Answer:

C) robin, sparrow, pelican

Step-by-step explanation:

Each of the two events given by the problem is describing a condition that must be checked according to the given table, the first event describes that it must be a bird and the second event says that it must fly.

If you refer to the table that gives you the problem you must verify that there is a verification symbol in each of the events.

In this case the verification symbol must be in the two events that condition already exists.

Therefore, the animals that have the two events verified in the table are the robin, the sparrow and the pelican.

Find the sum of the following ap .1) 1/15, 1/12, 1/10,....,to 11 terms

sertanlavr [38]

Answer:

33/20

Step-by-step explanation:

1/12 - 1/15 = 5/60 - 4/60 = 1/60

d = 1/60

a_n = a_1 + d(n - 1)

a_11 = 1/15 + (1/60)(11 - 1)

a_11 = 1/15 + 1/6

a_11 = 4/60 + 10/60

a_11 = 14/60

a_11 = 7/30

a_12 = 14/60 + 1/60

a_12 = 15/60

a_12 = 1/4

s_n = n(a_1 + a_n)/2

s_11 = 11(1/15 + 7/30)/2

s_11 = 11(2/30 + 7/30)/2

s_11 = 11(9/30)/2

s_11 = 99/60

s_11 = 33/20

An american roulette wheel has 38 slots, of which 18 are red, 18 are black, and 2 are green (0 and 00). if you spin the wheel 38

Alexeev081 [22]

Intuitively, one would think the ball would land in the green spot 2 out of the 38 times, since there are 38 slots and 2 are green.

The probability that it lands in a green section is 2/38. Multiplying this by the number of times the experiment is performed, we get (2/38)(38) = 2.

Help me ASAP PLEASE

Answer:

Your(my) number is 40

Step-by-step explanation:

I. Given 80/something, + 13, * 5 = 75 when x is something

So [ $\frac{80}{x}$ + 13 ]5 = 75

[ $\frac{400}{x}$ + 65] = 75

$\frac{400}{x}$ = 75 - 65

$\frac{400}{x}$ = 10

400 = 10x

x = 40

II. Prove by replace 40 in x

[(80/40) + 13]5 = 75

[2 + 13] 5 = 75

(15)5 = 75

75 = 75 true

Ask me for anything.
