Since there are 8 possibilities, but only one of them results in 3 tails tosses, the answer would be 1/8. 1 chance out of 8 possibilities.
Try this suggested solution:
1. if 'Equation2'-'Equation1', then
(5x+4y)-(5x-y)=42-27; ⇒ 5y=15; ⇒ <u>y=3</u>.
2. if to substitute y=3 into the Equation1, it is possible to find 'x':
5x-3=27; ⇒ 5x=30; ⇒ <u>x=6</u>.
answer: (6;3)
Answer:
radius: 4√(2π)/π "four times the square-root of two pi, over pi"
Step-by-step explanation:
The formula for area of a circle is
A = πr², where A is the area, π is the constant value pi, and r is the radius
We are given an area of 32 m² and need to find the radius, so we have...
32 = πr²
First, divide by π to get the r term by itself
32/π = r²
Now take the square root of both sides...
√(32/π) = r
Simplify the left side, you can distribute the square root to the numerator and the denominator...
(√32)/(√π) = r
√32 breaks down into 4√2 using a factor tree. You can't have a square root in the denominator so multiply top and bottom by √π
[(4√2)(√π)]/[(√π)(√π)] = r
This simplifies to
4√(2π)/π
Answer:
5(6x-1)
Step-by-step explanation:
Step 1 Subtract the numbers:
6x[3+(4-2)]-10+5
6x[3+(2))]-10+5
Step 2 Add the Numbers:
6x[3+2]-10+5
6x[5]-10+5
Step 3 Multiply the Numbers:
6x*5-10+5
30x-10+5
So the answer is 5(6x-1).
