In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00. Find the probability of winning if you pick the number 30 and it comes up on the wheel. Round your answer to 3 decimal places. Answer:
Answer:
Step-by-step explanation:
Total out come is 38
Favorable outcome is 1
Probability is 1/38 ≈ 0.026
The probability of winning if you pick the number 30, and it comes up on the wheel, will be 0.026.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00.
Then the total number of the event will be
Total event = 38 {0, 00, 1, 2, …, 36}
Then the probability of winning if you pick the number 30, and it comes up on the wheel will be
Favorable event = 1 {30}
Then the probability will be
P = 1 / 38
P = 0.026

The value of two integers are -3 and 7.
Here,
Given that;
The product of two integers is -21.
The difference between the integers is -10.
The sum of the two integers is 4.
We have to find the value of two integers.
What is integers?
An integers is a whole number (not a fractional number) that can be positive, negative, or zero.
Now,
Let two numbers are x and y.
Then, The product of two integers is -21.
x * y = -21 ..... (i)
The difference between the integers is -10.
x - y = -10 ..... (ii)
The sum of the two integers is 4.
x + y = 4 .....(iii)
Add equation (ii) and (iii), we get;
x - y + x + y = -10 + 4
2x = -6
x = -3
And,
x + y = 4
-3 + y = 4
y = 7
Hence the two integers x and y are -3 and 7.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that a linear model of this situation contains the values (1, 7.3) and (9, 9.7), where [x] represents the number of weeks, and [y] represents the baby's weight, in pounds.
Assume the equation of the line in slope - intercept form is -
y = mx + c
Now -
m = (9.7 - 7.3)/(9 - 1)
m = 2.4/8
m = 0.3
The equation will be -
y = 0.3x + c
For the point - (1, 7.3), we can write -
7.3 = 0.3 x 1 + c
c = 7.3 - 0.3
c = 7
Therefore, the baby's weight at the birth of the baby was 7 pounds.

A 5.1-ft-tall person walks away from a 12-ft lamppost at a constant rate of 3.9 ft/sec. What is the rate that the tip of the person's shadow moves away from the lamppost when the person is 9 ft away from the lampost?
Answer:
6.78ft/sec
Step-by-step explanation:
From the question, dx/dt= 3.9 ft/sec
We are looking for Dy/dt
From geometry,vof this case the relationship between x and y is needed here, there is two similar triangle that exhibited by the man and the lamb
12/y= 5.1/(y-x)
Then ,cross multiply, we have
12(y-x)=5.1y
12y-12x=5.1y
12y-5.1y=12x
6.9y=12x
y=( 12/6.9)x
Differentiating implicitly the bother sides with respect to t, we have
Dy/dt= ( 12/6.9)dx/dt
But dx/dt= 3.9 ft/sec
Then Dy/dt= ( 12/6.9)× 3.9
Dy/dt=6.78ft/sec
Hence, the rate that the tip of the person's shadow moves away from the lamppost when the person is 9 ft away from the lampost is 6.78ft/sec

Given that;
The graph is shown in figure.
And, The point z = (6 + 10i)
The point w = (1 + i)
Now,
We can find the value of z/w is,
⇒ z/w = (6 + 10i) / (1 + i)
= (6 + 10i) (1 - i) / (1 + i) (1 - i)
= (6 - 6i + 10i - 10i²) / (1 - i²)
= (6 + 4i + 10) / (1 + 1)
= (4i + 16) / 2

George borrowed $6,500 from the bank. 5 years later, George owes the bank $7,800.
What was the percentage rate of simple interest on the loan?
Answer:
Rate of simple interest = 4%
Step-by-step explanation:
Formula for simple interest is;
A = P(1 + rt)
Where;
P is principal
r is rate
t is time
Now, we are told that he borrowed $6,500 from the bank and that 5 years later, he owes the bank $7,800.
This means;
P = 6500
t = 5 years
A = 7800
Thus;
7800 = 6500(1 + 5r)
7800/6500 = 1 + 5r
1.2 = 1 + 5r
Subtract 1 from both sides to get;
1.2 - 1 = 1 - 1 + 5r
0.2 = 5r
r = 0.2/5
r = 0.04 or 4%

TO BE SHARED AMONG
HER SON AND THREE
DAUGHTER EACH DAUGHTER
SHARE WAS 3/4 OF THE SOn
SHARE
How much DID SON RECIEVED
Answer:
The son received 2,615.38.
Step-by-step explanation:
In order to know how much the son received, it is best to use algebraic expressions in finding the children's individual shares.
Let x be the son's share and [tex]\frac{3x}{4}[/tex] be the share of each daughter.
The equation will be: 8,500 = x + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex]
Next step is: 8,500 = [tex]\frac{3x+3x+3x+4x}{4}[/tex]
8,500 = [tex]\frac{13x}{4}[/tex]
8,500 × 4 = 13x
34,000 = 13x
[tex]\frac{34,000}{13}[/tex] = x
x = 2,615.38
The son received 2,615.38
Let's get the share of each daughter:
[tex]\frac{3x}{4}[/tex] = [tex]\frac{(3)(2,615.38)}{4}[/tex] = 1,961.54
Each daughter will receive 1,961.54
Let's check: 2,615.38 + 1,961.54 + 1,961.54 + 1,961.54 = 8,500
