Answer:
95% confidence interval: (0.5717,0.8283)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 49
p = 70% = 0.7
Alpha, α = 0.05
The confidence interval can be calculated as:
Putting the values, we get,
95% confidence interval: (0.5717,0.8283)
Answer:
Exact answer not possible: See below.
Step-by-step explanation:
The total that Tammy would pay is the sum of 2A and 5B, where A and B are the number of candies costing $2 and $5, respectively. Therefore:
2A + 2B = Total Spent
We are told Tammy spent <u>at least</u> $75, which can be written as "Total Spent > $75."
The equation becomes 2A + 5B > 75
Rearranging:
2A + 5B > 75
2A > 75 - 5B
A > (75 - 5B)/2
To find the maximum of the candy A bought, one can try different values of A and B that result in a total of at least $75. If the amount spent were $75 exactly, a solution would be 35 A (for $70), leaving $5 for 1 candy B. But we don't know the exact amount. The problems states "at least $75." As far as we know, Tammy may have spent $105, $405, $1,005, or even $4,005 (200 A and 1 B). One cannot pick a maximum simply since the maximum spent is not defined. The next possible value above $75 would be $77, which represents 36 A and 1 B candies.
You subtract c^9 - c^14 and you get c^5
then you subtract d^-7 - d^-10 and you get d^3 because negative and a negative make a positive.
so your answer is:
d^3/c^5
Between 3 and 4 cups.
Let’s find 87% of 4.
(4)(0.87)= 3.48
So in 4 cups of milk, there is 3.48 cups of water, which is between 3 and 4 cups.
