Answer:

1 - 1/10

Step-by-step explanation:

As strange as it may seem, the easiest way to answer this question is to calculate the probability of selecting an elephant first and then to subtract this probability from 1:

Adding up the Numbers of animals, we get 12+4+3+11, or 30. The probability of selecting an elephant is thus 3/30, or 1/10.

Thus, the probability of NOT selecting an elephant is 1 - 1/10 (Answer A).

Answer:

Step-by-step explanation:

x^2 + (x+3)^2 = 117

x^2 + x^2+6x+9 =117

2x^2 + 6x - 108 = 0

(2x-12)(x+9)=0

x=-9,6

x cannot be negative therefore, x = 6

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in 3 hours and 6 minutes?

Veronika [31]

Answer:

He will bike 26.87 miles.

Step-by-step explanation:

Given:

Jordan bikes at a speed of 8 2/3 mph.

Now, to find the distance he will bike in 3 hours and 6 minutes.

Speed = $8\frac{2}{3}=\frac{26}{3}\ mph.$

Time = 3 hours and 6 minutes

= $180+6=186\ minutes.$

As, 60 minutes = 1 hour.

= $\frac{186}{60} =3.1\ hours.$

So, to get the distance we put formula:

$Distance=speed\times time$

$Distance=\frac{26}{3} \times 3.1$

$Distance=\frac{80.6}{3}$

$Distance=26.87\ miles.$

Therefore, he will bike 26.87 miles.
