Answer:
a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
explanation: A histogram is a chart that shows frequencies for. intervals of values of a metric variable. Such intervals as known as “bins” and they all have the same widths. The example above uses $25 as its bin width. So it shows how many people make between $800 and $825, $825 and $850 and so on.
Answer:
48 members
Step-by-step explanation:
Add the numbers in the ratio: 4+4=8
Divide: 24boys/4=6
Multiply: 6*8=48
Now we know there are 48 people. Take it a step forward..how many girls?
EASY!
4*6=24 girls
We know this works because 24+24=48
*Note: the 4's come from the ratio*
Answer:
i guess 87
Step-by-step explanation:
87.2
nearest must be 87
if 87.5
nearest is 88
b = 1/6
Explanation:
3x-y=4 ...1st equation
Rewriting in slope- intercept form:
y = 3x - 4
2y+4bx=1
Rewriting in slope- intercept form:
2y = -4bx + 1
y = -4bx/2 + 1/2
Equation of line: y = mx + c
where m = slope, c = intercept
For a line to be perpendicular to another, the slope of one will be the negative reciprocal of the slope of another.
Slope of the 1st equation = 3
m = 3
reciprocal of 3 = 1/3
negative reciprocal of 3 = -1/3
Slope of the 2nd equation = -4b/2
we equate both slope:
negative reciprocal of 3 = -4b/2
-1/3 = -4b/2
cross multiply:
-1(2) = 3(-4b)
-2 = -12b
Divide both sides by -12:
-2/-12 = -12b/-12
b = 1/6
Hence, the value of b that makes the lines perpendicular is 1/6
Answer:
1/3%
Step-by-step explanation:
33 1/3% - 33% = 1/3% thats your difference
