Derrick needs to figure out how he’s doing on his test scores so far this year. You can help by calculating the mean and the median to get an overall picture of his scores. Below are all of his scores:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Answers
Answer:
Mean = 74.4
Median = 81.5
Step-by-step explanation:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Mean = Sum of values / Number of values
Number of values = 10
= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10
= 744/10
= 74.4
Median
Rearranging the given data
= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100
Formula for median = 1/2(n + 1)th value
n = 10
Hence
1/2(10 + 1)th value
1/2(11)th value
= 5.5 th value
This fall between the 5th and 6th value
5th value = 78
6th value = 85
Hence: 78 + 85/2
= 163 / 2
= 81.5

let f(x) = 1/x-3 and g(x) = the square root of x+5. What is the domain of (f o g) (x)
Answers
Answer:
the second one
Step-by-step explanation:
Option B is correct. the required domain of the function will be expressed as [-5, 3) U (3, ∞)
The domain of a function is the input function for which a function exists.
Given the functions
f(x) = 1/x-3
g(x) = √x+5
Get the composite function (f o g) (x)
(f o g) (x) = f(g(x))
f(g(x)) = f( √x+5)
[tex]f(g(x)) =\frac{1}{\sqrt{x+5}-3 }[/tex]
According to the function gotten, we can see that the domain of the fucntion will exist for all values of x except at x = 4. The function tends to infinity at x = 4. Hence the required domain of the function will be expressed as [-5, 3) U (3, ∞)

The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?
Answers
Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.

C) 74 meters
D) 15.748 meters
E) 1.5748 meters
F) None of the above
Answers
Answer:
A, 1.8796
Step-by-step explanation:
First, convert everything to inches
6 × 12 = 72
72 + 2 = 74
Now, we convert the inches to centimeters
2.54 × 74 = 187.96
Next, we convert to meters
187.96 ÷ 100 = 1.8796
So, your answer would be A, 1.8796 meters

Answer:
y = [tex]\frac{24}{x}[/tex]
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 4 when x = 6 , then
4 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
24 = k
y = [tex]\frac{24}{x}[/tex] ← equation of variation

Shape C is A trapezoid
Area of trapezoid = [tex]\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.
[tex]A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16[/tex]
Hence the area of shape C = 16 square units
Answer:
rectangle A's area: 12, 3 x 4 = 12
Area b: 1 x 4 = 4 divided by 2 = 2, the base is 1 height is 4. Multiply given lengths, then multiply by 1/2 because formula of a triangle is BH x 1/2. To get your answer of 2.
Area C: 3 + 5 = 8, 8 x 4 = 32, 32 divided by 2 = 16, formula of a trapezoid is base 1 + base 2 x height x 1/2. In this case 5 is your base and base 2 is 3. Add them up to get 8. We then multiply 8 by the height which is 4 if you count from the top to bottom in the middle. 8 x 4 = 32. 32 x 1/2 = 16 (basically just dividing by 2).

In order to ensure that the roof consists of right angles, an architect measures the diagonal to create a triangle. If the dimensions of the
triangle are 9.5 feet, 16 feet, and 18.5 feet, is the triangle a right triangle?
Answers
Answer:I have a question
Step-by-step explanation:
About that question is it a right triangle or no
The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the height of the triangle is AB = 16 feet
The base of the triangle is BC = 9.5 feet
The hypotenuse of the triangle is AC = 18.5 feet
And , for a triangle , if a² + b² > c² , it is an acute triangle
Substituting the values in the equation , we get
( 9.5 )² + ( 16 )² > ( 18.5 )²
90.25 + 256 > 342.25
346.25 > 342.25
Hence , the triangle is an acute triangle

Find the area of this figure.
Answers
Answer:
216 cm^2
Step-by-step explanation:
Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.
14 * 12 = 168
Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.
(8 * 12) / 2
96 / 2
48
Now, combine these two values to get the total:
168 + 48 = 216 cm^2
