Answer:
34.134%
68.268%
Step-by-step explanation:
Given that:
Mean (m) = 500
Standard deviation (s) = 100
Percentage between 500 and 600
P(500 < x < 600)
P(x < 600) - P(x < 500)
Z = (x - m) / s
P(x < 600)
Z = (600 - 500) /100 = 1
P(x < 500)
Z = (500 - 500) / 500 = 0
P(Z< 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%
B.) Between 400 and 600
P(x < 400)
Z = (400 - 500) /100 = - 1
P(x < 600)
Z = (600 - 500) / 500 = 1
P(Z< 1 ) - P(Z < - 1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%
= 68.268%
Ok so if the <span>6÷3 does not have a bracket, then the answer would be:
</span><span>6÷3/5 = 6 * 5/3 = 2 * 5 = 10
Hope this helps!</span>
B is the correct answer I think
Answer:
This can't be answered as the data of Tom and Susan's box plots aren't shown.
Answer:
The value of x is 
.
Step-by-step explanation:
Given expression is:
We have to solve this for x.
First we will multiply both sides of the equation by 3
2(x-2) = 12x
2x-4=12x
Now we will be subtracting 2x from both sides of the equation
2x-2x-4=12x-2x
-4=10x
10x=-4
Dividing both sides by 10
Hence,
The value of x is .
