Answer:
3*w
Step-by-step explanation:
Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.
Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).
Answer:
94 Minutes.
Step-by-step explanation:Subtract 220 from 314 and you get 94. To check you add 220 to 94 and you get 314. Hope this helped.
Answer:
a) 0.0523 = 5.23%
b) 0.9477 = 94.77%
c) 0.2242 = 22.42%
d) YES
Step-by-step explanation:
This situation could be modeled with a binomial distribution where
The probability of getting exactly k “successes” in n trials is given by
Where p is the probability of “success”.
In this case we can assume that “success” is the fact that the household interviewed is tuned to Found.
So, p=0.19 and n = 14 (the households interviewed).
a)
The probability that none of the households are tuned to Found is P(X=0)
b)
The probability that at least one household is tuned to Found is
1- P(X=0) = 1-0.0523 = 0.9477 = 94.77%
c)
The probability that at most one household is tuned to Found is P(X=0)+P(X=1)
d)
According to this sample, the probability that more than one household is tuned to Found would be 100%-22.42% = 77.58%, so it does appear that the 19% share value is wrong.
Answer:
18.75
Step-by-step explanation:
got this from calculator so might be wrong
u add 25 percent to 15
Mark up value is either a fixed amount or a percentage of the total cost or selling price.
In this problem, mark up value is the percentage of the total cost.
To determine the retail price, total cost and mark up must be added.
Selling Price = Total Cost + Mark up value based on Total Cost
However, we are looking for the Total cost. Thus, our formula should be
Total Cost = Selling Price - Mark up value based on Total Cost.
Let X = total cost.
Selling Price = $8,000
Mark up vale = 6% of total cost.
X = $8,000 - 6%X
X = $8,000 - 0.06X
To get X, transfer -0.06X to the other side and change its sign from negative to positive.
X + 0.06X = $8000
1.06X = $8000
To get X, divide both sides by 1.06
1.06X / 1.06 = $8000 / 1.06
X = $7,547.17 total cost.
The problem is looking for the mark up value and since it states that the mark up value is 6% of the total cost, then:
Total Cost x 6% = Mark up value
$7,547.17 x 0.06 = $452.83 mark up value
To check:
X + 0.06X = $8000
$7547.17 + $452.83 = $8000
$8000 = $8000 equal.
