Answer:
2t = 1 / 2
Step-by-step explanation:
2t = 1 / 2
t = 1 / ( 2 x 2 )
t = 1 / 4
1. There are 16 ounces in a pound. So you need to divide 48 by 16 to get the number of pounds of chocolate (YUM!) to buy. I get 3 pounds (extra yum!!!).
2.There are 1,000 millilitres in a litre, so 1 millilitre is one thousandth of a litre. The answer is litre.
3. You question is a bit blurry, but I think it says, " (65 divided by 5 ) -4".
In this case, the answer is: divide 65 by 5, then subtract 4.
Answer:
a) 0.623 (62.3%)
b) 0.764 (76.4%)
c) 0.6 (60%)
Step-by-step explanation:
a) defining the event F= the product is favorable , then the probability is
P(F) = probability that the study was sponsored by food industry * probability that the product is favorable given that it was sponsored + probability that the study had no corporate ties * probability that the product is favorable given that it was not sponsored = 0.70 * 0.68 + 0.30 * 0.49 = 0.623
b) for conditional probability we use the theorem of Bayes , then defining the event S= the study was sponsored by the food industry , we have:
P(S/F)=P(S∩F)/P(F)= 0.70 * 0.68/0.623 = 0.764 (76.4%)
where
P(S∩F)=probability that the study was sponsored by food industry and the product was found favorable
P(S/F)=probability that the study was sponsored by food industry given that the product was found favorable
c) for U= the product was found unfavourable , doing the same procedure as in a)
P(U)= 0.70 * 0.10 + 0.30 * 0.35 = 0.175
and the corresponding conditional probability is
P(N/U)=P(N∩U)/P(U)= 0.30 * 0.35 / 0.175 = 0.6 (60%)
where N represents the event = the study had no industry funding
Question
a) What is the decay factor?
b) What is the percent decrease?
c) Estimate the number of black and white TV's sold in 1999.
Answer:
a. Decay factor = 0.85
b. Percent decrease = 15%
c. 19.363 million TVs were sold
Step-by-step explanation:
Given
Solving (a): The decay factor
An exponential function has the form
Where b is:
By comparison:
Solving (b): Percentage decrease:
Percentage decrease P is calculated as follows:
Substitute 0.85 for b
Convert to percentage
Solving (c): TVs sold in 1999
First, we need to determine the value of t for 1999
In 1997, t= 0
In 1998, t= 1
In 1999, t= 2
So, we substitute 2 for t in:
Answer:
Her salary of 2600 per month doesn't change, what does change is the amount of money she makes dependent upon her dollar amount in sales. She earns 7% of her sales, which is our unknown. And we know that she would like make at least $2900 this month. That means that it's ok to make exactly 2900 and it's of course ok to make more than 2900 but it's not ok to make less than that. So our inequality sign is greater than or equal to. Now let's set it up as an inequality: where of course, as stated earlier, the unknown is her sales in dollars. It doesn't look like you need to solve this.
