Step-by-step explanation:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.
In the example, what is the relationship between the perimeter and the side length of an equilateral triangle
Answer:
P = 3s
Step-by-step explanation:
To start with, let's assume that
The perimeter of a triangle is called P
The side of a triangle is called s
Now, by formulae, the perimeter of an equilateral triangle is given as P = 3s. Which is the same as adding up the 3 sides together.
Succinctly put, we can then conclude that if P = 3s, then the perimeter of an equilateral triangle is equal to the lengths of its 3 sides.

Which pair of functions are inverse of each other
Answer:
(A)
Step-by-step explanation:
(14,-1),(5,7) slope
Answer:
(-9, 8)
Step-by-step explanation:
(14, -1) >> (x1, y1)
(5, 7) >> (x2, y2)
(y2 - y1) 7 - (-1) = 8
----------- >>>
(x2 - x1) 5 - 14 = -9

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given function is f(x) = 13-5x/4. The value of the expression will be calculated as below:-
E = 13-5x/4
Put the value of x equal to 1.
E = 13-5/4
E = 47-5/4
E = 1/4
Therefore, the value of the expression is (1/4).

What is Mortgage Rate?A mortgage rate is the interest rate on a mortgage. Mortgage rates are set by the lender and might be fixed, remaining constant during the length of the loan, or variable, varying with a benchmark interest rate. Borrowers' mortgage rates differ depending on their credit profile.
We have,
P = $105, 000
T = 40 year
R = 5.2%
Using
Monthly payment, P = C[i(1+i[tex])^n[/tex]]/[(1+i[tex])^n[/tex]-1]
P = 105,000 [ 0.052/12(1+0.052/12[tex])^{480[/tex]]/[(1+0.052/12[tex])^{480\\[/tex]-1]
P = 105,000 [ 0.00433 (7.8426)] / [7.8426 -1]
P = 105,000 [ 0.03372318] / (6.8426)
P = $249,739

At a certain fire station, false alarms are received at a mean rate of .2 per day. In a year, what is the probability that fewer than 60 false alarms are received?
Answer:
0.064
Step-by-step explanation:
Number of days in a year = 365
Mean rate of false alarm in a year = λ = 365 * 0.2 = 73
Standard deviation, σ = sqrt(λ) = sqrt(73) = 8.54 (for large λ value)
Using the relation :
P(x < 60): (60 - 73) / 8.54
P(x < 60) = - 1.52
P(Z < - 1.52) = 0.06426 (Z probability calculator

A bike tire has a diameter of 35 inches. If the tire rotates 10 revolutions, how far did the bike travel?
Answer:
Distance travelled = 91.61 feet
Step-by-step explanation:
Given the following data;
Diameter, d = 35 inches
Number of revolutions = 10 Rev
To find the distance travelled by the bike;
First of all, we would determine the circumference of the bike's tire, which is circular in shape.
Circumference of circle = πd
Circumference of circle = 35π
Next, we multiply by the number of revolutions to get the distance travelled.
Distance travelled = 35π * 10
Distance travelled = 350π inches
But pie, π = 3.142
Distance travelled = 350 * 3.142
Distance travelled = 1099.7 inches.
In feet;
1 inches = 0.0833 feet
1099.7 inches = x feet
Cross-multiplying, we have;
x feet = 1099.7 * 0.0833
x feet = 91.61 feet
Distance travelled = 91.61 feet

The depth of accumulated snow is [tex]d=10\ in.[/tex]
Snow is melting at the rate of [tex]r=0.5\ \text{in. per hour}[/tex]
Time taken for complete melting of snow is

A dilation maps (4, 6) to (2, 3). Under the same dilation, (-1, 3) would be mapped to _____. (-1/2, 3/2) (-3, 0) (-2, 6)
Answer:
(-1/2, 3/2).
Step-by-step explanation:
A dilation maps (4, 6) to (2, 3).
4/2 = 2, 6/3 = 2
It means that each coordinate is divided by 2.
(-1, 3) would be mapped to

To find the height of a pole, a surveyor moves 121 feet away from the base of the pole and then, with a transit 3.6 feet tall, measures the angle of elevation to the top of the pole to be 39. To the nearest foot, what is the height of the pole? Round your final answer to the nearest tenth of a foot.
Answer: 139 feet
Step-by-step explanation:I used tan. Tan(44) = x/140
x = 140(Tan 44)
x = 135.196
The transit is 4, so we add that to 135.
This makes 139 feet.
