7 0

Answer:

Step-by-step explanation:

Inequality given for Sara,

-4(2x + 4) > 8x + 64

-8x - 16 > 8x + 64

-8x - 8x > 16 + 64

-16x > 80

-x > 5

x < -5

x = -12 will be the answer.

Option (3)

Inequality for Alezandro,

7x + 20 ≥ 2(x - 15)

7x + 20 ≥ 2x - 30

7x - 2x ≥ -30 - 20

5x ≥ -50

x ≥ -10

Therefore, x = 2 is the answer.

Option (2)

For Daria,

3(x - 17) < 9(1 - 3x)

3x - 51 < 9 - 27x

3x + 27x < 51 + 9

30x < 60

x < 2

x = -6 will be the answer.

Option (1)

For Jamal,

5(x + 11) > -4(-x - 12)

5x + 55 > 4x + 48

5x - 4x > 48 - 55

x > -7

x = 10 will be the answer.

Option (4)

a family has five children. the probability of having a girl is 1/2. whats probability of having at leasr 4 girls g'
Dima020 [189]

Answer:

Probability of having at least 4 Girls

= 0.6875

Step-by-step explanation:

Probability of having at least 4 Girls is 1-probability of having exactly 3 girls

Total number of children= 5 = N

Probability of having a girl p = 0.5

Probability of not having a girl q= 0.5

X= 3

Probability of at least 4 girls is given by

Probability= NCX(p)^x(q)^(N-x)

Probability = 5C3(0.5)^3(0.5)^(5-3)

Probability = 5C3(0.5)^3(0.5)^2

Probability= 5!/3!2!(0.5)^3(0.5)^2

Probability= 10(0.125)(0.25)

Probability= 0.3125

Probability of having at least 4 Girls

= 1- 0.3125

= 0.6875

Which graph represents y= square root x?​
Arada [10]
<h2>Answer:</h2>

y=\sqrt{x} is the square root function. The graph of this function has been attached below. As you can see, this is in fact a function it passes the Vertical Line Test for Functions that establishes that if a vertical line intersects a graph at most one point, then this is a function. From the square root function we know:

  • The domain of the function is the set of all nonnegative real numbers.
  • The range of the function is the set of all nonnegative real numbers.
  • The origin (0,0) is an intercept of the graph.  
  • The graph increases on the interval (0, \infty).
