Ans this question any one

Answer:

None of them

Step-by-step explanation:

A polynomial must have a pronumeral that is to the power of an integer, and you can't divide by a variable such as 2/x so for

a) there is a $\sqrt{x}$ which means it's not a polynomial as $\sqrt{x}$ is the same as $x^{1/2}$

b) The second term is being divided with a variable so that can't be a polynomial

c) There is a $\sqrt{3x}$ so it can't be a polynomial

d) There is a $\sqrt{y}$ so it can't be a polynomial

Calculate the probability of all three events occurring.

beks73 [17]

Answer:

even = 1/2

prime = 1/2

multiple of 5 = 1/6

Step-by-step explanation:

probability is the chances of obtaining a certain result out of many attempts.

when rolling a die, the maximum number of results you can get is 6

Then, calculate how many times each of the occurrences appear(even, prime or multiples of 5)

Even = There are only 3 even numbers from 1 to 6

Prime: There are only 3 primes from 1 to 6

Multiples of 5 = There is only one multiple of 5.

Now you present each of this out of 6:

Even: 3/6 = 1/2

Prime: 3/6 = 1/2

Multiple of 5 = 1/6

This can also be presented as a decimal or percentage:

Even: 50% = 0.5

Prime: 50% = 0.5

Multiple of 5 = 16.67% = 0.16

Hope this helps.

Good Luck

If the probability that a bird will lay an egg is 75%, the probability that the egg will hatch is 50%, and the probability that

garik1379 [7]

Answer: (A) 30%

Step-by-step explanation:

Given : The probability that a bird will lay an egg =0.75

The probability that the egg will hatch =0.50

Now, the probability that the egg will lay an egg and hatch = $0.75\times0.50$

Also,The probability that the chick will be eaten by a snake before it fledges =0.20

Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80

Now, the probability that a parent will have progeny that survive to adulthood will be :-

$0.75\times0.50\times0.80=0.30=30\%$

Hence, the probability that a parent will have progeny that survive to adulthood = 30%
