Answer:
a. 26° C
b. 40m
c. Yes
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
a. What was the approximate temperature at a depth of 70 m? At the surface?
26° C
b. At what depth was the temperature a little more than 27°C?
40 m
c. Do the points in the scatter plot show a relationship? Explain your thinking.
Yes, the scatter plot show a relationship between the depth and the temperature of Lake Turkana. It shows a negative correlation between the two variables. The deeper the lake is, the cooler the temperature .
Hope it will find you well.

Answer:
c
Step-by-step explanation:
Answer:
Approximately
n = 21 years
Step-by-step explanation:
Original height of the tree = 4 1/2 feet
Final height of the tree = 40 feet
Common difference = 1 3/4 feet per year
The data shows the question is an arithmetic progression
Tn = a + (n-1) d
Tn = 40
a = 4 1/2
d = 1 3/4
n = ?
Tn = a + (n-1) d
40 = 4 1/2 + ( n - 1) 1 3/4
40 = 9/2 + (n - 1) 7/4
40 = 9/2 + 7/4n - 7/4
40 = 18-7/4 + 7/4n
40 = 11/4 + 7/4n
40 - 11/4 = 7/4n
160-11/4 = 7/4n
149/4 = 7/4n
Divide both sides by 7/4
n = 149/4 ÷ 7/4
= 149/4× 4/7
= 149/7
n = 21.29 years
Approximately
n = 21 years
There were 20 football players in the room. Because the ratio of football players to soccer players was 5 to 7, that meant that, should the ratio represent the actual number of football players in the room, there would be 12 football players in the room. However, the ratio has to be set equal to accomodate the 48 football players, therfore the 12 hypothetical players in the room would have to be multiplied by 4 to equalize. But that also means that everything else in the ratio will have to be multiplied by 4 to truly balance the ratio. Since there were 5 out of 12 football players, and there are actually 48 football players, and 12 times 4 equals 48, then 5 times 4 should give us our actual number of football players. Finally, some basic math will tell you that because 5 times 4 equals 20, and we can say that there are actually 20 football players in the room.
