A) if 18 muffins = 1 box,
1020 muffins = 1020/18 boxes
= 56.67 boxes
So they used 56 full boxes.
b) if 25 cookies = 1 bag
2820 cookies = 2820/25 bags
= 112.8 bags
So they used 112 full bags.
c) the remainders from a and b represent muffins and cookies left over.
Step-by-step explanation:
The scale factor is 12/6 = 10/5 = 2.
Answer:
13.4%
Step-by-step explanation:
Use binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, n = 16, r = 2, p = 0.25, and q = 0.75.
P = ₁₆C₂ (0.25)² (0.75)¹⁶⁻²
P = 120 (0.25)² (0.75)¹⁴
P = 0.134
There is a 13.4% probability that exactly 2 students will withdraw.
Answer:
1(5/16)=1.3125
7(5/16)=7.3125
26(5/16)=26.3125
Step-by-step explanation:
Given that 5/16=0.3125, the mixed fraction 1(5/16)=1+(5/16)=1+0.3125=1.3125
Also, 7(5/16)=7+(5/16)=7+0.3125=7.3125
Furthermore,
26(5/16)=26+(5/16)=26+0.3125=26.3125
In the same vein, given that 4/15=0.266
1(4/15)=1+(4/15)=1+0.266=1.266
17(4/15)=17+(4/15)=17+0.266=17.266
23(4/15)=23+(4/15)=23+0.266=23.266
Answer:
C
Step-by-step explanation:
when x=0, y=0, so B is impossible
when X=2, Y=1,
and thus C is correct
