Answer:
5 units
Step-by-step explanation:
We can use the formula for finding the length or magnitude of line joining two points.
Length = √((x2-x1)² + (y2-y1)²)
The points joining the line are C (-1,4) and D (2,0)
Length = √((2+1)² + (0-4)²)
= √((3²) + (-4)²)
= √ (9+16)
= √25
= 5 units
Answer:
The answer is x=−1247
Step-by-step explanation:
Let's solve your equation step-by-step.
1+39(12−44)=x
Step 1: Simplify both sides of the equation.
1+39(12−44)=x
1+−1248=x
(1+−1248)=x(Combine Like Terms)
−1247=x
−1247=x
Step 2: Flip the equation.
Answer: x=−1247
Answer:
{-2, 6}

Answer:
n = -26
Step-by-step explanation:
Move the constant to the right and calculate
The conditional relative frequency for female students who prefer playing sports is 34%.
<h3>How to determine the statistic calculated?</h3>
The table of values is given as:
Sports Dancing Row totals
Male students 18 16 34
Female students 18 35 53
Column totals 36 51 87
Mason's calculation is given as:
P = 21%
This is gotten by
18/87 = 21%
The above represents the joint relative frequency of female students who prefer playing sports.
To calculate the conditional relative frequency, he should divide 18 by the row total.
So, we have
18/53 = 34%
Hence, the conditional relative frequency for female students who prefer playing sports is 34%.
