Answer:
264.4375
Step-by-step explanation:
Surface area of a box = 2(lw + lh + wh)
L = 8 , W = 1.75 and H = 12.125
==> plug in values
SA = 2((8)(1.75) + (8)(12.125) + (1.75)(12.125))
==> multiply values that are inside parenthesis together
SA = 2(14 + 97 + 21.21875)
==> add values inside of parenthesis
SA = 2(132.21875)
==> multiply 2 and 132.21875
SA = 264.4375in²

In a recent poll, 18% of seniors said they will attend the upcoming prom. Twenty seniors chosen at random were asked if they plan to attend the prom. What is the probability that at most 5 seniors will attend the prom?
Question 3 options:
0.136
0.149
0.758
0.864
Using the binomial distribution, it is found that there is a 0.864 = 86.4% probability that at most 5 seniors will attend the prom.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
18% of seniors said they will attend the upcoming prom, hence p = 0.18.Twenty seniors chosen at random were asked if they plan to attend the prom, hence n = 20.The probability that at most 5 seniors will attend the prom is given by:
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.18)^{0}.(0.82)^{20} = 0.0189[/tex]
[tex]P(X = 1) = C_{20,1}.(0.18)^{1}.(0.82)^{19} = 0.0829[/tex]
[tex]P(X = 2) = C_{20,2}.(0.18)^{2}.(0.82)^{18} = 0.1730[/tex]
[tex]P(X = 3) = C_{20,3}.(0.18)^{3}.(0.82)^{17} = 0.2278[/tex]
[tex]P(X = 4) = C_{20,4}.(0.18)^{4}.(0.82)^{16} = 0.2125[/tex]
[tex]P(X = 5) = C_{20,5}.(0.18)^{5}.(0.82)^{15} = 0.1493[/tex]
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0189 + 0.0829 + 0.1730 + 0.2278 + 0.2125 + 0.1493 = 0.864[/tex]

write algebraic expressions to represent the following:
a) the sum of x and y b) the product of m and 7
c) the cost of 3 movie tickets at m dollars each d) 3 less than n, all divided by 4
Answer:
a) x + y
b) m x 7 or 7m
c) m x 3 or 3m
d) [tex]\frac{n - 3}{4}[/tex]
Step-by-step explanation:
a) the sum of x and y
- the sum most likely always means addition
b) the product of m and 7
- the product usually means multiplucation
c) the cost of 3 movie tickets at m dollars each
- so your getting 3 movie tickets at $m
the total would be m + m + m which is the same as mutiplying m by 3
d) 3 less than n, all divided by 4
- 3 less than n
less than usually means subtraction
than divided by 4

First, "the sum of" indicates that we add.
Since we're asked to find the sum of x and y, we need to add them:-
x+yNow, the "product of" indicates that we multiply.
So we multiply m times 7, which can be written as follows:-
7mIf we have 3 movie tickets, and each of them costs m dollars, then in order to find the cost of all 3 movie tickets, we need to find the product of the total number of tickets times the cost of one ticket:-
So we multiply 3 times m, or
3mNow, "3 less than n" indicates that we subtract 3 from n; this expression is divided by 4, or:-

What value of X will make line 1 parallel to line 2
A. 32
B.58
C.72
D.148
Answer:
Step-by-step explanation:
Remark
The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20 must equal 52. That's all you have to do. Just equate the 2 givens and solve.
Givens
x - 20 is one angle
52 is the other.
Solution
x - 20 = 52 Add 20 to both sides.
x - 20 + 20 = 52 +20 Combine
x = 72

An airport in Death Valley is 60 feet below sea level, and an airplane is flying at 2000 feet above sea level.
How many feet must the plane descend in order to land?
A.2060
B.2000
C.1940
D.1880
E.1400
Answer:
A
Step-by-step explanation:
Sea level is defined as 0 ft and anything above or below is not sea level so
So . .
If the landing strip is 60 feet below sea level and the plane is flying 2000 feet above sea level just add them together
60 + 2000 =2060According to attachment

AB+AC2000+602060ftThe perimeter of a rectangle is 48 feet, and the length is 16 feet. what is the area?
Answer: [tex]128ft^2[/tex]
Step-by-step explanation:
If the 16ft is the sum for both sides already means the first length is 8ft and also the second length is 8ft. then since there are 32 ft more left, you divide it by two since there were two widths left, the values of the two widths are 16ft each. so the sum of the two widths is 32ft. and that's the final answer.
[tex]Length=16[/tex]
[tex]Perimeter=48[/tex]
[tex]Using ~the ~formulas:[/tex]

Answer:
4 < n < 130.
Step-by-step explanation:
n is a positive integer
n^100 > 2^200
2^2*100 = 2^200
4 ^100 = 2^200
So n > 4
(130n)^50 > n^100
130^50 * n^50 > n^100
130^50 > n^50
130 >n
so n < 130.

-4(x-4)=-44
Please answer this with how you got the answer.
Answer: x = -15
Step-by-step explanation:
Think PEMDAS
First, we factor the parenthesis:
-4 (x-4) = -4(x) + -4(-4)
now we are left with -4x + 16 = -44
Next is to isolate the "x":
to do this, we must subtract 16 from -44
-44 - 16 = 60
now we have -4x = 60
Now we divide both sides by -4 in order to isolate "x"
dividing -4x/-4 = x
diving 60/-4 = -15
the answer is x= -15

does someone mind helping me with this question? Thank you!
Answer:
I dont mind :D These were my favorite! They are actually really simple. Dont overthink it. It even gave you a hint!
It says a^2 + b^2 = c^2
We can substitute what we do have which is a = 10 and c = 15
10^2 + b^2 = 15^2
Now we square it
100 + b^2 = 225
Next, all we have to do is subtract the 100 from our answer so 225-100 which is 125, so b has to be 125!!! Because 125 + 100 is 225 :D
Step-by-step explanation:
The length of "b" using Pythagoras Theorem.
Solution:[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {10}^{2} + {b}^{2} = {15}^{2} [/tex]
[tex]b = {15}^{2} - {10}^{2} [/tex]
[tex] {b}^{2} = 125[/tex]
[tex]b = \sqrt{125} [/tex]
[tex]b = 11.18033989[/tex]
[tex]b = 11.2 \: (nearest \: tenth)[/tex]
Therefore, the length of "b" is 11.2

Explanation:
3(2x+2)= 4x -10
apply distributive method: a(b+c) = ab + ac
3(2x) + 3(2) = 4x - 10
multiply
6x + 6 = 4x - 10
subtract both sides by 4x
6x + 6 - 4x = 4x - 10 -4x
simplify
2x + 6 = -10
subtract both sides by 6
2x + 6 -6 = -10 -6
simplify
2x = -16
divide both sides by 2
