Answer:
dog food: so you take 48 (the amount of dog food can in a box) times 30 (the amount of boxes he will be ordering) and that equals 1440 dog food cans
cat food: so you take 112 (the amount of cat food) times 25 (the amount of boxes he will be ordering) and that equals 2800
so you take 1440 (dog food cans) plus 2800 (cat food cans) = 4240 cans of pet food in all
Step-by-step explanation:
U - v = (3 - 4i) - (3i + 6) = 3 - 4i - 3i - 6 = -3 - 7i
Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.
Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
