It would be helpful to see the actual choices, but let me try to answer anyway:

(1) blue area:

y>=4*x+1

read area

y<-3

(2) blue:

y>3*x-3

red:

y <= 0.5*x + 2

Assume each newborn baby has a probability of approximately 0.53 of being female and 0.47 of being male. For a family with four

Vitek1552 [10]

Answer:

0.3723

Step-by-step explanation:

Since the number of girls = X

Probability of girls p = 0.53

Probability of boys q = 0.47

Number of observation n = 4

A) conditions for binomial distribution are

1: The number of observations n must be fixed.

2: Each observation is independent. 3: Each observation represents one of two outcomes ("success" or "failure").

B) for the question n = 4

p (probability of success for girls) = 0.53

C) n=4, r (number of trials) = 2

Using binomial expansion

4C2 *(p)² *(q)² = 6* (0.53)² * (0.47)²

= 0.3723

Therefore, the probability of the family having two boys and two girls is 0.3723.

. Let f(x) = x2 and g(x) = x − 3. Evaluate (g ∘ f)(−2). 1 7 20 −20

lesya692 [45]

For this case we have the following functions:

$f (x) = x ^ 2\\g (x) = x-3$

We must find $(g_ {0} f) (x)$

By definition we have to:

$(g_ {0} f) (x) = g (f (x))$

So:

$g (f (x)) = (x ^ 2) -3 = x ^ 2-3$

We must evaluate the composite function for $x = -2$

$g (f (-2)) = (- 2) ^ 2-3 = 4-3 = 1$

ANswer:

$g (f (-2)) = 1$
