Answers
Considering the values of each digit, the expressions that have the same values as 30,452 are given by:
C. 30,000 + 400 + 50 + 2.
D. thirty thousand, four hundred fifty-two
What are the values of the digits in a number?We start at the final digit, the unit digit, with value 1, and moving to left, each digit has a value multiplied by 10.
Hence, for number 30,452, we have that:
Digit 2 has a value of 1.Digit 5 has a value of 10.Digit 4 has a value of 100.Digit 0 has a value of 1000.Digit 3 has a value of 10,000.Hence the number, multiplying each digit by it's value, can be written as:
C. 30,000 + 400 + 50 + 2.
The number is also read as:
D. thirty thousand, four hundred fifty-two

The data below represent the per capita (average) disposable income (income after taxes) for 25 randomly selected cities in a recent year.

Frequency distribution allows finding the occurrence of events: 12, 9, 0, 1
The frequency distribution is a grouping of data in exclusive categories, where the number of occurrences of each event is indicated
In this case the categories and their occurrences are
Categories Occurrence Frecuencie relative (%)
30,000 - 36,000 12 54.5%
36000 - 42000 9 40.9%
42000 - 48000 0 0%
48000 - 54000 1 4.5%
With these data, bar graphs can be built where the category is placed on the x-axis, an independent variable, and the occurrences on the y-axis, a dependent variable.
With these distributions, relative frequency is defined, which is the number of times a category appears among the total number of events.
fr = occurrence /n
Where fr is the relative frequency and n is the number of events, sometimes it is given as a percentage by multiplying by one hundred
In this case the number of events is n = 22
Category 30000- 36000
fr₁ = 12/22
fr₁ = 0.5454
fr₁% = 54.5%
Category 36000 - 42000
fr₂ = 9/22
fr₂ = 0.4090
fr₂% = 40.9%
Category 42000-48000
fr₃ = 0
fr₃% = 0%
Category 48000 - 54000
fr₄ = 1/22
fr₄ = 0.04545
fr₄% = 4.5%
The frequency distribution allows finding the occurrence of the events:

The mass of the eggs laid by a certain breed of hen is a normally distributed random variable with mean 0.06kg and standard deviation 0.009kg. If a random sample of 1800 eggs are sold, how many would you expect to have mass; (i)Less than 0.052 kg (standard size). (ii)Between 0.052 kg and 0.075kg (medium size).(iii)Greater than 0.075 kg (large size).
(b)If the cost of producing an egg in (a) is Gh¢0.45 and selling price of each standard, medium and large size eggs are Gh¢0.60, Gh¢0.80, and Gh¢0.95 respectively, calculate (i)The expected profit to be made from selling the standard size, medium size and large size eggs. (ii)The overall profit.
Answers
a (i) The number of standard size is 288 eggs
a (ii) The number of medium size is 1,476 eggs
a (iii) The number of large size is 36 eggs
b (i) The expected profit made from selling the standard size is Gh¢43.2
b (ii) The expected profit made from selling the medium size is Gh¢516.6
b (iii) The expected profit made from selling the large size is Gh¢16.2
The given parameters:
the mean of the distribution, m = 0.06 kg
standard deviation (std) of the distribution, d = 0.009 kg
number of the samples, n = 1800 eggs
(i) Find the position of "less than 0.052 kg (standard size)":
1 standard deviation below the mean = m - d m - d = 0.06 kg - 0.009 kg = 0.051 kg(the standard size is 1 standard deviation below the mean)
less than 1 standard deviation below the mean in a normal distribution is equal to 16% of the data samplesNumber of standard size = 0.16 x 1800 = 288 eggs(ii) Find the position of "Between 0.052 kg and 0.075kg (medium size)":
0.052 kg is 1 standard deviation below the mean2 standard deviation above the mean = m + 2dm + 2d = 0.06 + 2(0.009) = 0.078 kg(the medium size is between 1 std below the mean and 2 std above the mean)
Between 1 std below the mean and 2 std above the mean in a normal distribution = (68 + 14)% = 82%Number of medium size = 0.82 x 1800 = 1,476 eggs(iii) Find the position of "Greater than 0.075 kg (large size)":
0.078 kg is 2 standard deviation below the meangreater than 2 std above the mean in a normal distribution = 2 % of the data samples Number of large size = 0.02 x 1800 = 36 eggsCheck: 288 eggs + 1476 eggs + 36 eggs = 1,800 eggs
(b) the cost of production of an egg = Gh¢0.45
the selling price of the standard size = Gh¢0.60
the selling price of the medium size = Gh¢0.80
the selling price of the large size = Gh¢0.95
(i) The expected profit made from selling the standard size:
Profit = total revenue - cost of production
Profit = 288(0.6) - 288(0.45) = Gh¢43.2
(ii) The expected profit made from selling the medium size:
Profit = total revenue - cost of production
Profit = 1476(0.8) - 1476(0.45) = Gh¢516.6
(iii) The expected profit made from selling the large size:
Profit = total revenue - cost of production
Profit = 36(0.9) - 36(0.45) = Gh¢16.2

One angle of a triangle measures 136º. The other two angles are congruent.
Enter and solve an equation to find the measure x of the congruent angles.
Answers
Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°

Sam glued 21 identical cubes together to form the solid shown below. He painted the exposed faces of the solid including the base. Find the total area that Sam painted.
Answers
Answer:
[tex]3456\; \rm cm^{2}[/tex].
Step-by-step explanation:
The diagram suggests that the length of a row of five cubes is [tex]40\; \rm cm[/tex]. Hence, the length of the edge of each cube would be:
[tex]\displaystyle \frac{40\; \rm cm }{5} = 8\; \rm cm[/tex].
That would correspond to an area of [tex](8\; \rm cm)^{2} = 64\; \rm cm^{2}[/tex] for each face of the cube.
Refer to the diagram attached.
Viewing from the front and from the rear each shows [tex]11[/tex] faces of the cubes.
Viewing from the top and from the bottom each shows [tex]10[/tex] faces of the cubes.
Viewing from the left and from the right each shows [tex]6[/tex] faces of the cubes.
When viewed from the six perspectives, [tex]2 \times 11 + 2 \times 10 + 2 \times 6 = 54[/tex] faces of the cubes are visible in total.
For this particular construction, all faces that need to be painted are visible when viewed from exactly one of the six perspectives: front, rear, top, right, left, right. Hence, Sam would need to paint [tex]54[/tex] of such [tex]64\; \rm cm^{2}[/tex] squares.
The area that Sam needs to paint would be [tex]54 \times (64\; \rm cm^{2}) = 3456\; \rm cm^{2}[/tex].

answer is not an integer, express it as a decimal.
Answers
Answer:

Step-by-step explanation:
Slope = (change in y) / (change in x) = (y₂-y₁)/(x₂-x₁)
We have two points on the graph, (2, 16) and (6, 48)
Let's say (2, 16) = (x₁, y₁) ( there's no reason why (6, 48) can't be (x₁, y₁), but one of them has to be it) and (6, 48) = (x₂, y₂). Our slope is then
(y₂-y₁)/(x₂-x₁) = (48-16) / (6-2) = 32 / 4 = 8
