Answer:
4
Step-by-step explanation:
1. Find the Mean
(8+12+15+17+18)/5=14
2.For each number, subtract the Mean and square the result.
(8-14)^2=36
(12-14)^2=4
(15-14)^2=1
(17-14)^2=9
(18-14)^2=16
3. Find the Mean of those squared differences.
(36+4+1+9+16)/5=13.2
4.Take the square root of that and this is what you want.
square root of 12.7 = 3.6 (round up to 4)
Answer:
x =5
Step-by-step explanation:
6 + 8 ( x - 1) = 2 (3x + 4)
Distribute
6+8x-8 = 6x+8
Combine like terms
8x -2 = 6x +8
Subtract 6x from each side
8x-6x -2 = 6x -6x+8
2x -2 =8
Add 2 to each side
2x-2 +2 = 8+2
2x = 10
2x/2 = 10/2
x =5
Answer:
cos = adjacent of angle A / hypotenuse
Step-by-step explanation:
cos = adjacent of angle A / hypotenuse . . . . . . . . . . . .
Let's say the Height of the triangle is 4 cm., the Base is 3 cm, and the Hypotenuse is 5 cm. If the top angle was angle A then the value would be 4/5. Because the Height is adjacent to angle A and the Hypotenuse is 5 cm.
The rational number is equivalent to 0.36 is 9/25
<h3>How to determine the equivalent rational number?</h3>
From the question, we have the following decimal number that can be used in our computation:
Decimal number = 0.36
To start with, we need to express the decimal number as a fraction
This is represented as follows:
So, we have the following representation
Decimal number = 36/100
Change the label of the above representation to rational number
Rational number = 36/100
Simplify the rational number (divide the numerator and the denominator by 2)
Rational number = 18/50
Simplify the rational number (divide the numerator and the denominator by 2)
Rational number = 9/25
Hence, the equivalent rational number is 9/25

It's a linear function in slope-intercept form (y = mx + b)
f(x) = 4 - 4x = -4x + 4
m = -4, b = 4.
Domain of a linear function is the set of all real numbers.
Range of a linear function where m ≠ 0 is the set of all real numbers.
