Answer:
1 because having anything power 0 is 1
1) Find the graph of a line passing through (-1, 4) and (2, 0).
The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:
The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:
To find b, substitute x and y for one of the given coordinate pairs:
0 = (-4/3)(2) + b
0 = -8/3 + b
8/3 = b
Substitute the b value into the equation to finish the line:
Answer:
36 members
Step-by-step explanation:
Given that:
Woodwind section = 1/4 of the total band
Members if woodwind section = 9
Total members of band (m) :
1/4 * m = 9
m/4 = 9
Multiply both sides by 4
m/4 * 4 = 9 * 4
m = 36
Total band members = 36
Answer:
The answer is 2.9, or 29/10
(D)
I hope this helps!
Step-by-step explanation:
you have to find a common denominator first
9 2/10-6 3/10
then you subtract
2 9/10, or 2.9, or 29/104
There are four mutually exclusive groups, therefore, the probability of one item being classified into any of the four groups is 1/4 or 0.25.
The expected number of items is calculated as the product of the probability and the total number of observations. For this problem, the probability of an item being classified to group 1 is 0.25 and the total number of observations is 400. Therefore, the expected number of items is
The expected number is
100.
