The correct answer to this question is 7.75
topjm [15]2 years ago

Answer:

Range = 7

Mean = 7.75

Assumption: Most students will have 7 or 10 letters in their last name

Step-by-step explanation:

Range = Largest - Smallest

           = 10 - 3

           = 7

Mean = Add the total numbers up to get a total / numbers in the series

          = (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)

          = 7.75

There are 3 times as many dogs as cats.
vazorg [7]

Answer:

there are 12 dogs.

Step-by-step explanation:

d= dogs              now plug in the 4 into your equation.

c= cats                  d=3(4)

d+c=16                   d=12

3c+c=16

4c=16                        SO THEREFORE THERE ARE 12 DOGS :)

c=4

Find an equation of the tangent line to the graph of
lakkis [162]

Answer:

y + 4 = -3 (x - 5)

In other words,

y = -3 x + 11

Step-by-step explanation:

The slope of the tangent line to y = g(x) at x = 5 is the same as the value of g'(x). g'(5) = 3. Therefore, 3 will be the slope of the tangent line.

The tangent line goes through the point of tangency (5, g(5)). g(5) = -4. Therefore, the tangent line passes through the point (5, -4).

Apply the slope-point form of the line. The equation for a line with slope <em>m</em> that goes through point (a, b) will be y - b = m(x - a). For the tangent line in this question,

  • m = 3,
  • a = 5, and
  • b = -4.

What will be the equation of this line?
