A certain city has a population of about 100,000. There are 3,101 people with red hair in the city. Which of these is closest to the probability that a randomly selected person in the city has red hair?
Answer:
3%
hope this helps!
Step-by-step explanation:
The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.
The required probability can be calculated by dividing the number of people with red hair by the total population of the city:
= 3,101 / 100,000
= 0.03101,
It can be rounded to 0.03.
Thus, the required probability is 0.03.

Step-by-step explanation:
Two mechanics worked on a car. The first mechanic charged $115 per hour, and the second mechanic charged $65 per hour. The mechanics
combined total of 15 hours, and together they charged a total of $1475. How long did each mechanic work?
Answer:
Here is another case where we have two unknowns (the number of hours each mechanic worked) so we'll need two equations to solve.
Let A = number of hours first mechanic worked (the one who charged $45/hour)
Let B = number of hours second mechanic worked (the one who charged $105/hour)
From the problem statement, we know that the two mechanics worked a combined 35 hours so the first equation is:
Equation 1: A hours + B hours = 35 hours
We also know that in total, the charge was $2475. So the second equation is:
Equation 2: (A hours x 45 dollars/hour) + (B hours x 105 dollars/hour) = 2475 dollars
So our two equations are:
1: A + B = 35
2: 45A + 105B = 2475
Multiply both sides of the first equation by -45 to get the following:
-45A - 45B = -1575
Now the two equations are:
1: -45A - 45B = -1575
2: 45A + 105B = 2475
Add them together and the "A" term drops out:
-45B + 105B = -1575 + 2475
or
60B = 900
Now divide both sides by 60:
B = 15
Now plug B = 15 into the first equation:
A + 15 = 35 thus A = 20
So Mechanic A (at $45/hour) worked 20 hours and Mechanic B (at $105/hour) worked 15 hours
Check: 20x45 + 15x105 = 900 + 1575 = 2475

Classify the polynomial according to its degree and number of terms.
9
constant monomial
sixth-degree monomial
linear binomial
sixth-degree binomial
Answer:
constant monomial
Step-by-step explanation:
The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here given expression is 9.
A constant monomial is a term with only a constant number. There is no variable in a constant monomial.
So, 9 is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.

- El resultado de la conversión de 350 km/h a m/s es:
A. 1.26x10 m/s
B. 1260 m/s
C. 97.22 m/s
Answer:
350 kilómetros por hora son 97,2222 metros por segundo ;)
The result of converting 350 km/h to meter per second is 97.22 m/s.
To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.
The conversion factor for this conversion is 1 km/h = 0.2778 m/s.
To convert 350 km/h to m/s, multiply 350 by the conversion factor:
350 km/h×0.2778 m/s
= 97.22 m/s
Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.

27=15+n I can not get this one ether
Answer:
n= 12
Step-by-step explanation:
27=15+n
step 1. simplify
27=n+15
step 2. flip the equation n+15=27
step 3. subtract 15 from both sides
n+ 15 - 15 = 27 - 15 =
n=12
Answer:
12.
Step-by-step explanation:
We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.

Part B
Using the linear equation, predict the average height for a two-year old.
A. 15 inches
B. 22 inches
C. 31 inches
D. 35 inches
Answer:
(a) [tex]y = 4.5x + 22[/tex] -- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,22)[/tex]
[tex](x_2,y_2) = (4,40)[/tex]
So, we have:
[tex]m = \frac{40 - 22}{4 - 0}[/tex]
[tex]m = \frac{18}{4}[/tex]
[tex]m = 4.5[/tex]
The equation is then calculated using:
[tex]y = m(x-x_1)+y_1[/tex]
Where:
[tex](x_1,y_1) = (0,22)[/tex]
[tex]m = 4.5[/tex]
[tex]y = 4.5(x - 0) + 22[/tex]
Open bracket
[tex]y = 4.5x - 0 + 22[/tex]
[tex]y = 4.5x + 22[/tex]
(b) The height of a 2 year old.
To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]
[tex]y = 4.5 * 2 + 22[/tex]
[tex]y = 9+ 22[/tex]
[tex]y = 31[/tex]

EF = DE = 67
base = 31
Step-by-step explanation:
For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:
For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:
12x – 22 = 10x – 6 = 7x + 18
Instead of using all three at once, you can use any two. I'll be using:
12x – 22 = 10x – 6
2x = 16
x = 8
Plugging x in, we can get all the sides, because this is an equilateral triangle:
12x – 22
12(8) – 22
96 – 22
74
For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:
8x – 13 = 5x + 17
3x = 30
x = 10
Plugging in x for one of the congruent sides and the base, you can get your needed side length values:
8x – 13
8(10) – 13
80 – 13
67
x + 21
10 + 21

Rearrange t= 5s + 4 to make s the subject
Answer:
Subject 's' in terms of 't'
[tex]s = \frac{t-4}{5}[/tex]
Step-by-step explanation:
Explanation:-
Given that the subject 't in terms are 's'
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
[tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]
[tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]
[tex]s = \frac{t-4}{5}[/tex]
