Perform the indicated multiplication and addition.
900 + 20 + 0.3 + 0.007 = 920.307
Answer:
A student finds a 95% confidence interval of (16.34,18.69) for the mean number of species counted. This is a valid interval because the mean number of species or any population mean does not necessarily have to be a whole number, as stated by the student.
This given confidence interval of (16.34,18.69) helps us to simply estimate the mean species counted.
Answer:
8 years
Step-by-step explanation:
Lets write an equation for Type A
The initial value is 5 ft and the slope 12 inches
We need to have the same units, so lets change 5 ft to inches
5 ft * 12 inches / ft = 60 inches
y = mx+b
y = 12 x + 60
Lets write an equation for Type B
The initial value is 3 ft and the slope 15 inches
We need to have the same units, so lets change 3 ft to inches
3 ft * 12 inches / ft = 36 inches
y = mx+b
y = 15 x + 36
We want to know when y is the same value. We can set the equations equal.
12x + 60 = 15x+36
Subtract 12 x from each side
12x-12x+60 = 15x-12x +36
60 =3x+36
Subtract 36 from each side
60-36 = 3x+36-36
24 = 3x
Divide each side by 3
24/3 = 3x/3
8 =x
It will take 8 years for the trees to be the same height
By angle:
We can classify a triangle 4 different ways when we're judging it by it's angle(s).
Acute: A triangle where all angles are less than 90 degrees.
Obtuse: A triangle where one angle is greater than 90 degrees.
Right: A triangle where one of the angles is exactly 90 degrees.
Equiangular: A triangle where all angles are the same (60 degrees.)
We can also classify a triangle by its sides:
Equilateral: (technically the same as an equiangular triangle, in order to have 3 equal sides you must have 3 equal angles as well.)
Isosceles: Two sides are the same length, where one is not.
Scalene: All three sides are different lengths.
