What does the <span>^ mean? I feel so stupid</span>
Answer:
13
Step-by-step explanation:
104×7=728
728÷56=13
Answer:
The smallest number is 23
Step-by-step explanation:
Let x be the first number
x+1 is the next consecutive number
x+2 is the next consecutive number
The sum is
x+ x+1 + x+2 = 72
Combine like terms
3x+3 = 72
subtract 3 from each side
3x+3-3 = 72-3
3x = 69
Divide each side by 3
3x/3 = 69/3
x = 23
x+1 = 24
x+2 =25
The numbers are
23,24,25
The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.
Yes, you'd be able to play.
37/42 = .88 = 88%
So you've attended more than 85% of the practices.
