A group of 20 people are going to run a race. The top three runners earn gold, silver, and bronze medals. How many outcomes are possible for these awards?
Answers
Answer:
There are 6,840 possible outcomes for these awards.
Step-by-step explanation:
Given that a group of 20 people are going to run a race, and the top three runners earn gold, silver, and bronze medals, to determine how many outcomes are possible for these awards, the following calculation must be performed:
20 x 19 x 18 = X
380 x 18 = X
6.840 = X
Therefore, there are 6,840 possible outcomes for these awards.
Total outcomes that are possible for these awards are 6840 outcomes, calculated using permutation.
Total number of people=20
what is the difference between permutation and combination?permutation means the arrangement of items while the combination is all about the selection of some out of many.
let us say start with the gold medal
no of ways a gold medal can be given = ²⁰C₁ = 20
Now, the number of people left is 19
no of ways a silver medal can be given = ¹⁹C₁ = 19
Now, the number of people left is 18
no of ways a bronze medal can be given = ¹⁸C₁ = 18
possibility of total outcomes=20*19*18 = 6840ways
Therefore, total outcomes that are possible for these awards=6840

Write the recursive formula for the sequence
37, 67, 97, 127, 157
Answers
Answer:
The recursive formula for this arithmetic sequence would be [tex]a_{1} = 37[/tex], [tex]a_{i} = a_{i-1} + 30[/tex].
Step-by-step explanation:
A recursive formula is a formula that defines each term of a sequence using the preceding term(s). Recursive formulas must always state the initial term, or terms, of the sequence, as well as an equation defining [tex]a_{i}[/tex] in terms of preceding terms. Since the first term of this sequence is 37, that means [tex]a_{1} = 37[/tex]. The pattern in this arithmetic sequence between each term in ascending order would be 30 more than the previous term, so you can create the function [tex]a_{i} = a_{i-1} + 30[/tex]. So the recursive formula for this arithmetic sequence would be [tex]a_{1} = 37[/tex] and [tex]a_{i} = a_{i-1} + 30[/tex].
A life guard in a tower 20 ft above sea level spots a struggling surfer at an angle of depression of 15 . How far is the surfer from the base of the tower?
Answers
Answer: [tex]19.31\ ft[/tex]
Step-by-step explanation:
Given
The tower is at a height of [tex]h=20\ ft[/tex]
the angle of depression is [tex]15^{\circ}[/tex]
Suppose the surfer is x ft away from the base of the tower
[tex]\therefore \text{From the figure, we can write}\\\\\Rightarrow \cos 15^{\circ}=\dfrac{x}{h}\\\\\Rightarrow x=h\cos 15^{\circ}\\\Rightarrow x=20\cos 15^{\circ}\\\Rightarrow x=19.31\ ft[/tex]
Therefore, the surfer is at a distance of 19.31 ft from the base of the tower.

now substitute x 12 is equal to 8 and check whether if it satisfies the given inequality.Putting x = 8

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
The number of red squares = 15
The number of blue squares = 35
Now , the total number of squares is N = 50 squares
a)
The ratio of red squares to blue squares is = number of red squares / number of blue squares
The ratio of red squares to blue squares is = 15 / 35
The ratio of red squares to blue squares is = 3 : 7
b)
The ratio of blue squares to total squares is = number of blue squares / total number of squares
The ratio of blue squares to total squares is = 7 : 10

For her birthday, Patty's parents gave her $5,000.00 which they put into a savings account that earns 10% interest compounded continuously. When Patty started college, she withdrew the entire balance of $5,789.00 and used it to pay for tuition. How long was the money in the account?
Answers
Answer:
1.465 years
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 per year,
Then, to solve for time t, when compound interest is compounded continuously, the formula is given as:
t = ln(A/P) / r
Where
A = Amount after time t = $5,789.00
P = Principal = Initial amount = $5,00
r = 0.1
Hence,
t = ln(5,789.00/5,000.00) / 0.1
t = 1.465 years
Therefore, the money was in the account for 1.465 years
