Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don't have to be together.
The solution to 6×+2y=6 is y=0.5
The solution for 7×+3y=5 is y
= 0.238095 (.238095 is repeated)
A discrete variable is a type of variable which contains a finite number of values. It usually takes its values from the set of whole numbers.
From the random variable described, the random variable that is descrete is "You measure the maximum heart rate in beats per minute".
This is because, heart rate cannot be partitioned it only takes counting number values. You either have 1 beat per minutes, 2 or 3 and so on beats per minute. But you cannot have 2.5 or 3.8 and so on beats per minute.
So heart rate cannot take decimal or fractional values and hence, it is a discrete random variable.
Answer:
answer: 9
Step-by-step explanation:
Assuming this is the Pythagorean theorem the formula is a²+ b² = c² so we arent given a but we are given c so we have to work backwards c = 15 and 15 × 15 = 225 12 × 12 = 144 225 - 144 = 81 so Now we just have to figure out what multiplied by itself equals 81 therefore 9 is our answer because 9 × 9 = 81 Hope that helps!
Answer:
- 45
Step-by-step explanation:
let n be the number , then
n - 11 = n + 4 ( add 11 to both sides )
n = n + 15 ( multiply through by 3 to clear the fraction
2n = 3n + 45 ( subtract 2n from both sides )
0 = n + 45 ( subtract 45 from both sides )
- 45 = n
The number is - 45
