A map has a scale of 3 cm:20 km. If two cities are 30 cm apart on a map, how far are the cities actually apart?
The actual distance between the cities is 200 km using multiplication.
The scale of the map is 3 cm : 20 km. This means that for every 3 cm on the map, the actual distance in real life is 20 km.
If two cities are 30 cm apart on the map, we can use the scale to find the actual distance between them. First, we need to determine how many times the scale goes into the distance on the map. To do this, we divide the distance on the map by the length of the scale:
30 cm ÷ 3 cm/20 km = 30 ÷ 3 × 20 = 200 km
Therefore, the actual distance between the two cities is 200 km.
Alternatively, we can use the proportionality between the scale and the actual distance to set up a proportion and solve for the actual distance. Let x be the actual distance between the cities in kilometers:
3 cm / 20 km = 30 cm / x
Cross-multiplying and solving for x, we get:
x = (20 km / 3 cm) × 30 cm = 200 km

Step-by-step explanation:
A thief steals an atm card and must randomly guess the correct five-digit pin code from a 8-key keypad. repetition of digits is allowed. what is the probability of a correct guess on the first try?
Answer:
The probability of a correct guess on the first try is 0.024%.
Since a thief steals an atm card and must randomly guess the correct four -digit pin code from a 8 -key keypad, and repetition of digits is allowed, to determine what is the probability of a correct guess on the first try the following calculation must be performed:
8 x 8 x 8 x 8 = X
8 ^ 4 = X
4096 = X
1/4096 = X
0.000244140625 = X
0.000244140625 x 100 = 0.024%
Therefore, the probability of a correct guess on the first try is 0.024%
Step-by-step explanation:
Out of 100 people sampled, 36 had kids. Based on this, construct a 95% confidence interval for the true
population proportion of people with kids.
Give your answers as decimals, to four places
This is the same as saying 0.2659 < p < 0.4541
=========================================================
Work Shown:
At 95% confidence, the z critical value is about z = 1.96 which is determined through a table or calculator.
x = number of people who had kids = 36
n = sample size = 100
phat = sample proportion of those who had kids
phat = x/n
phat = 36/100
phat = 0.36
E = margin of error
E = z*sqrt(phat*(1-phat)/n)
E = 1.96*sqrt(0.36*(1-0.36)/100)
E = 0.09408
This value of E is approximate because z = 1.96 is approximate.
-------------
L = lower bound
L = phat - E
L = 0.36 - 0.09408
L = 0.26592
L = 0.2659
U = upper bound
U = phat + E
U = 0.36 + 0.09408
U = 0.45408
U = 0.4541
The values of L and U are approximate since E is approximate.
-------------
The confidence interval in the format (L, U) is (0.2659, 0.4541)
This is equivalent to writing 0.2659 < p < 0.4541
which is the format L < p < U
We're 95% confident that the true population proportion (p) is somewhere between 0.2659 and 0.4541; i.e. we're 95% confident the true percentage of people who had kids is somewhere between 26.59% and 45.41%

The yearly median income for a female with an associate degree would be $27,744.
What is the weekly median income for a female with an advanced degree?An advanced degree would be a postgraduate degree like a masters so the weekly median income would be $901.
What is the yearly median income for a male with an associate degree?This can be found as:
= Weekly median income x 4 weeks in month x 12 months in year
= 759 x 4 x 12
= $36,432
What is the yearly median income for a female with an associate degree?= Weekly median income x 4 weeks in month x 12 months in year

Part I: Suppose a prism has a square base with each side of length 3.75 cm and a height
of 5.65 cm. Use the formula below to find the volume. Show your work and round your
answer to the nearest hundredth. (5 points)
79.45401²
Step-by-step explanation:[tex]1)\ V=B\ Sh[/tex]
[tex]\therefore\ V=3.15\times 3.75\times 5.65[/tex]
[tex]=79.403125[/tex]
[tex]\approx 79,45\ cm^3[/tex]
I hope this helps you
:)
Rounded to the nearest hundredth, the volume of the prism is approximately 79.50 cm^3.
To find the volume of a prism, we use the formula:
Volume = Base Area * Height
In this case, the prism has a square base with each side of length 3.75 cm and a height of 5.65 cm. The formula for the area of a square is:
Base Area = Side Length^2
So, the base area can be calculated as:
Base Area = 3.75 cm * 3.75 cm = 14.0625 cm^2
Now, we can find the volume using the formula:
Volume = Base Area * Height
Volume = 14.0625 cm^2 * 5.65 cm
Volume ≈ 79.5025 cm^3

An oblique cylinder with a base of radius 2 units is shown. The top
of the cylinder can be obtained by translating the base by the directed line segment
AB which has length 16 units. The segment AB forms a 30° angle with the plane of
the base. What is the volume of the cylinder?
The volume of the cylinder is the amount of space on it
The volume of the oblique cylinder is 174.19 cubic units
How to determine the volume of the cylinder?The given parameters are:
AB = 16 units
Radius (r) = 2 units
[tex]\theta = 30^o[/tex]
Start by calculating the height (h) using:
[tex]h = 16 * \cos(30^o)[/tex]
This gives
[tex]h = 13.86[/tex]

A high-altitude spherical weather balloon expands as it rises due to the drop in atmospheric pressure. Suppose that the radius r increases at the rate of 0.03 inches per second and that r=48 inches at time t=0. Determine a function that models the volume V of the balloon at time t and find the volume at t=300 seconds.
Considering a linear function for the radius, we have that:
The volume of the sphere is modeled by [tex]V(t) = \frac{4\pi(0.03t + 48)^3}{3}[/tex].After 300 seconds, it is of 775,735 in³.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.What is the volume of a sphere?The volume of a sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this problem, radius r increases at the rate of 0.03 inches per second and that r=48, hence it is represented by the following linear function:
[tex]r(t) = 0.03t + 48[/tex]
Thus, the volume of the sphere is given by:
[tex]V = \frac{4\pi r(t)^3}{3}[/tex]
[tex]V(t) = \frac{4\pi(0.03t + 48)^3}{3}[/tex]
After 300 seconds, the volume in cubic inches is given by:
[tex]V(300) = \frac{4\pi(0.03(300) + 48)^3}{3} = 775735[/tex]

To find out how many games will be played with 10 people, we need to first find the pattern of the given table. To start out, we can see that for the numbers of players added, it adds one each time it goes up one number. And, we can also see that starting at 1 games played, it adds 2 for the next and gets 3 games. Then it adds 3 to get 6 games. So, we can see that for every added person added, it starts at 1 and adds 2, then adds, 3, 4, 5, 6, etc... Knowing this, we can figure out how many games will be played with 10 people.
2 people gets 1 games
+1 +2
3 people get 3 games
+1 +3
4 people get 6 games
So, now we can simply skip to 6 and seven players becuase we know that the pattern holds true to itself.
6 people get 15 games
+1 +6
7 people get 21 games
+1 +7
8 people get 28 games
+1 +8
9 people get 36 games
+1 +9
10 people get 45 games
