=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28
This can be factored/simplified by dividing everything by 7
=7(m - 4)
Hope this helps! :)
Angle MNO is 90, it’s just the top right corner
Answer:
its 12
Step-by-step explanation:
you find whats closest for example, 10 squared is 100.
100 is close to 144
and 11x11= 121
so you would do 12
12x12 is 144
Answer:
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
Step-by-step explanation:
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 180, σ = 8.
For x = 185:
z = (185 - 180)/8 = 0.625
For x = 190:
z = (190 - 180)/8 = 1.25
P(185 < x < 190) = P(0.625 < z < 1.25) = P(z < 1.25) - P(z < 0.625) = 0.8944 - 0.7324 = 16.2%
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
Subtract to find the difference:
2000 - 500 = 1500
Divide the difference by the original population:
1500 / 500 = 3
Multiply that by 100 to get the percentage:
3 x 100 = 300%
