3 0

Answer:

1, 3, 5

You can tell by looking that her science mean is greater than her math mean.

The higher range number means that her scores in math are more varied and spread out than her science scores.

You can tell by looking that the median scores are the same.

Perpendicular to the line 2x-5y=-11; passes through (7,5)

Westkost [7]

Answer:

$y=-\frac{5}{2}x+\frac{45}{2}$

Step-by-step explanation:

The slope intercept form of a line is given as:

y = mx + c

Where m is the slope and c is the y-intercept

Let's rearrange the equation given in this form:

2x - 5y = -11

5y = 2x + 11

y = 2/5 x + 11/5

So the slope is 2/5

Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2

Thus, equation would become: y = -5/2x + c

Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,

$y=-\frac{5}{2}x+c\\5=-\frac{5}{2}(7)+c\\5=-\frac{35}{2}+c\\c=5+\frac{35}{2}\\c=\frac{45}{2}$

Thus, the equation of perpendicular line is:

$y=-\frac{5}{2}x+\frac{45}{2}$

ASAP WILL MARK BRAINLEST

Brut [27]

Answer:

1296π m^3

Step-by-step explanation:

The volume of a cylinder is given by

V=πr^2h

We are given the diameter. To find the radius, divide the diameter in half.

r = d/2 = 24/2 = 12

Substituting in what we know

V = pi * (12)^2 * 9

V = pi *1296 m^3

What is the slope of the line that passes through the points (0,6) and (4,-1)

wlad13 [49]

To find the slope between the points, you would go through this process
(-1-6)/(4-0)
And we get
(-7)/4
Aka
-(7/4) which is our slope
