The number 12 is missing in the data set.
<u>Step-by-step explanation</u>:
- The numbers are 9,12,16,18,23.
- The missing number is assumed to be 'x'
Mean = Sum of the integers / Total number of integers.
15 = (9+12+16+18+23+x) / 6
15 = (78+x) / 6
90 = 78+x
x = 90-78
x = 12

Answer:
32 feet
Step-by-step explanation:
0 seconds after launch, the rocket is still sitting on the tower. Its height is...
y = -16(0^2) +57(0) +32
y = 0 + 0 + 32 = 32
The rocket was launched from a tower 32 feet high.
Answer:
0,75kg : 18,38
4kg : 98
Step-by-step explanation:
1) 0,75 x 24,50 = 18,38
2) 4 x 24,50 = 98
Just fix the unit at the end. :)
A+b=15.25
a+f=72.25, since f=13b
a+13b=72.25 so now we have two equation in two variables...
a+13b=72.25 and a+b=15.25 so we can say:
(a+13b=72.25)-13(a+b=15.25)
a+13b-13a-13b=72.25-198.25
-12a=-126
a=10.5 kg
So Abdul's mass is 10.5 kilograms.
