200 +5(200) = 1200 mochas a week in total
They sold 1000 iced mocha in a week
200 x 4=800 hot mochas in 4 weeks
1000 x 4=4000 iced mochas in 4 weeks
They sold 4000-800= 3200 more iced mochas in 4 weeks

b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|=
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
Exact Form:
9/10
Decimal Form:
0.9

Answer: If Gregg colored none of the numbers blue, then obviously the chance the of his coloring being factorific would be zero.
If Gregg colored all of his cards blue, then again the chance would be 100%. This is because at least one of the cards is blue and all the divisors are blue.
On the other hand if only some of the cards are blue, then are numerous possibilities for the probability. You would have to create a chart and analyze each option to make sure the divisors were also blue.
