Naya [18.7K]
The probability of there being zero males is given by:
P(zero\ males)=4C0\times0.5^{0}\times0.5^{4}=\frac{1}{16}
Similarly the probability of there being zero females is also 1/16.
The probability there will be at least 1 male and 1 female is therefore:
1-(\frac{1}{16}+\frac{1}{16})=\frac{7}{8}
The answer is: 7/8.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?<br><br> –10<br> –5<br> –3<br> –1
givi [52]

Answer: -1

Step-by-step explanation:

Given by your question

2(3x-1)≥4x-6

Distributive property to take off the parentheses

2×3x-2×1≥4x-6

6x-2≥4x-6

Subtract 4x on both sides (Subtractive property of equality)

6x-2-4x≥4x-6-4x

2x-2≥-6

Add 2 on both sides (Addition property of equality)

2x-2+2≥-6+2

2x≥-4

Divide 2 on both sides (Division property of equality)

2/2 x≥-4/2

x≥-2

----------------------------------------------------------------------------

Looking at the options you've provided.

-10 INCORRECT, it is not greater or equal to -2

-5 INCORRECT, it is not greater or equal to -2

-3 INCORRECT, it is not greater or equal to -2

-1 CORRECT, it is greater than -2

Hope this helps!! :)

We can use ratios to solve

15 ft            18ft

---------- = -----------

5ft               x

Using cross products

15x = 5*18

15x = 90

Divide by 15

15x/15 = 90/15

x =6
