Caroline has a unique pet chimpanzee that is relatively likely to have twins. Each pregnancy is independent, and
mrs_skeptik [129]

Answer: 2=.36, 3=.48, 4=.16

Step-by-step explanation:

If we let "S" represent 1 baby and "D" represent 2 babies, the sample space for the chimpanzee's 2 pregnancies is {SS, SD, DS, DD}.

We can find the probability of each possible outcome by multiplying the probability of the independent events leading to that outcome.

Outcomes:. Probability:

SS. .60 x .60 = .36

SD. .60 x .40 = .24

DS. .40 x .60 = .24

DD. .40x .40 =.16

Total. 1.00

Lastly group the similar outcomes. SD+DS= .48

Give an example of a polynomial that is a perfect square. How do you know that it is a perfect square? Give its factored form.
lora16 [44]

Answer:

Step-by-step explanation:

A polynomial is a  perfect square if has the form:

a^2+2ab+b^2

Its factored form is  (a+b)^2.

We can obtain examples by taking any value of a and b.

For example:

a=x  anb  b=2y.  

Thus we obtain a polynomial that is a perfect square:

x^2+2(x)(2y)+(2y)^2=x^2+4xy+4y^2

Ram can travel 20km by a motorcycle in 1 litre of petrol.how far can he travel from 5 litres of petrol?Also,how much petrol will
raketka [301]

Answer:

On 5 liters of petroleum he can go 100km.

He needs 37.5 liters of petroleum to go 750km.

Step-by-step explanation:

He goes 20km on 1 liter. Now we must find how far he can go on 5 liters.

1 * 5 = 5

20 * 5 = 100

The reason we multiplied was because we had to multiply 1 by 5 to get the number of liters of petroleum and what you to one side you must do to the other.

To find how many liters are needed to go 750km you must divide:

750/20 = 37.5

He needs 37.5 liters of petroleum to travel 750km.

Hope this helps! :)

Find the value of x. Give reasons to justify your solution. b ∈ ac, d ∈ fa
tatiyna

Answer:

x = 27

Step-by-step explanation:

∠ ABD and ∠ BDE are alternate angles and are congruent, then

∠ BDE = 72°

∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is

2x + 72 + 2x = 180

4x + 72 = 180 ( subtract 72 from both sides )

4x = 108 ( divide both sides by 4 )

x = 27
