The number of hours, h, it takes for a block of ice to melt varies inversely as the temperature, t. If it takes 3 hours for a
square inch of ice to melt at 60 degrees, find the constant of proportionality
a. 150
c. 210
b. 180
d. 200
Answer:
180
Step-by-step explanation:
hours = constant / temperature hours varies inversely as the temperature
3 = c / 60
c (constant) = 3 * 60 = 180
Answer:
b. 180

Jay has an album that holds 700 compact discs. Each page of the album holds 7 compact discs. If
56% of the album is empty, how many pages are filled with compact discs?
Answer:
44 pages
Step-by-step explanation:
If it can hold 700 disks, with each page holding 7 disks, that means there are 100 pages in the album.
Since 56% of the album is empty, that means 56 pages are empty.
If 56 pages are empty, we can find how many pages are full by subtracting this from 100
100 - 56
= 44
So, 44 pages are full with compact discs

The triangles ΔABE and ΔDCE are congruent to each other by the SAS postulate. Then the correct option is B.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangles are ΔABE and ΔDCE.
In triangles ΔABE and ΔDCE
AE = EC (given)
∠AEB = ∠DEC (vertically opposite angles)
BE = DE (midpoint theorem)
The triangles ΔABE and ΔDCE are congruent to each other by the SAS postulate. Then the correct option is B.

Calculate the area of a triangle and correct to 2 significant figures.
Answer:
Area = 15 m²
Step-by-step explanation:
Given:
Triangle with two side lengths, 4 m and 10 m, and an included angle, 50°.
Required:
Area of the triangle
Solution:
Formula for calculating the area of a triangle with two sides and an included angle = ½*a*b*Sin C
a = 4 m
b = 10 m
C = 50°
Plug in the values into the equation
Area = ½*4*10*Sin 50°
Area = 20*Sin 50°
Area = 15.3208889
Area = 15 m² (to 2 s.f)

If f(x) = 3x+ 5 and g(x) = – 2x2 – 5x + 3, find (f + g)(x).
Answer: 1/8
Step-by-step explanation:(f÷g)(x) =
f(x) / g(x) =
2x / 22x
When we divide expressions with like bases, we subtract the exponents.
2(x - 2x) =
2-x
Now we substitute x = 3
So (f÷g)(3)
2-3
When we have a negative exponent, we perform the reciprocal of the expression and remove the negative sign from the exponent.
1/(23) =
1/8

Check whether the relation R on the set S = {1, 2, 3} is an equivalent
relation where:
= {(1,1), (2,2), (3,3), (2,1), (1,2), (2,3), (1,3), (3,1)}. Which of the
following properties R has: reflexive, symmetric, anti-symmetric,
transitive? Justify your answer in each case?
Answer:
[tex]R[/tex] isn't an equivalence relation. It is reflexive but neither symmetric nor transitive.
Step-by-step explanation:
Let [tex]S[/tex] denote a set of elements. [tex]S \times S[/tex] would denote the set of all ordered pairs of elements of [tex]S\![/tex].
For example, with [tex]S = \lbrace 1,\, 2,\, 3 \rbrace[/tex], [tex](3,\, 2)[/tex] and [tex](2,\, 3)[/tex] are both members of [tex]S \times S[/tex]. However, [tex](3,\, 2) \ne (2,\, 3)[/tex] because the pairs are ordered.
A relation [tex]R[/tex] on [tex]S\![/tex] is a subset of [tex]S \times S[/tex]. For any two elements[tex]a,\, b \in S[/tex], [tex]a \sim b[/tex] if and only if the ordered pair [tex](a,\, b)[/tex] is in [tex]R\![/tex].
A relation [tex]R[/tex] on set [tex]S[/tex] is an equivalence relation if it satisfies the following:
Reflexivity: for any [tex]a \in S[/tex], the relation [tex]R[/tex] needs to ensure that [tex]a \sim a[/tex] (that is: [tex](a,\, a) \in R[/tex].)Symmetry: for any [tex]a,\, b \in S[/tex], [tex]a \sim b[/tex] if and only if [tex]b \sim a[/tex]. In other words, either both [tex](a,\, b)[/tex] and [tex](b,\, a)[/tex] are in [tex]R[/tex], or neither is in [tex]R\![/tex].Transitivity: for any [tex]a,\, b,\, c \in S[/tex], if [tex]a \sim b[/tex] and [tex]b \sim c[/tex], then [tex]a \sim c[/tex]. In other words, if [tex](a,\, b)[/tex] and [tex](b,\, c)[/tex] are both in [tex]R[/tex], then [tex](a,\, c)[/tex] also needs to be in [tex]R\![/tex].The relation [tex]R[/tex] (on [tex]S = \lbrace 1,\, 2,\, 3 \rbrace[/tex]) in this question is indeed reflexive. [tex](1,\, 1)[/tex], [tex](2,\, 2)[/tex], and [tex](3,\, 3)[/tex] (one pair for each element of [tex]S[/tex]) are all elements of [tex]R\![/tex].
[tex]R[/tex] isn't symmetric. [tex](2,\, 3) \in R[/tex] but [tex](3,\, 2) \not \in R[/tex] (the pairs in [tex]\! R[/tex] are all ordered.) In other words, [tex]3[/tex] isn't equivalent to [tex]2[/tex] under [tex]R\![/tex] even though [tex]2 \sim 3[/tex].
Neither is [tex]R[/tex] transitive. [tex](3,\, 1) \in R[/tex] and [tex](1,\, 2) \in R[/tex]. However, [tex](3,\, 2) \not \in R[/tex]. In other words, under relation [tex]R\![/tex], [tex]3 \sim 1[/tex] and [tex]1 \sim 2[/tex] does not imply [tex]3 \sim 2[/tex].

Answer:
[tex]VW = 50[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find VW
To find VW, we make use of the following equivalent ratios.
[tex]YX : XW = ZX : XV[/tex]
Where:
[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]
[tex]XV = XW + VW = 25 + VW[/tex]
So, we have:
[tex]14 : 25 = 42 : 25 + VW[/tex]
Express as fraction
[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]
Divide both sides by 14
[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]
Cross multiply
[tex](25 + VW) * 1 = 3 * 25[/tex]
[tex]25 + VW = 75[/tex]
Solve for VW
[tex]VW = 75 -25[/tex]
[tex]VW = 50[/tex]

To pass the time on his travels, Ibn Battuta decides to run a test to see if the mean caravan size passing through a certain outpost is greater than 20 camels. He records the sizes of 7 caravans that pass through, assume that this represents a simple random sample of all caravans. After noticing that a smaller number of caravans are significantly larger than the rest of the population, he concludes the population is quite different from normal. He does not know the population's standard deviation. Which of the following describe which kind of test he should run?
a. He should run a Z-test.
b. He should run a T-test, and approximating it with a normal distribution would be appropriate.
c. He should run a T-test, and approximating it with a normal distribution would be inappropriate.
d. None of the above would be appropriate tests.
In the given scenario, one can use only non-parametric tests as the distribution is not normal.
Statistically speaking, normality means the distribution of data or variables following a normal distribution, also known as a Gaussian distribution or bell curve.
a. Since the standard deviation of the population is not known, Z-test cannot be run.
b. According to the thumb rule, for approximation to normality by using the central limit theorem, the minimum sample size is required to be 30.
With a sample size of 7, normality cannot be assumed.
So, a t-test with approximating the distribution with normal distribution would not be appropriate to run.
c. Without normality assumptions, one can't run a t-test because the t-test's basic assumption is the normality of the distribution.
So, all the options are incorrect which leaves us with the option d. None of the above would be appropriate tests.
