Answer:
You must divide
by 
Step-by-step explanation:
we have

Step 1
Solve for x


Step 2
Find the value of y

Substitute the value of x


therefore
You must divide
by 
Since there are 22 participants all in all. The possible combinations of the two picked for practice first is,
22C2 = 231
The probability of picking one from each gender will be solved through the calculation below.
(10C1)x(12C1) / 231 = 40/77
In percentage, the answer would be approximately 52%. Thus, the answer is the first choice.
Answer:
the length of ST = 3.6 to the nearest tenth
Step-by-step explanation:
Points on the Cartesian are written as (x, y)
Given points S(-4, -2) and T(-1, 0)
The distance between these two points is given by the formula
ST = √[(x₂-x₁)² + (y₂-y₁)²]
x₂ = -4
x₁ = -1
y₂ = -2
y₁ = 0
ST = √{[-4 - (-1)]² + [-2 - 0]²}
ST = √[(-4 + 1)² + (-2)²]
ST = √(-3²+4)
ST = √(9 + 4)
ST = √13
ST = 3.6 to the nearest tenth
2x2 + 3x = –5? 2x^2+3x+5 =0
300 with a remainder of 10
3 0 0
1 4 | 4 2 1 0
4 2
1 0
Therefore, 4210 / 14 = 300 with a remainder of 10.
300 with a remainder of 10
