What is the length of one side of a cube that has a surface area of 1,734 square mm?
Answer:
a = 17
Step-by-step explanation:
1,734 = 6a^2
1,734/6 = 6a^2/6
[tex]\sqrt{289}[/tex] = [tex]\sqrt{a^2}[/tex]
a = 17
Answer:
side = 17 mm
Step-by-step explanation:
1734/6 = 289
√289 = 17 mm

Which set of ordered pairs represents y as a function of x?
Answer:
D is the correct answer
Explanation:
the following function satisfies each output to its input for the set D
f(x)=x/2
let's check each pair:
0/2=0
-1/2=-0.5
-2/2=-1
-3/2=-1.5
-4/2=-2
the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)
- in A x=-1 | y=2, -2 and this wrong
- in B x=3 | y=9, 16 and this wrong
- in C x=0 | y=0, 1 and this wrong

44 students decided to take a cupcake, and 33 of them picked vanilla. What percentage of the students picked
Answer:
33.33%
Step-by-step explanation:
Given data
Total number of students= 44
Number of students that picked vanilla= 33
Therefore the percentage that picked vanilla is
=44-33/44*100
=11/33*100
=0.3333*100
=33.33%
Hence the percentage is 33.33%

A couple decides to keep having children until they have a girl, at which point they will stop having children. They also agree to having a maximum of three children. The table below shows the probability distribution of X=, equals the number of children such a couple would have.
X=# of children 1 2 3
P(X), .5 .25 .25
Given that \mu_X=1.75μ
X
=1.75mu, start subscript, X, end subscript, equals, 1, point, 75 children, find the standard deviation of the children such a couple would have.
Round your answer to two decimal places.
\sigma_X\approxσ
X
≈sigma, start subscript, X, end subscript, approximately equals
children
Answer:.83
Step-by-step explanation:
Khan academy
From the discrete distribution given, the standard deviation is of 0.83 children.
The distribution is:
[tex]P(X = 1) = 0.5[/tex]
[tex]P(X = 2) = 0.25[/tex]
[tex]P(X = 3) = 0.25[/tex]
The mean is 1.75.The standard deviation is the square root of the sum of the difference squared between each value and the mean, multiplied by it's respective probability.Hence:
[tex]\sqrt{V(X)} = \sqrt{0.5(1 - 1.75)^2 + 0.25(2 - 1.75)^2 + 0.25(3 - 1.75)^2} = 0.83[/tex]
The standard deviation is of 0.83 children.

Isabella has 63 hair bows. Isabella's sister has h more hair bows than Isabella. Choose the expression that shows how many hair bows Isabella's sister has.
Answer:
(h+63)
Step-by-step explanation:
Given that,
Isabella has 63 hair bows.
Isabella's sister has h more hair bows than Isabella. It means,
Isabella's sister = h+63
h and 63 are added as Isabella's sister has h more hair bows than Isabella.
Hence, the expression would be (h+63).

A helicopter flew north 325 meters and then flew east 500 meters. How far is the helicopter from its starting point?
Answer:
596.34m approx
Step-by-step explanation:
Given data
Let the Starting point be x
A helicopter flew north 325 meters from x
Then flew east 500 meters
Let us apply the Pythagoras theorem to solve for the resultant which is the distance from the starting position
x^2= 325^2+500^2
x^2=105625+250000
x^2= 355625
x= √355625
x=596.34m
Hence the distance from the starting point is 596.34m approx

Hey there!
To find the area of a square, multiply the side length by itself, also known as sqaring the side length.
We must solve 3/5 x 3/5.
3/5 x 3/5 = 0.36
The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.
Your final answer is 0.36 .
Hope this helps!
