<h2>Answer:</h2>

The constraint which represent a thriving population of penguins at the zoo is:

            0 < x ≤ 10   and   0 < y ≤ 20.

<h2>Step-by-step explanation:</h2>

Let x = the number of female penguins and y = the number of male penguins.

Now, it is given that:

The group needs two times more males than females to thrive, and the zoo only has room for 10 female penguins.

This means that:

   0 < x ≤ 10

( Because there are no room for more than 10 penguins )

Also,

   y= 2x

Since,

   x>0

This means that: 2x>0

i.e. y>0

and x ≤ 10

i.e. 2x ≤ 20

i.e.  y ≤ 20

Hence, the constraints which represent a thriving population of penguins at the zoo is:

                 0 < x ≤ 10 and 0 < y ≤ 20.

A midpoint divides a line segment into two congruent segments. So, if point U is the midpoint of RS, then that means that RU and SU are congruent.

If RU is 12, then SU is also 12.

So, the whole length of SR is 24.

1) Solution: 24

The midpoint and segment congruency statement in the first problem also applies to the second problem.

SV = TV

2x = 11

Divide both sides by 2 to get x by itself.

x = 5.5

2) Solution: 5.5

Suppose that a pregnancy test kit, while tested on women, produces 95% true positive and 90% true negative. Suppose that 7% of w
satela [25.4K]

Answer:

0.5885

Step-by-step explanation:

The possible ways for a test to be positive are:

- Woman is pregnant & true positive

- Woman is not pregnant & false positive

The probability of a positive is:

P(+) = 0.07*0.95+(1-0.07)*(1-0.95)\\P(+)=0.113

Therefore, the probability that a woman is actually pregnant given that she tested positive is:

P(P|+) = \frac{0.95*0.07}{0.113}\\P(P|+) = 0.5885

The probability is 0.5885
