3. Beats wireless headphones are on sale for 97.50. If the price represents a 35% discount
from the original price, what is the original price?
a.
Answer:
Original price= $150
Step-by-step explanation:
Giving the following information:
Sales pirce= $97.5
Sales discount= 35% decrease
To calculate the original price, we need to use the following formula:
Original price= sales price / (1 - discount)
Original price= 97.5 / 0.65
Original price= $150

When comparing a single sample to a population mean, a one sample t test must be used instead of a one sample z test when what value is unknown?
a. The sample mean
b. The population standard deviation
c. The desired alpha level
d. The sample standard deviation
e. The sample variance
Answer: b. The population standard deviation
Step-by-step explanation:
The one-sample z-test is a test that us carried out to ascertain whether the mean of a population is either greater or less than a specific value given.
The one sample t test is used in comparing the mean of the sample data of the researcher carrying out the research to a known value.
When the population standard deviation is known, the one sample z test is used while when the population standard deviation is not known, one can use the one sample t test.
In what ways do you think a cracked hard-boiled egg might serve as a model for the spatial distribution of earthquake data and the three models of plate interactions?
Answer:
- the shell is related to the egg as its outer layer just the same way the lithosphere is related to the Earth as its solid outer layer also called tectonic plate;
- the yolk is related to the egg as the centre layer just the same way the core is related to the Earth as its centre layer.
- The egg white is related to the egg as the middle layer just the same way the mantle is the middle layer of the earth
Step-by-step explanation:
A conceptual model of the relative thicknesses of the Lithosphere can be presented by measuring a simple hard-boiled egg.
The hard-boiled egg serves as a scale model for the zones of the Earth.
Now, in comparison to the earth, let's note the following;
- the shell is related to the egg as its outer layer just the same way the lithosphere is related to the Earth as its solid outer layer also called tectonic plate;
- the yolk is related to the egg as the centre layer just the same way the core is related to the Earth as its centre layer.
- The egg white is related to the egg as the middle layer just the same way the mantle is the middle layer of the earth
These comparative similarities gives us the strong idea that the lithosphere
is considered as a thin shell.

Find the unit rate:150 people for 5 classes
Answer:
The unit rate would be 30 (meaning 30 per class, making the unit rate of each class 30)
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
150 people for 5 classes is 150:5
divide both 150 and 5 by a common factor, 5
150/5:5/5 is 30:1
the unit rate is 30:1 which is 30

HELP WILL GIVE BRANLIEST!!
Answer:
on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.
Now
On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)
But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2
In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together
So our required answer is
p(even number)× p(tails)= 1/2 × 1/2 = 1/4

Figure J does not show y as a function of x ⇒ D
Step-by-step explanation:
y is a function of x if and only if every x has only one value of y
Let us check each given figure if it shows a function or not
#Figure F
∵ Every value of x has an arrow is pointed to one value of y
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure G
∵ The ordered pairs have different values of x-coordinates
∴ Every x-coordinate has only one value of y-coordinate
∴ The figure shows y as a function of x
#Figure H
∵ Every x in the table appears once
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure J
∵ The ordered pairs were drawn in the figure are (-3, -2), (-3, -3), (-2, 0),
(-2, -1), (-1, 1), (-1, 2), (0, 3), (0, 4)
∵ x = -3 has two values of y, y = -2 and -3
∵ x = -2 has two values of y, y = 0 and -1
∵ x = -1 has two values of y, y = 1 and 2
∵ x = 0 has two values of y, y = 3 and 4
∴ Every x-coordinate has more than one value of y-coordinate
∴ Figure J does not show y as a function of x

A concert ticket costs $23. About how much will tickets costs for a group of 22 people?
Answer:
$506
Step-by-step explanation:
We know that 1 concert ticket is $23
Multiply 23 by 22 to get 506
They spend $506 in total for the tickets.
The total cost for a group of 22 people is $506 if a concert ticket costs $23. , the answer is $506.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A concert ticket costs $23.
Let x be the total cost for the group of 22 people:
The value of x can be found as follows:
The linear equation in one variable:
x = 23×22
x = $506
Thus, the total cost for a group of 22 people is $506 if a concert ticket costs $23. , the answer is $506.

90% of 133 is equal to (0.9) ⋅ 133 true or false
Answer:
True.
Explanation:
It’s true because a percent is based on decimals. For example, 0.01 is 1%, while 0.1 is 10%. So that means that 0.9 is 90%. Remember, “of” means multiplying. So, 0.9 times 133 is equal to 90% of 133.

Sam wants to build a fence around her property. The length of
the her fence must be one feet greater than three times its
width and the area of her property is 30 square feet. What is
the maximum width that her fence can be to ensure she
doesn't encroach into her neighbor's property?
Answer:
3.33ft
Step-by-step explanation:
Area of the fence = Length * Width
A = LW
Given
Area A = 30ft²
If the length of the her fence must be one feet greater than three times its width, then;
L = 3W + 1
Substotute into the area formula
A = (3W+1)W
30 = 3W²+W
3W²+W - 30 = 0
(3W²+9W)-(10W - 30) =
3W(W+3)-10(W+3) = 0
3W-10 = 0 and W+3 = 0
3W = 10 and W = -3
W = 10/3 and -3
Width cannot be negative
Hence the maximum width that her fence can be to ensure she doesn't encroach into her neighbor's property is 3.33ft

Which set is a subset of every set?
A. {}
B. {0}
C. {1}
Answer:
I'd say the answer is C
Answer: Choice A. { }
This is the empty set with nothing inside it. Another way to write the empty set is to use the symbol [tex]\varnothing[/tex]
The set { 0 } is not the empty set because 0 is inside it, making it nonempty. A set like {1,2,3} does not contain 0, so there's no way {0} can be a subset.
