Answer:
A
Step-by-step explanation:
is the standard deviation of x.
The standard deviation is gotten by:
1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)
2. subtract the average, x bar, from each of the values, square it, and add up the difference
3. Divide that final answer by n, which is 5
4. Take the square root of the answer
<em>Now, let's find the average (x bar):</em>
<em>x bar =

#1 is b and #2 is also b ,, i think..so sorry if i’m wrong!
The quantity of deciliters of apple juice a medium bottle contain is 10 deciliters
<h3>Equation</h3>
- Large bottles = l
- Medium bottles = m
- Small bottles = s
- Total bottles in each shelf = 64
4s + 3l = 64
3s + 2l + 2m = 64
6s + 4m = 64
If
m = 10
s = 4
l = 16
Check:
3s + 2l + 2m = 64
3(4) + 2(16) + 2(10)
= 12 + 32 + 20
= 64

Answer:
Step-by-step explanation:
A
The marble is red. There are 6 red marbles out of ten. So the answer is
6/10 = 0.60
B
Red: 1 3 5
Blue: 1 3
So there are 5 ways that you can draw an odd number. The problem is that they are not evenly distributed.
Red: 1/2 * 3/6 = 1/4 = 0.25
Blue: 1/2 * 2/4 = 0.25
Red + blue = 1/4 + 1/4 = 1/2
You could have gotten 1/2 by taking 5/10 but that won't always work.
C
A. (Displacement is the distance with direction that means it is a vector quantity. Here we are taking the home to grocery store +5 then grocery store to home -5)
5 - 5 = 0 Here the displacement is zero.
B. Distance is 10 miles
C. Velocity = displacement/time = 0/30 = 0 mile/min
D. Speed = distance/time = 10/30 mile/min = 8.94 m/s
