alex41 [277]
Procedure:

1) calculate the number of diferent teams of four members that can be formed (with the ten persons)
2) calculate the number of teams tha meet the specification (two girls and two boys)
3) Divide the positive events by the total number of events: this is the result of 2) by the result in 1)

Solution

1) the number of teams of four members that can be formed are:

10*9*8*7 / (4*3*2*1) = 210

2) Number of different teams with 2 boys and 2 girls = ways of chosing 2 boys * ways of chosing 2 girls

Ways of chosing 2 boys = 6*5/2 = 15
Ways of chosing 2 girls = 4*3/2 = 6

Number of different teams with 2 boys and 2 girls = 15 * 6 = 90

3) probability of choosing one of the 90 teams formed by 2 boys and 2 girls:

90/210 = 3/7

if the measurements given are 333333 and 656565 then to find the diagonal length. we can use the Pythagorean theorem.
333333^2 + 656565^2 = x
take the square root of 333333^2 + 656565^2 to get 736334.49

Please help with trend lines
satela [25.4K]

Answer:

K=-2J+24

Step-by-step explanation:

Trend line passes through the points (6,12) and (4,16).

Find the slope of the line:

m=\dfrac{K_2-K_1}{J_2-J_1}=\dfrac{16-12}{4-6}=\dfrac{4}{-2}=-2

Write the equation of the line in the form K=mJ+b, where the slope m=-2:

K=-2J+b

This line passes through the point (6,12), then its coordinates satisfy the equation:

12=-2\cdot 6+b\\ \\12=-12+b\\ \\b=12+12\\ \\b=24\\ \\K=-2J+24
