Solve for y. First subtract 9x to both sides. 3y=-9x+12. Now divide by 3. The answer should be y=-3x+4.

Are all integers natural numbers? Explain why?

Nitella [24]

Nope.

Natural numbers consist of 1, 2, 3, 4 and so on. Integers, on the other hand, include 0 and the opposites of natural numbers (negative values). Therefore not all integers are natural numbers. Some of them are though.

The letters in the given list are written on tiles, one letter per tile. A, B, C, F, G, I, K, L, O, P, Q, T, V, W, X, Z The 16 t

Butoxors [25]

Answer:

(a) $\frac{1}{16}$

(b) $\frac{1}{8}$

(d) $\frac{15}{16}$

Step-by-step explanation:

The letters in each tile are:

A, B, C, F, G, I, K, L, O, P, Q, T, V, W, X, Z

Total Number of tiles n(S)=16

(a)The probability of drawing any one of the letters

The Probability of drawing any one of the letters $=\dfrac{1}{n(S)}=\dfrac{1}{16}$

(b)The probability of drawing either an "F" or "P" tile

P(Either an F or a P Tile) = P(drawing an F Tile )+P(drawing a P Tile)

$=\dfrac{1}{16}+\dfrac{1}{16}\\=\dfrac{2}{16}\\=\dfrac{1}{8}$

(c)The probability of drawing a vowel

The Vowel Tiles are: A,I,O

Number of Vowels =3

$\text{P(Drawing a vowel)}=\dfrac{3}{16}$

(d)The probability of not drawing a "Q" tile

$\text{P(Drawing a Q tile)}=\dfrac{1}{16}\\Therefore:\\\text{P(Not Drawing a Q tile)}=P(Q^c)=1-\dfrac{1}{16}\\=\dfrac{15}{16}$
