Answer:
total ages = 60
Generally, if the mode is 8 would mean there are more than one age of 8
suppose there are two with age 8,
leaving 44 for the other 4
(11 for the average of the remaining 4)
could have 9 and 13, and 8 and 14
so we could have:
8,8,8,9,13,14
or we could have:
8,8,9,10,12,13
check:of the 1st answer
mean = (8+8+8+9+13+14)/6 = 10
the mode is 8
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
9x is equal to 9 multiplied by x.
x=4 so it is 9 x 4
9 x 4=36
The plane can travel 1530km in
hours.
Find the Mean, Median, Mode & Range. If possible, round to the nearest tenth. 3, 8, 7, 2, 4, 8, 3, 4
Masja [62]
Answer:
Mean- 4.9
Median- 4
Mode- 3,4,8
Range- 6
Step-by-step explanation:
The mean of a sequence is the average amount. This is equal to all of the terms' sum divided by the number of terms. So, to find the mean add 2+3+3+4+4+7+8+8, which equals 39. Then, divide by 8 because that is the number of terms. Therefore, the mean is 4.9.
The median is the number in the middle of the sequence. To find the median order the sequence from least to greatest and find the middlemost number. In this case, that is 4.
The mode is the number that appears most often. In this sequence, 3, 4, and 8 all appear twice.
The range is the difference between the minimum and maximum. So, subtract 2 from 8 to get 6.
Answer:
D. 151 cu. in.
Step-by-step explanation:
Given: Cone; Radius = 4 in, Height = 9 in.
To find: The volume of the specified cone
Formula:
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by : volume = ( ) × π × r² × h.
