Answer:
Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart
Step-by-step explanation:
We want construct a stem and leaf plot and we want to find the measure least useful.
And for this case if we analyze the option we have:
Range: That very useful and it can be extracted from the stem and leaf plot
Median: It could be easy to find it with the stem leaf plot
Mode: With a stem leaf plot we can find easily the most repeated value
Mean: For this case would be not useful since in the stem leaf plot is difficult to find this measure with this chart
Answer:
x=1 or x=-3 i<em>like </em>
Step-by-step explanation:
subtract -x-4 from both sides and left side of equation and the last step is set factor equal to 0
Answer:
girls = 125
boys = 87
Step-by-step explanation:
Total number of students in the 8th grade class = 212
Let g represent girls and b represent boys
Number of girls, g = 2b -49
Note that boys and girls in the class give a total of 212
So,
g + b = 212 ....eq 1
Slot in the value of g in the equation
2b - 49 + b = 212
2b + b - 49 = 212
3b - 49 = 212
Add 49 to both sides
3b - 49 + 49 = 212 + 49
3b = 261
Divide both sides by the coefficient of b which is 3
b = 87
Now that we've found the number of boys, let's find that of girls
We will slot in the value of b in eq 1
g + 87 = 212
Subtract 87 from both sides
g + 87 - 87 = 212 - 87
g = 125
So the number of boys is 87 and the number of girls is 125
Yeah that's right I'm pretty sure that's the work u do so u r not wrong ok so relax
y=-3x+4 = x = 4/3
y=3x-2 = x =2/3
