Answer:
Mean = 44.
Mean is the average.
Add all numbers:
(43 × 3) + (44 × 5) + (45 × 2) + 46
(129) + (220) + (90) + 46
= 485
Divide by number of points:
485 ÷ 11 = 44.090909 (09 repeating)
Round to 44.
Median = 44
Median is the middle-most number.
Line all the values up:
43, 43, 43, 44, 44, 44, 44, 44, 45, 45, 46
'Cross' numbers off from each side until you reach the middle- 44.
Mode = 44
Mode is the number that appears most often. 43 appears three times, 44 appears five, 45 appears twice, and 46 appears once. Five was the greatest reoccurrence. Therefore, 44 is the mode.
Range = 3
Range is the distance between the smallest value and the largest value.
Smallest number: 43
Largest number: 46
46 - 43 = 3
Answer:
The surface area is 
Step-by-step explanation:
The surface area of a rectangular prism is calculated using the formula;
![S.A=2[lw+lh+wh]](https://tex.z-dn.net/?f=S.A%3D2%5Blw%2Blh%2Bwh%5D)
The length of the rectangular prism is 
The height is 
The width is 
The surface area
![S.A=2[10(8)+10(6)+8(6)]](https://tex.z-dn.net/?f=S.A%3D2%5B10%288%29%2B10%286%29%2B8%286%29%5D)
![S.A=2[80+60+48]](https://tex.z-dn.net/?f=S.A%3D2%5B80%2B60%2B48%5D)
Answer:
a=3
Step-by-step explanation:
Answer:
99 points
Step-by-step explanation:
Average of a data a is the sum of the data divided by the number of data.
Average = sum of data ÷ number of data
A = T/n .....1
For the average of 5 test to be 90.
The total sum of score must be;
Number of tests n = 5
Average A = 90
Substituting into equation 1
90 = T/5
T = 90×5 = 450 points
The total score must be equal to 450 point to have an average of 90 points
The sum of the first four test is;
88+84+88+91 = 351
Let x represent the first score,
351 + x = 450
x = 450 - 351
x = 99 points
The minimum score she can get in the fifth test is 99 points
