Most dermatologists recommend using sunscreens that have a Sun Protection Factor (SPF) of at least 30. One of the authors wanted to find out whether the SPF of sunscreens used by students at her school exceeds this value on average? To collect data, the author surveyed students in her introductory statistics course and found that in a sample of 52 students the mean SPF was 34.55 and the standard deviation of SPF was 20.12. The data were not strongly skewed.
Required:
Use the Theory-Based Inference applet to find and report the 95% confidence interval for the parameter of interest.
Answer:
95% confidence interval = ( 28.9485, 40.1515 )
Step-by-step explanation:
sample size( n ) = 52
mean value ( x )= 34.55
std ( б ) = 20.12
H0 : u ≤ 30
Ha : u > 30 ( claim )
95% confidence interval for mean SPF level ( df = 51 )
= mean value ± [tex](2.0076 + \frac{20.12}{\sqrt{52} } )[/tex]
95% confidence interval = ( 28.9485, 40.1515 )
we cannot reject H0

What causes a stars to shine brightly?
Answer:
Stars are actually exploding when you see them, so the light is produced from the explosion.
Step-by-step explanation:
:)
Answer: Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars.
Step-by-step explanation:
In most stars, like our sun, hydrogen is being converted into helium, a process that gives off energy that heats the star, this energy also causes the star to shine brightly.
Two times the sum of a number and twelve is 40. What is the number?
Answer:
8
Step-by-step explanation:
n= that number
2(n+12)=40
2n+24=40
-24 -24
2n=16
2n/2=16/2
n=8
Answer:
the number is 8
Step-by-step explanation:
2(12 + n) = 40
24 + 2n = 40
2n = 16
n = 8

Answer:
Where cgym is the cost after m months. To find when the cost is equal, equate the right side of both equations and solve for m :.
Answer:
13 months because 13 x 20 is 260 plus the sign-up fee is 300$ all together

I am just not sure if I did this properly. My professor hasn't really gone over when to use the range equation but I would assume range would equal the distance traveled therefore can be used for this problem. If not the how would I go about solving this? I did 1/6*9.8=1.63 for g on the moon Then used R=(Vi^2sin2theta)/g so on the moon R=((28^2)sin2*35)/1.63=452m

What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
Given that;
A robot can complete 7 tasks in 2/5 hour.
Each task takes the same amount of time.
Now,
Since, 7 tasks = 2/5 hour
So, 1 tasks = 2 / 5×7
= 2 / 35 hour
Thus, The robot take 2 / 35 hour to complete one task.
And, 2/5 hour = 7 tasks
So, 1 hour = 7 x 5 / 2
= 35 / 2
Thus, The robot complete 35/2 tasks in one hour.
Therefore,
a) The robot take 2 / 35 hour to complete one task.
b) The robot complete 35/2 tasks in one hour.

A 10 2/3 -inch long pipe is cut into 8 equal length pieces. How long is each piece?
Answer:
Each peice is 1 1/3 (4/3) long.
Step by step explanation:
10 2/3 divided by 8
10 2/3 = 32/3
32/3 divided by 8 = 32/3 x 1/8
32 times 1 = 32, 3 times 8 = 24 =32/24
32/24 in simplest form is 4/3 (aka 1 1/3)

Write an equation of the line, in point-slope form, that passes through the two given points. points: (-3,18). (12,-12)
Answer:
y = -2x + 12
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-12 - 18) / (12 + 3)
-30 / 15
= -2
Then, plug this and a point into y = mx + b and solve for b:
y = mx + b
-12 = -2(12) + b
-12 = -24 + b
12 = b
Then, plug in the slope and b into y = mx + b
y = -2x + 12 is the equation of the line

Use the domain {-1, 0, 1, 2, 3} and plot the points on the graph that would best satisfy the equation. The bold grid marks represent one unit, the horizontal red line represents the x-axis while the vertical red line represents the y-axis.
y = 2x
Answer:
Plot the following points on the graph
[tex](-1, \frac{1}{2})[/tex], (0, 1), (1, 2), (2, 4), (3, 8)
Step-by-step explanation:
If the equation for the line is y = [tex]2^{x}[/tex], whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.
For example, if our domain is {-1, 0, 1 , 2, 3}
then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.
If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.
[tex]y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}[/tex]
If x = 0, then y = 1
**When the exponent is 0, the number automatically equals 1.
If x = 1, then y = 2.
If x = 2, then y = 4
If x = 3, then y = 8
So you would plot the following coordinates on the graph:
[tex](-1, \frac{1}{2})[/tex]
(0, 1)
(1, 2)
(2, 4)
(3, 8)
