A box 10 centimeters high, 5 centimeters long, and 5 centimeters wide.Find the volume of a box with a length of 5 cm, a width of 5 cm, and a height of 10 cm.
Answer:
250 [tex]cm^{3}[/tex]
Step-by-step explanation:
First, start with the formula for the volume of a rectangular prism (aka a box):
V=length*width*height
Then, plug in your values:
V=5*5*10
V=25*10
V=250

Find the probability that -5 ≤x≤5
The correct answer is 0.3
Given as:X : -10 -5 0 5 10 15 20
P(X)=f(x): 0.20 0.15 0.05 0.1 0.25 0.1 0.15
To find:probability of -5≤x≤5
Solution: ∑f(x)= f(-5)+f(0)+f(5)⇒ P(-5≤x≤5) = 0.15 +0.05+0.1 = 0.3
Hence, the answer of the given question is 0.3.

The expected value if I have to pick one package given the price I would have to pay is $0.11.
What is the expected value?The expected value is the cost you would have to pay subtracted from the total value of one package.
Total value of one package =[ (15 x 0.60) + (5 x 0.3) + (20 x 0.7)]/ (20 + 15 + 5) = $0.61

Julia made a model of a square pyramid. She used cardboard to construct the model with the dimensions shown. It has an open bottom.
A square pyramid has a square base with side lengths of 8 centimeters, and 4 triangular sides with a height of 5 centimeters.
What is the surface area of the model?
A. 80 cm2
B. 144 cm2
C. 224 cm2
D. 320 cm2
Answer:
A. 80 cm²
Step-by-step explanation:
If a square pyramid has an open base, then the surface area is made up of the 4 congruent triangular sides only.
Area of a triangle = 1/2 × base × height
Given:
Base = 8 cmHeight = 5 cm⇒ Area of one triangular face = 1/2 × 8 × 5
= 20 cm²
⇒ Total surface area = 4 triangular faces
= 4 × 20
= 80 cm²

find the hypotenuse of the triangle thats 3 and 7
pythagorean
3 squared + 7 squared
16 + 49 = 57
√57 is the hypotenuse
√57 is also the base of the triangle that has side thats 9
pythagorean theorem
x squared + √57 squared = 9 squared
x^2 + 57 = 81
x^2 = 81 - 57
x^2 = 24
x = √24
x = √4 * √6

An 80-centimeter ramp connects the sidewalk to the bed of a truck. If the ramp
forms a 30-degree angle with the ground, the truck bed is centimeters off the ground.
The truck bed is 40cm .
What is a right-angled triangle?A right-angled triangle is a triangle with one of its angle 90°.
Analysis:
The ramp, the height of the truck bed from ground and the distance of truck bed to the point the ramp makes contact with the ground form a right angle triangle.
So that sin 30 = height of truck bed above ground/length of ramp
sin 30 = height/80
height of the truck = 0.5 x 80 = 40cm

At each point (x, y) on a graph of function f, the graph has a slope equal to 4x - 4. If the
graph of f goes through the point (2, 3), then f(x) =
A)
2x² - 4x - 4
B)
2x² - 4x
C)
2x² - 1
D)
2x² - 4x + 3
E)
16x - 12
Answer:
f(x)= 2x² - 4x + 3
Step-by-step explanation:
dy/dx = 4x - 4
y = integrate dy/dx
y = 4x²/2 - 4x + c
y = 2x² - 4x + c
at (2,3)
3 = 2(2)² - 4(2) + c
3 = 8 -8 + c
c = 3
therefore f(x)= y = 2x² - 4x + 3
The graph of the function is given by f ( x ) = 2x² - 4x + 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
At each point (x, y) on a graph of function f, the graph has a slope equal to 4x - 4
So , dy/dx = 4x - 4
On integrating , we get
f ( x ) = 2x² - 4x + c
where the function passes through P ( 2 , 3 )
So , 3 = 2 ( 2 )² - 4 ( 2 ) + c
c = 3
Hence , the function is f ( x ) = 2x² - 4x + 3
