Answer:
3 3/6 or 3 1/2 or 3.5
Step-by-step explanation:
The answer is 4!·3!=144
the ! is interesting. it goes like this:
1!= 1
2!=2
3!=6
4!=24
this happens because each ! will multiply the number by the answer to the number before it. it is easier to show you though.
1!=1 because 0!=1, and 1*1=1
2!=2 because 1!=1, and 2*1=2
3!=6 because 2!=2, and 3*2=6
4!=24 because 3!=6, and 4*6=24.
so 4!=[(24)*(6)]=3!
24*6=144
Answer:
1/2
Step-by-step explanation:
I think it is 2 because 6 are adult users of smartphone and the probability is 3. So 3 that is the probability over the total, that is 6.So, 3/6 is 1/2. Hope it was helpful.
Answer:
(3 - x)(3 + x)(2x + 1)
Step-by-step explanation:
18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )
= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term
= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )
= (3² - x²)(2x + 1)
= (3 - x)(3 + x)(2x + 1)
Answer:
t ≤ -7
Step-by-step explanation:
−4t≥28
−4/4 * t ≥ 28/4
−1 * t ≥ 7
-t ≥ 7
