Answer:
it is an integer! yes ik u know that but most teachers want it to be in the smallest group u can put it in but other than that it is a real number and it is rational! A whole number is a number that is a counting number like 0,1,2,3 a natural number is a whole number without 0 like 1,2,3 a irrational number is a number that is a repeating decimal which this number isn't

Step-by-step explanation:
The solution is, the probability that both cards are red is 5/22.
Probability can be defined as the ratio of the number of favorableoutcomes to the total number of outcomes of an event.
here, we have,
given that,
Gregg has 12 cards.
Half are black, and half are red.
i.e. red = 6 & black = 6.
He picks two cards out of the deck.
now, we have,
Probability of a red card out of 12 cards = 6/12 = 1/2
Now, probability of a red card of 11 cards = 5/11
so, we get,
Combined probability = 1/2 * 5/11 = 5/22
Hence, The solution is, the probability that both cards are red is 5/22.

Answer:
Step-by-step explanation:
Looking at the Venn diagram,
The total number of students surveyed is 7 + 5 + 8 + 6 + 2 + 4 + 3 + 6 = 41
The number of children that studies none of the subjects is 6
The number of children that study only biology is 7
The number of children that study only physics is 5
The number of children that study only physics and biology is 2
Therefore, the number of students that do not study chemistry is 6 + 7 + 2 + 5 = 20
Probability = number of favorable outcomes/total number of outcomes
Therefore, the probability that a child chosen at random does not study chemistry is 20/41 = 0.49
The number, 6.5892 , given that it ends, which fits the definition, is therefore a rational number.
A rational number is a number that can be expressed as a fraction of two integers, where the denominator is not 0. 6.5892 can be expressed as the fraction 65892/10000, which is a simplified fraction with an integer numerator and denominator.
An irrational number is a number that cannot be expressed as a fraction of two integers. Examples of irrational numbers include pi (π) and the square root of 2.
A simple reminder, Rational numbers can be written as fractions. Irrational numbers cannot be written as fractions.

Answer: cos²(θ) + sin(θ)sin(e)
Step-by-step explanation:
sin (90° - θ)cos(Ф) - sin(180° + θ) sin(e)
Note the following identities:
sin (90° - θ) = cos(x)
sin (180° + θ) = -sin(x)
Substitute those identities into the expression:
cos(x)cos(x) - -sin(x)sin(e)
= cos²(x) + sin(x)sin(e)
