Question 1 is no doubt B, because Johnny only asked the students in his science class, not the entire school's population. As for question 2, If you could give me a picture of the actual graph, that would be fantastic. Until then, i don't think I can answer Q2 properly.

Question 1 is D.<em> </em>

It's not clear that the science class is a good sample of the school as a whole. It may be an elective or for a particular grade, making it a biased sample.

For Question 2 I'll try to create the histogram from your description.

N TOP BOTTOM

9 3 3

10 5 4

11 2 3

If that's accurate the BOTTOM, B, group has longer arms, due to a single person measuring 11 instead of 10.

Neither B or D is really a good answer making me think I transcribed the table incorrectly. I'd guess D

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
Solnce55 [7]

Answer:

The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is \mathbf{y=-\frac{2}{3}x+3 }

Step-by-step explanation:

We need to Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x

The equation in slope-intercept form is: y=mx+b where m is slope and b is y-intercept.

Finding Slope:

The both equations given are parallel. So, they have same slope.

Slope of given equation y= - 2/3x is m = -2/3

This equation is in slope-intercept form, comparing with general equation  y=mx+b where m is slope , we get the value of m= -2/3

So, slope of required line is: m = -2/3

Finding y-intercept

Using slope m = -2/3 and point (-3,5) we can find y-intercept

y=mx+b\\5=-\frac{2}{3}(-3)+b\\5=2+b\\ b=5-2\\b=3

So, we get b = 3

Now, the equation of required line:

having slope m = -2/3 and y-intercept b =3

y=mx+b\\y=-\frac{2}{3}x+3

The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is \mathbf{y=-\frac{2}{3}x+3 }

Find the distance between the points (0,2)and (-5,-9)The answer must be a whole number or a fully simplified radical expression
LiRa [457]

Answer:

d = \sqrt{146}

Step-by-step explanation:

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(-5-0)^2+(-9-2)^2}\\d= \sqrt{(-5)^2+(-11)^2}\\d= \sqrt{25+121}\\d= \sqrt{146}

Please help, please help
zmey [24]
Answers:
x=22
x+4=26
6x=132

Explanation:
We learned from the question that all of the angles in a triangle add up to 180 degrees.

180=angle+angle+angle

When we plug in the values that the question gives us for the angles, we get this equation:

180=x+6x+(x+4)

After solving this equation, we get 22 as the value of x (The process of solving that equation is in the picture attached).

To solve for (x+4), we plug in the value of x, which is 22 and add 4.

(x+4)
=(22+4)
=26

And finally, to solve for 6x, we plug in 22 again:

6x
=6*22
=132

Hope this helps!
