P(all 4 are male) = 1/2^4 = 1/16 ( assuming probability of 1 male = 1/2)

P( 3 are male) = 1/2^4*4 = 1/4

The rest will have at least 2 females

So probability of at least 2 females) = 1 - 1/16 - 1/4 = 1 - 5/16 = 11/16 answer

PLEASE HELP!!

Vikentia [17]

Answer:

Part a) The inequality that represent the situation is

$x+(3x)+(6x) \leq 350\ in$

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

$x+(3x)+(6x) \leq 350$

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

Solve the inequality

$x+(3x)+(6x) \leq 350$

$10x \leq 350$

Divide by 10 both sides

$x \leq 35\ in$

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$

The variable x varies directly as y and x varies inversely as z. What is the value is y when x=20 and z=-2, if y=30 when z=3 and

miv72 [106K]

Answer:

Y=-80

Step-by-step explanation:

X=Ky/z

5=30k/3

30k=15

K=1/2

20=Ky/(-2)

Ky =-40

1/2y=-40

Y=-80
