 15 years. If you have 8 ounces of this strange substance today, how much will you
have left after 35 years?
题
SKU
Answer:
You will have 1.585 left after 35 years.
Step-by-step explanation:
Equation for amount of a substance:
The equation for the amount of a substance, using exponential decay, is given by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal.
The half-life of BRADIUM-29 is 15 years.
This means that [tex]A(15) = 0.5A(0)[/tex]. We use this to find r.
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]0.5A(0) = A(0)(1 - r)^{15}[/tex]
[tex](1 - r)^{15} = 0.5[/tex]
[tex]\sqrt[15]{(1 - r)^{15}} = \sqrt[15]{0.5}[/tex]
[tex]1 - r = (0.5)^{\frac{1}{15}}[/tex]
[tex]1 - r = 0.9548[/tex]
Then
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = A(0)(0.9548)^t[/tex]
You have 8 ounces of this strange substance today
This means that [tex]A(0) = 8[/tex]. So
[tex]A(t) = A(0)(0.9548)^t[/tex]
[tex]A(t) = 8(0.9548)^t[/tex]
How much will you have left after 35 years?
This is A(35). So
[tex]A(t) = 8(0.9548)^t[/tex]
[tex]A(35) = 8(0.9548)^{35} = 1.585[/tex]
You will have 1.585 left after 35 years.

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:
Suppose Y(t) = 25e^3t + 12 represents the number of bacteria present at time t minutes. At what time will the population reach 100 bacteria? ( Note: Answers are expressed in terms of natural logarithm
Given:
The given function is:
[tex]Y(t)=25e^{3t}+12[/tex]
Where Y represents the number of bacteria present at time t minutes.
To find:
The time taken by bacteria population to reach 100 bacteria.
Solution:
We have,
[tex]Y(t)=25e^{3t}+12[/tex]
Putting [tex]Y(t)=100[/tex], we get
[tex]100=25e^{3t}+12[/tex]
[tex]100-12=25e^{3t}[/tex]
[tex]88=25e^{3t}[/tex]
Divide both sides by 25.
[tex]\dfrac{88}{25}=e^{3t}[/tex]
Taking ln on both sides, we get
[tex]\ln (\dfrac{88}{25})=\ln e^{3t}[/tex]
[tex]\ln(\dfrac{88}{25})=3t[/tex] [tex][\because \ln e^x=x][/tex]
Divide both sides by 3.
[tex]\dfrac{1}{3}\ln(\dfrac{88}{25})=t[/tex]
Therefore, the required time is [tex]\dfrac{1}{3}\ln(\dfrac{88}{25})[/tex] minutes.
