Answer:
-4 , -1
Step-by-step explanation:
( -4 is the X- axis [ the horizontal line] and 1 is the y-axis [the vertical line] ) move ur finger to -4 on the left and go up to 1. Now move ur finger down 2 times . ur finger will be on -4 which is the x- axis and -1 for the y - axis
So,
Let Mercado's age be m and his daughter's age be d.
Our first equation: m = 37
Our second equation: m = 5 + 4d
Substitute 37 for m
37 = 5 + 4d
Subtract 5 from both sides
32 = 4d
Divide both sides by 4
8 = d
His daughter is 8 years old.
Hello there! the answer would be x = 3/4.
You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.
4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).
4x - 1x + 4 = 8 - Combine like terms.
3x + 4 = 8 - Subtract 4 from both sides.
3x = 4 - divide both sides by 3.
x = 3/4. This is your final answer.
I hope this was helpful, have a great day! :)
Answer:
10.63
Step-by-step explanation:
Data provided in the question
Data = 30 subjects
The Variance of scores = 113.00
The calculation of standard deviation is shown below:-
As we know that
Variance = Standard deviation^2
Therefore,
Standard deviation = 
= 
= 10.63
Therefore for computing the standard deviation we simply applied the above formula.
The area of the square is 9 in^2
The side of a square is the square root of the area.
Side of square = √9 = 3 inches.
The side of the square is the diameter of the inscribed circle.
Circumference of a circle is PI x diameter.
Circumference of inscribed circle = 3.14 x 3 = 9.42 inches
The diameter for the circumscribed circle would be the diagonal of the square which is 3√2 = ( Side length x √2) ≈ 4.2426
The circumference = 3.14 x 3√2 = 13.321
Find the ratio between the two circles:
Circumscribed / inscribed =
13.321 / 9.42 = 1.41
