torisob [31]

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

Work out the perimeter​
Tasya [4]

Answer:

46CM

Step-by-step explanation:

Perimeter = S + S + S + S + S + S + S +S

Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2

Perimeter = 46 cm

The other 4 measurements:

5 is from the other side labelled 5 this is because they are equal.

8 is from the other side labelled 8 this is because they are equal too!

The twos are from the difference between 9 and 7.

♦HURRY PLEASE!!! ♦<br><br> ↓<br> Don't worry about the answer choice that is highlighted : )
givi [52]

Answer:

B: {(3,1), (7,9)}

Step-by-step explanation:

For equation 2x-y=5, we can isolate y, so it's easier to solve later:

y = 2x - 5

y = (x - 4)^2

Now, notice that both equations are equal to y, so we can set them equal to each other:

(x-4)^2 = 2x-5

x^2-8x+16 = 2x - 5

x^2-10x+21=0

Now, we can factorize by finding 2 numbers that multiply to 21 and add up to -10:

(x-3)(x-7)=0

x=3 or x=7

Since B is the only one with the x values of 3 and 7, the answer must be B.

But to further check our answer, we can plug x back to any of the equations above to check for y:

(3-4)^2 = 1

(7-4)^2 = 9

Therefore, we can confirm that the answer is B.
