Given:
μ = 70, the mean
σ = 10, the standard deviation
The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5
From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.
Answer: 30th
Answer:
It is possible, because the two shortest sides have to add up to be more than the longest side, and 8 + 12 = 20, which is more than the longest side of 17.
So yes, I agree with Bear.
Answer:
12
Step-by-step explanation:
So, the 24cm, is the diameter, a little circle autonomy here, the diameter is the length across the circle, and the radius is to the mid point, or half-way point, which means that the radius is half the diameter, so, 24 ÷ 2 = 12
hope this helps:)
Integers are numbers without decimals
The integers could you have multiplied are 9 and 2
Let the numbers be x and y
So, we have:
Increase x by 1 and reduce y by 1.
So, we have
Open brackets
Subtract xy from both sides
Collect like terms
Rewrite as:
The above means that, the difference between the integers is 7.
There are several integers that fit the above <em>description</em>;
One possibility is: 9 and 2
