Question 7 (5 points)
Joelle sold candles in her store. This chart shows the number of candles she sold in
one week during store hours.
Day Number of Candles
Wednesday 4
Thursday 12
Friday 4
Saturday 6
Sunday 9
What is the median number of candles Joelle sold in one week?
Answer: 6
That chart is confusing ash, but median just refers to the middle value. Just put them in order (4,4,6,9,12) and then find the middle. In this case it's easy as there are an odd number of values. But if you have another question where there are an odd number, for example (4,4,6,10,12,15) find the two middle numbers, 4 and 9, add them (6+10=16) and then divide by 2 to find the number in between those two. (16/2=8)

Exact value using sum and difference, Sin75°
Answer:
sin(75°) = [tex]\frac{\sqrt{2}+\sqrt{6} }{4}[/tex]
Step-by-step explanation:
Given: sin(75°)
Rewrite: sin(30° + 45°)
Use sum and difference identity:
sin(α + β) = sinαcosβ + cosαsinβ
sin(30°+45°) = sin(30°)cos(45°) + cos(30°)sin(45°)
sin(30°+45°) = (1/2)(√2 / 2) + (√3 / 2)(√2 / 2)
sin(30°+45°) = (√2 / 4) + (√6 / 4)
sin(30°+45°) = [(√2 + √6) / 4]
sin(75°) = [(√2 + √6) / 4]
insert 7 arithmetic means between 4 and 8
Answer:
mafi mallum
Step-by-step explanation:
The 7 arithmetic means between 4 and 8 are
9/2, 5, 11/2, 6, 13/2, 7, and 15/2.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
First term = 4
This means,
a = 4
9th term = 8
This means,
a + (9 - 1)d = 8
4 + 8d = 8
8d = 8 - 4
8d = 4
d = 4/8
d = 1/2
Now,
2nd term = 4 + (2 - 1)1/2 = 4 + 1/2 = 9/2
3rd term = 4 + 2 x 1/2 = 4 + 1 = 5
4th term = 4 + 3 x 1/2 = 11/2
5th term = 4 + 4 x 1/2 = 4 + 2 = 6
6th term = 4 + 5 x 1/2 = 13/2
7th term = 4 + 6 x 1/2 = 4 + 3 = 7
8th term = 4 + 7 x 1/2 = 15/2
Thus,
The arithmetic sequence is 4, 9/2, 5, 11/2, 6, 13/2, 7, 15/2, 8.

Find an equation for the inverse for each of the following.
Answer:
To solve these first swap x and y, solve for y and name it inverse function3. y = -8x + 2
x = -8y + 28y = -x + 2y = -x/8 + 2/8y = -(18)x + 1/4f⁻¹(x) = -(18)x + 1/4
-----------------------------------------
4. y = (2/3)x - 5
x = (2/3)y - 5(2/3)y = x + 5y = (3/2)x + (3/2)5y = 1.5x + 7.5f⁻¹(x) = 1.5x + 7.5

A construction crew is lengthening a road. The road started with a length of 54 miles, and the crew is adding 4 miles to the road each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use the equation to find the total length of the road after the crew has worked 39 days
Answer:
54 + 4D = L
After 39 days, the total length of the road will be 210 miles.
Step-by-step explanation:
Given that a construction crew is lengthening a road, and the road started with a length of 54 miles, and the crew is adding 4 miles to the road each day, to write an equation in which L represents the total length of the road ( in miles), and D represent the number of days the crew has worked, and then use the equation to find the total length of the road after the crew has worked 39 days, the following calculations should be performed:
54 (initial length) + 4D = L
54 + 4D = L
Thus, if the crew worked 39 days, the equation would be applied as follows:
54 + 4x39 = L
54 + 156 = L
210 = L
Therefore, after 39 days, the total length of the road will be 210 miles.

A national organization sets out to investigate the change in prevalence of HIV since the last census in 2010. A total of 4,706 participants were interviewed and a total of 468 responses were confirmed to be HIV positive. Assume that the data from the census indicated that the prevalence of HIV in the particular population was 7.5%.
Required:
Test if the proportion of the prevalence of HIV has changed (is equal to 7.5%). Use α = 0.05.
Answer:
As can be seen, there has been a rise in the proportion of the population with HIV positive, from 7.5% to 9.94%.
Step-by-step explanation:
Given that a national organization sets out to investigate the change in prevalence of HIV since the last census in 2010, ya total of 4,706 participants were interviewed and a total of 468 responses were confirmed to be HIV positive, assuming that the data from the census indicated that the prevalence of HIV in the particular population was 7.5%, to determine if the proportion of the prevalence of HIV has changed (is equal to 7.5%) the following calculation should be performed:
4706 = 100
468 = X
468 x 100/4706 = X
46,800 / 4,706 = X
9.94 = X
Therefore, as can be seen, there has been a rise in the proportion of the population with HIV positive, from 7.5% to 9.94%.

Pamela is 14 years younger than Jiri. The sum of their age is 70. What is Jiri’s age?
Answer:
56 ...
Step-by-step explanation:
70-14 = 56
Since it’s the sum of their age it’s just jiri’s age plus Pamela’s so you just subtract Pamela’s age from the total sum. And that would make jiri 56. (Sum means the total from adding) So if you do the problem over again. “The sum of 56 and 14” it would take you back to the question you have now. This is inverse addition.
Answer:42
Step-by-step explanation: you split 70 in half, 35 and 35. Then you add 7 to one (Jiri) and subtract 7 from one(Pamela). You get 42 and 28. To check you do 42-28=14 and 42+28=70.
