2x + 5y = 20
5y = -2x + 20
y = -2/5x + 4. The slope here is -2/5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of -2/5, we flip the slope and change the sign. So our perpendicular line will have a slope of 5/2.
y = mx + b
slope(m) = 5/2
(10,-4)....x = 10 and y = -4
now we sub and find b, the y int
-4 = 5/2(10) + b
-4 = 25 + b
-4 - 25 = b
-29 = b
so our perpendicular equation is : y = 5/2x - 29 <==
The possible additional amount that Dan will need to spend would be = $12
<h3>What is addition?</h3>
Addition is defined as the summation of two or more figures to achieve a common value.
The amount of money Dan plans to spend on gifts and not exceeding = $27
The total amount of money that Dan has spent so far = $15
Therefore, the amount of money that Dan may possibly spend would be = 27-15 = $12.

The answer is A.
The example sort of doesn't make sense but in essence what you would do is divide the 366mins by 60 min (366/60) in order to know how many hours are in 366min.
Answer:
The option which is an exception is;
c) The sample sizes are large
Step-by-step explanation:
Here the requirement to perform a two sample t procedure are as follows;
1. The two samples have equal variance, hence the variance should be known
2. The samples for which the two sample t procedure is performed must be independent
3. The data are in alignment with the normal distribution probability
4. The samples are random samples taken from the different respective population
Since the sample size is known, we do not assume that the sample size are large.
Therefore options a), b) and d) are all correct except option c).
All we have to do is divide the money she spent on fruit by the total and multiply that by 100.
18÷45
.4×100
40
So, Carmen spent 40% of her money on fruit.
