Eliza intends to buy a new vehicle. She wishes to estimate the mean fuel efficiency (in miles per gallon) of all family sized SUV's currently available on the market. Eliza selects a random sample of 15 family sized SUV's and looks up their fuel efficiency on a trusted website. The results of the random sample are shown below:
27, 28, 30, 28, 28, 31, 29, 33, 28, 28, 31, 33, 41, 41, 25
What is the mean fuel efficiency rounded to the nearest whole number?
Question 1 options:
28
29
30

Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31

does anyone know adjacent angles ? i am guessing it more than 1 by the way please help.
Answer:
∠SRP and ∠QRP
∠TUR and ∠VUR
Step-by-step explanation:
Adjacent angles are angles that share a common side and have the same vertex. Here you need to see if each pair share a side and start at the same point.
∠SRP and ∠QRP: These are adjacent because they share the same vertex and side
∠TUR and ∠VUR: These are adjacent because they share the same vertex and side
∠QRP and ∠VUW: These are not adjacent because they do not share the vertex, only share a common side
∠TUR and ∠SRU: These are not adjacent because they do not share the vertex, only share a common side

Q2: One end of a cable is attached to the top of a flagpole and the other end is attached 6 feet away from the base of
the pole.
If the height of the flagpole is 12 feet, find the length of the cable,
Answer:
13.4 feet
Step-by-step explanation:
a²+b²=c²
12²+6²=c²
144+36=[tex]\sqrt{180}[/tex]
=13.4
The length of the cable is 13.416 feet.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have one end of the cable is attached to the top of a flagpole.
The other end is attached 6 feet away from the base of the pole.
The flagpole height = 12 feet
As we can see in the figure it is a right angle triangle in which the:
The length of the base of the right angle triangle b = 6 feet
The length of the perpendicular l = 12 feet
From the Pythagoras theorem:
[tex]\rm Hypotenuse^2 = Base^2+Perpendicular^2[/tex]
Let's suppose the length of the cable is x feet
[tex]\rm x^2 = 6^2+12^2[/tex]
[tex]x^2 = 36+144 \Rightarrow 180[/tex]
[tex]\rm x = \sqrt{180}[/tex]
x = 13.416 feet
Thus, the length of the cable is 13.416 feet.

The unit of measure of the of the conversion factor should be the unit of
measure which you want to convert.
The correct use of conversion factors will result in the cancellation of the unwanted units and retention of the desired unit.
Conversion factors are essential in unit conversions, allowing us to switch from one unit of measurement to another within the same system, such as U.S. customary units or the SI unit system. To use conversion factors effectively, one must ensure that the unit of measure they wish to convert from or to is correctly positioned in the conversion factor equation. For instance, when converting meters to centimeters, a factor of 1 cm/10-2 m or 100 cm/1 m is used because 'centi' means 10-2 in the SI unit system.
It is important to keep track of units being canceled during the conversion. If you have units in the numerator and denominator that are the same, they will cancel out, leaving only the desired unit. In the process of conversion, if the unit you want to convert is in the denominator of the original quantity, the conversion factor should have that unit in the numerator.
Choosing the right conversion factor and accurately performing the calculations are crucial. A proper conversion factor will cancel out unwanted units. Using an incorrect conversion factor without an opposing unit to cancel out will leave an unwanted unit in your answer, indicating an error in the process.
Dimensional analysis, which often involves conversion factors, simplifies the process of converting units and ensures that measurements within calculations are consistent. This technique is fundamental for scientific calculations and everyday applications, such as determining the appropriate unit to measure large volumes or distances.
Which figure has a greater volume and by how much?
The volume of figure 1 is 45 centimeters cubed greater than the volume of figure 2.
The volume of figure 2 is 45 centimeters cubed greater than the volume of figure 1.
The volume of figure 1 is 120 centimeters cubed greater than the volume of figure 2.
The volume of figure 2 is 120 centimeters cubed greater than the volume of figure 1.
Answer:
A) The volume of figure 1 is 45 cm³ greater than the volume of figure 2
Step-by-step explanation:
Let's start by calculating the volumes of both figures
Figure 1
Rectangular prism
V = Bh
V = (15*6)(5)
V = (90)(5)
V = 450 cm³
Triangular prism
V = Bh
V = 1/2(3*15)(6)
V = 1/2(45)(6)
V = 1/2(270)
V = 135 cm³
Add them together, you get 585 cm³
Figure 2
Rectangular prism
V = Bh
V = (6*15)(5)
V = (90)(5)
V = 450 cm³
Rectangular pyramid
V = 1/3 Bh
V = 1/3 (15*6)(3)
V = 1/3 (90)(3)
V = 1/3 (270)
V = 90 cm³
Add them together, you get 540 cm³
Subtract 540 from 585 and get 45
Answer:
A) The volume of figure 1 is 45 cm³ greater than the volume of figure 2

Answer:
(4, 0) and (6, 0)
Step-by-step explanation:
The function that we have is:
[tex]g(x)=x^2-10x+24[/tex]
This is the function of a parabola.
to find the points where the function crosses the x-axis, we need to find the values of x for which g(x) (which is the value of the y-axis) is equal to zero.
so we need [tex]g(x)=0[/tex] for the function to be crossing the x-axis.
Thus our equation becomes:
[tex]x^2-10x+24=0[/tex]
and we can solve this equation with the quadratic formula or by factoring.
I will sove by factoring:
To factor this type of equations we need to find 2 number that satisfy the following:
when multiplied result in +24 (the independent number of the equation) and when added or substracted result in -10 (the coefficient of the x in the equation)In this case those 2 number are: -6 and -4 because:
(-6)(-4)=+24
-6 - 4 = -10
Thus we arrange our factored equation as follows:
from [tex]x^2-10x+24=0[/tex] through factoring we get:
[tex](x-6)(x-4)=0[/tex]
and because of the zero factor property (if two things when multiplied result in zero one of them or both must be zero), thus our x values are:
[tex]x-6=0\\x=6\\[/tex]
and
[tex]x-4=0\\x=4[/tex]
thus, our points are those with and y coordinate of 0 and an x coordinate of 6 and 4:

Jordan fills several bags with oranges. This line plot shows the weight of each bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?
Enter your answer as a fraction in simplest form by filling in the boxes.
The heaviest bag has (1 + 1/8) lb more than the lightest bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?By looking at the histogram, we can see that the heaviest bag weighs:
M = (5 + 1/2) lb
The lightest bag weighs:
m = (4 + 3/8) lb
Now we need to take the difference between these masses:
M - m = (5 + 1/2) lb - (4 + 3/8) lb = (5 - 4) lb + (1/2 - 3/8) lb
M - m = 1 lb + (4/8 - 3/8)lb = (1 + 1/8)lb
This means that the heaviest bag has (1 + 1/8) lb more than the lightest bag.

An animal shelter randomly selects 30 dogs and finds 4 are classified as small breeds because they are under 25 pounds.
If there are 105 total dogs in the shelter, enter the number predicted to be small breeds.
Answer:
14
Step-by-step explanation:
14 out of 105= 7.5
4 out of 30= 7.5
Both numbers, 14 and 4, have the same ratio.
There are 14 small breed dogs in the shelter.
The question involves using proportional reasoning to predict the number of small breed dogs in a shelter. From the given sample of 30 dogs, 4 are classified as small breeds. To find the predicted number of small breeds in the entire shelter, we set up a proportion based on the sample proportion:
4 small dogs out of 30 total dogs (sample) = x small dogs out of 105 total dogs (shelter).
Solving for x gives us the predicted number of small breed dogs:
(4/30) * 105 = x
Calculate the value of x:
x = (4* 105) / 30
x = 420 / 30
x = 14
Therefore, based on the sample, we would predict that there are 14 small breed dogs in the shelter.
