Answer:
7
Step-by-step explanation:
we need to first find the area
4.5 x 4 = 18
1.5 x 2 = 3
18 - 3 = 15
15/2.25 = 20/3
20/3 is 6.666666666666666666666666666666.....
6+1 = 7

The table gives the scores of 6 students from a class of 25 in a competitive exam. The point estimate of the mean score for the students is _____-
. (Round off your answer to the nearest tenth.)
Answer
593.3
Explanation
Mean is also called average. It represents the average mark of a given data.
For the question above, you to add all the marks of the students then you divide by the number of students.
Mean = (650+550+380+720+710+ 550)÷6
= 3,560 ÷ 6
=593.3333
Answer to the nearest tenth = 593.3
The point estimate of the meanscore for the students is 593.34 if the number of observation is 6.
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We know,
Mean = (sum of observation)/(number of observation)
Sum of scores = 650+550+380+720+710+550 = 3560
Number of observation = 6
Mean = 3560/6 = 593.33 = 593.34
Thus, the point estimate of the meanscore for the students is 593.34 if the number of observation is 6.

Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb

▹ Answer
35x + 72y
▹ Step-by-Step Explanation
(38x + 61y) - (3x - 11y)
38x + 61y - (3x - 11y)
38x + 61 y - 3x + 11y
35x + 61y + 11y
35x + 72y
