Answer:

2/15

Step-by-step explanation:

Step one:

given data

sample space

1 elephant,

4 bears,

3 cats, and

2 dogs.

sample size= 1+4+3+2= 10

Required:

By selecting without replacement, the probability that she chooses a bear both times

Step two:

the first event= Pr(bear)= 4/10= 2/5

the second event, the sample size is now 9 and the number of bears is now 3

Pr(bear)= 3/9= 1/3

Hence, the probability that she chooses a bear both times

= 2/5*1/3

=2/15

There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

A_{surf}=2\times(l \times w)+2\times(l \times h)+2\times(h \times w)
A_{surf}=2\times(5\times7)+2\times(5\times12)+2\times(12\times7)
A_{surf}=2\times35+2\times60+2\times84
A_{surf}=70+120+168
A_{surf}=358
A_{surf}=358m^{2}

Snezhnost [94]

Answer:

0.646 radians to the nearest thousandth.

Step-by-step explanation:

To convert degrees to radians we multiply by π/180

= 37 * π/180

= 0.20556π radians

= 0.646 radians to the nearest thousandth.

Which problem is solved using this model? 15÷15   3÷115    3÷15  15÷15   https://static.k12.com/nextgen_media/assets/1503272-MAT
Pie

Answer:

As the model is shown below.

As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.

The value of fifth part of each of them is 1/5.

If we consider each part of a thing as one,

So, total number of parts = 15

Total thing=3

So, the answer of the above model is 3÷ 15.

Out of all the options which are 15÷15  , 3÷115 ,   3÷15,  15÷15  →3÷15 is correct.
