An experiment is proposed to measure the
effectiveness of a brand of sunscreen. Adult volunteers
are randomly assigned to one of two brands of
sunscreen and asked to enjoy a normal day at the
beach. Each volunteer is asked to report back to the
administrators after two hours, at which time both arms
are assessed for sun exposure.
O The volunteers are the explanatory variables.
O. The brands of sunscreen are the response
variables.
O The amount of time in the sun is the response
variable.

Jack places the bottom of a ladder 9 feet from the wall. It is a huge 41 foot long ladder so he asks his sister Katie to help him. How far up the wall does the ladder reach?
Answer:
40 feet
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
a² + 9² = 41²
a² + 81 = 1681
Subtract 81 from both sides
a² = 1600
Take the square root of both sides
a = 40
What is the factorization of the polynomial graphed below? Assume it has no
constant factor. Write each factor as a polynomial in descending order.
Answer:
see below
Step-by-step explanation: 5 25 14 16
the graph shows the roots of the polymonimal to be
x = 0 and x - 4 = 0 x = 4 when y or f(x) = 0
f(x) = x(x-4) = x² - 4x
f(x) = x² - 4x
when x = 0 f(x) = 0
x = 2 f(x) = 2² - 4(2) = -4
x = 4 f(x) = 4² - 4(4) = 0
The factorization of the polynomial graphed are,
⇒ y = x (x - 5)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now, We have been given graph of polynomial.
This is in parabolic shape.
So, this is graph of quadratic function.
Hence,, there will be two zeroes.
And also number of zeroes of a function is equal to the number of times graphs cuts x-axis
Here, we can see graph cuts at (0,0) and (5,0).
So, the Factors will be:
(x - 0) and (x - 5).
Since, If x = 0 is a zero then it means factor will be (x)
Similarly, If x = 5 is a zero then it means factor will be (x-5).
Thus, the factorization of the polynomial graphed are,
⇒ y = x (x - 5)

Gun rights vs. gun control: In a December 2014 report, "For the first time in more than two decades of Pew Research Center surveys, there is more support for gun rights than gun control." According to a Pew Research survey, 52% of Americans say that protecting gun rights is more important than controlling gun ownership. Gun rights advocates in a conservative city believe that the percentage is higher among city residents.
They survey 200 city residents and find that 130 say that protecting gun rights is more important than controlling gun ownership. What is the test statistic?
Z = -3.68
Z = 3.68
Z = -3.85
Z = 3.85
Answer:
The right answer is "z = 3.68".
Step-by-step explanation:
Given that,
p = 52%
or,
= 0.52
n = 200
[tex]\hat{p}= \frac{130}{200}[/tex]
[tex]= 0.65[/tex]
Now
The test statistic will be:
⇒ [tex]z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]
On substituting all the given values, we get
⇒ [tex]=\frac{0.65-0.52}{\sqrt{\frac{0.52(1-0.52)}{200} } }[/tex]
⇒ [tex]=\frac{0.13}\sqrt{{\frac{0.52\times 0.48}{200} }}[/tex]
⇒ [tex]=\frac{0.13}{\sqrt{0.001248} }[/tex]
⇒ [tex]=3.68[/tex]
a man swims for 30 mins at a speed of 109 m/min. How far does he swim?
The distance is meters per minute so you would multiply the distance per minute by total minutes:
109 x 30 = 3.270 total meters.
1 km = 1000 meters
3,270 meter/ 1000 meters per km = 3.27 km
They swam 3.27 km

printer charges $200 plus $2 for every poster. How many posters can be
printed for $950?
Answer:
375 posters can be printed for $950
Step-by-step explanation:
First, create an equation. X = number of posters: 200+2x=950
Second, subtract 200 from both sides to get an equation of: 2x=750
Third, divide 2 on both sides to get: x = 375
