Step-by-step explanation:
1. Approach
The surface area is the two-dimensional space around a three-dimensional object. In other words, if one was going to wrap an object with paper, the surface area is the amount of paper one would need. To find the surface area, one could find the area of each face of the prism and then add up all of the values.
2. Finding the surface area,
To find the area of each face of the prism, one must multiply the length of the face by the width of the face. After doing so, add up all of the resulting values.
10 * 20 = 200
8 * 20 = 160
6 * 20 = 120
[tex]\frac{1}{2}[/tex] * 6 * 8 = 24
[tex]\frac{1}{2}[/tex] * 6 * 8 = 24
Add up all of the values,
200 + 160 + 120 + 24 + 24
= 528

If 500 births were observed rather than only 5, what is the approximate probability that at least 490 do not result in birth defects
Answers
Answer:
Probability that at least 490 do not result in birth defects = 0.1076
Step-by-step explanation:
Given - The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC). A local hospital randomly selects five births and lets the random variable X count the number not resulting in a defect. Assume the births are independent.
To find - If 500 births were observed rather than only 5, what is the approximate probability that at least 490 do not result in birth defects
Proof -
Given that,
P(birth that result in a birth defect) = 1/33
P(birth that not result in a birth defect) = 1 - 1/33 = 32/33
Now,
Given that, n = 500
X = Number of birth that does not result in birth defects
Now,
P(X ≥ 490) = [tex]\sum\limits^{500}_{x=490} {^{500} C_{x} } (\frac{32}{33} )^{x} (\frac{1}{33} )^{500-x}[/tex]
= [tex]{^{500} C_{490} } (\frac{32}{33} )^{490} (\frac{1}{33} )^{500-490}[/tex] + .......+ [tex]{^{500} C_{500} } (\frac{32}{33} )^{500} (\frac{1}{33} )^{500-500}[/tex]
= 0.04541 + ......+0.0000002079
= 0.1076
⇒Probability that at least 490 do not result in birth defects = 0.1076

Area = 150.5*sqrt(3)Perimeter = 57+7*sqrt(3)Approximate Answers:
Area = 260.673646539Perimeter = 69.12435565======================================
Explanation:
Your diagram is 100% correct. Nice work.
To get the area of the trapezoid, we could use the area of a trapezoid formula below:
A = h*(b1+b2)/2
In this case, we have,
h = 7*sqrt(3) = heightb1 = 18 = base1b2 = 25 = base2the bases are parallel to each other. The height is always perpendicular to the base. We won't use the "14" at all.
So,
A = h*(b1+b2)/2
A = 7*sqrt(3)*(18+25)/2
A = 7*sqrt(3)*21.5
A = (7*21.5)*sqrt(3)
A = 150.5*sqrt(3)
This is the exact area.
The approximate area is roughly
150.5*sqrt(3) = 260.673646539
The units for the area are in square km, or km^2. Though your teacher said for you not to include the units.
Another way to get the area of the trapezoid is to break the diagram into a rectangle and triangle as you have done so, and then find the area of each sub-piece. Adding the two smaller areas should lead to the result shown above.
-----------------------------------
To get the perimeter, we add up all of the exterior sides. We do not include the right-most vertical line that is 7*sqrt(3) km long because it is inside the figure. The horizontal segment that is 7 km long is part of the "25 km" segment, so we'll ignore that 7.
Adding the four exterior sides leads to:
7*sqrt(3)+18+14+25 = 57+7*sqrt(3)
This value is exact. It approximates to
57+7*sqrt(3) = 69.12435565
The units for the perimeter are in kilometers, and you won't have any exponent over the "km". While your teacher doesn't want the units, it's still handy to know what the units would be.
Step-by-step explanation:
solution given:
for rectangle
length [l]=18km
breadth [b]=7√3 km
for triangle
base[b1]=25-18=7km
height [h]=b=7√3km
for area :area of. (rectangle +triangle}=
l×b+1/2 b1×h=18×7√3+1/2 ×7×7√3=260.67km²
now
perimeter=sum of all sides
=18+14+25+7√3=69.12km

Step-by-step explanation:
The exact quotient is 876.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
21,900 / 25

Using long division,

Line of reflection → x = 1
Step-by-step explanation:
Coordinates of B → (3, 2)
Coordinates of B' → (-1, 2)
If point B is reflected across a vertical line x = a, both the points B and B' will be equidistant from the line of reflection.
Coordinates of the midpoint of the segment joining B and B'
= [tex](\frac{x_+x_2}{2},\frac{y_1+y_2}{2})[/tex]
= [tex](\frac{3-1}{2},\frac{2+2}{2})[/tex]
= (1, 2)
Line of reflection will pass through this midpoint (1, 2)
Therefore, equation of the line of reflection will be,

Answer: A
Step-by-step explanation:
I just took the USATESTPREP quiz and that is the answer.
Option (C) will define the changes in the graph of the function with the values of 'd'.
Given function in the question → y = alog(x + c) + d
Rules for the translation of a function,
If a function y = f(x) is shifted 'h' units upwards on y-axis, rule for the translation will be → y = f(x) + hIf the function y = f(x) is shifted 'h' units downwards, rule for the translation → y = f(x) - hHence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.
And for the negative value of 'd' will define the shift of the function downwards.
Option (C) will be the correct option.
