what is the perimeter of the triangle?
what is the area or the triangle?
Answers
Answer:
Step-by-step explanation:
Answer:
Area = 7
Perimeter = 21 m
Step-by-step explanation:
Remark
The perimeter is just the sum of the three sides of the triangle.
The Area is the base * height /2
Givens
Perimeter: Three sides: 5 + 7 + 9
height: 2 meters
Formula
Area = 1/2 Base * Height
Area = 1/2 7 * 2
Note:
Just so you know the height should be almost 5. 2 is an impossible amount for the height.
Area = 1/2 * 7 * 2
Area = 7 m^2
Perimeter = 5 + 7 + 9
Perimeter = 21

There are 64 teams in a basketball tournament. All teams play in the
first round but only winning teams move on to subsequent rounds.
Write an explicit rule for T(n), the number of games in the nth round of
the tournament. State the domain:
Answers
The domain of this function is n ≥ 1, where n is the round of the tournament.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
The explicit rule for T(n), the number of games in the nth round of the tournament is 2ⁿ⁻¹. The domain of this function is n ≥ 1, where n is the round of the tournament.
Since all teams play in the first round, the number of games in the first round (n = 1) is 2¹⁻¹, which is equal to 1. As the rounds progress, the number of games in each round is doubled. T
herefore, the number of games in the second round (n = 2) is 2²⁻¹, which is equal to 2. The number of games in the third round (n = 3) is 2³⁻¹, which is equal to 4.
This pattern continues for each round, as the number of games in the nth round is 2ⁿ⁻¹.
Therefore, the domain of this function is n ≥ 1, where n is the round of the tournament.

For the past 40 days, Naomi has been recording the number of customers at her restaurant between 10:00 a.m. and 11:00 a.m. During that hour, there have been fewer than 20 customers on 25 out of the 40 days.
What is the experimental probability there will be **20 or more customers** on the forty-first day? Include it as fraction, decimal and percent.
Answers
Answer:
the experimental probability for 20 or more customersis 37.5%
Step-by-step explanation:
Given that
The recording of the customers would be in between 10:00 AM to 11:00 PM
In this, they have been fewer than 20 customers on 20 out of the 40 days
We need to find out the experimental probability for 20 or more customers
So,
= (40 - 25) ÷ (40)
= 15 ÷ 40
= 37.5%
Hence, the experimental probability for 20 or more customers is 37.5%

As reported in Trends in Television, the proportion of US households who have at least one VCR is 0.592. If 8 households are selected at random, without replacement, from all US households, what is the (approximate) probability that the number having at least one VCR is exactly 4. Be sure to use many decimal places in your calculations (at least 4), but report your answer to three decimal places.
Answers
Answer:
0.23825
Step-by-step explanation:
Given :
p = 0.592 ; number of trials, n = 8
x = 4 ; q = 1 - p = 1 - 0.592 = 0.408
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 4) = 8C4 * 0.592^4 * 0.408^4
P(x = 4) = 70 * 0.592^4 * 0.408^4
P(x = 4) = 0.23825
Find the distance using the modulus of the difference between z1 = -8 + 3i and z2 = 7 - 4i.
Answers
Answer:
[tex]d = 16.55[/tex]
Step-by-step explanation:
Given
[tex]z_1 = -8 + 3i[/tex]
[tex]z_2 = 7 - 4i[/tex]
Required
The distance between them
First, calculate the difference (d) between z1 and z2
[tex]d = z_1 - z_2[/tex]
[tex]d = -8 + 3i - [7 - 4i][/tex]
Open bracket
[tex]d = -8 + 3i - 7 + 4i[/tex]
Collect like terms
[tex]d = -8 - 7+ 3i + 4i[/tex]
[tex]d = -15+ 7i[/tex]
Using modulus, we have:
[tex]d = \sqrt{R^2 + I^2}[/tex]
Where
R = Real Part = -15
I = Imaginary Part = 7
So, we have:
[tex]d = \sqrt{(-15)^2 + 7^2}[/tex]
[tex]d = \sqrt{225 + 49}[/tex]
[tex]d = \sqrt{274}[/tex]
[tex]d = 16.55[/tex]

Potassium-42 has a half-life of 12.4 hours. How much of an 848 gram sample of potassium-42 will be left after 62.0 hours?
Answers
The required amount of potassium-42 left after 62.0 hours is 26.5 grams.
Given that,
Potassium-42 has a half-life of 12.4 hours. How much of an 848-gram sample of potassium-42 will be left after 62.0 hours is to be determined.
The half-life of the element is defined as the time span in which the element grows or decays half of its whole composition of growth and decay.
Here,
Amount left of the potassium after 62 hours is given as,
A = 848 [1 / 2 ] ⁶²/¹²°⁴
A = 26.5 gram
Thus, the required amount of potassium-42 left after 62.0 hours is 26.5 grams.
